T cell can only recognize specific antigenic peptide-MHC complex on antigen-presentingcell. This is MHC restriction in antigen recognition of t cell.
细胞只能识别抗原提呈细胞表面特定的抗原肽MHC分子复合物,这就是T细胞抗原识别的MHC限制。
2
They are able to suppress allogenic T-cell response and modify maturation of antigen-presenting cells.
其能够抑制同种异体的T细胞的应答和修饰抗原呈递细胞的成熟。
3
They are found in a perivascular network and may serve as the antigenpresentingcell which initiates immune responses to antigens delivered through the circulation.
