Expression of CD45 isoforms by fresh and activated human gamma delta T lymphocytes and natural killer cells.

abstract：:Immunoglobulin (IG:) genes are hypermutated in mature B cells after interaction with antigen and T cells in a germinal center reaction. We and others have recently shown that the human BCL6 gene is also hypermutated in human peripheral blood memory B cells and tonsils. A preliminary analysis of other non-Ig genes (c-M...
