This mini-review focuses on the studies of late Prof. IP Lapin (1903 – 2012) and his research team on the role of methoxyindole and kynurenine (KYN) pathways of tryptophan (TRP) metabolism in the pathogenesis of depression and action mechanisms of antidepressant effect. In the late 60s of the last century Prof. IP Lapin suggested that “intensification of central serotoninergic processes is a determinant of the thymoleptic ( Read More

A large amount of the data gathered in the last 50 years support the hypothesis that alterations of the serotonin (5-HT) neurotransmission play a crucial role in the pathophysiology of not only major depression (MD), but also of different neuropsychiatric disorders. Research in this field has been substantially promoted by the evidence that the reuptake protein (SERT), present in presynaptic neurons, is a key element in termi Read More

Major depression (MD) is a major health problem, partly due to the incomplete understanding of the pathogenic mechanisms of the disease. Research efforts have mainly focused on alterations in monoaminergic neurotransmission, especially in relation to the serotonergic system, due to its key role in the regulation of mood and related biological functions. Given the high heritability of MD (estimated between 31% and 42 Read More

Disorders of emotion regulation such as anxiety disorders and depression are common and yet debilitating. Accumulating evidence suggests involvement of serotonin (5-HT) in the regulation of emotion. Mice with targeted deletion of genes encoding mediators of the serotonergic transmission have proven to be a powerful tool for understanding contributions of such mediators of emotion regulation. Over the last d Read More

The current generation of antidepressant drugs acts predominantly by targeting the serotonin transporter (SERT). The original trend to do this selectively (e.g., with SSRIs or selective serotonin reuptake inhibitors) has given way to combining various additional pharmacologic mechanisms with SERT inhibition, including dual actions by single drugs (e.g., SNRIs or serotonin norepinephrine reuptake inhibitors), or by augmentin Read More

The critical role of mitochondria in cardiomyocyte survival and death has become an exciting field of research in cardiac biology. Indeed, it is accepted that mitochondrial dysfunction plays a crucial role in the pathogenesis of multiple cardiac diseases. Besides the obvious relevance of mitochondria in energy production, calcium homeostasis, and reactive oxygen species (ROS) production, new processes like mitochondri Read More

Helicobacter species colonizes the stomach and are associated with the development of gastritis disease. Drugs for treatment of Helicobacter infection relieve pain or gastritis symptoms but they are not targeted specifically to Helicobacter pylori. Therefore, there is dire need for discovery of new drug targets and drugs for the treatment of H. pylori. The main objective of this study is to screen the potential drug targets by i Read More

Keratins are naturally derived proteins that can be fabricated into several biomaterials morphologies including films, sponges and hydrogels. As a physical matrix, keratin biomaterials have several advantages of both natural and synthetic materials that are useful in tissue engineering and controlled released applications. Like other naturally derived protein biomaterials, such as collagen, keratin possess amino acid sequenc Read More
