Specific B lymphocytes can act as very efficient antigen-presenting cells. They bind antigen with high affinity via their immunoglobulin receptors, process it through the class II major histocompatibility complex (MHC) pathway, and present its fragments to class II-restricted T lymphocytes. In general, exogenous antigens and noninfectious viral particles(More)
Human activated T lymphocytes expressing class II molecules are able to present only complex antigens that bind to their own surface receptors, and thus can be captured, internalized, and processed through the class II major histocompatibility complex processing pathway. We have used the antigen-presenting T cell system to identify the viral receptor used(More)
T cell clones derived from the cerebrospinal fluid of patients with multiple sclerosis were investigated for their ability to produce IL2, IL4, IFN gamma and TNF alpha. As controls, liver infiltrating T lymphocyte clones from patients with chronic active hepatitis were used. All CSF clones (both CD4+ and CD8+) produced high amounts of IFN gamma and(More)
