COVID-19

"Early reports have demonstrated severely elevated levels of inflammatory biomarkers and cytokines, including IL-6, C-reactive
protein (CRP), tumor necrosis factor (TNF)-α, interleukin (IL)-2R and ferritin (112)."

Fluoride

Fluoride has long been known to influence TNF activity in various organs of animals and humans (Lu et al., 2017; Sana et al., 2017; Afolabi et al., 2013; Guo et al., 2017).

"... interleukin 2 (IL-2) increased more than 1.5-fold (p<0.05) and IL-6 and plasma TNF-α more than 2.5 fold (p<0.05)."

Gq/11

ALSO: Gq/11 activates MAPK, which in turn regulates TNF-alpha.

"Among the MAPKs, p38 MAPK regulates the expression of tumor necrosis factor- (TNF-) α, interferon- (IFN-) γ, and other cytokines via transcriptional and posttranscriptional mechanisms...Solid evidence has supported that endothelin-dependent ERK/MAPK activation depends on the GqPCR/PLC-β/Ca2+/Src signaling cascade [64]. Taken together, these studies have shown that GqPCR and Gαq are involved in the activation of ERK."

(Zhang & Shi, 2016)

"Moreover, IL-17A and TNF-α in PSO patients were negatively associated with the Gαq expression."
