The TCR δ Repertoire in Normal Human Skin is Restricted and Distinct from the TCR δ Repertoire in the Peripheral Blood [PDF]

Journal of Investigative Dermatology, 2001
The skin and the intestinal mucosa form surfaces to external environments and share similarities in anatomic structure and immunologic defense. In healthy humans, intestinal gamma/delta T cells express a highly restricted gamma/delta T cell receptor repertoire whereas gamma/delta T cells of the skin were thought to express a polyclonal repertoire ...

Co-receptor CD8-mediated modulation of T-cell receptor functional sensitivity and epitope recognition degeneracy [PDF]

, 2013
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 ...

Chasing the chains by testing them twice: Immunological insights from TCR repertoire analysis [PDF]

, 2023
The adaptive immune system employs a large number of T cells, that each have a specificity defined by their T-cell receptor (TCR). Characterizing the TCR repertoire in humans and mice thus provides a way to address outstanding immunological questions ...

Longitudinal analysis reveals age-related changes in the T cell receptor repertoire of human T cell subsets

The Journal of Clinical Investigation, 2022
A diverse T cell receptor (TCR) repertoire is essential for protection against a variety of pathogens, and TCR repertoire size is believed to decline with age.

Characterization of human cytomegalovirus peptide-specific CD8⁺ T-cell repertoire diversity following in vitro restimulation by antigen-pulsed dendritic cells [PDF]

, 2002
Under conditions of impaired T-cell immunity, human cytomegalovirus (HCMV) can reactivate from lifelong latency, resulting in potentially fatal disease.

The Current Status of T Cell Receptor (TCR) Repertoire Analysis in Colorectal Cancer. [PDF]

Int J Mol Sci
The rapid increase in colorectal cancer (CRC) cases recently has highlighted the need to use predictive biomarkers to guide therapeutic approaches. Current studies have focused on the tumor-infiltrating lymphocytes present in the tumor microenvironment ...

Analysis of the paired TCR α- and β-chains of single human T cells. [PDF]

, 2012
Analysis of the paired i.e. matching TCR α- and β-chain rearrangements of single human T cells is required for a precise investigation of clonal diversity, tissue distribution and specificity of protective and pathologic T-cell mediated immune responses.

Deciphering the TCR Repertoire to Solve the COVID-19 Mystery [PDF]

Trends in Pharmacological Sciences, 2020
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected several millions and killed more than quarter of a million worldwide to date. Important questions have remained unanswered: why some patients develop severe disease, while others do not; and what roles do genetic variabilities play in the individual immune response to this ...

Time-spatial analysis of T cell receptor repertoire in esophageal squamous cell carcinoma patients treated with combined radiotherapy and PD-1 blockade

OncoImmunology, 2022
T cell receptor (TCR) repertoire as a biomarker for predicting immunotherapy efficiency has been widely studied. However, its dynamics during radiotherapy combined with PD-1 blockade is little known. Using paired tumor and blood samples from the phase Ib

Studies of suppression using monoclonal regulatory T cells and the importance of co-receptor Lck coupling ratios for negative selection [PDF]

, 2015
Normal physiology is not given without immunological tolerance. Depending on the origin of induction, tolerance can be divided into central and peripheral tolerance.
