Neuroscientists seek Parkinson's, addiction insights by tracking gene expression

(Picower Institute at MIT) Two MIT neuroscientists have received grants from the G. Harold and Leila Y. Mathers Foundation to screen for genes that could help brain cells withstand Parkinson's disease and to map how gene expression changes in the brain in response to drugs of abuse.

Conclusions. Compound 14b exhibited high affinity and excellent subtype selectivity, which was then evaluated by in vitro autoradiography and in vivo PET imaging study after labeling with carbon-11. Ligand [11C]14b, which we named [11C]MG2-1904, demonstrated high brain uptake and excellent in vitro/in vivo specific binding towards mGlu2 with high metabolic stability in the brain. As proof-of-concept, our preliminary work demonstrated a successful example of visualizing mGlu2 in vivo derived from NAMs, which represents a promising chemotype for further development and optimization aimed for clinical translation.

;re P Abstract Nearly 100 years after the discovery of serotonin, its role remains elusive. The Special Issue Serotonin Research: crossing scales and boundaries presented here in Neuropharmacology covers the diversity and complexity of the serotonin system with its many receptor subtypes. This collection is made up of a selection of nine review articles and 16 research articles. Modulation of serotonin transmission is considered in numerous central nervous system (CNS) diseases including depression, anxiety, schizophrenia, obsessive-compulsive disorders, addiction, Parkinson's disease, and Alzheimer's disease. The...

Forebrain dopaminoceptive neurons play a key role in movement, action selection, and motivation, and are dysregulated in addiction, Parkinson ’s disease, and many other medical conditions. To investigate similarities and differences between the main types of dopamine-sensitive neurons we compared the full ensemble of translated mRNAs in neurons expressin...

CONCLUSION: The dopamine D1-D2 heteromer is expressed in key brain cortical and subcortical regions of all species examined. Species differences in striatum revealed greater abundance in human>nonhuman-primate>rat>mouse, suggesting an evolutionary biologic role for the D1-D2 heteromer in higher CNS function. Its upregulation in rat striatum following cocaine points to regulatory significance with possible relevance for clinical disorders such as drug addiction. The dopamine D1-D2 receptor heteromer may represent a potential target for neuropsychiatric and neurodegenerative disorders, given its distribution in high...

  Cannabis, weed, marijuana, pot. It goes by several names, but we all know what it smells like. As weed becomes more mainstream, we on the Not Crazy podcast want to know: Is marijuana really an effective treatment for anxiety? Is it just a coping mechanism? Or a vice? In today’s podcast, Gabe and Jackie look at the research and weigh out the evidence. They also interview Eileen Davidson, a rheumatoid arthritis patient who regularly uses marijuana as a medicine to see what she has to say. What’s your take? Tune in for an open-minded discussion about weed. (Transcript Available Below) SUBSCRIBE &REV...

Chronic pain is an enigma for both pain doctors and their patients: difficult to understand (as everyone’s pain is different), challenging to treat effectively, and frustrating to live with. Desperate patients sometimes turn to drastic and irreversible surgical procedures, like amputating nerves to relieve pain, and unfortunately even those procedures may fail to provide the hoped-for results. Fortunately there have been great strides in research related to pain perception and our nervous system’s reaction to various pain treatments, and we’ve been able to develop novel devices that provide many people wi...

(Texas Tech University Health Sciences Center) Serotonin type 3A is a member of the protein superfamily known as pentameric ligand-gated ion channels. When these channels don't function properly, these proteins have been linked to Alzheimer's disease, Parkinson's disease, epilepsy, schizophrenia, alcohol addiction and myasthenia gravis. Michaela Jansen, Pharm.D., Ph.D., from the Texas Tech University Health Sciences Center recently completed a study that provides novel insights into a protein-protein interaction that could lead to more effective treatments for these disorders.

In this study, manganese-enhanced magnetic resonance imaging (MEMRI) was used to map the accumulative whole-brain activities associated with a 7-day EE exposure in freely-moving adult male mice, followed by c-Fos immunochemical assessments. Relative to the mice residing in a standard environment (SE), the mice subjected to EE treatment had significantly enhanced regional MEMRI signal intensities in the prefrontal cortex, somatosensory cortices, basal ganglia, amygdala, motor thalamus, lateral hypothalamus, ventral hippocampus and midbrain dopaminergic areas at the end of the 7-day exposure, likely attributing to enhanced M...
