Depression and cognitive disorders, complex diseases with unknown causes, have seen an increase in prevalence due to the COVID-19 pandemic. Inadequate current treatments necessitate the search for new compounds to effectively alleviate symptoms and treat cognitive decline. Sigma-1 receptors, multifunctional proteins localized in endoplasmic reticulum membranes, have emerged as potential drug targets for these conditions. Modulating sigma-1 receptors may hold therapeutic potential for central nervous system diseases such as depression and memory impairments.
Depression and cognitive disorders are diseases with complex and not-fully understood etiology. Unfortunately, the COVID-19 pandemic dramatically increased the prevalence of both conditions. Since the current treatments are inadequate in many patients, there is a constant need for discovering new compounds, which will be more effective in ameliorating depressive symptoms and treating cognitive decline. Proteins attracting much attention as potential targets for drugs treating these conditions are sigma-1 receptors. Sigma-1 receptors are multifunctional proteins localized in endoplasmic reticulum membranes, which play a crucial role in cellular signal transduction by interacting with receptors, ion channels, lipids, and kinases. Changes in their functions and expression may lead to various diseases, including depression or memory impairments. Thus, sigma-1 receptor modulation might be useful in treating these central nervous system diseases. Importantly, two sigma-1 receptor ligands entered clinical trials, showing that this compound group possesses therapeutic potential. Therefore, based on preclinical studies, this review discusses whether the sigma-1 receptor could be a promising target for drugs treating affective and cognitive disorders.
