Thymic egression of SS. (A) Schematic of recombination events in TCR rearrangement to generate signal joint TRECs and coding joint TRECs. (B) Quantification of sjTREC via real-time qPCR from naïve T cells from peripheral blood of CTCL patients that are CD4⁺CD26⁻ (n = 6) or CD4⁺CD26⁺ (n = 3) compared to age-matched healthy donors (n = 6), cord blood, benign ovarian tumor peripheral patient blood, and sample matched CD14⁺CD3⁻ monocytes (n = 6) using total DNA. Data are presented as mean ± standard error of the mean (SEM). ∗P < .05. Unpaired 2-tailed t test was used for calculating differences between means between experimental groups.
