The function of T-cell receptor (TCR) gene modified T cells is dependent on efficient surface expression of the introduced TCR α/β heterodimer. We tested whether endogenous CD3 chains are rate-limiting for TCR expression and antigen-specific T-cell function. We show that co-transfer of CD3 and TCR genes into primary murine T cells enhanced TCR expression and antigen-specific T-cell function in ...

Although individual T lymphocytes have the potential to generate two distinct T cell receptor (TCR)-beta chains, they usually express only one allele, a phenomenon termed allelic exclusion. Expression of a functional TCR-beta chain during early T cell development leads to the formation of a pre-T cell receptor (pre-TCR) complex and, at the same developmental stage, arrest of further TCR-beta re...

We describe a simple iterative approach to augment TCR affinity, which we studied using a myelin oligodendrocyte glycoprotein-specific TCR. We hypothesized that single amino acid modifications in TCR CDR3 could enhance TCR sensitivity through focal interactions with antigenic peptide while minimizing the risk of cross-reactivity observed previously in TCR more broadly mutagenized using in vitro...

Expression and function of the antigen T cell receptor (TCR) play a central role in regulating immune responsiveness. Accordingly, targeting the expression of TCR or its associated CD3 subunits profoundly influences T cell development and adaptive immunity. Down-regulation of the invariant TCR chain has been documented in a wide variety of chronic inflammatory and infectious diseases, and is th...

Adoptive transfer of antigen-specific T cells is an attractive strategy for the treatment of hematologic malignancies. It has been shown that T cells recognizing minor histocompatibility antigens (mHag) selectively expressed on hematopoietic cells mediate antileukemic reactivity after allogeneic stem cell transplantation. However, large numbers of T cells with defined specificity are difficult ...

Adoptive T cell therapy that collected from the patient’s blood for treating cancer and chronic infections has revolutionized field of oncology personalized medicine. However, such highly activated cells have specific receptor (TCR) against target disease are usually greatly outnumbered by not-activated due to stochastic generation TCR V(D)J recombination, approximately 106∼107 possible TCR. In...

The cover picture shows the electrochemical detection of dihydroxy benzene by nano-electrocatalysts based on carbonaceous nanomaterials (i.e., carbon nanotubes, graphene, and their derivatives) non-carbonaceous metal-organic frameworks, molecular imprinted polymers, other nanomaterials).

Mycosis fungoides (MF), the most common type of cutaneous T-cell lymphoma, has various unspecific clinical and histological characteristics. Its early diagnosis is challenging. The application of T-cell receptor (TCR) gene clonal rearrangement to the diagnosis of MF has been widely studied. In this study, we used polymerase chain reaction (PCR) to investigate the diagnostic significance of dete...
