In cynomolgus macaques, infection with the isolate CHIKV-LR recapitulates common characteristics of the immune response, such as an increase in plasma levels of IFN-α/β, interleukin 6, and monocyte chemoattractant protein 1, correlating with peak levels of viremia (Labadie et al., 2010). The gene discussed is IFNA1; the disease is infection.
