Melatonin signaling in T cells: Functions and applications

Area of Science:

• Immunology
• Endocrinology
• Cell Biology

Background:

• Melatonin influences critical physiological processes, including immune function.
• T-cell-mediated immunity is vital for defense against infections and cancer, yet implicated in autoimmune diseases.
• Understanding melatonin's role in T-cell biology is crucial for managing immune-related conditions.

Purpose of the Study:

• To review the significance of melatonin in T-cell biology.
• To explore the beneficial effects of melatonin in T-cell response-based diseases.
• To elucidate the mechanisms underlying melatonin's influence on T cells.

Main Methods:

• Review of existing literature on melatonin and T-cell interactions.
• Analysis of melatonin's effects on T-cell activation, differentiation, and signaling pathways.
• Examination of melatonin's therapeutic potential in T-cell-mediated inflammatory diseases.

Main Results:

• T cells synthesize and respond to melatonin via membrane and nuclear receptors, as well as receptor-independent pathways.
• Melatonin effectively modulates T-cell subsets, including Th17, Treg, and memory T cells.
• Signaling pathways like ERK1/2-C/EBPα are involved in melatonin's regulatory roles.
• Melatonin demonstrates beneficial effects in inflammatory diseases such as type 1 diabetes, lupus, and multiple sclerosis.

Conclusions:

• Melatonin signaling is integral to T-cell fate determination and immune pathology.
• Melatonin holds therapeutic promise for various T-cell-driven inflammatory and autoimmune conditions.
• Further research into melatonin's mechanisms can unlock new treatment strategies for immune disorders.
