Abstract

Background

The human intestine is continuously exposed to a variety of aggressive agents, including food antigens, xenobiotics, numerous pathogenic microorganisms, metabolic products, and toxins. Consequently, it has developed a specialized system for protection against these adverse factors.

Objective

This study aims to investigate the biochemical compounds synthesized by Paneth cells and their mechanisms of action to develop new therapeutic approaches for gastroenterological diseases.

Methods

We conducted a systematic review, excluding a comprehensive meta-analysis, of the current scientific literature sourced from electronic libraries (CyberLeninka, e-Library.ru, and Cochrane Library), search engines (Google Scholar, Embase, and Global Health), and scientific databases (Elsevier, Medline, PubMed-NCBI, eMedicine, the National Library of Medicine (NLM), and ReleMed and Scopus). Following PRISMA guidelines, a total of 104 articles were initially selected based on defined inclusion and exclusion criteria. After careful evaluation, 63 articles were included in this study.

Results

Our findings indicate that Paneth cells play a crucial role in regulating small intestine homeostasis by secreting numerous biologically active molecules. A key feature of these cells is their ability to recognize soluble microbial products pattern recognition receptors and respond by releasing a variety of antimicrobial peptides and enzymes. These secretions contribute to the formation of a biochemical barrier that prevents pathogen adhesion and translocation. Paneth cells are integral to immunological protection, maintaining protective inflammatory responses under both normal and pathological conditions. Additionally, they regulate the division, growth, and differentiation of intestinal stem cells, ensuring proper enterocyte localization. Paneth cells also aid digestive processes through enzyme secretion and are the only epithelial cells capable of eliminating activated autoreactive lymphocytes and abnormal enterocytes.

Conclusion

Paneth cells are unique epithelial cells that, through the synthesis of numerous biologically active molecules, control the timely regeneration of the intestinal epithelium, maintain a healthy microbiota, and prevent infectious, autoimmune, and cancerous diseases. Understanding their role in these processes is crucial for developing new therapies for gastroenterological diseases.
