Furthermore, statins are well-known modulators of the adaptive immune system through their effect on lymphocytes and antigen-presenting cells [19,20]: they promote Th2 responses leading to the increased production of anti-inflammatory cytokines (IL-4, IL-5, and IL-10) [21] and inhibit IL-12-dependent Th1 cell differentiation and the production of pro-inflammatory cytokines IL-2, IL-12, IFN-γ, and TNF-α [22], which are believed to play an important role in the pathogenesis of COVID-19. Here, TNF is linked to COVID-19.
