  The invention relates to a method for modulating an interaction between an MR1 polypeptide and an MR1-specific T cell receptor molecule, whereby a MR1 polypeptide is contacted with a MR1 ligand compound that is a nucleobase adduct product reflecting a state of metabolic distress of a eukaryotic cell. The invention further relates to the use of compounds identified as MR1 ligands in vaccination or modulation of an MR1-restricted immune response.

  本发明涉及一种调节MR1多肽与MR1特异性T细胞受体分子之间相互作用的方法，其中MR1多肽与MR1配体化合物接触，MR1配体化合物是反映真核细胞代谢窘迫状态的核碱基加合物产物。 本发明进一步涉及鉴定为 MR1 配体的化合物在疫苗接种或调节 MR1 限制性免疫反应中的用途。

  The present invention relates to high-throughput methods comprising direct infusion electrospray ionization mass spectrometry (ESI-MS), multistep tandem mass spectrometry (MSn), consecutive reaction monitoring (CRM), ion mobility spectrometry mass spectrometry (IMS-MS), high-resolution MS, and IMS-MS, for genome-wide (whole cell or tissue) profiling of DNA and RNA nucleotides/nucleosides having a wide variety of variant structural modifications. In particular, these methods are contemplated for providing a specific profile of variant DNA and/or RNA chemically modified nucleic acids (i.e. structures) associated with specific medical conditions. Medical conditions may include, but are not limited to: cancer; including prostate, lung, uterus, larynx, ovary, breast, kidney, and many other types of cancers; specific stages of cancer; bacterial infections; viral infections; genetic and metabolic disorders; and any condition involving changes in DNA and/or RNA structural modifications.
