Cortisol Receptor Sensitivity As A Risk Factor For Depression, Michela Michielli
Cortisol Receptor Sensitivity As A Risk Factor For Depression, Michela Michielli
Honors Theses
In 2020, the World Health Organization reported over 264 million people across the world were suffering from depression. Studies have demonstrated that one source of depression is a hormonal imbalance involved in the stress response. Cortisol is a stress hormone regulated by the Hypothalamic-Anterior-Pituitary (HPA) Axis. Its effects on the stress response and other metabolic activities in the body are exerted through the glucocorticoid and mineralocorticoid receptors (GR and MR respectively).
Our research has examined mutations known as single-nucleotide-polymorphisms (SNPs) relating to cortisol-receptor sensitivity and the behavior of cortisol in the body to investigate the link between cortisol activity and …
Hiv-1 Tat Interactions With Opioids Are Modulated By Progesterone And Estradiol, Dejun Jackson
Hiv-1 Tat Interactions With Opioids Are Modulated By Progesterone And Estradiol, Dejun Jackson
Honors Theses
HIV infection and combined substance abuse are comorbid epidemics. Previous studies show that concurrent opioid drug use may potentiate HIV-1-mediated neurotoxicity partly via interactions with opioids. Preclinical studies suggest that the HIV-1 trans-activator of transcription (Tat), an HIV regulatory protein, can synergize with opioids to exacerbate its already neurotoxic effects. However, its interactions with clinical opioids, such as oxycodone, have yet to be elucidated. Additionally, Tat disrupts a number of systems including the dopaminergic system, which contribute to its capacity to potentiate the rewarding effects of abused drugs. Although the neurotoxic effects of Tat may be inhibited by gonadal steroids …
