Cathepsin K Mediates the Formation of Potential Rheumatoid Arthritis-Relevant Cis- and Trans-Spliced Peptides Compatible With HLA-DR4 Presentation

Quote: Rheumatoid arthritis (RA) is characterized by a loss of immunological tolerance to synovial self-proteins, yet the initial triggers generating novel neo-antigens remain incompletely defined. Here, we demonstrate that human cathepsin K (hCatK), a key cysteine protease driving joint degradation in RA, catalyzes covalent cis- and trans- splicing of peptides from major RA-associated self-proteins and foreign antigens, including type II collagen, fibrinogen, and SARS-CoV-2 Spike protein.
