Immune effector cells via Fc receptor modulation

Molecular classification
Receptor, Immunoglobulin Receptor, Fc Receptor, Cell Surface Receptor
01

Overview

Immune effector cells, such as NK cells, macrophages, and neutrophils, are regulated through their expression of Fc receptors (FcRs). These receptors bind to the Fc region of antibodies bound to target antigens, triggering immune effector functions like phagocytosis, ADCC, and cytokine release. Modulation of FcR interactions, through protein engineering or glycoengineering of antibodies, is a key strategy for enhancing cancer immunotherapy or reducing unwanted inflammation.
