Genetic Risk Factors of Post-traumatic Stress Disorders in Solid Organ Transplant Recipients | Dr. Rebekah Nash | $39,886

Genetic Risk Factors of Post-traumatic Stress Disorders in Solid Organ Transplant Recipients Award: 39,886 Medical post-traumatic stress disorder (PTSD) can be triggered by any number of surgical or medical interventions or critical illness. For example, patients awaiting a solid organ transplant face the ever-present threat of death if a matching organ does not become available; following transplantation, they live with the ongoing risk of organ rejection. Currently, we are unable to accurately predict who will suffer from PTSD or other neuropsychiatric symptoms following transplantation. However, certain genetic variants have been associated with PTSD in the general population, and could serve as susceptibility factors for the transplant population. In this project, we are testing whether these variants can help us understand if, how, and why certain patients will develop PTSD and other neuropsychiatric symptoms following solid organ transplantation. Need/Problem: Relative [...]

Evaluating Oxytocin in Opioid Withdrawal: A Translational Study | Dr. Zoe McElligott | $50,000

Evaluating oxytocin in opioid withdrawal: a translational study Award: $50,000 As the opioid epidemic continues to spread in the United States, it’s important to discover new and more effective treatments. Using a preclinical model of opioid use disorder (OUD) in mice, we will investigate the ability of the hormone oxytocin to alleviate the physical opioid withdrawal symptoms, sleep dysregulation, and protracted affective behaviors. Need/Problem: e are currently experiencing a global opioid epidemic; however, the prevalence of opioid use disorder (OUD) is especially visible in the US, where drug overdose is now the leading cause of accidental death. Individuals who are dependent on opioids continue to take these drugs despite the negative consequences to their lives and the risk of death. A major factor driving this persistent drug taking is because opioid withdrawal is both a physically and mentally traumatic [...]

Depression in the Menopause Transition: Cortisol Circadian Rhythms and Sleep Impairment as Mechanisms of Risk | Dr. Paul Geiger | $38,400

Depression in the menopause transition: cortisol circadian rhythms and sleep impairment as mechanisms of risk Award: $38,400 The menopause transition (MT) is a vitally important, yet understudied, period of time in women’s health. Women in the MT experience significant hormonal changes (e.g., estrogen), are at a 2-4-fold increased risk for developing significant depressive symptoms, and report substantial changes in sleep health. In this project, we will examine the role of hormone variability on sleep impairment as a potential mechanism for the development of depression. Need/Problem: The menopause transition (MT) is a critical time period in women’s health, characterized by changes in reproductive hormones (changes in estrogen), a 2-4-fold increase risk for major depression (MDD), and the emergence of significant sleep impairment. To date, experimentally controlled sleep science research in women’s health is scant. Grant Summary: This research utilizes a [...]

A Mechanistic Examination of Continuous-Cycle Oral Contraceptive Administration in Bulimia Nervosa | Dr. Jessica Baker | $46,942

A Mechanistic Examination of Continuous-Cycle Oral Contraceptive Administration in Bulimia Nervosa Award: $46,942 Binge eating fluctuates in a predictable pattern over the course of the menstrual cycle, but how reproductive hormones influence these changes remains unknown. Reproductive hormones could influence binge eating through their impact on response to reward. In this project, we will stabilize reproductive hormone fluctuation in women with binge eating using oral contraceptives in order to address how this stabilization influences binge eating and reward responsivity. Understanding how reproductive hormones act on binge eating could lead to new and more effective treatments.   Dr. Jessica Baker, Ph.D. Need/Problem: There is a major disconnect between the negative consequences of eating disorders associated with binge eating and the availability of effective treatments. Female reproductive hormones such as estrogen and progesterone may play [...]

Dissecting the Neural Circuits of Hyperarousal States in Psychiatry | Dr. Jose Rodriguez-Romaguera | $200,000

Dissecting the Neural Circuits of Hyperarousal States in Psychiatry Award: 200,000 Anxiety is a complex state consisting of cognitive, emotional, and physiological components driven by a network across multiple brain regions. In this project, we plan on studying the neural circuits that regulate the hyperarousal state that often precedes the cognitive and emotional changes. Establishing the precise neural circuits involved in hyperarousal is critical to design novel therapeutic interventions for anxiety disorders. Need/Problem: Anxiety disorders are the most common mental illnesses in the United States, but we still poorly understand how specific neural circuits in the brain are affected during these disorders. Anxiety disorders are often characterized by an amplified arousal response to anxiogenic stimuli (hyperarousal). Grant Summary: Using pre-clinical mouse models we will use state-of-the-art microscopy techniques to visualize and record the activity of hundreds of individual neurons [...]

Quantifying the Brain Developmental Trajectory of Autism-Associated Brain Overgrowth Using 3D Cellular Resolution Imaging | Dr. Guorong Wu | $39,069

Quantifying the Brain Developmental Trajectory of Autism-Associated Brain Overgrowth Using 3D Cellular Resolution Imaging Award: $39,069 We aim to develop high throughput computational tools for 3D light-sheet microscopy images to quantify the brain developmental trajectory of autism-associated brain overgrowth. The computational tools developed in this project will be used to study cortical development in the mouse brain, including how typical development is altered by an autism-associated genetic mutation. Need/Problem: Alterations in brain development are associated with a variety of neuropsychiatric disorders, including autism spectrum disorder (ASD). Many studies demonstrate that mouse models re-capitulate a core human phenotype, brain overgrowth, associated with an increase in the neural progenitor pool and that this brain overgrowth shows a regionally specific pattern. However, we do not know the cell-types that are driving the effect. And due to the limited temporal resolution of previous [...]
