Gene and cell therapy of adrenal pathology: achievements and prospects

Our current understanding of the molecular and cellular mechanisms in tissues and organs during normal and pathological conditions opens up substantial prospects for the development of novel approaches to treatment of various diseases. For instance, lifelong replacement therapy is no longer mandatory for the management of some monogenic hereditary diseases. Genome editing techniques that have emerged in the last decade are being actively investigated as tools for correcting mutations in affected organs. Furthermore, new protocols for obtaining various types of human and animal cells and cellular systems are evolving, increasingly reflecting the real structures in vivo. These methods, together with the accompanying gene and cell therapy, are being actively developed and several approaches are already undergoing clinical trials. Adrenal insufficiency caused by a variety of factors can potentially be the target of such therapeutic strategies. The adrenal gland is a highly organized organ, with multiple structural components interacting with each other via a complex network of endocrine and paracrine signals. This review summarizes the findings of studies in the field of structural organization and functioning of the adrenal gland at the molecular level, as well as the modern approaches to the treatment of adrenal pathologies.
