title: Production of tumour necrosis factors by human T cells stimulated by a superantigen, toxic shock syndrome toxin-1.
abstract: The capacity of human T cell subsets, CD4+ or CD8+ T cells, to produce tumour necrosis factors (TNF-alpha and TNF-beta) upon stimulation with toxic shock syndrome toxin-1 (TSST-1) and the requirement for MHC class II molecules on accessory cells (AC) in the response were investigated. The capacity of CD4+ T cells was much higher than that of CD8+ T cells in TSST-1-induced production of TNF-alpha and TNF-beta. The expression of MHC class II molecules on AC was required in the response.
