Phenotypic and functional heterogeneity of the IgD- B cell compartment: identification of two major tonsillar B cell subsets.

abstract：:Three MHC class II-derived synthetic peptides (I-A beta (g7)1-16, I-A beta (g7)52-77 and I-A alpha (g7)63-82YC) were analyzed for their ability to bind to syngeneic and allogeneic MHC class II molecules using a whole cell, competitive peptide binding assay. These studies demonstrated that the A beta (g7)1-16 peptide w...
