background: an association between lung cancer and chemokines has been advocated in the recent years. this study aims at investigating the association between lung cancer and 16c/a single nucleotide polymorphism (snp) (rs. 4359426) in c-c motif chemokine 22 (ccl22) as well as c1014t snp (rs. 2228428) in c-c chemokine receptor type 4 (ccr4), which serves as the receptor for ccl22. methods: genot...

Kunkel reviewed the organization of the chemokine system and its important role in the development, differentiation, and deployment of mammalian leukocytes (1). The system is massive (about 50 ligands and 18 receptors are known), reflecting the complexity of its major client, the immune system. Now in this issue of the JCI, Liu and colleagues remind us that an antichemokine system has evolved i...

High mobility group box 1 (HMGB1) protein, a late mediator of lethality in sepsis, can induce acute inflammatory lung injury. Here, we identify the critical role of alpha-chemokine receptors in the HMGB1-induced inflammatory injury and show that alpha-chemokine receptor inhibition increases survival in sepsis, in a clinically relevant time frame. Intratracheal instillation of recombinant HMGB1 ...

The erythrocyte chemokine receptor is a cell surface protein that binds a wide array of chemokines including interleukin-8 (IL-8), melanoma growth stimulating activity (MGSA), monocyte chemotactic protein-1 (MCP-1), and RANTES (Regulated on Activation, Normal T Expressed and Secreted). This protein has also been identified as the Duffy blood group antigen, a cell surface receptor for the malari...

Note CCR1, a member of the beta chemokine receptor family, is a seven transmembrane protein similar to G protein-coupled receptors. CCR1 is the first human CC chemokine receptor to be identified at the cDNA level. It has a functional viral homolog, US28, which is a human cytomegalovirus.The ligands of this receptor include macrophage inflammatory protein 1 alpha (MIP-1 alpha), regulated on acti...

Chemokines mediate trafficking of leukocytes to sites of inflammation and immune responses through activation of G protein-coupled receptors, which thereby provide appealing targets for novel anti-inflammatory agents. Vasoactive intestinal peptide (VIP) is an immunosuppressive neurotransmitter. We show that VIP inhibited the function of chemokine receptors on monocytes and CD4(+) T lymphocytes,...
