A Review Of Studies On Hiv Pre-Exposure Prophylaxis In Community Pharmacies In States With Restrictive Pharmacist Prescription Authority In The United States, Hongmei Wang, Dominique Guinn, Xavier Roshitha Ramisetty, Thomas P Giordano, Ivy O Poon

Faculty, Staff and Students Publications

Community pharmacies have unparalleled potential to increase access to pre-exposure prophylaxis medications (PrEP) for HIV prevention; however, only 17 out of 50 states in the United States have statewide authority for pharmacists to provide PrEP at community pharmacies. Few studies have reported on how pharmacists overcome the legislative barrier and provide PrEP services in restrictive pharmacy prescription states. The objective of this article is to identify the existing primary literature describing pharmacist PrEP services in the community in states with restrictive prescription authority. Methods: A systemic literature review was conducted to identify the primary literature that involved community pharmacy service …

Cd8Α Structural Domains Enhance Gucy2c Car-T Cell Efficacy, Trevor R. Baybutt, Ariana A. Entezari, Adi Caspi, Ross E. Staudt, Robert D. Carlson, Scott A. Waldman, Adam E. Snook

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Despite success in treating some hematological malignancies, CAR-T cells have not yet produced similar outcomes in solid tumors due, in part, to the tumor microenvironment, poor persistence, and a paucity of suitable target antigens. Importantly, the impact of the CAR components on these challenges remains focused on the intracellular signaling and antigen-binding domains. In contrast, the flexible hinge and transmembrane domains have been commoditized and are the least studied components of the CAR. Here, we compared the hinge and transmembrane domains derived from either the CD8ɑ or CD28 molecule in identical GUCY2C-targeted third-generation designs for colorectal cancer. While these structural …

Understanding the mechanisms underlying immune evasion is crucial for developing novel anticancer modalities. To systematically uncover tumor-intrinsic genetic modulators involved in immune escape in tumor microenvironment, we performed genome-scale in vivo CRISPR screens in two syngeneic models and later expanded up to seven syngeneic models with a focused validation library. These data help us better understand tumor immune evasion and pave the way for developing effective therapeutics. Importantly, we uncovered that Mga depletion elicited an antitumor immune response and inhibited tumor growth in triple-negative breast cancer. Our findings suggest that Mga may play a role in modulating the tumor immune …

Predictors Of Transition From Child And Adolescent Bipolar Not Otherwise Specified To Bipolar I Disorder, A Longitudinal 3.9-Year Study., María Ribeiro-Fernández, Azucena Díez-Suárez, Kiki D Chang, Cesar A Soutullo

Stimulation Of An Entorhinal-Hippocampal Extinction Circuit Facilitates Fear Extinction In A Post-Traumatic Stress Disorder Model, Ze-Jie Lin, Xue Gu, Wan-Kun Gong, Mo Wang, Yan-Jiao Wu, Qi Wang, Xin-Rong Wu, Xin-Yu Zhao, Michael X Zhu, Lu-Yang Wang, Quanying Liu, Ti-Fei Yuan, Wei-Guang Li, Tian-Le Xu

Faculty, Staff and Student Publications

Effective psychotherapy of post-traumatic stress disorder (PTSD) remains challenging owing to the fragile nature of fear extinction, for which the ventral hippocampal CA1 (vCA1) region is considered as a central hub. However, neither the core pathway nor the cellular mechanisms involved in implementing extinction are known. Here, we unveil a direct pathway, where layer 2a fan cells in the lateral entorhinal cortex (LEC) target parvalbumin-expressing interneurons (PV-INs) in the vCA1 region to propel low-gamma-band synchronization of the LEC-vCA1 activity during extinction learning. Bidirectional manipulations of either hippocampal PV-INs or LEC fan cells sufficed for fear extinction. Gamma entrainment of vCA1 …

Although hemodynamic stress plays a key role in aneurysm formation outside of sickle cell disease (SCD), its role is understudied in patients with SCD. We hypothesized that tissue-based markers of hemodynamic stress are associated with aneurysm presence in a prospective SCD cohort. Children and adults with SCD, with and without aneurysms, underwent longitudinal brain magnetic resonance imaging/magnetic resonance angiography (MRA) to assess cerebral blood flow (CBF) and oxygen extraction fraction (OEF). Baseline characteristics were recorded. In the subgroup of adults, stepwise mixed-effect logistic regression examined clinical variables, CBF, and OEF as predictors of aneurysm presence. Cumulative rates of new aneurysm …

Faculty, Staff and Students Publications

Many Parkinson’s disease (PD) models overexpress α-Synuclein using heterologous promoters, which is adequate to demonstrate that excessive α-Synuclein is toxic but not ideal for learning the precise ontogeny of the disease pathogenesis, specifically where the disease starts and how it progresses. To answer these questions, it is beneficial to generate a mouse model expressing a disease-causing mutation under the endogenous promoter. Here, we generated three Snca knock-in mice. Among them, homozygous Snca^G51D mice develop motor deficits by 9 mo of age. These mice exhibit olfactory and gastrointestinal abnormalities by 6 mo. They lose dopaminergic neurons and have reduced dopamine …

Neuroprotective Effects Of Magnesium: Implications For Neuroinflammation And Cognitive Decline, Veer Patel, Nuraly S. Akimbekov, William B. Grant, Carolyn Dean, Xiaoqian Fang, Mohammed S. Razzaque

School of Medicine Publications

Neurodegenerative diseases, which are characterized by progressive neuronal loss and cognitive decline, are a significant concern for the aging population. Neuroinflammation, a shared characteristic of these diseases, is implicated in their pathogenesis. This article briefly summarizes the role of magnesium, an essential mineral involved in numerous enzymatic reactions and critical for neuronal bioactivity, in the context of neuroinflammation and cognitive decline. The potential neuroprotective effects of magnesium, including the mechanisms of neuroprotection by magnesium through maintaining neuronal ion homeostasis, reducing inflammation, and preventing excitotoxicity, are also described. Additionally, we discuss the impact of inadequate magnesium on neuroinflammation and its potential …

Codesigning A Clinical Prediction Model For Aboriginal Perinatal Mental Health Using Glassbox Ai And Aboriginal Wisdom And Lived Experience, Guanjin Wang, Hachem Bennamoun, Wai Hang Kwok, Rhonda Marriott, Roz Walker, Jayne Kotz

Research outputs 2022 to 2026

Perinatal mental health is vital for mothers, infants, and families. Aboriginal mothers, despite their strengths, face greater mental health disparities due to colonisation and trauma. Traditional screening methods lack cultural sensitivity. The Baby Coming You Ready (BCYR) program offers a culturally sensitive assessment with promising pilot results. To support health professionals, an AI solution using the Explainable Boosting Machine (EBM) is proposed, trained with Aboriginal lived experiences. This model identifies maternal protective and risk factors, offering interpretable predictions for holistic culturally sensitive care.

Neurovascular coupling (NVC) and neurometabolic coupling (NMC) provide the basis for functional magnetic resonance imaging and positron emission tomography to map brain neurophysiology. While increases in neuronal activity are often accompanied by increases in blood oxygen delivery and oxidative metabolism, these observations are not the rule. This decoupling is important when interpreting brain network organization (e.g., resting-state functional connectivity [RSFC]) because it is unclear whether changes in NMC/NVC affect RSFC measures. We leverage wide-field optical imaging in Thy1-jRGECO1a mice to map cortical calcium activity in pyramidal neurons, flavoprotein autofluorescence (representing oxidative metabolism), and hemodynamic activity during wake and ketamine/xylazine anesthesia. …

Loss-of-function mutations in the C terminus of TPL2 kinase promote oncogenesis by impeding its proteasomal degradation, leading to sustained protein expression. However, the degradation mechanism for TPL2 has remained elusive. Through proximity-dependent biotin identification (BioID), we uncovered tripartite motif-containing 4 (TRIM4) as the E3 ligase that binds and degrades TPL2 by polyubiquitination of lysines 415 and 439. The naturally occurring TPL2 mutants R442H and E188K exhibit impaired TRIM4 binding, enhancing their stability. We further discovered that TRIM4 itself is stabilized by another E3 ligase, TRIM21, which in turn is regulated by KRAS. Mutant KRAS recruits RNF185 to degrade TRIM21 and …

While there was no group difference in perceived anxiety levels, participants …

Harnessing The Power Of Integrated Behavioral Health To Enhance Insomnia Intervention In Primary Care, Rebecca L. Campbell, Ana Bridges

Psychological Science Faculty Publications and Presentations

Insomnia is prevalent in primary care and associated with co-morbid physical and mental health conditions and poor health outcomes. While there are effective treatments for insomnia in specialty mental health care, many patients have difficulty accessing these interventions. To begin, patients do not always report their sleep challenges to physicians; meanwhile, primary care providers often do not screen for insomnia symptoms. Furthermore, patients may experience several barriers to accessing specialty care for insomnia treatment, such as a limited number of available providers, financial burden, lack of transportation, and low perceptions of treatment effectiveness. Primary care behavioral health (PCBH) is well-equipped …
