Abstract:
The effects of activating dopaminergic D1 and D2 class receptors of the subthalamic projections that innervate the pars reticulata of the subtantia nigra (SNr) were explored in slices of the rat brain using the whole cell patch-clamp technique. Excitatory postsynaptic currents (EPSCs) that could be blocked by 6-cyano-7-nitroquinoxalene-2,3-dione and d-(−)-2-amino-5-phosphonopentanoic acid were evoked onto reticulata GABAergic projection neurons by local field stimulation inside the subthalamic nucleus in the presence of bicuculline.

Abstract:
Dopamine receptors are integral membrane proteins whose endogenous ligand is dopamine. They play a fundamental role in the central nervous system and dysfunction of dopaminergic neurotransmission is responsible for the generation of a variety of neuropsychiatric disorders. From an evolutionary standpoint, phylogenetic relationships among the DRD1 class of dopamine receptors are still a matter of debate as in the literature different tree topologies have been proposed. In contrast, phylogenetic relationships among the DRD2 group of receptors are well understood. Understanding the time of origin

AbstractUnderstanding common pharmacologic and clinical “class” actions associated with atypical antipsychotics certainly reveals how these agents are alike, but what about unique differences from one agent to another? Atypical antipsychotics are also a heterogeneous group of agents that have complex pharmacologic entities, acting upon multiple dopamine receptors (D2, D1 (D3, and D4) and multiple serotonin receptors (5-HT2A, 5-HT2C, 5-HT1A, and 5-HT1D, among others). Atypical antipsychotics also interact with noradrenergic (α1- and α2-adrenergic receptor blockade), histaminergic (H1-receptor b

Abstract:
Olanzapine is an atypical antipsychotic agent of the thienobenzodiazepine class. Olanzapine blocks multiple neurotransmitter receptors, including dopaminergic (D1, D2, D3, and D4), serotonergic (5-hydroxytryptamine 2A [5-HT2A], 5-HT2C, 5-HT3, and 5-HT6), adrenergic (α1), histaminic (H1), and muscarinic (M1, M2, M3, and M4) receptors. Olanzapine has a high affinity for the 5HT2A receptor, which is up to 5 times greater than the dopamine receptor, resulting in less propensity to the development of extrapyramidal side effects. The affinity of olanzapine for multiple receptors has lead to the iden

G protein—coupled receptors (GPCRs) represent a class of important therapeutic targets for drug discovery. The integration of GPCRs into contemporary high-throughput functional assays is critically dependent on the presence of appropriate G proteins. Given that different GPCRs can discriminate against distinct G proteins, a universal G protein adapter is extremely desirable. In this report, the authors evaluated two highly promiscuous Gα16/z chimeras, 16z25 and 16z44, for their ability to translate GPCR activation into Ca2+ mobilization using the fluorescence imaging plate reader (FLIPR) and a

AbstractDopamine D1 receptor (D1R) is an important drug target implicated in many psychiatric and neurological disorders. Selective agonism of D1R are sought to be the therapeutic strategy for these disorders. Most selective D1R agonists share a dopamine-like catechol moiety in their molecular structure, and their therapeutic potential is therefore limited by poor pharmacological properties in vivo. Recently, a class of non-catechol D1R selective agonists with a distinct scaffold and pharmacological properties were reported. Here, we report the crystal structure of D1R in complex with stimulat

The 30 trillion cells that self-assemble into a human being originate from the pluripotent stem cells in the inner cell mass of a human blastocyst. The discovery of induced pluripotent stem cells (iPSCs) makes it possible to approximate various aspects of this natural developmental process artificially by generating materials that can be used in invasive mechanistic studies of virtually all human conditions. In Parkinson’s disease, instructions computed by the basal ganglia to control voluntary motor functions break down, leading to widespread rhythmic bursting activities in the basal ganglia
