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.

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 …

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 …

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 …

Multiple myeloma (MM) is an incurable malignancy of plasma cells, with over 35,000 new cases diagnosed annually in the United States. Despite an expanding arsenal of approved therapies, nearly all patients relapse, and mechanisms underlying disease progression remain poorly understood. In particular, the role of long non-coding RNAs (lncRNAs) in MM progression and treatment response is largely unexplored. To address this gap, we performed transcriptome sequencing of newly diagnosed MM (NDMM) patient samples and compared individuals with short progression-free survival (PFS; < 24 months) to those with prolonged PFS (>24 months) following standard first-line therapy. We identified 157 lncRNAs upregulated in patients with short PFS, and prioritized the …

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 …

ATP5F1A encodes the α-subunit of complex V of the respiratory chain, which is responsible for mitochondrial ATP synthesis. We describe 6 probands with heterozygous de novo missense ATP5F1A variants that presented with developmental delay, intellectual disability, and movement disorders. All variants were located at the contact points between the α- and β-subunits. Functional studies in C. elegans revealed that the variants were damaging via a dominant negative genetic mechanism. Biochemical and proteomics studies of proband-derived cells showed a marked reduction in complex V abundance and activity. Mitochondrial physiology studies revealed increased oxygen consumption, yet decreased mitochondrial membrane potential and ATP …

A biochemical deficiency of mitochondrial complex I (CI) underlies approximately 30% of cases of primary mitochondrial disease, yet the inventory of molecular machinery required for CI assembly remains incomplete. We previously characterised patients with isolated CI deficiency caused by segregating variants in RTN4IP1, a gene that encodes a mitochondrial NAD(P)H oxidoreductase. Here, we demonstrate that RTN4IP1 deficiency causes a CI assembly defect in both patient fibroblasts and knockout cells, and report that RTN4IP1 is a bona fide CI assembly factor. Complexome profiling revealed accumulation of unincorporated ND5-module and impaired N-module production. RTN4IP1 patient fibroblasts also exhibited defective coenzyme Q biosynthesis, …
