Paneth cells in farm animals: current status and future direction.

Area of Science:

• Veterinary Science
• Cell Biology
• Animal Science

Background:

• Paneth cells in the small intestine regulate intestinal microbiota and intestinal stem cells (ISCs).
• While extensively studied in humans and mice, Paneth cells in farm animals remain under-investigated.
• These cells are vital for overall farm animal growth and development.

Purpose of the Study:

• To review the current knowledge on Paneth cells in various livestock species.
• To highlight differences in Paneth cell morphology and distribution across species.
• To identify future research directions for improving intestinal health in farm animals.

Main Methods:

• Literature review of studies on Paneth cells in pig, cattle, sheep, horse, chicken, and rabbit.
• Analysis of identification methods, morphological characteristics, and functional roles.
• Comparative assessment of Paneth cell features across different livestock.

Main Results:

• Paneth cells are present in the small intestine of most farm animals, identified via various staining techniques.
• Significant variations exist in Paneth cell shape, granule content, and distribution among livestock species.
• Factors like diet and infection impact Paneth cells and their antimicrobial peptides (AMPs).

Conclusions:

• A comprehensive understanding of Paneth cells in diverse farm animals is essential for enhancing intestinal health.
• Further research is needed to elucidate species-specific functions and responses.
• This knowledge can guide strategies for improved livestock health and productivity.
