Summary
This prospective observational study examined whether genetic risk for necrotizing meningoencephalitis (Pug dog encephalitis), defined by a chromosome 12 haplotype, associates with alterations in blood immunology prior to disease onset. In asymptomatic Pugs, high and medium genetic risk animals exhibited significantly lower CD4+ T cell proportions and elevated IL-10 concentrations compared to low-risk animals, suggesting an immunological basis for disease susceptibility that may inform future diagnostic and therapeutic development.
UK applicability
This study addresses canine disease mechanisms and is not directly applicable to UK agricultural or human nutrition policy. However, the immunogenetic approach may inform comparative veterinary medicine practice in the UK regarding breed-predisposed neuroinflammatory conditions.
Key measures
CD4+ T cell proportion (%), plasma IL-10 concentration (pg/mL), NME risk haplotype frequency, leukocyte subset characterisation by flow cytometry
Outcomes reported
The study measured blood cytokine concentrations and leukocyte subset proportions in asymptomatic Pugs stratified by genetic risk haplotype for necrotizing meningoencephalitis. Findings included altered CD4+ T cell proportions and elevated interleukin-10 in high and medium-risk animals.
