Effect of Epigallocatechin Gallate and Catechin on Overexpression of GSK-3β and IR Genes Induced by Streptozotocin in Rat Brain

Background: Type 2 diabetes mellitus (T2DM) is one of the significant risk factors for Alzheimer disease (AD). Defects in insulin signaling pathway induce AD hallmarks mainly through activation of glycogen synthase kinase-3β (GSK-3β) pathway.  Objectives: In this study, we investigated the expression of GSK-3β and insulin receptor (IR) genes in the hippocampi of an animal model of sporadic AD ...

The COVID-19 Pandemic: Is It A Wolf Consuming Fertility?

The Effect of Swimming Endurance Exercise on Cell Death and Nicotinic Acetylcholine Receptor Gene Expression in Brain of Rat: An Experimental Study of Alzheimer's Disease Model

Background and Objectives: Alzheimerchr('39')s disease (AD) is a neurodegenerative disease which is marked by impaired cholinergic function and decreased nicotinic acetylcholine receptor (nAChRs) density. nAChRs are important mediators of cholinergic signaling in modulation of learning and memory function. In Alzheimer hippocampus is particularly vulnerable to specific degenerative processes an...

Effects of sex steroid hormones on neuromedin S and neuromedin U2 receptor expression following experimental traumatic brain injury

Objective(s): Neuroprotective effects of female gonadal steroids are mediated through several pathways involving multiple peptides and receptors after traumatic brain injury (TBI). Two of these peptides are including the regulatory peptides neuromedin U (NMU) and neuromedin S (NMS), and their common receptor neuromedin U2 receptor (NMUR2). This study investigates the effects of physiological do...

Haloperidol’s Effect on the Expressions of TGFB, NT-3, and BDNF genes in Cultured Rat Microglia

Introduction: Microglia, small glial cells, i.e. mesodermal in origin and found in the brain and spinal cord, play a key role in the maintenance of neurons and immune defense. Haloperidol, an antipsychotic drug, is used to treat numerous neurological and neurodegenerative disorders. Its mechanism is not understood; however, haloperidol may result in Wnt signaling pathway activation. This study ...
