Cellthe Peripheral Activated / Memory CD 4 T Regulatory CD 4 T Cells Control

Persistence of CD 4 T Cell Memory Negatively Regulates

Much is known about the differentiation of naive T cells into distinct lineages of effector cells, but the molecular mechanisms underlying the generation and maintenance of CD4 T cell memory are poorly characterized. Our studies ascribe a novel role for the cell cycle regulator p27 Kip1 as a prominent negative regulator of the establishment and long-term maintenance of Th1 CD4 T cell memory. We...

CD 4 and CD 8 Cell Tests

A wide variety of monitoring tests are available to help gauge HIV disease progression and the state of overall health. HIV viral load tests provide a picture of viral activity, while CD4 cell counts shed light on the status of the immune system and can help physicians predict—and therefore prevent—the development of opportunistic illnesses (OIs).These tests can help guide treatment decisions a...

Accelerated Help to B Cells Memory CD 4 T Cells

CD4 T cell help for B cells is critical for effective Ab responses. Although many of the molecules involved in helper functions of naive CD4 T cells have been characterized, much less is known about the helper capabilities of memory CD4 T cells, an important consideration for the design of vaccines that aim to prime protective memory CD4 T cells. In this study, we demonstrate that memory CD4 T ...
