CXCL2 (also known as macrophage inflammatory protein, MIP-2) is part of one chemokine superfamily encoding secreted proteins that are involved into inflammatory and immunoregulatory process, and released by various cells to respond toward injury or infection, and was detected originally within the macrophages to one part of the responses toward the inflammatory stimuli (Charo and Ransohoff, 2006). This evidence concerns the gene CXCL2 and infection.
