| abstractText | The New Zealand white (NZW) H2(z) locus is strongly associated with the development of autoimmune disease in (NZB x NZW)F(1) mice, a model of systemic lupus erythematosus. To better understand the role of H2(z) in autoimmunity, we generated CD4(+) T cell hybridomas from the spleen and lymph nodes of unimmunized (NZB x NZW)F(1) mice and characterized their specificity. We found that over 50% of the hybridomas responded to syngeneic (H2(d/z)) spleen cells in the absence of exogenous antigen. Many of these autoreactive hybridomas responded to spleen cells expressing H2(z) and used H2(z) class II (I-A(z) or I-E(z)) molecules for presentation. Interestingly, nearly one third of the H2(z)-reactive hybridomas could not respond to spleen cells expressing only H2(z) class II molecules. These studies characterize a frequent population of autoreactive CD4(+) T cells in lupus mice and indicate that major histocompatibility complex molecules in addition to class II may be important for this self-recognition. |
