چکیده

Opioids like morphine have been widely used clinicaly as effective analgesics for acute and chronic pain. When opioids are used, the importance of care for side effects such as nausea, drowsiness and constipation is emphasized. In addition, continuous use of opioids developes tolerance in which the analgesic effect becomes attenuated. In this paper, we mainly discuss endoplasmic reticulum (ER) stress as one of the molecular mechanisms for the development of opioid tolerance.

Endoplasmic reticulum stress regulates inflammation in adipocyte of obese rats via toll-like receptors 4 signaling

Objective(s): To explore whether endoplasmic reticulum (ER) stress regulates inflammation in adipose tissue of obese rats via TLR4 signaling. Materials and Methods: Sprague Dawley rats were randomly divided into four groups, and body weight, food intake, and free fatty acids (FFA) were measured. Real-time PCR and Western blot were used to determine mRNA or protein expression of TLR4, TRAF6, IKK...

Gating Behavior of Endoplasmic Reticulum Potassium Channels of Rat Hepatocytes in Diabetes

Background: Defects in endoplasmic reticulum homeostasis are common occurrences in different diseases, such as diabetes, in which the function of endoplasmic reticulum is disrupted. It is now well established that ion channels of endoplasmic reticulum membrane have a critical role in endoplasmic reticulum luminal homeostasis. Our previous studies showed the presence of an ATP-sensitive cationic...

Allantoin improves methionine-choline deficient diet-induced nonalcoholic steatohepatitis in mice through involvement in endoplasmic reticulum stress and hepatocytes apoptosis-related genes expressions

Objective(s): Non-alcoholic steatohepatitis (NASH) is defined by steatosis and inflammation in the hepatocytes, which can progress to cirrhosis and possibly hepatocellular carcinoma. However, current treatments are not entirely effective. Allantoin is one of the principal compounds in many plants and an imidazoline I receptor agonist as well. Allantoin has positive eff...

Zanthoxylum Alatum Attenuates Chronic Restraint Stress Adverse Behavioral Effects Via the Mitigation of Oxidative Stress and Modulating the Expression of Genes Involved in Endoplasmic Reticulum Stress in Mice

Introduction: The functions of the endoplasmic reticulum (ER) are important, particularly in the proteins’ synthesis, folding, modification, and transport. Based on traditional medicine and our previous studies on Zanthoxylum alatum in lipopolysaccharide-induced depressive behavior and scopolamine-induced impaired memory, the present study explored the role of hydroalcoholic extract of Z. alatu...

The pathology propagates to neighboring cerebral regions through a prion-likemechanism. In AD, intracellular calcium dyshomeostasis is associated with endoplasmicreticulum (ER) stress. This study was designed to examine hippocampal ER stre...
