Analysis of B cells and T cells in the peritoneal cavity fluid after intraperitoneal injection of A/WSN/1933 virus in C57BL/6J wild type mice and CD83 KO mice. Wild type mice and CD83 KO mice (n = 5/group) were injected intraperitoneally with 5 × 10⁶ pfu of A/WSN/1933 virus. Peritoneal cells were harvested at 5, 7, and 14 days after infection. a FSC^lowSSC^low cells of peritoneal cavity fluid were sorted into B-1 cells (CD19⁺, CD23⁻) and B-2 cells (CD19⁺, CD23⁺). b FSC^lowSSC^low cells of peritoneal cavity fluid were sorted into CD4⁺ and CD8⁺ subsets. The bar diagram on the right side showed the absolute number of cells in each subgroup. **P < 0.01, ***P < 0.001
