Immune modulation by virus-encoded secreted chemokine binding proteins.
Chemokines are chemoattractant cytokines that mediate the migration of immune cells to sites of infection which play an important role in innate and adaptive immunity. As an immune evasion strategy, large DNA viruses (herpesviruses and poxviruses) encode soluble chemokine binding proteins that bind chemokines with high affinity, even though they do not show sequence similarity to cellular chemo...
متن کاملSecreted poxvirus chemokine binding proteins.
Poxviruses encode a variety of immunomodulatory proteins that subvert the cytokine networks of infected hosts. Myxoma virus, a poxvirus pathogen of rabbits, expresses two distinct 35- to 40-kDa secreted glycoproteins that bind a broad spectrum of chemokines. The first of these, designated M-T7, is encoded by the T7 gene and is the first example of what is here referred to as type-I chemokine bi...
متن کاملA Broad Spectrum Secreted Chemokine Binding Protein Encoded by a Herpesvirus
Chemokines are a family of small proteins that interact with seven-transmembrane domain receptors and modulate the migration of immune cells into sites of inflammation and infection. The murine gammaherpesvirus 68 M3 gene encodes a secreted 44-kD protein with no sequence similarity to known chemokine receptors. We show that M3 binds a broad range of chemokines, including CC, CXC, C, and CX(3)C ...
متن کاملViral chemokine-binding proteins.
The chemokines are a large family of small signaling proteins that bind to G-protein-coupled receptors (GPCRs) on target cells and mediate the directional migration of immune cells into sites of infection or inflammation. The large DNA viruses, particularly the poxviruses and herpesviruses, have evolved several mechanisms to corrupt the normal functioning of the chemokine network. Two strategie...
متن کاملStructural determinants of chemokine binding by an Ectromelia virus-encoded decoy receptor.
The EVM1 protein encoded by Ectromelia virus is a member of a highly conserved family of poxvirus chemokine binding proteins that interfere with host immune surveillance processes. EVM1 is abundantly expressed early during mousepox infection and is able to selectively bind CC chemokines and inhibit their interactions with host receptors. Here, we characterize the interaction between EVM1 and th...
