Sickle cell disease (SCD), an inherited blood disorder caused by a mutation in the β-globin gene, is characterized by sickle erythrocytes that are prone to hemolysis, leading to anemia and vaso-occlusion crises. In sickle erythrocytes, hemoglobin aggregation is followed by altered cation permeability and subsequent dehydration. Interventions that restore cation permeability can decrease hemolysis and ameliorate the symptoms associated with SCD. PIEZO1 is a nonselective mechanosensitive cation channel that regulates erythrocyte volume. Gain-of-function (GOF) mutations in PIEZO1 cause hemolytic anemia by increasing cation permeability, leading to erythrocyte dehydration in humans and mice. Although PIEZO1 plays a key role in erythrocyte …

Performance Evaluation Of A Commercial Multiplex Pathogen Panel For Detection Of Bacteria In Sputum Specimens From Non-Icu Patients With Suspected Lower Respiratory Tract Infection, Madeline Gemoules, Tristan T Timbrook, Elizabeth Neuner, Rebekah E Dumm, Tamara Krekel

2020-Current year OA Pubs

Rapid diagnostic testing can improve pathogen detection and lead to targeted antibiotics. The BioFire FilmArray Pneumonia Panel (BFPP) is a multiplex PCR that has displayed strong concordance with traditional microbiologic techniques. However, most existing literature focuses on deep respiratory specimens, and there is sparse literature on performance in sputum specimens. This retrospective, single-center study included adult patients between 1 September 2022 and 31 August 2024 who had collection of a BFPP with standard of care (SOC) culture from a sputum specimen on a non-intensive care unit (ICU) floor or in the emergency department if admitted to a non-ICU floor.

Traumatic brain injury (TBI) is an environmental risk factor for dementia and long-term neurological deficits, posing a significant public health challenge. TBI-induced neuroinflammation involves both brain-resident microglia and peripheral monocyte-derived macrophages (MDMs). Previous research has shown that MDMs contribute to the development of long-term memory deficits, yet their long-term behavior following brain infiltration remains unclear. To address this, our study uses two complementary fate-mapping mouse lines, CCR2-creERT2 and Ms4a3-cre, for precise and lasting tracking of MDMs in vivo. Here we show that MDMs persist in the brain for at least 8 months post-TBI in both male and female mice. MDMs …

The circadian clock controls 24-h rhythmic processes. However, how genetic variations outside clock genes impact peripheral diurnal rhythms remains largely unknown. Here, we find that genetic variation contributes to different diurnal patterns of hepatic gene expression in both humans and mice. Nutritional challenges alter the rhythmicity of gene expression in mouse liver in a strain-specific manner. Remarkably, genetics and nutrition interdependently control more than 80% of rhythmic gene and enhancer-promoter interactions (E-PIs), with a noncanonical clock regulator, estrogen-related receptor gamma (ESRRγ), emerging as a top transcription factor during motif mining. Knockout of Esrrγ abolishes strain-specific metabolic processes in response to …

All-Optical Voltage Interrogation For Probing Synaptic Plasticity In Vivo, Jacques Carolan, Michelle A Land, Xiaoyu Lu, Maxime Beau, Dimitar Kostadinov, François St-Pierre, Beverley A Clark, Michael Häusser

Faculty, Staff and Students Publications

Measuring synaptic efficacy and defining the rules for induction of synaptic plasticity at identified connections in the mammalian brain is essential for understanding how synapses contribute to learning and memory. This requires new approaches to selectively evoke presynaptic activity and measure postsynaptic responses with high spatiotemporal resolution and high sensitivity over long periods in vivo. Here we develop an all-optical approach to probe synaptic plasticity at identified cerebellar synapses in awake, behaving mice. We developed and applied JEDI-2Psub, a genetically encoded voltage indicator with increased sensitivity around resting membrane potentials, to record subthreshold and suprathreshold activity in Purkinje cell (PC) …

The immune environment surrounding the brain plays a fundamental role in monitoring signs of injury. Insults, including ischemic stroke, can disrupt this balance and incite an exaggerated inflammatory response, yet the underlying mechanism remains unclear. Here, we show that the mast-cell-specific receptor Mrgprb2 regulates post-stroke brain inflammation from the meninges. Mrgprb2 causes meningeal mast cell degranulation after stroke, releasing immune mediators. This process recruits skull bone marrow neutrophils into the dura and further promotes neutrophil migration from the dura into the brain by cleaving the chemorepellent semaphorin 3a. We demonstrate that the human ortholog, MRGPRX2, is expressed in human meningeal …

Van der Woude syndrome (VWS) is an autosomal dominant disorder characterized by lower lip pits and orofacial clefts (OFCs). With a prevalence of ∼1 in 35,000 live births, it is the most common form of syndromic clefting. Most VWS is attributed to variants in IRF6 (∼70%) or GRHL3 (∼5%), leaving up to 25% of individuals without a molecular diagnosis. Both IRF6 and GRHL3 function in a transcriptional regulatory network (TRN) governing differentiation of periderm, a single epithelial cell layer preventing pathological adhesions during palatogenesis. Periderm disruption can elicit a spectrum of phenotypes, including lip pits and OFCs, pterygia, and severe …

What Community Members With Chronic Illness Teach Future Healthcare Professionals In A Longitudinal Interprofessional Education Program: A Focus Group Study, Rachel White, Maria Brucato, Amber King, Anne B. Mitchell, Nethra S. Ankam

Department of Medicine Faculty Papers

INTRODUCTION: Nearly 50% of Americans have at least one chronic illness. Preparing future healthcare providers for interprofessional collaborative practice (IPCP) and person-centred care through community-based interprofessional education (IPE) can improve outcomes for this growing population. Partial programme theories predict that patients' participation as teachers in health professions education contributes to students' development of patient-centredness. Role theory asserts that behaviours are shaped by assigned roles; therefore, community members with chronic illness who assume roles of health mentors in an IPE curriculum are predicted to teach students about their patient experiences. Yet, this teaching outcome and the lessons health mentors teach in …

The Brown Foundation: Institute of Molecular Medicine

The role of chromatin biology and epigenetics in disease progression is gaining increasing recognition. Genes that escape X chromosome inactivation (XCI) can impact neuroinflammation through epigenetic mechanisms. Our previous study has suggested that the X escapee genes Kdm6a and Kdm5c are involved in microglial activation after stroke in aged mice. However, the underlying mechanisms remain unclear. We hypothesized that Kdm6a/5c demethylate H3K27Me3/H3K4Me3 in microglia, respectively, and mediate the transcription of interferon regulatory factor 5 (IRF5) and IRF4, leading to microglial pro-inflammatory responses and exacerbated stroke injury. Aged (17–20 months) Kdm6a/5c microglial conditional knockout (CKO) female mice (one allele of the …

Tumor associated macrophages (TAMs) directly contribute to the dismal prognosis of glioblastoma by preventing anti-tumor immunity and promoting tumor invasion and angiogenesis. Inhibiting TAM infiltration is a potential therapeutic strategy in glioblastoma, with several chemokine antagonists in early clinical development. Hydrogen sulfide, a gasotransmitter that regulates microglial accumulation in a wide range of CNS diseases, may be a novel therapeutic target to prevent TAM recruitment in glioblastoma. In this study, hydrogen sulfide concentrations were directly measured from 14 isocitrate dehydrogenase (IDH)-wildtype glioblastoma surgical samples and compared against overall survival as well as expression of TAM markers and chemokines. Effects of …
