Most neural cells constitutively lack major histocompatibility complex (MHC) class I and beta 2-microglobulin gene expression. Cytokines and viruses may, however, induce expression of these genes in some neural cells, and this correlates with factor binding to the NF-kappa B and interferon stimulated response elements of these genes. Here, we demonstrate that NF-kappa B is capable of inducing MHC class I and beta 2-microglobulin gene expression when transiently co-transfected into CHP-126 neuroblastomas, and that IRF-2 represses this induction. Interferon regulatory factor-2 (IRF-2) repression of MHC class I and beta 2-microglobulin gene expression in CHP-126 neuroblastomas may demonstrate a mechanism by which virus persists in neural cells. We show here that IRF-2 physically interacts in vitro with NF-kappa B. This interaction may contribute to the repression of the expression of these genes. Our demonstration that IRF family members, in addition to IRF-2, physically interact in vitro with NF-kappa B (p50 and p65), provides a general mechanism by which these transcription factors may, in concert, regulate the expression of a variety of genes involved in immune responses in the brain.
