Identification of bacterial protease domains that cleave human IgM
Copyright © 2023 The Authors. Published by Elsevier Inc. All rights reserved..
Immunoglobulin-degrading proteases are secreted by pathogenic bacteria to weaken the host immune response, contributing to immune evasion mechanisms during an infection. Proteases specific to IgG and IgA immunoglobulin classes have previously been identified and characterized, and only a single report exists on a porcine specific IgM-degrading enzyme. It is unclear whether human pathogens also produce enzymes that can break down human IgM. Here, we have identified four novel IgM-degrading proteases from different genera of human-infecting bacterial pathogens. All four protease domains cleave human IgM at a conserved and unique site in the constant region of IgM. These human IgM proteases may be a useful biochemical tool for the study of early immune responses and have therapeutic potential in IgM-mediated disease.
