Coligation of either LIR with Fc纬 receptor I (CD64) inhibits tyrosine phosphorylation of the associated Fc receptor 纬 chain and Syk molecules, as well as intracellular calcium mobilization. These findings suggest that LIR-1 and LIR-2 function as unique MHC class I receptors involved...

it is poorly understood whether and how post-translational modifications (PTMs) intrinsically affect the phenotype and function of TAMs. Here, we reveal that peptidylarginine deiminase 4 (PAD4) exhibits the highest expression among common PTM enzymes in TAMs and negatively correlates with the clinical...
325 Accesses 1 Citations Abstract Immunological recognition of transplanted tissues is not a requisite function selected evolutionarily, but rather reflects the robust capacity developed by the innate and adaptive immune systems to counter infection and neoplasia. The rejection of genetically disparate grafts...
A synthetic cytotoxic T cell platform for rapidly prototyping TCR function Article Open access 19 August 2024 References Xiong, Y., Kern, P., Chang, H. & Reinherz, E. T cell receptor binding to a pMHCII ligand is dinetically distinct from and independent of CD4. J. Biol. Chem. 27...
The function of the APCs is to present a peptide derived from the antigen to the T cell. 2、抗原递呈细胞 抗原提呈细胞(antigen-presenting cell,APC)是指能表达被特异淋巴细胞识别的抗原肽:MHC分子复合物的任何细胞(图2-8,图2-9)。 (1)专职抗原提呈细胞:能表达MHC-II类分子的巨噬细胞、树突状细胞...
growing and reproducing inside the cells of their hosts. In 1989, the first structure of the MHC class I molecule was published named human HLA-A2. The main function of the class I MHC is to present the proteins that lie inside the cell to cytotoxic T cells which are also called ( CTL...
What is the difference between MHC 1 and MHC 2? MHC genes are expressed to produce surface antigens on the cell membrane. ... The main difference between MHC class 1 and 2 is thatMHC class 1 molecules present antigens to cytotoxic T cells with CD8+ receptorswhereas MHC class 2 molecules...
TheMHCclass II molecules are cell-surfaceglycoproteins, which bind peptides of extracellular origin, and display them to CD4+T cells.36TheMHC class IImolecules consist of two noncovalently-associatedpolypeptidechains, the α andβ chains, which comprise two extracellular domains, α1 and α2, or...
doi:10.4161/self.2.1.15757Half a century after the major histocompatibility complex (MHC) was discovered, its functional roles in health and disease remain poorly understood. Many hallmarks of the MHC, including its unusual evolution, structure-function properties of its gene products, and allele-...
