CXCR2 (C-X-C Motif Chemokine Receptor 2) is a receptor that binds C-X-C motif chemokines, such as CXCL5, and is primarily found on neutrophils. It plays a crucial role in guiding neutrophil movement and activation during inflammation. CXCR2 is involved in various pathological conditions, including inflammatory diseases, cancer, and chronic obstructive pulmonary disease (COPD), making it a key target for therapeutic interventions.
