T cell receptor (TCR) recognition of foreign peptides presented by major histocompatibility complex protein is a major event in triggering the adaptive immune response to pathogens or cancer. The prediction of TCR-peptide interactions has great importance for therapy of cancer as well as infectious and autoimmune diseases but remains a major challenge, particularly for novel (unseen) peptide epitopes. Here we present TCRen, a structure-based method for ranking candidate unseen epitopes for a given TCR.

How T-cell receptor (TCR) characteristics determine subset commitment during T-cell development is still unclear. Here, we addressed this question for innate-like T cells, mucosal-associated invariant T (MAIT) cells, and invariant natural killer T (iNKT) cells. MAIT and iNKT cells have similar developmental paths, leading in mice to two effector subsets, cytotoxic (MAIT1/iNKT1) and IL17-secreting (MAIT17/iNKT17).

Article Synopsis
  • - The study investigates T-cell receptor (TCR) recognition of peptides linked to the major histocompatibility complex (MHC) to enhance understanding of the adaptive immune response against pathogens, addressing the lack of structural data available.
  • - Researchers utilized the VDJdb database to identify and cluster specific TCR sequences and their CDR3 loops, employing advanced modeling techniques and the Rosetta software package to analyze amino acid interactions and optimize TCR-peptide-MHC contact.
  • - A database of 1585 modeled TCR-peptide-MHC structures was developed, revealing insights into the physicochemical properties that influence antigen recognition, thereby contributing to the creation of accurate models for future research in immunology.

Unlabelled: Treatment of craniovertebral junction meningioma is a difficult task. Surgical treatment is the gold standard for these patients. However, it is associated with high risk of neurological impairment, while combined treatment (surgery + radiotherapy) provides more favorable outcomes.
