Egyptian Rousette Bat (Rousettus aegyptiacus) CXCL1 (C-X-C motif chemokine ligand 1), also known as GRO-α (growth-regulated oncogene alpha), is a proinflammatory chemokine belonging to the CXC chemokine family, which includes related chemokines such as CXCL2, CXCL3, and CXCL8 (IL-8) that regulate neutrophil recruitment during inflammatory responses. In Egyptian Rousette bats, CXCL1 is produced by macrophages, epithelial cells, endothelial cells, and other immune or tissue cells in response to infection, inflammatory cytokines, or tissue injury. CXCL1 exerts its biological effects primarily through binding to the chemokine receptor CXCR2, promoting chemotaxis and activation of neutrophils and other innate immune cells at sites of infection or inflammation. Egyptian Rousette bats are natural reservoirs for several viruses, including Marburg virus, and chemokines such as CXCL1 likely contribute to early innate immune responses and recruitment of neutrophils to infected tissues while helping coordinate broader immune signaling. Characterization of Egyptian Rousette Bat CXCL1 therefore supports research on bat immunology, host–pathogen interactions, and mechanisms that allow bats to control viral infections with limited inflammatory pathology, providing insights relevant to zoonotic disease biology and immune regulation.
