Article Title: CD49b defines functionally mature Treg cells that survey skin and vascular tissues
doi: 10.1084/jem.20181442
Figure Lengend Snippet: Treg cells stably express CD49b in a maturation-dependent manner. (A) Percentage of CD49b + cells among Treg cells stimulated in culture with α-CD3/CD28 and IL-2 for 4 or 8 d. (B) Percentage of CD62L + or CD49b + cells among aTreg cells in tissues of 5-d-old or 8-wk-old mice. (C) Expression of Rag2 GFP in Treg subsets from 4-wk-old Rag2 GFP mice. (D) Quantification of C. **, P ≤ 0.01 by paired t test; ns, not significant. (E) The indicated Foxp3 GFP Treg subsets were separately transferred into sublethally irradiated congenic Foxp3 GFP mice. Shown is the expression of CD49b versus dilution of CTV by transferred Treg cells recovered from spleen after 6 d. (F) Quantification of CD49b expression by transferred Treg cells. Data are representative of two independent experiments. Bars depict means ± SD.
Article Snippet: Single-cell suspensions were restimulated in U-bottom plates with 50 ng/ml PMA and 500 ng/ml ionomycin or 5 µg/ml soluble α-CD3 (clone 145-2C11; BioXCell) and 5 µg/ml soluble α-CD28 (clone 37.51; BioXCell), both in the presence of 1 µg/ml brefeldin A.
Techniques: Stable Transfection, Expressing, Irradiation
