NK cell development, maturation, and activation by cytokines is driven by alterations in gene expression mediated by activation and repression or transcriptional programs. In particular, we have extensively studied the role of STAT3 in human NK cells. This was based in part on a method we developed for in vitro expansion of large numbers of highly active NK cells using a genetically-modified feeder cell expressing 4-1BBL and membrane-bound IL-21. To dissect the various gene expression profiles induced by IL-21 from the various other signals received from the feeder cell, we purified peripheral NK cells from 4 healthy subjects (nave, N), expanded NK cells for 14 days using CSTX002 feeder cells (expanded, E), and extracted RNA from the cells without (Neg) or after (Pos) the cells were activated with IL-21. We then performed RNA sequencing on each sample. SOURCE: Dean Lee (Dean.Lee@nationwidechildrens.org) - Nationwide Children’s Hospital
