| abstractText | CD2 is a T cell surface glycoprotein that mediates cellular adhesion and can participate in signal transduction. It is expressed early in thymocyte ontogeny and consequently has been proposed to participate in T cell development. To study the in vivo function of CD2, the murine gene was inactivated using the technique of homologous recombination in embryonic stem cells. Homozygous mutant mice are healthy and have an apparently normal complement of lymphocytes. They mount effective immune responses similar to those of wild type controls. In particular, the generation and function of cytotoxic T cells was found to be normal as was the production of antibodies following immunization. Selection of thymocytes expressing either MHC class I- or class II-restricted transgenic T cell receptors was also grossly normal in the absence of CD2. Thus, CD2 may be dispensable for the development and function of T cells. Within the context of other targetted mutations, these mice should be useful in defining the precise roles of various cell surface molecules involved in T cell responses. |
