Naive t cell vs effector t cell
Witryna17 sty 2024 · Effector T lymphocytes interact with host cells (rather than the pathogen) to carry out their immune function. T lymphocytes use co-receptors to bind to the MHC molecules. Co-receptors can be either CD4 or CD8. CD proteins help to differentiate major groups of effector T lymphocytes. Naïve CD8+ T lymphocytes will become … WitrynaThe patients with RH presented higher frequencies of CD4+ effector memory T cells (T EM) (36 ± 16% vs. 21 ± 8.3%, p < 0.01) and CD4+ effector memory residential cells (T EMRA) than the control ... It should be noted that the significantly higher level of CD4+ naïve T cells in the non-responders in our cohort was also higher than the level ...
