Releasing the concept of HLA-allele specific peptide anchors in viral infections: A non-canonical naturally presented human cytomegalovirus-derived HLA-A*24:02 restricted peptide drives exquisite immunogenicity.

ABSTRACT: T-cell receptors possess the unique ability to survey and respond to their permanently modified ligands, self HLA-I molecules bound to non-self peptides of various origin. This highly specific immune function is impaired following hematopoietic stem cell transplantation (HSCT) for a timespan of several months needed for the maturation of T-cells. Especially, the progression of HCMV disease in immunocompromised patients induces life-threatening situations. Therefore, the need for a new immune system that delivers vital and potent CD8+ T-cells carrying TCRs that recognize even one human cytomegalovirus (HCMV) peptide/HLA molecule and clear the viral infection long term becomes obvious. The transcription and translation of HCMV proteins in the lytic cycle is a precisely regulated cascade of p
