The replication of equine infectious anemia virus (EIAV) in macrophages not only leads to cell death, but also to the induction of a variety of cytokines that may affect immune function. Cytokine production may be responsible for the fever, anorexia, hemorrhages, lethargy or thrombocytopenia seen in the acute and chronic phases of equine infectious anemia (EIA). The study of the equine immune system and inflammatory responses, by measuring cytokine expression, can provide important insight into disease pathogenesis in the horse. We have extended studies of virulent and avirulent EIAV clones by examining the effects of Env proteins on cytokine expression in equine monocyte-derived macrophages (EMDM) using EIAV17, EIAV19, EIAV17SU, and EIAV17TM viruses. In the current studies a set of quantitative real-time polymerase chain reaction (QPCR) assays for the equine cytokines IL-1α, IL-1β, IL-6, IL-8 and TNF-α were validated using QPCR primers and probes which were generated for the aforementioned equine genes.
