“Must read article again documenting how important it is to have optimal Vit D3 levels and how this is necessary for T-cells to do their jobs. It also mentions that Dr. Fauci takes 6000 IU a day! Have you ever heard him suggest that the American people do that … neither have I. The article is a little bit technical in the beginning but not that bad.” Admin
Thank you to Dr. Doshi for raising the profile of T-cells. Incidentally, German researchers found that a staggering 81% of individuals had pre-existing T-cells that cross-react with SARS-CoV-2 epitopes. This fits with modelling in May by Imperial College’s Professor Friston, a world authority in mathematical modelling of complex dynamic biological systems, indicating that around 80% and 50% of the German and UK populations, respectively, are resistant to COVID-19.
Antibodies can only latch onto and help destroy pathogens outside cells and may also occasionally, paradoxically, enhance a pathogen’s ability to infect cell instead by antibody dependent “enhancement” or ADE. It is only the T-cell that can cleverly sense and destroy pathogens inside infected cells using “sensors” which detect foreign protein fragments.
In the late 60’s, the Lancet described a case of a child with agammaglobulinemia, a condition in which absence of B cells prevent them from producing antibodies, who overcame a measles infection quite normally and did not become re-infected thereafter. We now know that, although this condition can compromise immunity, in that particular case the rest of the immune functions, including T-cells, must have been perfectly up to the job of clearing infection and establishing immune memory without help from antibodies. The importance of T-cells in fighting SARS-CoV-1 and establishing immune memory has also been well documented and discussed in a number of pre-COVID papers from 2017 and earlier.
