Immunoglobulin A1 (IgA1)

Target: IgA1
Molecular classification: Antibody, Immunoglobulin

Overview

Immunoglobulin A1 is a major antibody subclass specialized for protecting mucosal surfaces through neutralization mechanisms. Its unique structural features make it effective yet vulnerable to targeted cleavage by certain bacterial pathogens—a key factor influencing host-pathogen interactions on body surfaces exposed to external environments.
