From The NIH: The Director’s Blog

Dec 2, 2020 | Posted by Industry Expert | Healthcare |

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 to read in entirety.

Can Autoimmune Antibodies Explain Blood Clots in COVID-19?
For people with severe COVID-19, one of the most troubling complications is abnormal blood clotting that puts them at risk of having a debilitating stroke or heart attack. A new study suggests that SARS-CoV-2, the coronavirus that causes COVID-19, doesn’t act alone in causing blood clots. The virus seems to unleash mysterious antibodies that mistakenly attack the body’s own cells to cause clots.

The NIH-supported study, published in Science Translational Medicine, uncovered at least one of these autoimmune antiphospholipid (aPL) antibodies in about half of blood samples taken from 172 patients hospitalized with COVID-19. Those with higher levels of the destructive autoantibodies also had other signs of trouble.

Mini-Lungs in a Lab Dish Mimic Early COVID-19 Infection
Researchers have become skilled at growing an array of miniature human organs in the lab. Such lab-grown “organoids” have been put to work to better understand diabetes, fatty liver disease, color vision, and much more. Now, NIH-funded researchers have applied this remarkable lab tool to produce mini-lungs to study SARS-CoV-2, the coronavirus that causes COVID-19.

The intriguing bubble-like structures (red/clear) in the mini-lung pictured above represent developing alveoli, the tiny air sacs in our lungs, where COVID-19 infections often begin. In this organoid, the air sacs consist of many thousands of cells, all of which arose from a single adult stem cell isolated from tissues found deep within healthy human lungs. When carefully nurtured in lab dishes, those so-called alveolar epithelial type-2 cells (AT2s) begin to multiply. As they grow, they spontaneously assemble into structures that closely resemble alveoli.

Reasons for Gratitude Amid the COVID-19 Pandemic
For many of us, Thanksgiving will feel really different this year. Less will need to be more, as we celebrate alone or with our immediate household members to stay safe and help combat the surge in COVID-19 cases across most of the land. And yet, times of trouble can also help us to focus on what’s really important in our lives. So, even as we face these challenges and the range of emotions that arise with them, it’s worth remembering that this Thanksgiving, there remain many reasons to be grateful.
