Immune System Modulation via Induction of Blocking Antibodies (IgG4, IgA) (N/A)
- Target
- N/A
- Molecular classification
- Immunoglobulin, Antibody, IgG4, IgA
01
Overview
Immune system modulation through the induction of blocking antibodies—specifically immunoglobulin G4 (IgG4) and immunoglobulin A (IgA)—is a strategy that leverages the unique properties of these antibody subclasses to dampen or redirect immune responses. Unlike other antibody isotypes, IgG4 and IgA are generally associated with anti-inflammatory or tolerogenic effects rather than strong immune activation. It is not a single molecular entity but rather describes an immunological outcome—the upregulation/induction of specific non-inflammatory antibody classes as modulators within the broader context of adaptive immunity.

Mechanism of action
Induction of IgG4 and IgA antibodies that block antigen binding to effector cells, preventing downstream inflammatory signaling and effector functions.
