Mast Cells as a Potential Target of Molecular Hydrogen in Regulating the Local Tissue Microenvironment

Dmitri Atiakshin et al. Pharmaceuticals (Basel). .

Abstract

Knowledge of the biological effects of molecular hydrogen (H2), hydrogen gas, is constantly advancing, giving a reason for the optimism in several healthcare practitioners regarding the management of multiple diseases, including socially significant ones (malignant neoplasms, diabetes mellitus, viral hepatitis, mental and behavioral disorders). However, mechanisms underlying the biological effects of H2 are still being actively debated. In this review, we focus on mast cells as a potential target for H2 at the specific tissue microenvironment level. H2 regulates the processing of pro-inflammatory components of the mast cell secretome and their entry into the extracellular matrix; this can significantly affect the capacity of the integrated-buffer metabolism and the structure of the immune landscape of the local tissue microenvironment. The analysis performed highlights several potential mechanisms for developing the biological effects of H2 and offers great opportunities for translating the obtained findings into clinical practice.

Keywords: inflammation; local tissue microenvironment; mast cells; molecular hydrogen; reactive oxygen intermediates; secretome; specific mast cell proteases.

Targets for Mast Cell Secretome Components in a Specific Tissue Microenvironment. The figure shows the main targets of the specific tissue microenvironment for mast cells, including non-immune cells, immunocompetent cells and extracellular matrix targets. The arsenal of biologically active substances of MC for secretion is represented by a wide range of preformed, neoformed and neosynthesized mediators, which allows for the highly selective regulation of the state of cellular and extracellular targets within the determined physiological constants. Thus, by influencing the biosynthetic and secretory activities of mast cells, molecular hydrogen is able to indirectly regulate the key parameters of the local microenvironment within limited tissue compartments and niches.
