Secreted 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 کاملImmune 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 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 کاملTicks produce highly selective chemokine binding proteins with antiinflammatory activity
Bloodsucking parasites such as ticks have evolved a wide variety of immunomodulatory proteins that are secreted in their saliva, allowing them to feed for long periods of time without being detected by the host immune system. One possible strategy used by ticks to evade the host immune response is to produce proteins that selectively bind and neutralize the chemokines that normally recruit cell...
متن کاملMolecular determinants for CC-chemokine recognition by a poxvirus CC-chemokine inhibitor.
Poxviruses express a family of secreted proteins that bind with high affinity to chemokines and antagonize the interaction with their cognate G protein-coupled receptors (GPCRs). These viral inhibitors are novel in structure and, unlike cellular chemokine receptors, are able to specifically interact with most, if not all, CC-chemokines. We therefore sought to define the structural features of C...
