Interleukin-10 is the primary anti-inflammatory cytokine, produced by Treg cells, macrophages, dendritic cells, and B cells. It suppresses pro-inflammatory cytokine production (IL-6, TNF-alpha, IL-1β), inhibits antigen presentation, and maintains immune tolerance.
IL-10 deficiency or dysfunction is the immunological substrate of chronic inflammatory disease—IL-10 knockout mice develop spontaneous colitis, making it the foundational model for IBD research.

COVID-19: IL-10 elevation relative to IL-6 (e.g., via Dialister enrichment) may support recovery; restoring IL-10:IL-6 ratio is a therapeutic target.
ASD: IL-10 paradoxically elevated (9.64 vs. 6.04 pg/ml) alongside pro-inflammatory cytokines, suggesting compensatory anti-inflammatory response.
Endometriosis: IL-10 elevated in peritoneal fluid (compensatory to TNF-alpha/IL-6 excess).
Schizophrenia: Reduced IL-10 contributes to Th17/Treg imbalance.
Microbiome Connection#
SCFA-driven IL-10: Butyrate from gut commensals promotes Treg differentiation → IL-10 production. Dysbiosis-driven butyrate loss reduces IL-10, shifting the Th17/Treg Balance toward Metal-Driven Inflammation.
