The T-Cell Receptor

Diversity of T-cell receptor Gene Rearrangements in South Indian Patients with Common Acute Lymphoblastic Leukemia

Background: Precursor B-Acute Lymphoblastic Leukemia (precursor B-ALL) oc-curs due to the uncontrolled proliferation of B-lymphoid precursors arrested at a par-ticular stage of B-cell development. Precursor-B-ALL is classified mainly into pro-B-ALL, common-ALL and pre-B-ALL. The Common Acute Lymphoblastic Antigen CD10 is the marker for common-ALL. Objective: This study was aimed to examine the ...

T cell gamma receptor.

T cell receptor signalling.

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 ε, δ, γ and ζ subunits of the TCR. Phosphorylated ITAMs promote the recruitment and subsequent activation of another tyrosine kinase ZAP-70. Two known substrates of...

Advancing Chimeric Antigen Receptor-Engineered T-Cell Immunotherapy Using Genome Editing Technologies: Challenges and Future Prospects

Chimeric antigen receptor engineered-T (CAR-T) cells also named as living drugs, have been recently known as a breakthrough technology and were applied as an adoptive immunotherapy against different types of cancer. They also attracted widespread interest because of the success of B-cell malignancy therapy achieved by anti-CD19 CAR-T cells. Current genetic toolbox enabled the synthesis of CARs ...

The T-cell-receptor signaling network.

T-cell-receptor (TCR) signaling in response to antigen recognition has a central role in the adaptive immune response. Furthermore, the comprehensive nature of the TCR signaling network is such that it has become a model system for complex cellular responses ranging from gene regulation to cytoskeletal remodeling. Over the past five years, our understanding of TCR signaling has evolved on a num...
