New insight into the role of SOCS family in immune regulation and autoimmune pathogenesis

Abstract

Background: Suppressor of cytokine signaling (SOCS) proteins regulate signal transduction by interacting with cytokine receptors and signaling proteins and targeting associated proteins for degradation. Recent studies have demonstrated that the SOCS proteins serve as crucial inhibitors in cytokine signaling networks and play a pivotal role in both innate and adaptive immune responses. Aim of Review: In this review, we aim to discuss recent advancements in understanding the complex functions of SOCS proteins in various immune cells, as well as the effects of SOCS proteins in human health and diseases. Increasing evidence indicates that SOCS proteins are frequently dysregulated in developing autoimmune diseases, suggesting that therapeutic targeting of SOCS proteins could provide clinical benefit. Key Scientific Concepts of Review: This review provides a comprehensive understanding of SOCS proteins in immune regulation and autoimmune pathogenesis, it also highlights the role of SOCS-related mimetic peptides in immunotherapy.
