Taurine Attenuates M1 Macrophage Polarization and IL-1β Production by Suppressing the JAK1/2-STAT1 Pathway via Metabolic Reprogramming.

ABSTRACT: Dysregulated macrophage polarization is associated with various diseases, including sepsis, atherosclerosis, and fibrotic diseases. While taurine is known to exert immunomodulatory effects, its mechanism in regulating M1 macrophage polarization and interleukin-1β (IL-1β) production remains incompletely understood. This study aimed to elucidate the role of taurine in modulating macrophage immunometabolism and inflammatory signaling. Using thioglycolate-elicited peritoneal macrophages and macrophage cell lines, we assessed taurine's impact on lipopolysaccharide (LPS)/interferon-γ (IFN-γ)-induced M1 polarization through metabolomics and a range of molecular biology techniques. Pharmacological manipulation of the JAK1/2-STAT1 pathway and an LPS-induced murine sepsis model were used for mechani
