Application of GSDMD inhibitor in preparation of medicine for treating helicobacter pylori infection

Abstract

The invention relates to the technical field of biological medicines, in particular relates to application of a GSDMD inhibitor in preparation of a medicine for treating helicobacter pylori infection,and aims to solve the problem that a death signalling pathway of neutrophile granulocyte after helicobacter pylori infection, in particular change of pyroptosis molecular mechanism, is unclear in theprior art. After the signalling pathway is definite, the condition that stomach helicobacter pylori infection can be treated by utilization of the GSDMD inhibitor can be prompted; the pyroptosis process of the neutrophile granulocyte infiltrated at the infection part is inhibited; therefore, the clinical existing antibacterial medicine combined therapy is replaced; and generation of the medicinetolerance is reduced.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to the application of GSDMD inhibitors in the preparation of medicines for treating Helicobacter pylori infection. Background technique [0002] Helicobacter pylori (H. pylori) is a class I carcinogen, and infection with H. pylori can cause various diseases such as gastroduodenal inflammation. For some patients, the efficacy of H.pylori clinical drug eradication is not satisfactory. Neutrophils are an important component of the body's innate immune system and play an important role in the body's defense against the invasion of pathogenic microorganisms. Studying the mechanism of H.pylori-induced neutrophil death disorder can reveal the role of neutrophils in the body's anti-infection immunity, which is of great significance for the prevention and treatment of related diseases caused by H.pylori. [0003] Pyroptosis is a kind of cell lytic death that relies on inflammatory casp...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides the application of GSDMD inhibitor in the preparation of medicine for treating Helicobacter pylori infection, especially the application of GSDMD inhibitor in the preparation of neutrophil infiltration target medicine of Helicobacter pylori infection, aiming to solve the unclear The death signaling pathway of neutrophils after Helicobacter pylori infection, especially the change of the molecular mechanism of pyroptosis; after clarifying the signaling pathway, it is suggested that GSDMD inhibitor (necrosulfonamide) can be used to treat Helicobacter pylori infection in the stomach and inhibit the infection site The pyroptotic process of infiltrating neutrophils can replace the combination therapy of antibacterial drugs currently used in clinical practice, reduce the generation of drug resistance, and solve the problems existing in the prior art
