Differential contribution of Lck and Fyn protein tyrosine kinases to intraepithelial lymphocyte development.

abstract：:Self-glycosphingolipids bind to surface CD1 molecules and are readily displaced by other CD1 ligands. This capacity to exchange antigens at the cell surface is not common to other antigen-presenting molecules and its physiological importance is unclear. Here we show that a large pool of cell-surface CD1a, but not CD1b...
