Understanding the response of memory CD8 T cells to persistent antigen re-stimulation and the role of CD4 T cell help is critical to the design of successful vaccines for chronic diseases. However, studies comparing the protective abilities and qualities of memory and naïve cells have been mostly pe...

We recently showed that the Slamf6 protein isoform Slamf6-H1 markedly diminishes T cell–dependent disease upon introduction of a Slamf6-H1–expressing transgene into the lupus-prone Sle1b mouse, which lacks this isoform. In this study we purified CD4+ T cells from Sle1b, Sle1b.Slamf6-H1, or B6 mice a...

This work shows that signaling-lymphocytic-activation-molecule-1 (SLAMF1), a co-stimulatory molecule and a microbial sensor, is expressed by normal CD19+/CD5+ B-lymphocytes. Its expression is lost in a subset of patients with chronic lymphocytic leukemia (CLL) characterized by an aggressive form of ...
