Extended Data Fig. 2: Analysis of Gzmk-tdTomato reporter expression across intestinal and lymphoid tissues in steady-state mice.

Flow cytometric analysis of lymphocytes from small intestinal intraepithelial lymphocytes (SI-IEL), small intestinal lamina propria lymphocytes (SI-LPL), large intestinal IEL (LI-IEL), large intestinal LPL (LI-LPL), Peyer’s patches (PP), and mesenteric lymph nodes (mLN) of Gzmk-tdTomato reporter mice at steady-state. Left panels: representative plots showing tdTomato signal in CD4⁺, CD8αα⁺, CD8αβ⁺, and γδ T cell subsets. Right panels: frequency of tdTomato⁺ cells within each subset (n = 5). Data are shown as mean ± s.e.m. and are representative of three independent experiments.
