As a novel marker of heart failure, sST2 has attracted much attention in recent years. It can reflect the degree of myocardial fibrosis and predict whether ventricular remodeling will occur. It is worth noting that sST2 is not affected by age, gender and renal function and other factors. Also, with low reference change values and individuality index values, sST2 seems to be the best candidate for monitoring and guided therapy. In short, sST2 is one of the ideal indicators to evaluate heart failure. This review summarizes the research progress of sST2 in the diagnosis and prognosis of heart failure in recent years, and provides perspectives for its future development.Toll like receptors (TLRs) are pattern recognition receptors and represent immune receptors in innate immunity. They are very conservative in evolution and extremely important for the survival of organisms. TLRs initiate signal transduction through binding of endogenous or exogenous ligands to activate a series of downstream important gene expression and activation. Studies have shown that regulatory T cells (Tregs) play a central role in maintaining peripheral immune tolerance and preventing transplant rejection. Tregs express certain TLRs, including TLR2, TLR4, TLR5, TLR7, TLR8, and TLR9. Activation of TLRs may directly or indirectly affect (mainly activate) Treg proliferation and immunosuppressive functions, and this regulation is closely related to the occurrence of infection, autoimmune disease and cancer. The heat shock proteins as TLRs ligand molecules play important roles in the regulation of Treg. Therefore, understanding regulatory mechanisms of TLR pathways on Tregs is of great significance for new drug development and targeted therapy. This review i
