Protective efficacy of IFNα/γ@PAMgel against PRV infection in mice. A Survival rates of mice after challenge. B Viral DNA copies in different tissues (spleen, lung, and brain). Viral DNA copies were quantified for each tissue using qPCR and calculated as viral DNA copies per microliter. The data are presented as the mean ± standard deviation from three experiments. The statistical significance of differences between IFNα/γ@PAMgel-treated and untreated groups was determined using Student’s t tests (**p < 0.01; ***p < 0.001; ns, not significant).
