Insights into the itaconate family: Immunomodulatory mechanisms and therapeutic potentials.

The itaconate family, comprising itaconate derivatives, endogenous isomers, and other related compounds, has demonstrated substantial immunoregulatory properties. These compounds exhibit significant therapeutic potential in various disease models by modulating metabolic pathways, signal transduction cascades, and post-translational modifications. In this review, we delineate the structural characteristics and biological functions of the members of the itaconate family and elucidate their immunomodulatory mechanisms. Additionally, we summarize the immunomodulatory effects of the itaconate family across various disease categories, including cardiovascular, liver, respiratory, bone and cartilage, neurological, and autoimmune diseases. This review aims to deepen our understanding of the itaconate family and its potential applications, providing new perspectives and therapeutic strategies for inflammatory disorders and autoimmune diseases.
