Destabilizing the autoinhibitory conformation of Zap70 induces up-regulation of inhibitory receptors and T cell unresponsiveness. [PDF]

open access: yes, 2017
Zap70 plays a critical role in normal T cell development and T cell function. However, little is known about how perturbation of allosteric autoinhibitory mechanisms in Zap70 impacts T cell biology.

A Long-Playing CD about the γδ TCR Repertoire [PDF]

open access: yesImmunity, 2013
In this issue of Immunity, a study by Luoma et al. (2013) provides structural evidence for direct interactions of human Vδ1(+) T cell receptors with CD1d, capping a long trail of evidence that CD1 might be a major influence on γδ T cell biology.

Autoencoder based local T cell repertoire density can be used to classify samples and T cell receptors.

open access: yesPLoS Computational Biology, 2021
Recent advances in T cell repertoire (TCR) sequencing allow for the characterization of repertoire properties, as well as the frequency and sharing of specific TCR. However, there is no efficient measure for the local density of a given TCR.

Individual Epitope-Specific CD8+ T Cell Immune Responses Are Shaped Differently during Chronic Viral Infection

open access: yesPathogens, 2023
A hallmark in chronic viral infections are exhausted antigen-specific CD8+ T cell responses and the inability of the immune system to eliminate the virus.

Models of self-peptide sampling by developing T cells identify candidate mechanisms of thymic selection [PDF]

open access: yes, 2013
Conventional and regulatory T cells develop in the thymus where they are exposed to samples of self-peptide MHC (pMHC) ligands. This probabilistic process selects for cells within a range of responsiveness that allows the detection of foreign antigen ...

A novel signature for stratifying the molecular heterogeneity of the tissue-infiltrating T-cell receptor repertoire reflects gastric cancer prognosis

open access: yesScientific Reports, 2017
Many basic properties of the T-cell receptor (TCR) repertoire require clarification, and the changes occurring in the TCR repertoire during carcinogenesis, especially during precancerous stages, remain unclear. This study used deep sequencing analyses to

Quantifiable blood TCR repertoire components associate with immune aging. [PDF]

open access: yesNat Commun
Abstract T cell senescence results in decayed adaptive immune protection in older individuals, with decreased or increased abundance of certain T cell phenotypic subpopulations. However, no study has linked aging to the dynamic changes of T cell clones.

RAGs and Regulation of Autoantibodies [PDF]

open access: yes, 2004
Autoreactive antibodies are etiologic agents in a number of autoimmune diseases. Like all other antibodies these antibodies are produced in developing B cells by V(D)J recombination in the bone marrow.

Correlations in the T Cell Response to Altered Peptide Ligands

open access: yes, 2004
The vertebrate immune system is a wonder of modern evolution. Occasionally, however, correlations within the immune system lead to inappropriate recruitment of preexisting T cells against novel viral diseases.

MARCH1 protects the lipid raft and tetraspanin web from MHCII proteotoxicity in dendritic cells [PDF]

open access: yes, 2018
Dendritic cells (DCs) produce major histocompatibility complex II (MHCII) in large amounts to function as professional antigen presenting cells. Paradoxically, DCs also ubiquitinate and degrade MHCII in a constitutive manner.
