A Hierarchy of Intestinal Antigens Instructs the CD4+ T Cell Receptor Repertoire

I. Research Background The intestinal immune system must balance tolerance and defense against dietary antigens, microbiota-derived antigens, and self-antigens. Although CD4+ T cells are known to play a central role in gut immunity, how different antigen sources shape the composition of the T cell receptor (TCR) repertoire remains unclear. The trad...

Contrastive Learning of T Cell Receptor Representations

New Breakthrough in T Cell Receptor (TCR) Specificity Prediction: The Introduction of the SCEPTR Model Academic Background T cell receptors (TCRs) play a crucial role in the immune system by determining the specificity of immune responses through their binding to peptide-MHC complexes (pMHCs). Understanding the interaction between TCRs and specific...
