摘要：We have generated a transgenic mouse line in which a CD4 transgene is expressed on a significant fraction of the mature CD8+ lymphocytes but is not expressed in the thymus. This provides an opportunity to examine the functional consequences of CD4 expression in a population of class I-selected CD8+ lymphocytes. CD8+ lymphocytes expressing the CD4 transgene proliferate in response to allogeneic class I and class II major histocompatibility complex, whereas CD8+ cells from control animals proliferate only to allogeneic class I gene products. These observations suggest that the ability of a T-cell population to react with class II allogeneic major histocompatibility complex is determined by the presence of CD4.
