[Recent progress in the pathophysiological role of interleukin-19]

Area of Science:

• Immunology
• Molecular Biology
• Cell Biology

Background:

• Cytokine signaling is crucial for biological functions, immune homeostasis, and disease progression.
• Pro-inflammatory cytokines drive immunological diseases, making them therapeutic targets.
• Anti-inflammatory cytokines, like IL-10, suppress inflammation and aid tissue repair.

Purpose of the Study:

• To review recent research on Interleukin-19 (IL-19).
• To elucidate the pathophysiological role of IL-19 in inflammatory diseases.
• To explore the therapeutic potential of IL-19 in managing inflammatory conditions.

Main Methods:

• Literature review of recent studies on IL-19.
• Analysis of IL-19's involvement in Th17 responses and related diseases.
• Examination of IL-19's anti-inflammatory effects in various disease models.

Main Results:

• IL-19, a member of the IL-10 family, is produced by myeloid and epithelial cells.
• IL-19 can upregulate Th17 responses, contributing to diseases like psoriasis.
• IL-19 demonstrates anti-inflammatory effects in infectious skin, inflammatory bowel, and cardiovascular diseases.

Conclusions:

• IL-19 exhibits pleiotropic effects in inflammatory diseases, dependent on the specific pathological context.
• Understanding IL-19's dual role is critical for developing targeted therapies.
• Further research is warranted to fully harness IL-19's therapeutic potential.
