The National Institutes of Health (NIH) (@NIH), a part of the U.S. Department of Health and Human Services, is the nation’s medical research agency — making important discoveries that improve health and save lives.
About the NIH Director
Francis S. Collins, M.D., Ph.D. (@NIHDirector) was appointed the 16th Director of NIH by President Barack Obama and confirmed by the Senate. He was sworn in on August 17, 2009. In this role, Dr. Collins oversees the work of the largest supporter of biomedical research in the world, spanning the spectrum from basic to clinical research. Here are some excerpts from the his latest blog posts with links read in entirety.
Immune T Cells May Offer Lasting Protection Against COVID-19
Much of the study on the immune response to SARS-CoV-2, the novel coronavirus that causes COVID-19, has focused on the production of antibodies. But, in fact, immune cells known as memory T cells also play an important role in the ability of our immune systems to protect us against many viral infections, including—it now appears—COVID-19. An intriguing new study of these memory T cells suggests they might protect some people newly infected with SARS-CoV-2 by remembering past encounters with other human coronaviruses. This might potentially explain why some people seem to fend off the virus and may be less susceptible to becoming severely ill with COVID-19.
Exploring Drug Repurposing for COVID-19 Treatment
It usually takes more than a decade to develop a safe, effective anti-viral therapy. But, when it comes to coronavirus disease 2019 (COVID-19), we don’t have that kind of time. One way to speed the process may be to put some old drugs to work against this new disease threat. This is generally referred to as “drug repurposing.” NIH has been doing everything possible to encourage screens of existing drugs that have been shown safe for human use. In a recent NIH-funded study in the journal Nature, researchers screened a chemical “library” that contained nearly 12,000 existing drug compounds for their potential activity against SARS-CoV-2, the novel coronavirus that causes COVID-19.
Charting a Rapid Course Toward Better COVID-19 Tests and Treatments
It is becoming apparent that our country is entering a new and troubling phase of the pandemic as SARS-CoV-2, the novel coronavirus that causes COVID-19, continues to spread across many states and reaches into both urban and rural communities. This growing community spread is hard to track because up to 40 percent of infected people seem to have no symptoms. They can pass the virus quickly and unsuspectingly to friends and family members who might be more vulnerable to becoming seriously ill. That’s why we should all be wearing masks when we go out of the house—none of us can be sure we’re not that asymptomatic carrier of the virus.
