Infectious diseases caused by viruses have become a serious public health issue in the recent past, including the current pandemic situation of COVID-19. Enveloped viruses are most commonly known to cause emerging and recurring infectious diseases. Viral and cell membrane fusion is the major key event in the case of enveloped viruses that is required for their entry into the cell. Viral fusion proteins play an important r Read More

Background: The neuroinflammatory process is associated with the pathogenesis of many cardiovascular disorders, particularly with hypertension. In this regard, the deficiency of vitamin D seems to increase the risk of cardiovascular pathologies related to neuroinflammation. Long-term lack of vitamin D leads to over-activation of the renin-angiotensin-aldosterone system (RAAS), one of the essential mechanisms of blood pressu Read More

Ghrelin is a 28-amino acid octanoylated peptide hormone that is implicated in many physiological and pathophysiological processes. Specific visualization of ghrelin and its cognate receptor using traceable ligands is crucial in elucidating the localization, functions, and expression pattern of the peptide’s signaling pathway. Here 12 representative radio- and fluorescently-labeled peptide-based ligands are reviewed for in vitro Read More

Locating remedies for Alzheimer’s disease (AD) has been majorly restricted by the inefficiency to establish a definitive detection model for early-stage diagnosis of pathological events. This current lapse in AD diagnosis also limits the therapeutic efficiency of the drugs, which might have been effective if given at the earlier stages of the disease. The indicated situation directs towards the burgeoned need for an effective biomar Read More

Serotonin (5-hydroxytryptamine, 5-HT) has been recognized as a potent pro-inflammatory mediator. Increasing the bioavailability and preventing the formation of 5-HT can reduce the inflammatory response in the body. Moreover, 5-HT is considered as an important central physiologic mediator of intestinal function by regulating intestinal motility, permeability, and other functions. The dysfunction of intestinal serotoner Read More

Transient receptor potential melastatin 7 (TRPM7), along with the closely related TRPM6, are unique channels that have dual operations: cation permeability and kinase activity. In contrast to the limited tissue distribution of TRPM6, TRPM7 is widely expressed among tissues and is therefore implicated in a variety of cellular functions physiologically and pathophysiologically. The discovery of TRPM7’s unique structure imparting Read More

Ligand-linked changes in the aggregation state of biological macromolecules occur and have importance in several physiological processes, e.g., the response of hormone receptors, cooperative ligand binding, and others. The mathematical formalisms that express the thermodynamics governing these processes are complex, as they are required to describe observations made under experimental conditions in which m Read More

Aminoglycosides and β-lactams are the most commonly used antimicrobial agents in clinical practice. This occurs because they are capable of acting in the treatment of acute bacterial infections. However, the effectiveness of antibiotics has been constantly threatened due to bacterial pathogens producing resistance enzymes. Among them, the aminoglycoside-modifying enzymes (AMEs) and β-lactamase enzymes are t Read More

Indoleamine 2, 3-dioxygenase 1 (IDO1) is the only rate-limiting enzyme outside the liver that catalyzes the oxidation and cracking of indole rings in the tryptophan along the kynurenine pathway (KP). The overactivation of IDO1 is closely related to the pathogenesis of various human immune and neurological diseases. As an important target for the treatment of many human serious diseases, including malignant tumors, the devel Read More
