Despite its significant heritability, the genetic basis of Parkinson's disease (PD) remains incompletely understood. Here, in analyzing whole-genome sequence data from 3,809 PD cases and 247,101 controls in the UK Biobank, we discover that protein-truncating variants in ITSN1 confer a substantially increased risk of PD (p = 6.1 × 10

Metagenomic Signatures Of Extraintestinal Bacterial Infection In The Febrile Term Infant Gut Microbiome, Anna L Deveaux, Carla Hall-Moore, Nurmohammad Shaikh, Meghan Wallace, Carey-Ann D Burnham, David Schnadower, Nathan Kuppermann, Prashant Mahajan, Octavio Ramilo, Phillip I Tarr, Gautam Dantas, Drew J Schwartz

2020-Current year OA Pubs

BACKGROUND: Extraintestinal bacterial infections (EBIs), e.g., urinary tract infection, bacteremia, and meningitis, occur in approximately 10% of febrile infants younger than 60 days. Although many EBI-causing species commonly reside in the infant gut, proof that the digestive system is a pre-infection habitat remains unestablished.

RESULTS: We studied a cohort of febrile term infants <  60 days old who presented to one of thirteen US emergency departments in the Pediatric Emergency Care Applied Research Network from 2016 to 2019. Forty EBI cases and 74 febrile controls matched for age, sex, and race without documented EBIs were selected for analysis. Shotgun sequencing was performed of the gut microbiome and of strains cultured from the gut and extraintestinal site(s) of EBI cases, including blood, urine, and/or cerebrospinal fluid. Using a combination of EBI isolate genomics and fecal metagenomics, we detected an intestinal strain presumptively isogenic to the EBI pathogen (> 99.999% average nucleotide identity) in 63% of infants with EBIs. Although there was no difference in gut microbiome diversity between cases and controls, we observed significantly increased Escherichia coli relative abundance in the gut microbiome of infants with EBIs caused by E. coli. Infants with E. coli …

A Generalized Epilepsy Network Derived From Brain Abnormalities And Deep Brain Stimulation, Gong-Jun Ji, Nico U F Dosenbach, Et Al.

2020-Current year OA Pubs

Idiopathic generalized epilepsy (IGE) is a brain network disease, but the location of this network and its relevance for treatment remain unclear. We combine the locations of brain abnormalities in IGE (131 coordinates from 21 studies) with the human connectome to identify an IGE network. We validate this network by showing alignment with structural brain abnormalities previously identified in IGE and brain areas activated by generalized epileptiform discharges in simultaneous electroencephalogram-functional magnetic resonance imaging. The topography of the IGE network aligns with brain networks involved in motor control and loss of consciousness consistent with generalized seizure semiology. To investigate therapeutic …

Excessive androgen levels can severely affect female health. However, most existing models of androgen excess rely on exogenous androgen administration, which does not fully capture the effect of elevated local ovarian testosterone on reproductive and metabolic functions. Here, we report the development of a novel hyperandrogenic mouse model, Cyp17TM-625, generated by combining CRISPR-Cas9 and a Tet-On doxycycline system to induce Cyp17A1 overexpression in ovarian theca-interstitial cells. As a result, Cyp17TM-625 mice exhibited significantly elevated Cyp17A1 messenger RNA and protein levels, accompanied by increased testosterone concentrations without alterations in basal levels of estradiol, progesterone, luteinizing hormone, or follicle-stimulating hormone. These mice …

Microglial diversity arises from the interplay between inherent genetic programs and external environmental signals. However, the mechanisms by which these processes develop and interact within the growing brain are not yet fully understood. Here, we show that radial glia-expressed integrin beta 8 (ITGB8) activates microglia-expressed TGFβ1 to drive microglial development. Domain-restricted deletion of Itgb8 in these progenitors results in regionally restricted and developmentally arrested microglia that persist into adulthood. In the absence of autocrine TGFβ1 signaling, microglia adopt a similar phenotype, leading to neuromotor symptoms almost identical to Itgb8 mutant mice. In contrast, microglia lacking the canonical TGFβ signal transducers …

Delivering Guideline-Directed Medical Therapy For Heart Failure With Reduced Ejection Fraction As An Over-Encapsulated Polypill: Rationale And Protocol For The Combo-Hf-X Pilot Crossover Randomised Clinical Trial, Colette Dejong, Mark D Huffman, Anubha Agarwal, Et Al.

2020-Current year OA Pubs

INTRODUCTION: A four-drug regimen of guideline-directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) is underused, in part due to prescriber inertia and low patient adherence. Although fixed-dose combination pills ('polypills') have improved adherence and clinical outcomes for other conditions, there are no polypills available that combine multiple classes of GDMT for HFrEF. Pharmacy-level over-encapsulation, in which several tablets are combined into one capsule, offers an opportunity to create customised HFrEF polypills with the goal of improving delivery of HFrEF therapies.

METHODS AND ANALYSIS: In the COMBO-HF-X pilot crossover randomised clinical trial, we will enrol 30-40 patients …

Gene Expression Profiling Of Pancreatic Ductal Adenocarcinoma Cells In Hypercapnia Identifies Siah3 As A Novel Prognostic Biomarker, Nitzan Zohar, Ryan Maguire, Saed Khalilieh, Aditi Jain, Dmitriy Bosykh, Wilbur B. Bowne, Harish Lavu, Charles J. Yeo, Avinoam Nevler

Department of Surgery Faculty Papers

Hypercapnia is a key feature of the respiratory microenvironment in many pathologic conditions. It occurs both as a regional and as a systemic process, and it is associated with multiple metabolic changes such as mitochondrial dysfunction, decreased ATP production, and metabolic shift from glycolytic energy production to fatty acid metabolism. In the cancer tumor microenvironment, hypercapnia has been linked at times to enhanced cell migration, invasion, and chemoresistance. Our previous work has shown that hypercapnia-associated gene signatures can be used as prognostic biomarkers. However, unlike the hypoxia-inducible factor pathway, there are no validated targets to quantify hypercapnia. In this study, …

BACKGROUND: Previous work has shown a role of CCL2, a key chemokine governing monocyte trafficking, in atherosclerosis. However, it remains unknown whether targeting CCR2, the cognate receptor of CCL2, provides protection against human atherosclerotic cardiovascular disease.

METHODS: Computationally predicted damaging or loss-of-function (REVEL > 0.5) variants within CCR2 were detected in whole-exome-sequencing data from 454,775 UK Biobank participants and tested for association with cardiovascular endpoints in gene-burden tests. Given the key role of CCR2 in monocyte mobilization, variants associated with lower monocyte count were prioritized for experimental validation. The response to CCL2 of human cells transfected with these variants was tested …

Comorbid cardiovascular and metabolic risk factors (CVM) differentially impact brain structure and increase dementia risk, but their specific magnetic resonance imaging signatures (MRI) remain poorly characterized. To address this, we developed and validated machine learning models to quantify the distinct spatial patterns of atrophy and white matter hyperintensities related to hypertension, hyperlipidemia, smoking, obesity, and type-2 diabetes mellitus at the patient level. Using harmonized MRI data from 37,096 participants (45-85 years) in a large multinational dataset of 10 cohort studies, we generated five in silico severity markers that: i) outperformed conventional structural MRI markers with a ten-fold increase in effect …

Asymmetrical Glymphatic Dysfunction In Patients With Long Covid Associated Neurocognitive Impairment- Correlation With Bbb Disruption, Joga Chaganti, Tanush Talekar, Bruce J. Brew

Department of Radiology Faculty Papers

BACKGROUND AND PURPOSE: The glymphatic system, a waste clearance pathway, has been implicated in several neurological conditions associated with neuroinflammation. COVID-19 associated neurocognitive impairment, part of the post-acute sequelae of SARS-CoV-2 infection (PASC), is strongly associated with neuroinflammation and disrupted blood-brain barrier (BBB). Several studies have implicated a synergistic interaction between the glymphatic system dysfunction and BBB disruption. In this proof-of-concept study, we investigated the role of the MRI metric diffusion along the perivascular spaces DTI (DTI-ALPS) in patients with PASC and correlated this with the BBB capillary permeability metric- K trans derived from Dynamic contrast enhanced (DCE) perfusion.

Recurrent pregnancy loss, characterized by two or more failed clinical pregnancies, poses a significant challenge to reproductive health. In addition to embryo quality and endometrial function, proper oviduct function is also essential for successful pregnancy establishment. Therefore, structural abnormalities or inflammation resulting from infection in the oviduct may impede the transport of embryos to the endometrium, thereby increasing the risk of miscarriage. However, our understanding of the biological processes that preserve the oviductal cellular structure and functional integrity is limited. Here, we report that autophagy-related protein ATG14 plays a crucial role in maintaining the cellular integrity of the oviduct by …

Icos-Expressing Car-T Cells Mediate Durable Eradication Of Triple-Negative Breast Cancer And Metastasis, Shelley Herbrich, Mehdi Chaib, Padmanee Sharma

Faculty, Staff and Student Publications

Triple-negative breast cancer (TNBC) remains one of the most aggressive and therapeutically challenging breast cancer subtypes. In their recent study, Cao et al introduced a B7H3-specific chimeric antigen receptor (CAR)-T cell with constitutive inducible co-stimulator (ICOS) expression (ICOS-B7H3-CAR-T), which demonstrated eradication of TNBC, including metastases, in preclinical models. These CAR-T cells exploit the expression of ICOS ligand on TNBC cells, enhancing antitumor cytotoxicity through ICOS signaling. Compared with conventional B7H3-CAR-T cells, the ICOS-B7H3-CAR-T cells exhibited superior antitumor efficacy, increased cytokine secretion, and prolonged survival in xenograft murine models. This study highlights ICOS as a promising co-stimulatory molecule for improving CAR-T …
