Extended Data Fig. 5: Ctsl calibrates the positively selecting signal strength.

a, Thymocyte subset cell numbers (Mean ± SEM) in Ctsl+/+Rag1−/−Lm54Tg (n = 3) and CtslΔTECRag1−/−Lm54Tg mice (n = 4). b, Thymocyte subset cell numbers (Mean ± SEM) in Ctsl+/+Rag1−/−Lm6Tg (n = 6) and CtslΔTECRag1−/−Lm6Tg mice (n = 7). c, CD6 surface expression (MFI ± SEM) at consecutive DP and CD4SP differentiation stages in Ctsl+/+Rag1−/−Lm54Tg (n = 4) and CtslΔTECRag1−/−Lm54Tg mice (n = 5), assessed by flow cytometry. P-value by Student’s two-tailed t-test.
