Anti tcr γδ tcr 1

Isolated LP cells were analyzed using FACS Canto II (BD, Franklin Lakes, NJ, USA). Dead cells were excluded using Live/Dead fixable dead cell stain (Thermo Fisher Scientific, Waltham, MA, USA). The following anti-chicken antibodies were used for staining: anti-CD3 (CT-3; Southern Biotech, Birmingham, AL, USA), anti-CD4 (CT-4; Southern Biotech, Birmingham, AL, USA), anti-CD8a (CT-8; Southern Biotech, Birmingham, AL, USA), anti-TCR γδ (TCR-1; Southern Biotech, Birmingham, AL, USA), anti-MHC II (2G11; Southern-Biotech, Birmingham, AL, USA), anti-Bu-1 (AV20; Southern Biotech, Birmingham, AL, USA), and anti-Monocyte/Macrophage (KUL01; Southern Biotech, Birmingham, AL, USA). All antibodies were diluted 1:200 in PBS and incubated for 30 min under dark conditions. Then, all samples were fixed using 4% paraformaldehyde (PFA) and stored at 4 °C until analysis. The analysis was conducted by two panels: (1) MHC II, Bu-1, and monocyte/macrophage for B cells and APCs; (2) CD3, CD4, CD8a, and TCR γδ for T cells. For the detailed gating strategy of flow cytometry analysis, refer to Supplementary Figure S1.
