Title: The cytolytic T lymphocyte response to trinitrophenyl-modified syngeneic cells. I. Evidence for antigen-specific helper T cells. Author: Finberg R, Greene MI, Benacerraf B, Burakoff SJ. Journal: J Immunol; 1979 Sep; 123(3):1205-9. PubMed ID: 89164. Abstract: Mice were primed subcutaneously with trinitrophenyl (TNP)-modified syngeneic spleen cells. Seven days later, spleen cells from these in vivo primed mice, or spleen cells from naive mice, were co-cultured with TNP-modified syngeneic cells. Spleen cells from the in vivo primed mice demonstrated augmented cytolytic T lymphocyte (CTL) activity. The spleens of these in vivo primed mice contained a population of radioresistant, antigen-specific, helper T cells. Specifically, spleen cells from these mice, after x-irradiation, were able to augment the in vitro CTL response of normal spleen cells to TNP-modified syngeneic cells.[Abstract] [Full Text] [Related] [New Search]
