Description
Within our current educational infrastructure, there’s a lack of substantial preventive care knowledge present among elementary schoolchildren. With education cuts occurring statewide, many schools are left impoverished and schools are incapable of implementing various programs to benefit their local communities. This endeavor aims to visit public and charter elementary schools

Within our current educational infrastructure, there’s a lack of substantial preventive care knowledge present among elementary schoolchildren. With education cuts occurring statewide, many schools are left impoverished and schools are incapable of implementing various programs to benefit their local communities. This endeavor aims to visit public and charter elementary schools in the Phoenix Valley to educate youth regarding easily avoidable health risks by implementing healthy eating habits and exercise. Project BandAid will immerse students ages 7-9 in hands-on activities to enhance their knowledge on hygiene, healthy eating habits, and safety. This project incorporated funding from the Woodside Community Action Grant and Barrett, the Honors College as well as the help from Alpha Epsilon Delta (AED) volunteers.

Memory CD8+ T cells protect against secondary viral infections. They develop and maintain exclusively in circulation (e.g. central memory - Tcm) or are excluded from re-circulation (resident memory - Trm). The extracellular ATP receptor P2RX7 promotes both Tcm and Trm generation. High (P2RX7hi) P2RX7-expressing early effector cells show survival, memory

Memory CD8+ T cells protect against secondary viral infections. They develop and maintain exclusively in circulation (e.g. central memory - Tcm) or are excluded from re-circulation (resident memory - Trm). The extracellular ATP receptor P2RX7 promotes both Tcm and Trm generation. High (P2RX7hi) P2RX7-expressing early effector cells show survival, memory and pluripotency genes. Conversely, many terminal effector (TE) and apoptosis genes are upregulated in low (P2RX7lo) P2RX7-expressing cells. Among these genes is the zinc-finger transcriptional repressor Zeb2, which promotes TE differentiation at the expense of the memory cell pool. Given that Zeb2 was higher in P2RX7lo early effector cells, we postulated that Zeb2 ablation would allow P2RX7-deficient CD8+ T cells to skew towards memory subsets. To test this, we used RNP-based CRISPR-Cas9 to knockout Zeb2 in wild type or P2RX7-deficient P14 cells. At the memory timepoint, Zeb2 ablation led to a rescue of the ability of P2RX7-deficient cells to differentiate into the CD62L+ Tcm and CD69hiCD103hi Trm subsets, as well as increase the population of each. Our data suggest that P2RX7 imprints a pro-memory signature that is, to some extent, dependent on the negative regulation of Zeb2.
