Early responses to infection: chemokines as mediators of inflammation

Chemokines are a superfamily of small related protein molecules that are secreted by a variety of cells and that have, among their diverse biological properties, the ability to recruit a wide range of immune cells to the sites of infection and disease. Chemokines are secreted in response to bacterial, viral, parasitic, and mycobacterial pathogens. Our recent progress in understanding the patterns of chemokine secretion in response to various pathogens and their impact on disease manifestations is likely to lead to the development of novel therapeutic approaches for a variety of serious infections.
