RESUMO
The major histocompatibility complex class I genes play an essential role in the immune presentation of aberrant cells. To gain further insight into the regulation of the expression of these class I genes and to better define the functions of their protein products, we made use of the technique of gene transfer into the germ line of inbred mice. With the use of locus-specific DNA probes, we observed that a transgenic class I gene was expressed in a tissue-dependent fashion analogous to that of an endogenous class I gene. In addition, the level of expression of the transgenic gene was substantially higher that that of the endogenous gene. The availability of transgenic mice properly expressing a foreign murine class I gene provides a unique system to further define the role of the class I antigens in the maturation of the immune response and in determining the malignant and metastatic phenotypes of tumor cells.
