Immune T Cells May Offer Lasting Protection Against COVID-19
Immune T Cells May Offer Lasting Protection Against COVID-19Posted on July 28th, 2020 by Dr. Francis CollinsCaption: Scanning electron micrograph of a human T lymphocyte (T cell) from a healthy donor’s immune system. 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. They focused their attention on T cells (including CD4 helper and CD8 cytotoxic, both of which can function as memory T cells). The team found that all those recently recovered from COVID-19 produced T cells that recognize multiple parts of SARS-CoV-2. Their studies showed that those individuals still had lasting memory T cells today, 17 years after the outbreak.
