Background and Aims: TGF-β is an effective cytokine in the viral replication cycle, which is also highly relevant to the pathogenesis of some viral infections. TGF-β induction by viral proteins is one of the ways to escape the virus from the immune system by inhibiting interferon signaling and other immune system factors.  In recent years, the role of TGF-β and its inhibitor...

introduction: 17&beta-estradiol; modulates nociception by binding to the estrogenic receptors and also by allosteric interaction with other membrane-bound receptors like glutamate and gabaa receptors. in addition to its autonomic functions, paragigantocellularis lateralis (lpgi) is involved in the pain modulation, too. the aim of the current study was to investigate the involvement of the membr...

neurological inflammatory diseases are developing rapidly. different factors involved in the pathogenesis of these diseases. in this article, we discuss some of the mechanisms are dealt with. an aberrant procedure of beta-amyloid precursor protein (bapp) to form neurotoxic beta-amyloid peptides and an accumulated insoluble polymer of beta –amyloid (ba) that forms the senile plaque. the above pr...

BACKGROUND AND PURPOSE beta-Arrestins are critical scaffold proteins that shape spatiotemporal signalling from seven transmembrane domain receptors (7TMRs). Here, we study the association between neuropeptide Y (NPY) receptors and beta-arrestin2, using bimolecular fluorescence complementation (BiFC) to directly report underlying protein-protein interactions. EXPERIMENTAL APPROACH Y1 receptors...

Alzheimer’s disease is a common neurodegenerative disease. Microglia induces oxidative stress in the brain for engulfing bacteria and viruses. The accumulating data indicate that apoptosis are two main actors induction of microglia activation-induced Disease. Oxidative one many triggers activate transient receptor potential melastatin 2 (TRPM2) channel. Glutathione (GSH) cytosolic antioxidant m...

Background and Aim: High blood pressure is a common cardiovascular disease. Most cardiovascular medications have adverse oral side effects. This study aimed to determine the prevalence of oral manifestations associated with the intake of anti-hypertensive medications. Materials and Methods: This cross-sectional analytical study examined 142 patients with a history of hypertension referred to D...

The effects of epidermal growth factor (EGF) on the beta-adrenergic receptor-coupled adenylyl cyclase system were studied in a human salivary cell line (HSY). The beta-adrenergic agonist isoproterenol (10(-5) M) stimulated adenylyl cyclase activity by approximately 2-fold, and the isoproterenol response was increased 1.8-fold after prolonged (48 h) exposure to EGF (5 x 10(-10) M). In contrast, ...

Propranolol is a nonselective beta-adrenergic receptor blocking agent possessing no other autonomic nervous system activity. It specifically competes with beta-adrenergic receptor agonist agents for available receptor sites. When access to beta-receptor sites is blocked by propranolol, the chronotropic, inotropic, and vasodilator responses to beta-adrenergic stimulation are decreased proportion...

OBJECTIVE Significant cardiac dysfunction after brain death leading to exclusion from procurement for cardiac transplantation is seen in up to 25% of potential organ donors in the absence of structural heart disease. The cause includes uncoupling of the myocardial beta-adrenergic receptor signaling system. The mechanism, however, has not yet been described. This study investigates our hypothesi...
