Some examples of chemokines, including molecules such as CXCL8 (also known as interleukin-8), CCL2 (also known as monocyte chemoattractant protein-1), and CXCL10 (also known as interferon gamma-induced protein 10) facilitate the recruitment and activation of various immune cells, enabling an efficient immune response to combat the infection. The gene discussed is CCL2; the disease is infection.
