The Invention
UW-Madison researchers have developed methods for preparing PTP1b-deficient neutrophils, which exhibit improved recruitment and antimicrobial functions. The inventors employed CRISPR/Cas9 to delete PTP1b from iPS cells, and then utilized an existing method (P190225) to differentiate the iPSCs into neutrophils. PTP1b-/- neutrophils displayed increased cellular migration and inflammatory cytokine signaling (e.g., IL-6 and TNF) in response to bacterial stimuli, when compared with wildtype cells.
