"CD4+ T, CD8+ T, IL-6, IL-10 and PII can be used as indicators of disease evolution, and the PII can be used as an independent indicator for disease progression of COVID-19."

Wan S, Yi Q, Fan S, Lv J, Zhang X, Guo L, Lang C, Xiao Q, Xiao K, Yi Z, Qiang M, Xiang J, Zhang B, Chen Y, Gao C - "Relationships among lymphocyte subsets, cytokines, and the pulmonary inflammation index in coronavirus (COVID-19) infected patients" Br J Haematol 189(3):428-437 (2020) doi: 10.1111/bjh.16659. Epub 2020 Apr 20. PMID: 32297671.


Depending on dose and tissue, fluoride may cause decreased or increased IL-10 levels.

Luo Q, Cui H, Deng H, Kuang P, Liu H, Lu Y, Fang J, Zuo Z, Deng J, Li Y, Wang X, Zhao L - " Sodium fluoride induces renal inflammatory responses by activating NF-κB signaling pathway and reducing anti-inflammatory cytokine expression in mice" Oncotarget 8(46):80192-80207 (2017) doi: 10.18632/oncotarget.19006. PMID: 29113295; PMCID: PMC5655190.

"Thus, protein expression levels of IL-2, TNF-α, IFN-γ, TGF-β were decreased (P<0.05 or P<0.01), and IL-10 protein expression levels were increased (P<0.05 or P<0.01)."

"These data suggest that pro- versus anti-inflammatory effects of AhR may be partially regulated by Gq/11 receptors including GPR68. We speculate this pathway may regulate inflammation in peripheral tissues with extracellular acidification."

"There was a significant decrease in TSH over time (P < 0.0001), (initial levels were on average 32.4 μIU/mL and 10.5 μIU/mL at 12 months). There was a significant increase in FT4 (P < 0.0001) (initial levels were on average 0,8 ng/dL and 2.7 ng/dL at 12 months). There were significant changes in interleukin levels over time, with a significant increase in IL-10 (P < 0.0001) and significant decreases in IL-1 (P < 0.0001), IL-6 (P < 0.0001), INF-γ (P < 0.0001) and TNF-α (P < 0.0001)."

Marchiori RC, Pereira LA, Naujorks AA, Rovaris DL, Meinerz DF, Duarte MM, Rocha JB - "Improvement of blood inflammatory marker levels in patients with hypothyroidism under levothyroxine treatment" BMC Endocr Disord 15:32 (2015) doi: 10.1186/s12902-015-0032-3. PMID: 26100072; PMCID: PMC4476077.

Fluoride is a TSH agonist - compare Marchiori et al., to Kuang et al., above.
