KXLY April 3, 2021 5:07 PM Matthew Kincanon Updated: Scanning electron micrograph of a human T cell from the immune system of a healthy donor. NIAID ROCKVILLE, Md. Despite concerns regarding COVID variants, researchers at the National Institute of Allergy and Infectious Disease found an active T cell in blood samples of 30 people who had previously contracted and recovered from the virus before the variants emerged. When SARS-CoV-2 (the virus that causes COVID-19) variants surfaced in late 2020, concerns arose that they would elude protection from prior infections or vaccines, potentially making reinfection more likely or vaccines less effective. However, researchers found one T cell, CD8+, that remained active against the virus. ....
Covid-19 Update Recent research throws light on the significance of the role T-cells play in immune response against the coronavirus Print edition : April 23, 2021 T+ T- A scanning electron micrograph of a human T lymphocyte (also called as a T-cell) from the immune system of a healthy donor. Cellular immunity is mediated by T-cells, which tailor the immune response to a specific pathogen, say a virus.

T Cells Fighting COVID-19 Infection Also Protect Against New Variants 01/04/2021 A graffiti depicting the Statue of Liberty wearing a mask on a street in Mumbai. Photo: Reuters/Francis Mascarenhas Chicago: A critical component of the immune system known as T cells that respond to fight infection from the original version of the novel coronavirus appear to also protect against three of the most concerning new virus variants, according to a U.S. laboratory study released on Tuesday. Several recent studies have shown that certain variants of the novel coronavirus can undermine immune protection from antibodies and vaccines. But antibodies – which block the coronavirus from attaching to human cells – may not tell the whole story, according to the study by researchers at the National Institute of Allergy and Infectious Diseases (NIAID). T cells appear to play an important additionally protective role. ....
