T Cell-Intrinsic and Extrinsic Mechanisms of p27Kip1 in the Regulation of CD8 T Cell Memory

CD8 T cells exhibit dynamic alterations in proliferation and apoptosis during various phases of the CD8 T-cell response, but the mechanisms that regulate cellular proliferation from the standpoint of CD8 T-cell memory are not well defined. The cyclin-dependent kinase inhibitor p27(Kip1) functions as a negative regulator of the cell cycle in T cells, and it has been implicated in regulating cell...

The Study of Memory Remembering

Memory CD8+ T cell responses expand when antigen presentation overcomes T cell self-regulation.

Antimicrobial memory CD8+ T cell responses are not readily expanded by either repeated infections or immunizations. This is a major obstacle to the development of T cell vaccines. Prime-boost immunization with heterologous microbes sharing the same CD8+ epitope can induce a large expansion of the CD8+ response; however, different vectors vary greatly in their ability to boost for reasons that a...

Down-Regulation of T Cell Function by Heat Shock-Induced Excretory Factor of Leishmania Major

Background: Despite demonstration of molecular and biochemical changes induced by heat shock on Leishmania, the immunological importance of such changes has not been elucidated.  Objective: Studying the effect of two excretory factors prepared under heat shock and ambient temperature from Leishmania major on Balb/c splenocytes function.  Methods: The parasites were cultured at 25°C and then sub...
