Upon engagement of the TCR by antigen presented on major histocompatibility complex (MHC) molecules, the Src family kinase Lck is activated and proceeds to phosphorylate immunoreceptor tyrosine-based activation motifs (ITAMs) on the e, δ, γ and ζ subunits of the TCR.

Pre-T cell receptor localization and trafficking are independent of its signaling [PDF]
Expression of the pre-T cell receptor (preTCR) is an important checkpoint during the development of T cells, an essential cell type of our adaptive immune system.

CD95 co-stimulation blocks activation of naive T cells by inhibiting T cell receptor signaling [PDF]
CD95 is a multifunctional receptor that induces cell death or proliferation depending on the signal, cell type, and cellular context. Here, we describe a thus far unknown function of CD95 as a silencer of T cell activation.

Co-receptor CD8-mediated modulation of T-cell receptor functional sensitivity and epitope recognition degeneracy [PDF]
The interaction between T-cell receptors (TCRs) and peptide epitopes is highly degenerate: a TCR is capable of interacting productively with a wide range of different peptide ligands, involving not only cross-reactivity proper (similar epitopes elicit ...

The transcriptional activator Gli2 modulates T-cell receptor signalling through attenuation of AP-1 and NFκ-B activity. [PDF]
Different tissues contain diverse and dynamic cellular niches, providing distinct signals to tissue-resident or migratory, infiltrating immune cells.

Cellular-level versus receptor-level response threshold hierarchies in T-Cell activation [PDF]
Peptide-MHC (pMHC) ligand engagement by T-cell receptors (TCRs) elicits a variety of cellular responses, some of which require substantially more TCR-mediated stimulation than others.

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

T cell development and T cell responses in mice with mutations affecting tyrosines 292 or 315 of the ZAP-70 protein tyrosine kinase [PDF]
After stimulation of the T cell receptor (TCR), the tyrosine residues 292 and 315 in interdomain B of the protein tyrosine kinase ZAP-70 become phosphorylated and plausibly function as docking sites for Cbl and Vav1, respectively. The two latter proteins

The T‐cell receptor repertoire of regulatory T cells [PDF]
SummaryThe CD4+ CD25+ regulatory population of T cells (Treg cells), which expresses the forkhead family transcription factor (Foxp3), is the key component of the peripheral tolerance mechanism that protects us from a variety of autoimmune diseases.
