Does activation of liver-X-receptor α but not liver-X-receptor β protect against myocardial ischemia/reperfusion injury?
Our study provides the first direct evidence that the LXRα, but not LXRβ, subtype is a novel endogenous cardiac protective receptor against MI/R injury. Drug development strategies specifically targeting LXRα may be beneficial in treating ischemic heart disease.
The new artificial antigen-presenting system including aAPCs plus IL-21 and IL-15 can induce a large number of antigen-specific CD8(+) CD28(+) CTLs against the melanoma. Our study provides evidence for a novel adoptive immunotherapy against tumors.
