Acute inflammatory responses are important in host defense, whereas dysregulated inflammation results in life-threatening complications. Here we found that paired immunoglobulin-like type 2 receptor alpha (PILRα), an inhibitory receptor containing immunoreceptor tyrosine-based inhibitory motifs (ITIMs), negatively regulated neutrophil infiltration during
