Acidification of internalized class I major histocompatibility complex antigen by T lymphoblasts
1984
Abstract It has previously been shown that activated murine T lymphocytes express intracellular vesicles containing the class I major histocompatibility complex (MHC) antigen H-2K. Evidence has also been provided that such vesicles may be part of a cellular pathway of spontaneous H-2K antigen internalization and recycling, which is specific to T-lymphoid cells. Dual fluorescence flow cytometry has now been used to establish that H-2K antigen is acidified upon internalization in concanavalin A-stimulated but not lipopolysaccharide-stimulated murine splenocytes, thus providing further support that in T lymphoblasts this class I MHC antigen may travel intracellular routes similar to those reported for other cell surface receptors.
