A study of the diagnostic value of tissue eosinophil infiltration in the structure of polyps of the human gastrointestinal tract and surrounding tissues was carried out. We investigated intestinal biopsies from 189 patients aged 40–90 years with polyps, cancer, metastases. This retrospective study allows us to note the possibility of using eosinophils in the development of criteria for early malignancy and a promising outcome of neoplasms in the mucous membrane. Eosinophils are important players in intercellular interactions within the polyp structure and the tissues around it. The complete absence of eosinophils in the tissue of malignant polyps indicates the malignancy of the neoplasm. We revealed relationship between apoptosis and eosinophilic infiltration; both of them affect the outcome and prognosis of polyp development. Apoptosis induction by eosinophils and programmed cambium necrosis in tumor progression need to be further researched.

The human gastrointestinal tract is more complex in its structure and volume of its functions, an organ, or rather, a system of organs. In addition, the intestinal microbiota, which, in turn, is part of the brain-intestine-microbiota axis, is also included in the process of implementing the tasks of the gastrointestinal tract. In this regard, not only instrumental, such as radio-radiological, ultrasound, endoscopic (with subsequent study of biopsy material) and other research methods are relevant, but also laboratory ones aimed at obtaining information about the microbiome and signal molecules involved in regulatory processes gastrointestinal tract. This literature review is devoted to the analysis of modern research methods for neurotransmitters synthesized by the digestive tract and of diagnostic value.
