The T cell receptor/CD3 complex is composed of at least two autonomous transduction modules [PDF]

open access: yes, 1992
Recent studies have demonstrated that the CD3-ζ subunit of the T cell antigen receptor (TCR) complex is involved in signal transduction. However, the function of the remaining invariant subunits, CD3-γ, -δ, and , is still poorly understood.

The RhoA transcriptional program in pre-T cells [PDF]

open access: yes, 2007
The GTPase RhoA is essential for the development of pre-T cells in the thymus. To investigate the mechanisms used by RhoA to control thymocyte development we have used Affymetrix gene profiling to identify RhoA regulated genes in T cell progenitors.

The CD3-zeta chimeric antigen receptor overcomes TCR Hypo-responsiveness of human terminal late-stage T cells. [PDF]

open access: yesPLoS ONE, 2012
Adoptive therapy of malignant diseases with tumor-specific cytotoxic T cells showed remarkable efficacy in recent trials. Repetitive T cell receptor (TCR) engagement of target antigen, however, inevitably ends up in hypo-responsive cells with terminally ...

MHC‐restricted T cell receptor signaling is required for αβ TCR replacement of the pre T cell receptor [PDF]

open access: yesEuropean Journal of Immunology, 2008
AbstractA developmental block is imposed on CD25+CD44– thymocytes at the β‐selection checkpoint in the absence of the pre T cell receptor (preTCR) α‐chain, pTα. Early surface expression of a transgenic αβ TCR has been shown to partially circumvent this block, such that thymocytes progress to the CD4+CD8+ double‐positive stage.

LKB1 is essential for the proliferation of T-cell progenitors and mature peripheral T cells [PDF]

open access: yes, 2010
The serine/threonine kinase LKB1 has a conserved role in Drosophila and nematodes to co-ordinate cell metabolism. During T lymphocyte development in the thymus, progenitors need to synchronize increased metabolism with the onset of proliferation and ...

Cryptosporidium parvum infection in T-cell receptor (TCR)-alpha- and TCR-delta-deficient mice [PDF]

open access: yesInfection and Immunity, 1996
Mice deficient in either alpha beta or gamma delta T cells were more susceptible to infection with the protozoan parasite Cryptosporidium parvum than were control mice. Both neonatal and adult alpha beta-T-cell-deficient mice developed chronic infection. Gamma delta-T-cell-deficient neonatal mice were more susceptible than control mice but were able to

Cord blood Vα24-Vβ11 natural killer T cells display a Th2-chemokine receptor profile and cytokine responses [PDF]

open access: yes, 2011
Background: The fetal immune system is characterized by a Th2 bias but it is unclear how the Th2 predominance is established. Natural killer T (NKT) cells are a rare subset of T cells with immune regulatory functions and are already activated in utero ...

Nanoscale kinetic segregation of TCR and CD45 in engaged microvilli facilitates early T cell activation

open access: yesNature Communications, 2018
T cell activation is critically controlled by T cell receptor (TCR) signalling. Here the authors show, using live cell imaging, atomic force microscopy and modelling simulation, a prompt separation of TCR and CD45 that negatively correlates with TCR ...

Generation of diffuse large B cell lymphoma-associated antigen-specific Vα6/Vβ13+T cells by TCR gene transfer

open access: yesJournal of Hematology & Oncology, 2011
Background Our previous study had amplified antigen-specific full-length TCR α and β genes of clonally expanded T cells in the peripheral blood (PB) of patients with diffuse large B-cell lymphoma (DLBCL).

Indian hedgehog (Ihh) both promotes and restricts thymocyte differentiation [PDF]

open access: yes, 2009
We show that Indian Hedgehog (Ihh) regulates T-cell development and homeostasis in both fetal and adult thymus, controlling thymocyte number. Fetal Ihh-/- thymi had reduced differentiation to double-positive (DP) cell and reduced cell numbers compared ...
