COVID-19 is 10 times deadlier for people with Down Syndrome, raising calls for early vaccination 2020-12-15T05:00:00Z If the approach works, he says, the advantage is that it will continue to do so even if the virus mutates, since interferon’s action does not depend on the structure of the virus. Why the race to find Covid-19 vaccines is far from over 2020-11-22T05:00:00Z It also directs the production of type I interferons, which are crucial to the innate, or rapid-response, immune system’s ability to fight viruses. Unraveling the Mystery of Why Children Are Better Protected from COVID Than Adults 2021-08-26T04:00:00Z Similar studies have failed to show any benefit to treating patients with interferon, and Feld acknowledged that his results need to be confirmed in a larger study. Coronavirus deranges the immune system in complex and deadly ways 2021-03-08T05:00:00Z In a second Science study, the same team or researchers found that an additional 3.5% of critically ill patients had mutations in genes that control the interferons involved in fighting viruses. 'Breakthrough finding' offers clues about why certain COVID-19 patients die 2020-11-13T05:00:00Z In August, a team led by geneticist Jean-Laurent Casanova of Rockefeller University buttressed this hypothesis with a paper showing that certain white blood cells from DS patients display extra interferon receptors on their surfaces. COVID-19 is 10 times deadlier for people with Down Syndrome, raising calls for early vaccination 2020-12-15T05:00:00Z The cells that are activated release a molecule called gamma interferon that serves as a signal of their activity. New Type of Test May Better Discern Immunity to the Coronavirus 2020-11-10T05:00:00Z “And they suppress the interferon system so dramatically that we see only minimal or no interferon production in cell cultures when there is an infection.” Unraveling the Mystery of Why Children Are Better Protected from COVID Than Adults 2021-08-26T04:00:00Z Researchers are looking for ways to treat patients who have interferon deficiencies — a group at risk for severe covid complications. Coronavirus deranges the immune system in complex and deadly ways 2021-03-08T05:00:00Z He notes that the body manufactures many types of interferons, and giving patients a different type that isn’t disabled by their genes or autoantibodies might help them fight off the virus. 'Breakthrough finding' offers clues about why certain COVID-19 patients die 2020-11-13T05:00:00Z But the elevated interferon activity seen in people with DS isn’t necessarily protective. COVID-19 is 10 times deadlier for people with Down Syndrome, raising calls for early vaccination 2020-12-15T05:00:00Z The researchers inserted a gene for a human immune protein, interferon, into the virus and then used it to infect cells from the caterpillar form of a pest called the fall armyworm moth. Will a small, long-shot U.S. company end up producing the best coronavirus vaccine? 2020-11-03T05:00:00Z If a child’s interferon system is disturbed, however—because of a hereditary defect, for example—this protective effect disappears. Unraveling the Mystery of Why Children Are Better Protected from COVID Than Adults 2021-08-26T04:00:00Z In a small study published in February in the Lancet Respiratory Medicine, doctors tested an injectable type of interferon — called peginterferon-lambda — in patients with early covid infections. Coronavirus deranges the immune system in complex and deadly ways 2021-03-08T05:00:00Z A pilot study of 98 patients published Thursday in the journal Lancet Respiratory Medicine found benefits from an inhaled form of interferon. 'Breakthrough finding' offers clues about why certain COVID-19 patients die 2020-11-13T05:00:00Z Our body's cells start releasing chemicals - called interferons - once they are being hijacked by a virus and this is a warning signal to the rest of the body and the immune system. Covid: Why is coronavirus so deadly? 2020-10-22T04:00:00Z The virus transferred the gene to the moth cells, which duly secreted human interferon. Will a small, long-shot U.S. company end up producing the best coronavirus vaccine? 2020-11-03T05:00:00Z “The interferons are extremely effective against virus infections,” explains Marco Binder of the German Cancer Research Center in Heidelberg, a co-author of the Nature Biotechnology study. Unraveling the Mystery of Why Children Are Better Protected from COVID Than Adults 2021-08-26T04:00:00Z People randomly assigned to receive an interferon injection were four times more likely to have cleared their infections within seven days than the placebo group. Coronavirus deranges the immune system in complex and deadly ways 2021-03-08T05:00:00Z Future work should test patients’ blood for genetic mutations and autoantibodies against interferon to see if they respond differently than others. 'Breakthrough finding' offers clues about why certain COVID-19 patients die 2020-11-13T05:00:00Z Interferon molecules come in several types, so it’s possible these patients could be treated with another flavor of interferon, Brodin said. Why the coronavirus is killing more men than women 2020-10-17T04:00:00Z Less data has been published on interferon, a molecule produced by the immune system in response to viruses. Remdesivir fails to prevent COVID-19 deaths in large trial 2020-10-15T04:00:00Z As an effective countermeasure, however, the novel coronavirus has its own proteins that prevent interferons from being produced. Unraveling the Mystery of Why Children Are Better Protected from COVID Than Adults 2021-08-26T04:00:00Z The treatment, which used a type of interferon not targeted by the autoantibodies Casanova discovered, had the most dramatic benefits in patients with the highest viral loads. Coronavirus deranges the immune system in complex and deadly ways 2021-03-08T05:00:00Z Around the world, scientists have launched more than 100 clinical trials of interferons. 'Breakthrough finding' offers clues about why certain COVID-19 patients die 2020-11-13T05:00:00Z But that may be difficult, he acknowledged, because interferons are most helpful early in the course of an infection, before the disease progresses to life-threatening stages. Why the coronavirus is killing more men than women 2020-10-17T04:00:00Z One find is a gene called IFNAR2 that codes for a cell receptor for interferon, a powerful molecular messenger that rallies the immune defenses when a virus invades a cell. Found: genes that sway the course of the coronavirus 2020-10-13T04:00:00Z “SARS-CoV-2 multiplies very quickly in cells, and this means that the virus proteins are also formed very quickly,” says Binder, who researches interferons. Unraveling the Mystery of Why Children Are Better Protected from COVID Than Adults 2021-08-26T04:00:00Z In the trial, those treated with interferon had similar side effects to those who received a placebo. Coronavirus deranges the immune system in complex and deadly ways 2021-03-08T05:00:00Z More experimental, and a surprise if used, is interferon, another unproven experimental treatment that is in trials to see if it can help coordinate a robust immune response. Donald Trump's steroid Covid treatment adds to confusion over health 2020-10-04T04:00:00Z The reaction should cause cells to churn out the first lines of defense, such as interferons, immune system molecules that, as the name suggests, interfere with the virus’s ability to reproduce. Why the coronavirus is killing more men than women 2020-10-17T04:00:00Z A variant in one of those genes might impair this activation, allowing the virus to flourish, and the U.K. data suggest the variant is as common and influential as the interferon genetic risk factor. Found: genes that sway the course of the coronavirus 2020-10-13T04:00:00Z Type I interferons do more than just warn the body about viruses. Unraveling the Mystery of Why Children Are Better Protected from COVID Than Adults 2021-08-26T04:00:00Z Ideally, Feld said, he would like to test interferon in older patients to see whether it can reduce hospitalizations. Coronavirus deranges the immune system in complex and deadly ways 2021-03-08T05:00:00Z Q: What about treatments that boost interferons, proteins that defend against viral invasions? How might President Donald Trump fare with COVID-19? 2020-10-02T04:00:00Z When a cell detects these invader molecules, it triggers production of an antiviral interferon protein. How the Immune System of Older Adults Like Trump Weakens with Age 2020-10-02T04:00:00Z As soon as the body detects a foreign intruder, key molecules, such as interferons and inflammation-causing cytokines, launch a wide-ranging attack. Mild to severe: Immune system holds clues to virus reaction 2020-09-30T04:00:00Z Because of the lack of type I interferons, however, the defense reaction is already in a dangerous imbalance and overshoots the target. Unraveling the Mystery of Why Children Are Better Protected from COVID Than Adults 2021-08-26T04:00:00Z In a new paper in the Journal of Experimental Medicine, Rockefeller University's Casanova has found that autoantibodies to interferon are once again to blame. Coronavirus deranges the immune system in complex and deadly ways 2021-03-08T05:00:00Z The scientists specifically looked for mutations that would impair the production of type I interferons—a set of proteins made by every cell in the body that comprise a first-line defense against viruses. One in Seven Dire COVID Cases May Result from a Faulty Immune Response 2020-09-30T04:00:00Z Monocytes from older individuals produce less interferon in response to viral infections. How the Immune System of Older Adults Like Trump Weakens with Age 2020-10-02T04:00:00Z Usually when a virus invades a cell, proteins called Type I interferons spring into action, defending the cell by interfering with viral growth. Mild to severe: Immune system holds clues to virus reaction 2020-09-30T04:00:00Z “Of all signaling systems, the interferon response causes the greatest change in the cell’s genetic activity,” Binder says. Unraveling the Mystery of Why Children Are Better Protected from COVID Than Adults 2021-08-26T04:00:00Z Casanova led a team that found three of the eight patients studied who experienced a dangerous vaccine reaction had autoantibodies that disabled interferon. Coronavirus deranges the immune system in complex and deadly ways 2021-03-08T05:00:00Z “The two papers are remarkable on multiple levels,” says Eleanor Fish, a professor of immunology at the University of Toronto, who studies interferons and was not involved in those new studies. One in Seven Dire COVID Cases May Result from a Faulty Immune Response 2020-09-30T04:00:00Z Type-I interferons are crucial for mounting a defence against many viruses. Severe COVID and shrinking Arctic sea ice 2020-09-29T04:00:00Z This leads to the expression of antiviral genes, including genes that encode members of the interferon family of proteins. b, Morehouse et al.6 shed light on a related antiviral pathway in bacteria. Bacteria sting viral invaders 2020-09-27T04:00:00Z Landmark studies published Thursday in the journal Science showed that insufficient interferon may lurk at a dangerous turning point in SARS-CoV-2 infections. DNA link behind severe COVID-19 may lead to a new treatment 2020-09-24T04:00:00Z Feld, a liver specialist, notes that doctors have long studied this type of interferon to treat other viral infections, such as hepatitis. Coronavirus deranges the immune system in complex and deadly ways 2021-03-08T05:00:00Z “One is that they identified so quickly what is going on in life-threatening cases in the context of interferon response.” One in Seven Dire COVID Cases May Result from a Faulty Immune Response 2020-09-30T04:00:00Z The researchers suggest that interferons could be used as therapies for the disease. Severe COVID and shrinking Arctic sea ice 2020-09-29T04:00:00Z Synthetic interferons, long used to treat other diseases, might help some at-risk patients, as might other therapies aimed at removing the damaging antibodies. Hidden immune weakness found in 14% of gravely ill COVID-19 patients 2020-09-24T04:00:00Z Researchers — many of them also involved in the antibody study — sequenced the genomes of 659 patients with life-threatening cases of the disease; 3.5% carried genetic variations that inhibit interferon production. DNA link behind severe COVID-19 may lead to a new treatment 2020-09-24T04:00:00Z This type of interferon causes fewer side effects than other varieties. Coronavirus deranges the immune system in complex and deadly ways 2021-03-08T05:00:00Z She notes that there was already growing evidence that interferons are important in clearing the virus, but data also indicate that SARS-CoV-2 is particularly adept at blocking the body’s interferon response. One in Seven Dire COVID Cases May Result from a Faulty Immune Response 2020-09-30T04:00:00Z Host countries say they have sought to learn from Cuba’s handling of the pandemic back home: isolating cases, tracing their contacts, screening for sufferers and swiftly applying therapeutic treatments like the antiviral agent interferon. Cuba punches above weight with 'white coat army' during pandemic 2020-09-14T04:00:00Z Type I interferons are made by every cell in the body and are vital leaders of the antiviral battle early in infection. Hidden immune weakness found in 14% of gravely ill COVID-19 patients 2020-09-24T04:00:00Z But the studies in Science indicate that various forms of interferon dysfunction may underlie as many as one in eight critical patients, and that screening and targeted treatment might prevent severe illnesses and deaths. DNA link behind severe COVID-19 may lead to a new treatment 2020-09-24T04:00:00Z Dr. Nathan Peiffer-Smadja, a researcher at the Imperial College London, said it's unclear whether this type of interferon does improve symptoms. Coronavirus deranges the immune system in complex and deadly ways 2021-03-08T05:00:00Z Zúñiga, who investigates immune responses to viruses, finds it especially “mind-blowing” that antibodies to interferons were discovered in so many patients. One in Seven Dire COVID Cases May Result from a Faulty Immune Response 2020-09-30T04:00:00Z Interferons are immune proteins that normally interfere with a virus’s life cycle — hence the name, interferon. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight covid-19. 2020-08-31T04:00:00Z In 10.2% of the patients, the researchers identified antibodies that attacked and neutralized the patients’ own type I interferon. Hidden immune weakness found in 14% of gravely ill COVID-19 patients 2020-09-24T04:00:00Z “If we manage to get them into our university medical center early enough,” Hoischen said, “our clinicians may be able to treat them with interferons.” DNA link behind severe COVID-19 may lead to a new treatment 2020-09-24T04:00:00Z Interferons are immune proteins that normally interfere with a virus’ life cycle – hence the name, interferon. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight COVID-19. 2020-08-31T04:00:00Z Because most of these antibodies appear to be directed at a type of interferon called interferon-alpha, Fish offers that such patients might respond well to treatment with interferon-beta. One in Seven Dire COVID Cases May Result from a Faulty Immune Response 2020-09-30T04:00:00Z Now, several trials are underway in the United States and elsewhere to see whether giving interferon drugs to coronavirus patients early on might prevent severe disease or hasten recovery if administered later. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight covid-19. 2020-08-31T04:00:00Z The second paper found genetic flaws in patients that led to the same end result: a grossly inadequate interferon response to SARS-CoV-2 infection. Hidden immune weakness found in 14% of gravely ill COVID-19 patients 2020-09-24T04:00:00Z Now it will examine whether adding another drug, beta interferon — which mainly kills viruses but can also tame inflammation — would improve remdesivir’s effects and speed recovery even more. Federal Study of Covid Treatments Enters a New Phase 2020-08-18T04:00:00Z Now, several trials are underway in the United States and elsewhere to see whether giving interferon to coronavirus patients early on might prevent severe disease, or hasten recovery, if administered later. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight COVID-19. 2020-08-31T04:00:00Z Both studies highlight the critical role of a class of immune system proteins called interferons, so named because they interfere with the replication of viruses. One in Seven Dire COVID Cases May Result from a Faulty Immune Response 2020-09-30T04:00:00Z Researchers caution that many questions about interferon treatments for coronavirus patients remain unanswered. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight covid-19. 2020-08-31T04:00:00Z They examined 13 genes, chosen because flaws in them impair the body’s production or use of type I interferon; mutations in the genes underlie life-threatening influenza or other viral illnesses. Hidden immune weakness found in 14% of gravely ill COVID-19 patients 2020-09-24T04:00:00Z Then the group weighed using beta interferon, which had several things going for it. Federal Study of Covid Treatments Enters a New Phase 2020-08-18T04:00:00Z Driving the trials are a spate of recent studies showing that interferons are weakest in the worst coronavirus cases. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight COVID-19. 2020-08-31T04:00:00Z She points to exploratory studies on interferon in Cuba and Wuhan, China, that showed promising effects on mortality rates and earlier clearance of the virus. One in Seven Dire COVID Cases May Result from a Faulty Immune Response 2020-09-30T04:00:00Z In France, investigators plan to test interferon treatments if cases continue to rise. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight covid-19. 2020-08-31T04:00:00Z In patients for whom blood samples were available, interferon levels were vanishingly small. Hidden immune weakness found in 14% of gravely ill COVID-19 patients 2020-09-24T04:00:00Z One test was in England, where beta interferon or a placebo was provided to 101 hospitalized patients. Federal Study of Covid Treatments Enters a New Phase 2020-08-18T04:00:00Z Normally, such provocations would cause the immune cells to erupt in a shower of interferons and other defensive molecules. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight COVID-19. 2020-08-31T04:00:00Z Once a patient develops an extreme immune reaction sometimes called a “cytokine storm,” interferons are unlikely to be of use, Fish says. One in Seven Dire COVID Cases May Result from a Faulty Immune Response 2020-09-30T04:00:00Z She said she would like the NIH-sponsored trial to answer whether giving interferon drugs to hospitalized patients is helpful, and what dosages yield the best results. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight covid-19. 2020-08-31T04:00:00Z But it’s “probably the tip of the iceberg,” says Paul Hertzog, an interferon expert at the Hudson Institute of Medical Research. Hidden immune weakness found in 14% of gravely ill COVID-19 patients 2020-09-24T04:00:00Z But the U.S. trial will be the only large rigorous trial to test beta interferon in Covid patients. Federal Study of Covid Treatments Enters a New Phase 2020-08-18T04:00:00Z Researchers caution that many questions remain unanswered about interferon’s use in coronavirus patients. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight COVID-19. 2020-08-31T04:00:00Z Some are involved in the production of interferons, key modulators of the body’s response to viruses. Why Some People Get Terribly Sick from COVID-19 2020-08-20T04:00:00Z Type I interferons are normally secreted in the body to help ward off infection by modifying the activity of the immune system. Neurodegenerative gene’s function is not all about those bases 2020-08-18T04:00:00Z But synthetic interferons won’t help patients who harbor mutations that prevent interferons from working, or those with antibodies that attack them. Hidden immune weakness found in 14% of gravely ill COVID-19 patients 2020-09-24T04:00:00Z The additional drug, beta interferon, has already been approved for treatment of multiple sclerosis, which takes advantage of its anti-inflammatory effect. Federal Study of Covid Treatments Enters a New Phase 2020-08-18T04:00:00Z In France, investigators plan to test interferon if cases continue to rise. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight COVID-19. 2020-08-31T04:00:00Z Recent evidence hints that the new coronavirus might have a way of delaying or muffling interferon, one of the earliest cytokine defenses the body mounts. Scientists Uncover Biological Signatures of the Worst Covid-19 Cases 2020-08-04T04:00:00Z These findings therefore pinpoint the specific immune defect caused by loss of C9orf72 — an increased type I interferon response. Neurodegenerative gene’s function is not all about those bases 2020-08-18T04:00:00Z Yanick Crow, a clinical geneticist at the University of Edinburgh who studies interferon signaling, calls the antibody paper “shocking,” in part because men were so much more likely than women to carry the rogue antibodies. Hidden immune weakness found in 14% of gravely ill COVID-19 patients 2020-09-24T04:00:00Z The other study, in Hong Kong, involved 127 patients who received beta interferon along with two antiviral drugs. Federal Study of Covid Treatments Enters a New Phase 2020-08-18T04:00:00Z Despite their potential, interferons may not be a panacea, scientists cautioned. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight COVID-19. 2020-08-31T04:00:00Z In a sense, each of these two perceptions of interferons is correct. An Immune Protein Could Prevent Severe COVID-19—if It Is Given at the Right Time 2020-07-28T04:00:00Z Next, McCauley et al. cultured immune cells from the bone marrow of wild-type and C9orf72-mutant mice and stimulated them with several known activators of the type I interferon response. Neurodegenerative gene’s function is not all about those bases 2020-08-18T04:00:00Z The researchers also found that blood levels of a specific interferon decreased just before participants had to be taken to intensive-care units. Coronavirus research updates: Dogs’ and cats’ infection rates mirror those of people 2020-07-23T04:00:00Z The treatment involves inhaling a protein called interferon beta, which is naturally produced to fight off infection, directly into the lungs. Daily briefing: Three vaccines show early promise for COVID-19 2020-07-20T04:00:00Z She said she would like the NIH-sponsored trial to answer whether giving interferon to hospitalized patients is helpful, and what dosages yield the best results. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight COVID-19. 2020-08-31T04:00:00Z The French researchers analyzed RNA in samples containing mixtures of immune cells, whereas the South Korean team sequenced RNA in individual cells and observed interferon differences in monocytes. An Immune Protein Could Prevent Severe COVID-19—if It Is Given at the Right Time 2020-07-28T04:00:00Z These approaches restored normal type I interferon responses and spleen sizes in the mutant mice. Neurodegenerative gene’s function is not all about those bases 2020-08-18T04:00:00Z Compared to the individuals with mild or moderate symptoms, those with severe disease produced fewer antiviral proteins called interferons and more inflammatory molecules. Coronavirus research updates: Dogs’ and cats’ infection rates mirror those of people 2020-07-23T04:00:00Z The symptoms of a seasonal flu, for example, are largely produced by the mobilization of the body’s interferon response, scientists said. New Treatment for Covid-19 Shows Promise, but Scientists Urge Caution 2020-07-20T04:00:00Z Scientists theorize that the virus’s ability to disarm interferons early on may explain other aspects of the disease, such as the out-of-control inflammation reaction that develops in some patients. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight COVID-19. 2020-08-31T04:00:00Z Multiple immune cells produce interferons and are presumably influenced by the proteins. An Immune Protein Could Prevent Severe COVID-19—if It Is Given at the Right Time 2020-07-28T04:00:00Z When they performed RNA sequencing on cells from people with ALS who harbour C9orf72 mutations, they again found an enhanced type I interferon signature. Neurodegenerative gene’s function is not all about those bases 2020-08-18T04:00:00Z Treatments that counter inflammation and increase levels of interferons could help people with the disease, the researchers say. Coronavirus research updates: Dogs’ and cats’ infection rates mirror those of people 2020-07-23T04:00:00Z Professor tenOever was a co-author of a study in May in Cell, a scientific journal, about how the virus blocks the body’s interferon response. New Treatment for Covid-19 Shows Promise, but Scientists Urge Caution 2020-07-20T04:00:00Z Some experts also suggest that a person’s ability to mobilize interferons to wage a strong immune response at the start of the infection process may predict less severe disease. The coronavirus disarms the foot soldiers of the immune system. Scientists theorize that boosting them could fight COVID-19. 2020-08-31T04:00:00Z Yet the Korean team’s single-cell profiling only looked at interferons’ effect on monocytes. An Immune Protein Could Prevent Severe COVID-19—if It Is Given at the Right Time 2020-07-28T04:00:00Z The treatment from Southampton-based biotech Synairgen uses a protein called interferon beta which the body produces when it gets a viral infection. Covid protein trial described as 'breakthrough' 2020-07-20T04:00:00Z Key players in this two-part bat immune response are interferons, small signaling molecules that got their name because of their talent for interfering with virus replication. Scientists look at why bats carry viruses yet stay healthy 2020-07-12T04:00:00Z In hamsters, Professor tenOever said, there were signs that interferon cleared the virus and blocked onward transmission. New Treatment for Covid-19 Shows Promise, but Scientists Urge Caution 2020-07-20T04:00:00Z But not everyone is persuaded that the virus itself is responsible for missing-in-action interferons. Can boosting interferons, the body's frontline virus fighters, beat COVID-19? 2020-07-08T04:00:00Z “The interferon response is a little bit tricky,” says Rudragouda Channappanavar, a viral immunologist at the University of Tennessee Health Science Center, who was not involved with the new studies. An Immune Protein Could Prevent Severe COVID-19—if It Is Given at the Right Time 2020-07-28T04:00:00Z The trial, designed to test four treatments—hydroxychloroquine, lopinavir/ritonavir, interferon beta plus lopinvir/ritonavir, and remdesivir—was announced on 20 March and enrolled its first patient in Norway 1 week later. One U.K. trial is transforming COVID-19 treatment. Why haven’t others delivered more results? 2020-07-02T04:00:00Z They’re a first line of defense for mammals in general: When cells are infected by viruses, they release various interferons as an alarm signal, as do some immune system cells. Scientists look at why bats carry viruses yet stay healthy 2020-07-12T04:00:00Z In China, the early results of a study among medical workers also showed promise, concluding that interferon nasal drops “may effectively prevent Covid-19 in medical staff.” New Treatment for Covid-19 Shows Promise, but Scientists Urge Caution 2020-07-20T04:00:00Z For starters, when given as drugs, the powerful type I interferons can have awful side effects, as patients who have taken them for months on end for cancer and other diseases know. Can boosting interferons, the body's frontline virus fighters, beat COVID-19? 2020-07-08T04:00:00Z If the viruses thwart this antiviral defense, however, the delayed interferon response becomes pathogenic—summoning too many monocytes, which secrete inflammatory molecules and cause tissue damage.
