Sex Differences And Neuroimmune Effects Of Microglial Response In The Mesolimbic Reward Pathway In Nicotine Substance Use Disorder, Erin Leigh Anderson

Smoking remains the leading cause of morbidity and mortality in the United States, with less than 5% of smokers attempting to quit succeeding. This is due to the unpleasant withdrawal symptomology, which includes affective symptoms, such as irritability, weight gain, anxiety, and severe craving among others, as well as the cognitive effects, such as difficulty concentrating. This low smoking cessation success rate is also thought to be due to the long-lasting sensitization of nicotinic acetylcholine receptors (nAChRs) leading to long-term neuroadaptations in the brain’s reward system and alterations in synaptic plasticity that occur following chronic nicotine exposure and withdrawal.

Synthetic And Biological Exploration Of (+)-Boldine - Identification Of Potential Cns Receptor Ligands, Sujay Joseph
Synthetic And Biological Exploration Of (+)-Boldine - Identification Of Potential Cns Receptor Ligands, Sujay Joseph
Theses and Dissertations
(+)-Boldine, an aporphine alkaloid, is reported to be biologically active at various Central Nervous System(CNS) receptors. However, only a few Structure Activity Relationship(SAR) studies have been conducted using boldine’s aporphine scaffold. A library of novel analogs was synthesized from boldine to understand the effect of bisbenzylation at C2 and C9 positions on the affinity and selectivity at the serotonin receptors.
Relationship Between Cb1 And S1p Receptors In The Central Nervous System, Lauren Michele Collier
Relationship Between Cb1 And S1p Receptors In The Central Nervous System, Lauren Michele Collier
Theses and Dissertations
There is significant sequence homology and anatomical co-distribution between cannabinoid (CB1) and sphingosine-1-phosphate (S1P) receptors in the CNS, but potential functional relationships between these lysolipid receptors have not been examined. Therefore, to investigate possible relationships between these two systems at the level of G-protein activation, agonist-stimulated [35S]GTPγS binding and autoradiography were conducted. Autoradiographic studies were first performed to localize receptor-mediated G-protein activation in mouse brain. Coronal brain slices were processed for stimulation of [35S]GTPγS binding using the synthetic cannabinoid agonist WIN 55,212-2 (WIN) or SIP. High levels of WIN- and S1P-stimulated [35S]GTPγS binding were observed in the caudate putamen, hippocampus, …
