BACKGROUND Allergic lung inflammation is caused by accumulation and activation of different leukocyte subsets, such as eosinophils and T lymphocytes, in the lung. The chemokines are a large group of chemotactic cytokines that regulate leukocyte trafficking and may play an important role in allergic lung inflammation. OBJECTIVE The purpose of this study was to evaluate the role of various chemokines, including eotaxin, RANTES, monocyte chemotactic protein (MCP)-1, macrophage inflammatory protein (MIP)-1beta, and IL-8 in the pathogenesis of eosinophilic pneumonia (EP). METHODS The concentrations of eotaxin, RANTES, MCP-1, MIP-1beta, and IL-8 in bronchoalveolar lavage fluid (BALF) were measured by using ELISA in 15 patients with EP, 10 with idiopathic pulmonary fibrosis, 10 with sarcoidosis, and 11 healthy volunteers. RESULTS Eotaxin in BALF was high only in patients with EP, and its level correlated significantly with the number of eosinophils in BALF of patients with EP and healthy volunteers. MCP-1 and MIP-1beta in BALF were preferentially increased in patients with EP. There was a significant correlation between MCP-1 levels and the number of macrophages in BALF of patients with EP and healthy volunteers. CONCLUSIONS Our findings suggest that these CC chemokines contribute to the pathogenesis of EP through the specific recruitment of leukocyte subsets in the lung.

D016207 Cytokines Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialized glands. They generally act locally in a paracrine or autocrine rather than endocrine manner. Cytokine
D016209 Interleukin-8 A member of the CXC chemokine family that plays a role in the regulation of the acute inflammatory response. It is secreted by variety of cell types and induces CHEMOTAXIS of NEUTROPHILS and other inflammatory cells.
