"In addition to its direct antiviral activity, CQ and HCQ can attenuate major "cytokine storms" (an overreaction of the immune system causing inflammatory "storms") by decreasing cytokine production (interleukin [IL]-1, IL-6, and tumor necrosis factor[TNF], etc.) ( Fig. 3 ) (van den Borne et al., 1997) ."

"In a randomised, double-blinded, placebo-controlled clinical trial of 40 asymptomatic patients with HIV-1, 800 mg/d hydroxychloroquine treatment for 8 weeks reduced the plasma concentration of HIV-1 RNA, preserved CD4+ T-cell counts and proliferative responses, and lowered serum IL-6 concentrations, compared with the placebo group.63 Although it takes 1–3 months for hydroxychloroquine and chloroquine to fully take effect in patients with rheumatic disease, the drugs' anti-viral effect is relatively rapid."

reach
"On the other hand, the immune-modulating effect of HCQ is represented in inhibition of signaling of the toll-like receptor and reducing the production of IL-1 and IL-6 [5]."

"This suggests that the preferential decrease of IL-6 production by HCQ may by mediated by its ability to decrease miR-21 expression."

"Hydroxychloroquine reversed the aPL-inhibition of trophoblast IL-6 secretion and partially limited aPL-inhibition of cell migration."
