Neuronal cells from murine trisomy 16 fetuses have increased levels of class I MHC H-2Kk. To determine whether this increased level of H-2Kk protein product resulted from an increased synthesis of mRNA, a 33 base antisense cDNA probe complementary to a region in exon 2 of the H-2Kk sequence (nucleotide 392-424) was synthesized. This probe was used to examine, by in situ hybridization and immunohistochemistry, the neural distribution of H-2Kk mRNA and protein product. A marked elevation of the H-2Kk mRNA and protein were localized in mts16 neuronal populations that were susceptible to dysgenesis. The results implicate the expression of the H-2Kk in the neuropathology of mts16 and its human counterpart, Down syndrome.
