Heterogeneity in antigen processing by different types of antigen-presenting cells. Effect of cell culture on antigen processing ability.


The ability of normal B cells, peritoneal macrophages, and splenic APC to process and present OVA to a panel of T-T hybridomas with different specificities was investigated. In all cases, B cells were less efficient than unfractionated splenocytes in presenting OVA or its peptides. However, when the presentation of native Ag was compared to the presentation… (More)
