Figure 1. CD69+CD103+ Trm-like Cells Are Rarely Observed in the Peripheral Blood.

Figure 1

(A) Representative flow cytometry panels showing expressions of CD69 and CD103 on naive (CD45RA+) and memory (CD45RA−) T cells in the peripheral blood. (B) The frequency of CD69+CD103+ double-positive (DP) population is higher in memory than in naïve CD8+ T cells in the peripheral blood. (C) The frequency of CD69+CD103+ DP population is higher in memory than in naïve CD4⁺ T cells in the peripheral blood. (D) The frequency of CD69+CD103+ DP population tended to be higher in CD8+ T cells in the peripheral blood. Data are mean ± SD; paired t test (B-D) HC = healthy control; NMOSD = neuromyelitis optica spectrum disorder.
