The CD83 Molecule - An Important Immune Checkpoint

Area of Science:

• Immunology
• Molecular Biology

Background:

• CD83 molecule is expressed on various activated immune cells like B and T lymphocytes, monocytes, dendritic cells, microglia, and neutrophils.
• Both membrane-bound and soluble CD83 isoforms are subjects of extensive research.
• CD83 is recognized for its critical role in immune response regulation and tolerance, rather than co-stimulation.

Purpose of the Study:

• To present the latest findings on CD83 expression, structure, and signaling partners.
• To review the regulatory functions of CD83 in maintaining immune balance.
• To highlight the therapeutic potential of CD83 in preclinical models.

Main Methods:

• Review of existing literature and recent research data.
• Analysis of CD83 expression patterns across different immune cells.
• Investigation into CD83's interaction partners and signaling pathways.

Main Results:

• CD83 plays a crucial role in controlling and resolving immune responses.
• It is essential for T and B lymphocyte differentiation and immune tolerance.
• Recent data sheds light on CD83's structure, signaling, and interaction partners.

Conclusions:

• CD83 exhibits significant immunomodulatory potential, balancing tolerance and inflammation.
• Its properties suggest considerable therapeutic applications in various pathological conditions.
• Further research into CD83's mechanisms can unlock new treatment strategies.
