Systems and methods for determining amino acid sequences of peptides that bind to MHC-I or HLA-I complex or MHC-II or HLA-II complex are provided. One embodiment includes isolating peptides from MHC or HLA class I or class II-peptide complexes and adding one or more known labeled peptides of interest to form a sample containing labeled peptides and unlabeled isolated peptides. The method also includes analyzing the sample with an LC-MS/MS system to obtain sequence data of the peptides, and increasing the sensitivity of the LC-MS/MS system when the labeled peptide is detected by the LC-MS/MS system. The method then concludes with determining the amino acid sequence of the unlabeled peptides in an m/z range that includes the m/z of the labeled peptide. The system can be triggered to increase the sensitivity in or near the m/z of the labeled peptide using an algorithm or computer program.

Systems and methods for identifying HLA-associated tumor peptides

The present invention provides antibodies that bind to protease-activated receptor-2 (PAR-2) and methods of using same. According to certain embodiments of the invention, the antibodies are fully human antibodies that bind to human PAR-2. The antibodies of the invention are useful, inter alia, for the treatment of diseases and disorders associated with one or more PAR-2 biological activities, including the treatment of pain conditions, inflammatory conditions and gastrointestinal conditions.

Methods of alleviating itch by administering human antibodies to human protease-activated receptor 2

The present invention provides methods for treating pruritus by blocking human protease activated receptor-2 (PAR2) activity. The methods of the invention can be used to treat pruritus associated with atopic dermatitis, psoriasis, burn scarring, hypertrophic scarring, keloids, renal failure or hepatic failure. The methods of the invention include administering an antibody or antigen-binding fragment thereof that specifically binds human PAR2.
