Upon adoptive transfer into histocompatible mice, naive CD8(+) T cells stimulated ex vivo by TCR+IL-4 turn into long-lived functional memory cells. The liver contains a large number of so formed memory CD8(+) T cells, referred to as liver memory T cells (T(lm)) in the form of cell clusters. The CD62L(low) expression and nonlymphoid tissue distribution of(More)
Inflammatory bowel disease is a chronic and progressive inflammatory intestinal disease that includes two major types, namely ulcerative colitis and Crohn's disease (CD). CD is characterized by intestinal epithelial hyperplasia and inflammatory cell infiltration. Transfer of CD25(-)CD45RB(hi)CD4(+) (naïve) T cells into immunodeficiency mice induces(More)
Emerging evidences have shown that diabetes mellitus not only raises risk but also heightens mortality rate of cancer. It is not clear, however, whether antitumor CD8+ cytotoxic T lymphocyte (CTL) response is down-modulated in diabetic hosts. We investigated the impact of hyperglycemia on CTLs' acquisition of tumor-killing capability by utilizing(More)
