Talc pleurodesis is highly effective for preventing recurrence of pneumothorax and pleural effusion, but it can be complicated by dissemination, acute lung injury, lead exposure, and foreign body-induced chronic inflammation and pain. Our objective is to develop a safe, biodegradable, contaminant-free particle for pleurodesis. We used mouse models of pneumothorax and malignant pleural effusion to compare the efficacy and safety of pleurodesis with talc and hydroxyapatite microspheres (HAM). Intrapleural instillation of microspheres induced pleural adhesions, fibrosis, and symphysis as effectively as talc and resulted in more durable protection from experimental pneumothorax. HAM and talc both induced an osteoclastogenic, inflammatory, and …

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 …

Fiber Recruitment Drives A Phase Transition Of Cell Polarization At A Critical Cell Spacing In Matrix-Mediated Tissue Remodeling, Xiangjun Peng, Yuxuan Huang, Wenyu Kong, Yanan Du, Elliot L Elson, Xi-Qiao Feng, Guy M Genin

2020-Current year OA Pubs

Biological tissues exhibit sharp phase transitions where cells collectively transition from disordered to ordered states at critical densities. We demonstrate through bio-chemo-mechanical modeling that this emergent behavior arises from a nonmonotonic dependence on nonlinear extracellular matrix (ECM) mechanics: mechanical communication between cells is optimized at intermediate stiffness values where cells can both generate sufficient forces and create strain-stiffened tension bands in the ECM. This balance establishes a critical cell spacing threshold for cell-cell communication ([Formula: see text]100 to 200 [Formula: see text]m) that is conserved across experimental observations for a broad range of cell types and collagen densities. Our model …

Apoe-Calypse Tau: Apoe-Tau Synergy In Alzheimer's Disease, Matthew Paul Lennol, Chiara Bordier, Léana Kamelher, Jason D Ulrich, David M Holtzman, Maud Gratuze

2020-Current year OA Pubs

Alzheimer's disease (AD), the most common cause of dementia, is characterized by the accumulation of amyloid-β (Aβ) in senile plaques and abnormally hyperphosphorylated tau proteins in neurofibrillary tangles. While much of the research has focused on Aβ, tau-mediated neurodegeneration is more closely associated with synaptic loss and cognitive decline in AD, emphasizing the need for a deeper understanding of tau pathology. In this context, the interaction between tau and APOE, particularly the main genetic risk factor for AD APOE ε4, remains underexplored. APOE encodes apolipoprotein E (apoE), a protein important in lipid metabolism. In addition to promoting Aβ deposition, emerging …

Chimeric Antigen Receptor Natural Killer (Car-Nk) Cells: From Preclinical Promise To Clinical Reality In Cancer Immunotherapy, Hunter Cassidy Cochran, Kevin Ashkan Ghobadi, Armin Ghobadi

2020-Current year OA Pubs

Chimeric antigen receptor (CAR) natural killer (NK) cell therapy represents an emerging frontier in cancer immunotherapy. CAR-NK cells offer the potential for "off-the-shelf" treatments with a favorable safety profile, due in part to their innate capacity for HLA-unrestricted tumor targeting and an absence of graft-versus-host disease. Landmark clinical studies using cord blood - derived CAR-NK cells and another employing iPSC-derived CAR-NK cells have reported impressive response rates, durable remissions, and minimal toxicity. Furthermore, a growing landscape of ongoing clinical trials is exploring innovative strategies to enhance persistence, overcome solid tumor challenges, and prevent antigen escape. These advances collectively underscore the …

Recent Advances In The Identification And Quantification Of Xylazine And Medetomidine In Biological Specimens, Bridgit O Crews

2020-Current year OA Pubs

Xylazine is a veterinary sedative that is frequently detected in the illicit drug supply, often found mixed with illicitly manufactured fentanyl (IMF). It has been detected in the blood of overdose victims and patients who use illicit drugs. Xylazine is not approved for use in humans. It is an alpha-2-adrenergic receptor agonist that causes deep sedation that is non-responsive to naloxone, the antidote for opioid overdose. Chronic exposure to xylazine has been linked to severe wounds that can progress to amputation. Medetomidine is another related veterinary sedative that has more recently emerged as an adulterant in IMF. Medetomidine is also …

Cognitive abilities are heritable and influenced by socioeconomic status (SES). It is critical to understand the association between SES and cognition beyond genetic propensity to inform potential benefits of SES-based interventions and to determine if such associations vary across (i) cognitive domains, (ii) facets of SES, and/or (iii) genetic propensity for different aspects of cognition. We examined the contributions of neighborhood socioeconomic advantage, family income, and polygenic scores (PGS) for domains of cognition (i.e., general cognitive ability, executive function, learning and memory, fluid reasoning) in a sample of children (ages 9-10;

A Modification To The Brand Transfer For Claw Hand: The Four-Tailed Extensor Carpi Radialis Brevis To Lateral Band Transfer, Lauren E Wessel, Nirbhay S Jain, Ambika E Paulson, Carrie Bettlach, Mitchell A Pet, Amy M Moore

2020-Current year OA Pubs

BACKGROUND: Claw deformity is a devastating consequence of low ulnar nerve palsy, resulting in loss of finger function. Traditionally, the Brand transfer is a favored intervention but requires lengthy grafts and bulky tenorrhaphies, risking adhesions in the lumbrical canal. We present a modified Brand tendon transfer, which extends the extensor carpi radialis brevis (ECRB) into 4 tails for individual grafting into the lateral band, decreasing adhesion risk and graft length need.

METHODS: Nine consecutive patients with claw hand were examined in detail to confirm the diagnosis and appropriateness for claw-correction surgery by the senior author. All patients underwent our modified …

Myocardial infarction (MI) continues to be a leading cause of death worldwide. Even though it is well established that the complex interplay between different cell types determines the overall healing response after MI, the precise changes in the tissue architecture are still poorly understood. In this study, we generated an integrative cellular map of the acute phase after murine MI using a combination of imaging-based transcriptomics (Molecular Cartography) and antibody-based highly multiplexed imaging (Sequential Immunofluorescence). This enabled us to evaluate cell type compositions and changes at subcellular resolution over time. We observed the recruitment of leukocytes to the infarcted heart …

Development Of A Leucine-Rich Repeat-Containing Protein 15-Targeted Radio-Immunotheranostic Approach To Deplete Pro-Tumorigenic Mechanisms And Immunotherapy Resistance, Claire M Storey, Abbie Hasson, Diane Abou, Daniel Thorek, Et Al.

2020-Current year OA Pubs

Leucine-rich repeat containing 15 (LRRC15) has emerged as an attractive biomarker and target for cancer therapy. Transforming growth factor-β (TGFβ) induces the expression of this plasma membrane protein specifically in aggressive and treatment resistant tumor cells derived from mesenchymal stem cells, with minimal expression observed in non-neoplastic tissues. We have developed a humanized monoclonal antibody, DUNP19, that specifically binds with high affinity to a phylogenetically conserved LRRC15 epitope and is rapidly internalized upon LRRC15 binding. In multiple subcutaneous and orthotopic tumor xenograft mouse models, Lutetium-177 labeled DUNP19 ([

Neurofibromatosis type 1 (NF1) is among the most common neurogenetic disorders and is associated with an increased risk of developing tumors in the nervous system. Additionally, up to 80% of patients with NF1 experience neurological complications, including deficits in attention, memory, and executive function. Significant effort has been dedicated to studying how NF1 mutations autonomously dysregulate neuronal function. Increasing evidence indicates that NF1 mutations also dysregulate the oligodendroglial lineage that contributes to neurological issues in NF1. Here, we summarize our current understanding of how NF1 mutations impact the oligodendroglial lineage homeostasis and plasticity. We also discuss gaps in knowledge, potential …

The lysosome integrates anabolic signaling and nutrient sensing to regulate intracellular growth pathways. The leucine-rich repeat-containing 8 (LRRC8) channel complex forms a lysosomal anion channel and regulates PI3K-AKT-mTOR signaling, skeletal muscle differentiation, growth, and systemic glucose metabolism. Here, we define the endogenous LRRC8 subunits localized to a subset of lysosomes in differentiated myotubes. We show that LRRC8A affects leucine-stimulated mTOR; lysosome size; number; pH; expression of lysosomal proteins LAMP2, P62, and LC3B; and lysosomal function. Mutating an LRRC8A lysosomal targeting dileucine motif sequence (LRRC8A-L706A;L707A) in myotubes recapitulates the abnormal AKT signaling and altered lysosomal morphology and pH observed in LRRC8A …

Antibiotic resistance is a threat to human health, yet recent work highlights how loss of resistance may drive pathogenesis in some bacteria. In two recent studies, we found that β-lactam antibiotics and nutrient stresses faced during infection selected for genetic inactivation of the Pseudomonas aeruginosa antibiotic efflux pump mexEFoprN. Unexpectedly, efflux pump mutations increased P. aeruginosa virulence during infection; however, neither the prevalence of mexEFoprN inactivating mutations in real human infections, nor the mechanisms driving increased virulence of efflux pump mutants are known. We hypothesized that human infection would select for virulence enhancing mutations. Using genome sequencing of clinical isolates, …

Site-1 Protease Is A Negative Regulator Of Sarcolipin Promoter Activity, Isha Sharma, Meredith O Kelly, Katelyn Hanners, Ella S Shin, Muhammad G Mousa, Shelby Ek, Gretchen A Meyer, Rita T Brookheart

2020-Current year OA Pubs

The timed contraction and relaxation of myofibers in tissues such as the heart and skeletal muscle occur via the tightly regulated movement of calcium ions into and out of the sarcoplasmic reticulum (SR). In skeletal muscle, this phenomenon enables humans to exercise, perform day-to-day tasks, and to breathe. Sarcolipin, a small regulatory protein, prevents calcium ions from entering the SR by binding to and inhibiting SERCA, contributing to myofiber contraction. Disruptions in sarcolipin (SLN) expression are implicated in the pathophysiology of obesity and musculoskeletal disease. However, the mechanisms regulating sarcolipin expression are not clearly understood. We recently showed that site-1 …
