The B6 anti-bm6 allospecific CTL response is strictly dependent on CD4+ cells when using LPS blasts as stimulator cells. Altering the N-linked carbohydrates on stimulator cells by use of the N-linked trimming glycosidase inhibitors 1-deoxymannojirimycin and swainsonine, or by treatment with bacterial neuraminidase, results in a restoration of the B6 anti-bm6 response in the absence of CD4+ cells. The extent of restoration is inversely correlated with the number of sialic acids present on N-linked glycans of stimulator cells.
