The calcineurin-NFAT axis contributes to host defense during Pseudomonas aeruginosa lung infection.

abstract：:In inflammatory diseases, circulating neutrophils are recruited to sites of injury. Attractant signals are provided by many different chemotactic molecules, such that blockade of one may not prevent neutrophil recruitment effectively. The Slit family of secreted proteins and their transmembrane receptor, Robo, repel a...
