Summary: We studied the expression of serotonin receptors 5-HT1A, 5-HT2A, and 5-HT3A at different stages of fetal lung development. The receptors were strongly expressed in the epithelium of the proximal airways and vascular walls during early and mid-fetal development. In the later stages, they were also expressed in type I and type II pneumocytes. The expression of 5-HT2A decreased while 5-HT3A expression increased toward the final stage of lung development.

Summary: Serotonin controls human cardiac contractile function solely through 5-HT4-receptors, leading to positive inotropic and chronotropic effects, as well as arrhythmias. This review focuses on the potential effects of 5-HT4-receptors in sepsis, ischemia, and reperfusion. The formation and inactivation of serotonin in the heart, as well as its role in cardiovascular diseases, are discussed. Mechanisms of cardiac signal transduction through 5-HT4-receptors and potential roles in cardiac diseases are addressed, along with future research directions and potential animal models. The potential clinical utility of 5-HT4-receptor agonists or antagonists is also discussed, considering the extensive studies on serotonin over the years.

Summary: This study investigated the effects of lurasidone, vortioxetine, and escitalopram on 5-HT7R function and found that chronic administration of these drugs leads to downregulation of 5-HT7R in the thalamus. Furthermore, it was observed that vortioxetine and lurasidone induce more rapid downregulation of 5-HT7R through direct inhibition, while escitalopram's downregulation is slower due to its indirect elevation of extracellular serotonin levels.

Summary: The metabolism of serotonin is closely linked to tumorigenesis and tumor progression, with studies showing its role in regulating various biological processes of tumors. Reprogramming of 5-HT metabolism in different types of tumors has paved the way for new approaches in developing cancer therapies targeting this pathway. Information on the role of 5-HT metabolism in cancer is limited, but recent advances have shed light on potential targeted therapies.

Summary: The activation of 5-HT1D and 5-HT7 receptors plays a role in mechanical allodynia induced by 5-HT in mice, while peripheral 5-HT3 receptors have an inhibitory role in the nociceptive response induced by 5-HT or carrageenan.

Summary: This article reviews the neurobiological links between aggression, depression, and suicidal behavior, focusing on the involvement of different types of 5-HT receptors. It provides evidence that specific 5-HT receptors are associated with depression-related and aggression-related behaviors, and highlights the potential of targeting these receptors for treatment.

Summary: Serotonin, also known as 5-hydroxytryptamine (5-HT), is a crucial neurotransmitter synthesized and secreted by enterochromaffin (EC) cells in the gastrointestinal tract. Gut microbiota, nutrients, and hormones play key roles in regulating 5-HT secretion. Understanding the regulatory mechanisms of 5-HT in the immune system can potentially provide therapeutic strategies for treating intestinal diseases.

Summary: This study investigates the localization of serotonin and 5-HT7 type serotonin receptors in larvae of parasitic flatworms using immunocytochemical methods and confocal laser scanning microscopy. The results indicate the presence of 5-HT7 immunoreactivity in specific structures of the worms, suggesting its importance in the motor control system of flatworms.

Summary: Derivatives of (N)-Methanocarba adenosine were modified to target 5-HT2B serotonin receptors as antagonists, showing affinity enhancement with the bicyclic ring system. Compound 43 (MRS7925) exhibited potential for anti-fibrotic therapy due to its affinity and moderate 5-HT2BR binding selectivity. The compounds also demonstrated dual action as 5-HT2B antagonists and A(1)AR agonists.

Summary: Various forms of TBI are a leading cause of disability in the US, with the generation of neuropsychiatric complications such as depression and anxiety. This study found that mild TBI can lead to selective alterations in cortical 5-HT2A receptor signaling, which may be targeted for the development of pharmacotherapies to alleviate TBI-induced neuropsychiatric disorders.

Summary: Psilocybin has shown promising rapid and persistent antidepressant effects in mice, possibly through enhancing excitatory synapses in the hippocampus, independent of 5-HT2A receptor activation. Further research is needed to explore the potential combination of psychedelic compounds and 5-HT2AR antagonists for clinical utility in human depression.

Summary: The aim of our study was to evaluate the differences among different groups of drug users, focusing on hematological, biochemical, urinary, and cardiological aspects. A retrospective study was conducted on 2572 hospitalized patients in Bucharest, Romania from 2015 to 2021. The study group was characterized based on demographic data, personal history/co-morbidities, consumption history, and substitution treatment. The analysis of medical records revealed correlations between GGT levels and alcohol intake as well as contagious diseases, a decrease in MCH and MCHC levels across the entire study group, and correlations between specific cardiological events and certain substance groups. The study provides important information on different types of drug users and supports future research on the chemical structures of consumed compounds.
