chemokines

Chemotactic CYTOKINES, a family of about 50 structurally-related heparin-binding proteins that can induce activation and migration of specific types of white cell, attracting them to sites of inflammation by chemotaxis. They have a fundamental role in inflammation and are concerned in the immune system protective responses to infecting organisms. Chemokines are also concerned in ANGIOGENESIS. Chemokines are implicated in allergic rhinitis, rheumatoid arthritis, asthma, atherosclerosis, inflammatory bowel disease, COPD, insulin resistance, obesity-induced diabetes, multiple sclerosis and psoriasis. Chemokine-receptor antagonists are under active investigation.

chemokines

a large family of chemotactic cytokines which stimulate leukocyte movement.
