Abstract:
The primary transcript of the human CD28 gene in T lymphocytes, encoding for a costimulatory molecule, is known to undergo alternative splicing, and different small sets of variant isoforms have been reported. This report presents the novel simultaneous presence of eight different mRNA isoforms, all observed together in normal human T cells; this is an interesting finding in the study of CD28 mRNA structural variants. A similar pattern was found in a total of four individuals. In addition, we also report the occurence and sequence of a new CD28 mRNA isoform, one of the above eight, which is a novel variant generated by the use of a new combination of splice donor and acceptor sites.

Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
