Abstract

Highlights: Chemokines direct the migration of leukocytes to the site of infection playing a relevant role in the antiviral response. Some viruses express viral chemokine binding proteins (vCKBP) that modulate chemokine activity. Lack of vCKBP expression has profound consequences in pathogenesis in vivo . Similar proteins have been described in higher order organisms like parasites, ticks and even humans. Abstract: Chemokines are chemotactic cytokines whose main function is to direct cell migration. The chemokine network is highly complex and its deregulation is linked to several diseases including immunopathology, cancer and chronic pain. Chemokines also play essential roles in the antiviral immune response. Viruses have therefore developed several counter strategies to modulate chemokine activity. One of these is the expression of type I transmembrane or secreted proteins with the ability to bind chemokines and modulate their activity. These proteins, termed viral chemokine binding proteins (vCKBP), do not share sequence homology with host proteins and are immunomodulatory in vivo . In this review we describe the discovery and characterization of vCKBP, explain their role in the context of infection in vivo and discuss relevant novel findings.
