Possible selves reflect one's hopes and fears for their future identity. Previous research shows that high anxiety is associated with clearer feared possible selves. However, the mechanism through which clarity could maintain anxiety is relatively unexplored as are questions concerning whether clarity of possible selves could offer new methods of reducing anxiety.

: Adoptive cell therapy is the most promising approach for battling cancer, with T cell receptor-engineered T (TCR-T) cell therapy emerging as the most viable option for treating solid tumors. Current techniques for preparing TCR-T cell therapy provide a limited number of candidates TCRs, missing the comprehensive view of the repertoire, which may hinder the identification of the most effective TCRs. : Dendritic cells were primed with immunogenic peptides of the antigen of interest to expand antigen-specific CD8 T lymphocytes from peripheral blood.

The development of T cell receptor-engineered T cells (TCR-T) targeting intracellular antigens is a promising strategy for treating solid tumors; however, the mechanisms underlying their effectiveness remain poorly understood. In this study, we employed advanced techniques to investigate the functional state of T cells engineered with retroviral vectors to express a TCR specific for the NY-ESO-1 157-165 peptide in the HLA-A*02:01 context. Flow cytometry revealed a predominance of naïve T cells.

Article Synopsis
  • Adoptive cell therapy using TCR-engineered T-cells shows promise in targeting tumor cells, especially cancer-testis antigens in solid tumors, despite limited testing in this area compared to blood cancers.
  • The study introduced an innovative protocol for expanding MAGE-A3-specific T-cells and utilized advanced techniques like single-cell multi-omic analysis and lentiviral engineering to enhance T-cell effectiveness.
  • Results indicated a significant increase in MAGE-A3-specific T-cells, identification of a dominant T-cell receptor, and effective cytotoxic activity against MAGE-A3-positive tumors, highlighting the success of their methodology in generating potent anti-tumor T-cells.

Significant strides have been made in identifying tumour-associated antigens over the past decade, revealing unique epitopes crucial for targeted cancer therapy. Among these, the New York esophageal squamous cell carcinoma (NY-ESO-1) protein, a cancer/testis antigen, stands out. This protein is presented on the cell surface by major histocompatibility complex class I molecules and exhibits restricted expression in germline cells and various cancers, marking it as an immune-privileged site.
