title: Inhibition of class II MHC gene expression by anti-sense RNA in transgenic mice.
abstract: We have established transgenic mice carrying the anti-sense DNA to the gene encoding beta chain of the class II major histocompatibility complex (I-A) molecule. The amount of I-A molecule on splenic B lymphocytes from the mice was reduced in the presence of a large amount of the exogenous anti-sense RNA. The amount of I-A beta chain RNA was selectively reduced and inversely correlated with the amount of anti-sense RNA in the spleens. These results suggest that the I-A beta chain RNA is rapidly degraded by duplex formation with the anti-sense RNA in splenic B cells from the transgenic mice.
