DREADDs are chemogenetic tools widely used to remotely control cellular signaling, neuronal activity, and behavior. Here we used a structure-based approach to develop a new Gi-coupled DREADD using the kappa-opioid receptor as a template (KORD) that is activated by the pharmacologically inert ligand salvinorin B (SALB). Activation of virally expressed KORD in several neuronal contexts robustly a...
INTRODUCTION Drug overuse is a serious problem for health care, and one of the biggest problems for the socio-economic well-being of different communities. The elderly tend to use more drugs due to changes in their cognitive and physiological factors. One of the best ways to evaluate the health level of elderly people is to evaluate their self-medication. This study was conducted to investigate...
In this issue of Neuron, innovative new modifications to opioid receptors are used to expand the tools available to modulate neuronal activity. Vardy et al. (2015) describe a new "DREADD" chemogenetic tool based on the inhibitory κ opioid receptor (KORD) that can be used in conjunction with already-available DREADDs. Siuda et al. (2015) report the development of "opto-MOR," a light-activatable ...
UNLABELLED In many human alcoholics, abstinence is self-imposed because of the negative consequences of excessive alcohol use, and relapse is often triggered by exposure to environmental contexts associated with prior alcohol drinking. We recently developed a rat model of this human condition in which we train alcohol-preferring P rats to self-administer alcohol in one context (A), punish the a...
This study was conducted in 2004 to evaluate the prevalence of hepatitis B (HBV), hepatitis C (HBC) and human immunodeficiency (HIV) virus infection in 133 injecting drug users (IDUs) attending a voluntary rehabilitation centre in Shahr-e-Kord, and to identify risk factors for these infections in this group. Serum samples were screened for HBV, HCV and HIV infection. Only 1 participant (0.8%) w...
