Review explores CRP’s possible role in VEEV brain disease

A new review in Reviews in Medical Virology examines whether C-reactive protein, or CRP, could play a meaningful role in central nervous system injury during Venezuelan equine encephalitis virus infection. The paper focuses on how VEEV, a mosquito-borne alphavirus that affects equids and people, triggers neuroinflammation after entering the brain, including glial activation, blood-brain barrier disruption, and neuronal injury. While the article appears to be a hypothesis-driven review rather than a new clinical trial or field study, it adds to a growing body of literature arguing that host inflammatory pathways, not just viral replication, shape neurologic disease severity in VEEV infection.

Why it matters: For veterinary professionals, the review is a reminder that VEEV pathogenesis in horses likely depends on both viral neuroinvasion and the host response inside the CNS. That matters because blood-brain barrier permeability, complement activity, toll-like receptor signaling, and other inflammatory pathways have already been implicated in VEEV neuropathogenesis in experimental work, suggesting that biomarkers such as CRP may eventually help frame prognosis, monitoring, or future therapeutic research, even if they are not yet part of routine equine decision-making. VEE remains a serious animal and public health concern in the Americas, with horses serving as key amplifying hosts during epizootics. (pmc.ncbi.nlm.nih.gov)

What to watch: Watch for follow-up studies that test whether CRP is actually measurable in equine or experimental VEEV CNS disease, and whether it correlates with blood-brain barrier injury, neurologic severity, or outcomes. (experts.illinois.edu)
