The activation and differentiation of T cells require three signals: antigen presentation, costimulation, and cytokine stimulation. APCs are required for T cell activation. They can process and present antigens to T cells in the form of antigen peptide:MHC molecular complexes, which are recognized by … See more Adaptive immunity is characterized by specificity, immunological memory, and self/nonself recognition (1). The function of the adaptive immune system is to recognize, remember and destroy invading pathogens through … See more Similar to T cell activation and differentiation, B cell activation and differentiation also requires three signals.

WebFeb 23, 2016 · Lipid-free fibroblast-like cells, known as dedifferentiated fat (DFAT) cells, can be generated from mature adipocytes with a large single lipid droplet. DFAT cells can re-establish their active proliferation ability and can transdifferentiate into various cell types under appropriate culture conditions. The first objective of this study was to ... WebMar 12, 2013 · Further experiments in mouse cells showed that activation of T cells in adipocytes is mediated by MHC class II molecules and is antigen-dependent. Finally, … WebLeptin secreted by adipocytes stimulates IFN-γ production from CD4 + T cells, which further promotes adipocyte MHCII expression and antigen-presentation to induce Th1 cell differentiation, leading to a vicious cycle of AT inflammation.
