Effects of cyclosporine A on thymocyte differentiation in fetal thymus organ culture.

abstract：:Within the lymphoid compartment, CD8 is expressed either as an alphaalpha homodimer or as an alphabeta heterodimer. Prior functional characterization of CD8alpha transfectants has demonstrated that CD8alphaalpha homodimers can reconstitute T cell responses in the absence of the CD8beta subunit. In order to now examine...
