immune system
N |
• cells have normal levels of class II expression and the density of H2-Ab-CLIP (class II-associated invariant chain peptides) at the cell surface is the same as in wild-type
|
• older mutants exhibit elevated serum levels of IgG1
|
• B cells have changed capacity to present protein antigens, showing better presentation by mutant B cells after overnight incubation with the antigen, hen egg lysozyme and sperm whale myoglobin, than wild-type cells
