HLA-DRB1*0401 expression in humans has been associated with a predisposition to
developing rheumatoid arthritis (RA) and collagen-induced arthritis (CIA), while
HLA-DRB1*0402 is not associated with susceptibility. Here, we determined if mice
transgenic (Tg) for human *0401 have a CD4+ T-cell repertoire that predetermines
proinflammatory cytokine production. The data show that both *0401 and *0402 Tg
mice can produce TH1/TH17 cytokines, although the kinetics of response may be
different. However, in the context of antigen-specific responses in a CIA model,
*0402 Tg mice generate a TH2 response that may explain their resistance to
developing arthritis. In addition, a significant subset of naïve CD4+ T cells
from *0402 Tg mice can be activated in polarizing conditions to differentiate
into Treg cells that produce IFN-?. *0401 Tg mice harbor memory CD4+ T cells that
differentiate into IL-17(+) cells in various polarizing conditions. Our data
suggest that *0401 Tg mice generate a strong immune response to
lipopolysaccharide and may be efficient in clearing infection, and may *0401 have
been evolutionarily selected for this ability. Autoimmunity, such as RA, could
likely be a bystander effect of the cytokine storm that, along with the presence
of low Treg-cell numbers in *0401 Tg mice, causes immune dysregulation.
