Novel Subpopulation of Adipose Tissue Macrophages IMAMs and Their Role in Obesity and Metabolic Disorders Background Obesity is an increasingly severe health issue worldwide, often accompanied by a state of chronic low-grade inflammation. This condition is driven by the infiltration and dysfunction of immune cells within adipose tissue and other me...

Unique Foxp3 Palmitoylation Regulates Tregs Function through Palmitoyltransferases Regulatory T cells (Tregs) play a crucial role in maintaining immune homeostasis and preventing excessive immune responses. As important suppressors of immune reactions, Tregs help maintain immune tolerance, thereby preventing autoimmune diseases. However, in the tum...

Research Report: Neutrophils Disrupt B-1a Cell Homeostasis by Targeting Siglec-G, Exacerbating Sepsis Background Sepsis is a life-threatening organ dysfunction caused by a dysregulated immune response to infection. The immune system dysfunction accompanying sepsis is primarily triggered by pathogen-associated molecular patterns (PAMPs) and damage-a...

Genome-wide screening identifies TRIM33 as an essential regulator of dendritic cell differentiation Background Dendritic cells (DCs) serve as a bridge between innate and adaptive immunity by recognizing pathogens through pattern recognition receptors (such as TLRs) and modulating antigen-specific T cell responses. DCs are mainly divided into two ty...
