C-C motif chemokine ligand 22 (CCL22)

Target
CCL22
Molecular classification
Chemokine, Cytokine, Secreted protein (ligand for chemokine receptors such as CCR4), Family: CC chemokine family (two adjacent cysteines motif), Other: Signaling molecule
01

Overview

C-C motif chemokine ligand 22 (CCL22) is a small secreted protein of the CC chemokine family predominantly produced by dendritic cells and macrophages. It acts as a chemoattractant, particularly for memory T cells, natural killer cells, and dendritic cells, by binding to the CC chemokine receptor 4 (CCR4). The protein plays a central role in immune cell trafficking, the regulation of inflammatory responses, and is involved in the pathogenesis of various immune-related diseases, including cancer, allergies, and autoimmune disorders. It is a common subject of research in immunology and targeted therapy development.

02

Mechanism of action

Chemokine receptor antagonism (drugs interfere with CCL22 binding to CCR4, reducing immune cell recruitment); Immune modulation (by altering CCL22 signaling pathways, drugs can impact inflammatory responses)

03

Biological functions

Immune response (regulation and recruitment of immune cells)Signal transduction (through interaction with CCR4)Cell migration/chemotaxis (attracts T cells, dendritic cells, and other leukocytes)Inflammation (modulates inflammatory responses, especially in allergic and autoimmune conditions)
04

Disease associations

Cancer (associated with tumor microenvironment and immune cell recruitment)Inflammation (chronic inflammatory diseases)Infection (chemotactic for immune cells in infection settings)Other (modulation of allergy and autoimmune diseases)
05

Safety considerations

Therapeutic challenges include potential immunosuppression, off-target effects (altering recruitment of regulatory T cells or other immune cells), and risk of infections due to modulation of immune signaling
06

Interacting drugs

Specific therapeutics targeting CCL22 or its receptor CCR4 include investigational agents like CCR4 antagonists; CCL22 as a direct target is less common than its receptor CCR4. No approved drugs directly target CCL22, but it is implicated in the development and testing of therapies modulating chemokine signaling
07

Biomarkers

CCL22 protein levels may serve as biomarkers for inflammatory diseases, cancer progression, and immune status in certain therapeutic contexts
