Journal ArticleDOI
Estrogen Receptor β Contributes to Both Hypertension and Hypothalamic Plasticity in a Mouse Model of Peri-Menopause.
Teresa A. Milner,Teresa A. Milner,Natalina H. Contoreggi,Fangmin Yu,Megan A. Johnson,Gang Wang,Clara Woods,Sanoara Mazid,Tracey A. Van Kempen,Elizabeth M. Waters,Bruce S. McEwen,Kenneth S. Korach,Michael J. Glass +12 more
TL;DR: In this paper, the role of estrogen receptor β (ERβ) signaling in the hypothalamic paraventricular nucleus (PVN) was investigated in a model of early stage ovarian failure (peri-AOF) characteristic of perimenopause.
Journal ArticleDOI
Chronic stress differentially alters mRNA expression of opioid peptides and receptors in the dorsal hippocampus of female and male rats.
Megan A. Johnson,Natalina H. Contoreggi,Joshua F. Kogan,Matthew Bryson,Batsheva R. Rubin,Jason D. Gray,Mary Jeanne Kreek,Bruce S. McEwen,Teresa A. Milner,Teresa A. Milner +9 more
TL;DR: In this paper, the expression of hippocampal opioid peptides and receptors in unstressed (US) and CIS estrus female and male adult (∼2.5 months old ) Sprague Dawley rats was determined using RNAScope in situ hybridization.
Journal ArticleDOI
Sex and chronic stress alter delta opioid receptor distribution within rat hippocampal CA1 pyramidal cells following behavioral challenges.
Batsheva R. Rubin,Megan A. Johnson,Jared M. Berman,Ellen Goldstein,Vera Pertsovskaya,Yan Zhou,Natalina H. Contoreggi,Andreina G. Dyer,Jason D. Gray,Elizabeth M. Waters,Bruce S. McEwen,Mary Jeanne Kreek,Teresa A. Milner,Teresa A. Milner +13 more
TL;DR: DORs within CA1 pyramidal cells remain positioned in naïve female rats to enhance sensitivity to DOR agonists and traffic to dendritic spines in naïve males where they can promote plasticity processes.
Journal ArticleDOI
Oxycodone injections not paired with conditioned place preference have little effect on the hippocampal opioid system in female and male rats.
Elina Ashirova,Natalina H. Contoreggi,Megan A. Johnson,Fatima Al-Khayat,Gabriela A. Calcano,Batsheva R. Rubin,Emma M. O’Cinneide,Yong Zhang,Yan Zhou,Lennox Gregoire,Bruce S. McEwen,Mary Jeanne Kreek,Teresa A. Milner +12 more
TL;DR: The results indicate that the majority of changes within hippocampal opioid circuits that would promote opioid‐associative learning processes in both females and males do not occur with Oxy administration alone, and instead must be paired with CPP.
Journal ArticleDOI
An automated platform for Assessing Working Memory and prefrontal circuit function
TL;DR: In this paper , the authors describe the development and validation of a platform that was designed specifically for automated, high-throughput assessments of working memory and simultaneous two-photon imaging in chronic stress studies.
