Thymocytes can tolerize thymocytes by clonal deletion in vitro [PDF]
Clonal deletion of thymocytes bearing TCR for self antigens is one major mechanism of T cell tolerance induction. Peptide antigen-induced deletion of thymocytes from αβ TCR transgenic mice has been studied using single cell suspension cultures. The results show that antigen-presenting immature CD4+CD8+ thymocytes can tolerize antigen-reactive immature ...

Summary: T cell differentiation in the thymus proceeds in an ordered sequence of developmental events characterized by variable expression of CD4 and CD8 coreceptors. Here, we report that immature single-positive (ISP) thymocytes are molecularly distinct

Interleukin-21 accelerates thymic recovery from glucocorticoïd-induced atrophy. [PDF]
Both physiological and psychological stress cause thymic atrophy via glucocorticoïd (GC)-dependent apoptosis of double-positive (DP) thymocytes. Given the pervasiveness of stress, GC-induced thymic atrophy is arguably the most common type of acquired ...

A quantitative study of the mechanisms behind thymic atrophy in Gαi2-deficient mice during colitis development. [PDF]
Mice deficient for the G protein subunit Gαi2 spontaneously develop colitis, a chronic inflammatory disease associated with dysregulated T cell responses.

Phenotypic markers that denote different developmental stages of thymocytes are important for understanding T cell development in the thymus. Here, we show that CD1b is a critical discriminator of thymocyte maturation stage in cynomolgus monkeys.

Thymocyte differentiation is dependent on the availability and transport of metabolites in the thymus niche. As expression of metabolite transporters is a rate-limiting step in nutrient utilization, cell surface transporter levels generally reflect the ...

Critical role of WNK1 in MYC-dependent early mouse thymocyte development
WNK1, a kinase that controls kidney salt homeostasis, also regulates adhesion and migration in CD4+ T cells. Wnk1 is highly expressed in thymocytes, and since migration is important for thymocyte maturation, we investigated a role for WNK1 in mouse ...

Selective reduction of post-selection CD8 thymocyte proliferation in IL-15Rα deficient mice. [PDF]
Peripheral CD8(+) T cells are defective in both IL-15 and IL-15Rα knock-out (KO) mice; however, whether IL-15/IL-15Rα deficiency has a similar effect on CD8 single-positive (SP) thymocytes remains unclear.

Thymocytes trigger self-antigen-controlling pathways in immature medullary thymic epithelial stages
Interactions of developing T cells with Aire+ medullary thymic epithelial cells expressing high levels of MHCII molecules (mTEChi) are critical for the induction of central tolerance in the thymus.

Immature thymocyte antigen-1: a novel thymocyte marker discriminating pre- and post-selected thymocytes [PDF]
Previously, we described a mAb (1-23) reacting with a novel cell surface antigen expressed on thymocytes at late CD4-CD8- [(double negative (DN)] to early CD4+CD8+ [(double positive (DP)] differentiation stage. Since the expression of this molecule was restricted to immature thymocytes, we designated it as immature thymocyte antigen-1 (IMT-1).
