of the placebo patients in a year long, chemopreventive toremifene study, which was also presented at the AACR meeting here, confirmed that men with high-grade PIN have an increased, cumulative risk of being diagnosed with prostate cancer after one y...
Lag-3 gene dampens immune responses by controlling regulatory T-cell function
... Next, the team used a technique called DNA array analysis
to identify which genes in the CD4+ T cells are activated in cells that develop into regulatory T cells. The investigators found that the Lag-3 gene was "expressed" (being used by the cell to make protein) to a much greater extent in regulatory T cel...
