Through the establishment of chimeric HLA-DR/I-E transgenes, the authors examined the function of the rheumatoid arthritis (RA) susceptibility alleles HLA-DR1 (DRB1*0101) and DR4 (DRB1*0401) in presenting antigenic peptides derived from the model antigen, type II collagen (CII), and in mediating an autoimmune response.
Through the establishment of a chimeric HLA-DR/I-E transgene, we have examined the function of the rheumatoid arthritis (RA) susceptibility allele HLA-DR4 (DRB1*0401) in presenting antigenic peptides derived from the model Ag, type II collagen (CII), and in mediating an autoimmune response.
In contrast, NC II functions are not sufficient for the induction of neoplasia and are associated with the activation of the WNT and MYC signaling pathways in keratinocytes and a more general resistance to the induction of apoptosis by a variety of stimuli.
Involvement of GTA protein NC2beta in neuroblastoma pathogenesis suggests that it physiologically participates in the regulation of cell proliferation.
