Fig. 5From: Fetal thymus graft enables recovery from age-related hearing loss and expansion of CD4-Positive T cells expressing IL-1 receptor type 2 and regulatory T CellsGating for IL-1R1, IL-1R2, and FR4 on CD4+ T cells. Surface markers of IL-1R1 (a), IL-1R2 (b), and FR4 (c) on CD4+ T cells were examined using FITC-conjugated anti-mouse CD4 cell mAb, PE-conjugated anti-mouse CD121a (IL-1R1) mAb, PE-conjugated anti-mouse CD121b (IL-1R2) mAb, and biotin-conjugated anti-mouse FR4 (nTreg) mAb plus streptavidin-RED670 with flow cytometry. a) Square R1, b) square R2, and c) square R3 include CD121a+ CD4+ cells, CD121b+ CD4+ cells, and FR4hi CD4+ cells, respectivelyBack to article page
