Description
Immunosurveillance of secondary lymphoid organs (SLO) is performed by central memory T cells that recirculate through blood. Resident memory T cells (TRM) remain parked in nonlymphoid tissues and often stably express CD69. We recently identified TRM within SLO, and this study addresses knowledge gaps in their origin and phenotype. Parabiosis of dirty mice revealed that CD69 expression is insufficient to infer stable residence. Using selective depletion strategies, parabiosis, imaging, tissue grafting, and photoactivatable T cells, we report that restimulation of TRM within the skin or mucosa results in a substantial increase in TRM that patrol all regions of draining lymph nodes. SLO TRM were derived from nonlymphoid tissue residents. Transcriptional profiling and flow cytometry revealed a refined phenotype shared between both nonlymphoid and SLO TRM. These data demonstrate the nonlymphoid origin of SLO TRM and suggest vaccination strategies by which memory CD8 T cell immunosurveillance can be regionalized to specific lymph nodes.

TAZ-deficient mice have the abnormalities in the lung development. We expect the comparison of the gene expression profiles of TAZ-deficient and wild-type lungs would reveal the underlying mechanisms.

Description
Genetically targeted mice with deficiency for the A2BAR show increased susceptibility to acute myocardial ischemia and are not protected by IP, a powerful strategy for cardioprotection, where short and repeated episodes of ischemia and reperfusion prior to myocardial infarction result in attenuation of infarct size.

Adora2b-elicited Per2 stabilization promotes a HIF-dependent metabolic switch crucial for myocardial adaptation to ischemia.
