The presentation of antigenic peptides by major histocompatibility complex (MHC) class I and class II molecules is crucial for activation of the adaptive immune system. The nucleotide-binding domain and leucine-rich repeat receptor family members CIITA and NLRC5 function as the major transcriptional activators of MHC class II and class I gene expression, respectively. Since the identification of NLRC5 as the master regulator of MHC class I and class-I-related genes, there have been major advances in understanding the function of NLRC5 in infectious diseases and cancer. Here, we discuss the biological significance and mechanism of NLRC5-dependent MHC class I expression.
主要组织相容性复合体 (MHC) Ⅰ类和Ⅱ类分子呈递抗原肽对于适应性免疫系统的激活至关重要。核苷酸结合域和富含亮氨酸重复受体家族成员 CIITA 和 NLRC5 分别作为 MHC Ⅱ类和Ⅰ类基因表达的主要转录激活因子发挥作用。自从 NLRC5 被鉴定为 MHC Ⅰ类和Ⅰ类相关基因的主调控因子以来,人们对 NLRC5 在传染病和癌症中的功能有了更深入的了解。在这里,我们讨论了 NLRC5 依赖性 MHC Ⅰ类表达的生物学意义和机制。
