Are chemotactic cytokines, which stimulate migration of inflammatory cells towards tissue sites of inflammation.
Class of pro-inflammatory cytokines that have the ability to attract and activate leukocytes. They can be divided into at least three structural branches: C (chemokines, C), CC (chemokines, CC), and CXC (chemokines, CXC), according to variations in a shared cysteine motif.
Any polypeptide cytokine that causes chemotaxis, attracting neutrophils, monocytes, and T lymphocytes; e.g., to assist in destroying an invading microorganism.
