Cocaine-Induced Reinstatement Of A Conditioned Place Preference In Developing Rats: Involvement Of The D2 Receptor, Kimberly A. Badanich, Cheryl L. Kirstein
Cocaine-Induced Reinstatement Of A Conditioned Place Preference In Developing Rats: Involvement Of The D2 Receptor, Kimberly A. Badanich, Cheryl L. Kirstein

Reinstatement of conditioned place preferences have been used to investigate physiological mechanisms mediating drug-seeking behavior in adolescent and adult rodents; however, it is still unclear how psychostimulant exposure during adolescence affects neuron communication and whether these changes would elicit enhanced drug-seeking behavior later in adulthood. The present study determined whether the effects of intra-ventral tegmental area (VTA) or intra-nucleus accumbens septi (NAcc) dopamine (DA) D2 receptor antagonist infusions would block (or potentiate) cocaine-induced reinstatement of conditioned place preferences. Adolescent rats (postnatal day (PND 28–39)) were trained to express a cocaine place preference. The involvement of D2 receptors on cocaine-induced reinstatement …

One of the largest obstacles in drug development is to overcome solubility and bioavailability problems. Preformulation strategies such as nanoparticle formation are often employed but sometimes create new issues and are limited in their effectiveness and applications. Since the majority of drugs are marketed and sold as solid forms, drug delivery systems are not always desirable. This is where solid-state chemistry becomes important. Traditional solid-state chemistry approaches are often successful but are sometimes too restrictive and cannot be applied to certain compounds. Cocrystals have emerged as an alternative solid-state technique that can be applied to a broad range of compounds. …
Maternal Immune Dysregulation In The Pathogenesis Of Neurodevelopmental Disorders: Interleukin-6 As A Central Mechanism And Therapeutic Target Of Flavonoids, Ellisa Carla Parker-Athill
Maternal Immune Dysregulation In The Pathogenesis Of Neurodevelopmental Disorders: Interleukin-6 As A Central Mechanism And Therapeutic Target Of Flavonoids, Ellisa Carla Parker-Athill

Activation of the maternal immune system and resultant maternal cytokine expression due to prenatal infection has been implicated as a significant contributor to the pathology of neuropsychiatric and neurodevelopmental disorders such as schizophrenia and Autism Spectrum Disorder (ASD). Increased maternal interleukin-6 (IL-6) expression, observed clinically and in animal models of prenatal infection, and resultant activation of key signaling pathways, has been shown to be a biological indicator of pathology, and a central component of the pathological mechanism. In animal models of prenatal infection and clinically in pregnancy disorders hallmarked by immunological irregularities and increased IL-6 expression, inhibition of IL-6 has …

In our previous work we demonstrated that the integrin antagonist, HYD1, induced necrotic cell death in myeloma cell lines in vitro and in vivo as a single agent. In order to further delineate biomarkers of response to HYD1 we developed an isogenic drug resistant variant named H929-60. We show that the acquisition of resistance towards HYD1 correlates with reduced expression of the cleaved α4 integrin subunit and beta 1 integrin. Moreover, we demonstrate that HYD1 interacts with α4 integrin in myeloma cells. Consistent with reduced VLA-4 expression, the resistant variant showed ablated functional binding to fibronectin, VCAM-1 and the bone …
Use And Development Of Computational Tools In Drug Discovery: From Small Molecules To Cyclic Peptides, Daniel Navarrete Santiago
Use And Development Of Computational Tools In Drug Discovery: From Small Molecules To Cyclic Peptides, Daniel Navarrete Santiago

The scope of this work focuses on computationally modeling compounds with protein structures. While the impetus of drug discovery is the innovation of new therapeutic molecules, it also involves distinguishing molecules that would not be an effective drug. This can be achieved by inventing new tools or by refining old tools. Virtual screening (VS, also called docking), the computational modeling of a molecule in a receptor structure, is a staple in predicting a molecule's affinity for an intended target. In our Virtual Target Screening system (also called inverse-docking), VS is used to find high-affinity targets, which can potentially explain absorption, …
