"However, higher concentrations of HCQ (3 mM) tended to inhibit OB differentiation (Fig. 1C), and this inhibition was attenuated by the combination of HCQ and HABP (Fig. 1C) because the HABP also slightly promoted OB differentiation from the BM stromal cells (Fig. 1D)."

"In experiments with rodents and PBMC isolated from SLE and HIV patients, HCQ attenuated Th17 differentiation, proliferation, and production of IL-17 while promoting the immunosuppressive effect of Tregs (Piconi et al., 2011; An et al., 2017; Yang et al., 2018; Kowatsch et al., 2023)."

"As the majority of previous studies focused on the innate immunity, only a few in vitro studies showed that HCQ could reduce the activation, proliferation and differentiation of T cells (11–13)."

"Furthermore, Yang et al. found that HCQ reduced the differentiation of Th17 cells and the production of IL-17A in vitro using PBMCs from SLE patients (13)."

"Hydroxychloroquine therapy may also reduce B cell activity [129] and Th17 cell differentiation [130,131], while promoting a Th1 to Th2 transition [130] and inhibiting the production of the PICs CCL2 and CXCL10 [132]."

"In high-fat diet-induced obese mice, HCQ decreased the hepatic levels of macrophage-specific genes [cluster of differentiation 68 (CD68) and arginase 1 (Arg1)] and pro-inflammatory genes (IL-1β, TNF-α and MCP-1)."
