Identification Of Distinct Subtypes In Immune Tolerance After Hematopoietic Cell Transplantation Using The Prospective Able1.0 Pediatric Study Cohort, Bernard Ng, Shalini Shenoy, Et Al.
2020-Current year OA Pubs
The lack of immune tolerance after hematopoietic cell transplantation (HCT) can result in chronic graft-versus-host disease (cGvHD), which is the primary nonrelapse limitation of successful HCT. To date, immune tolerance has been considered a single biological entity, but we hypothesized that post-HCT immune tolerance could develop through multiple pathways. Using the ABLE network database, which comprises measurements of 75 cell populations, 10 cytokines and chemokines, lymphocyte population telomere length, KRECs and TRECs, and 132 metabolites from the largest pediatric cGvHD cohort (n = 241), we applied clustering analysis to patients with primary immune tolerance (PIT; no acute GvHD [aGvHD] or …

2020-Current year OA Pubs
BACKGROUND & AIMS: Patients with advanced hepatocellular carcinoma (HCC) generally experience poor outcomes despite current therapies, necessitating the development of alternative treatments. ADP-A2AFP is an investigational autologous T-cell therapy with an affinity-enhanced T-cell receptor (TCR) targeting alpha-fetoprotein (AFP).
METHODS: We describe a phase I, open-label, first-in-human clinical trial of ADP-A2AFP (NCT03132792) in human leukocyte antigen-eligible participants with AFP-expressing HCC (or other tumor) not amenable to transplant/resection who progressed on, were intolerant to, or refused prior systemic therapy. Participants received lymphodepletion chemotherapy (cyclophosphamide 500 mg/m
RESULTS: Twenty-one participants, 20 with advanced HCC and one with gastric hepatoid carcinoma received ≥1 ADP-A2AFP …

Limb-girdle muscular dystrophy D1 (LGMDD1) is a rare, dominantly inherited neuromuscular protein-misfolding chaperonopathy caused by mutations in the Hsp40 co-chaperone DNAJB6, primarily in the glycine-phenylalanine (GF) or J-domains. Currently, no treatments are available, and a challenge in understanding the disease is identifying a specific client protein for DNAJB6 in skeletal muscle. DNAJB6 has homology to the yeast DNAJ family member, Sis1. Our previous research indicated that LGMDD1 GF domain mutants in Sis1 exhibit substrate-specific effects, influenced by Hsp70 activity. Herein, we employed functional assays along with advanced molecular simulation studies to understand the regulatory interdomain interactions in disease-causing mutants of …

BACKGROUND AND AIMS: Deviations from the population mean in sleep duration have been associated with increased risk for developing dyslipidemia and atherosclerotic cardiovascular disease, but the mechanism of effect is poorly characterized. We performed large-scale genome-wide gene-sleep interaction analyses of lipid levels to identify genetic variants underpinning the biomolecular pathways of sleep-associated lipid disturbances and to suggest possible druggable targets.
METHODS: We collected data from 55 cohorts with a combined sample size of 732,564 participants (87 % European ancestry) with data on lipid traits (high-density lipoprotein [HDL-c] and low-density lipoprotein [LDL-c] cholesterol and triglycerides [TG]). Short (STST) and long (LTST) …

Severe aplastic anemia (SAA) is treated with a hematopoietic cell transplant (HCT) in the presence of an HLA-matched sibling donor (MSD) with disease-free survival (DFS) of >90%. In the absence of an MSD, immunosuppressive therapy (IST) can induce remission but concerns for relapsed/refractory disease and clonal hematopoiesis persist. IST failure is an indication for HCT. Modern HCT approaches target barriers such as graft rejection (GR), graft-versus-host disease (GVHD), and transplant-related toxicities. Traditionally, total body irradiation (TBI) inclusive HCT conditioning helps decrease GR, but the use of TBI in children increases concerns for late effects such as malignancies. To describe outcomes …

2020-Current year OA Pubs
BACKGROUND: Immunohistochemistry (IHC) testing is the primary method to determine HER2 status at many institutions, often with reflex to in situ hybridization (ISH). DNA- and RNA- based platforms are emerging for HER-2 assessment. While approved IHC algorithms exist for HER2 scoring in breast and gastric carcinomas, neither has been validated in endometrial cancer. This study seeks to compare them and evaluate patterns of DNA and RNA expression.
METHODS: 263 endometrioid endometrial adenocarcinoma (EEA), 275 serous endometrial carcinoma (SEC), and 214 uterine carcinosarcoma (UCS) specimens were randomly selected. Previously stained HER2 IHC slides underwent blinded review by two board-certified pathologists and …

Multiple myeloma (MM) remains incurable despite advances in treatment options. Although tumor subtypes and specific DNA abnormalities are linked to worse prognosis, the impact of immune dysfunction on disease emergence and/or treatment sensitivity remains unclear. We developed an Immune Atlas of MM by generating profiles of 1,397,272 single cells from the bone marrow (BM) of 337 newly diagnosed participants and characterized immune and hematopoietic cell populations. Cytogenetic risk-based analysis revealed heterogeneous associations with T cells of BM, with 17p13 deletion showing distinct enrichment of a type 1 interferon signature. The disease progression-based analysis revealed the presence of a proinflammatory immune …

Apicomplexan parasites, responsible for toxoplasmosis, cryptosporidiosis and malaria, invade host cells through a unique gliding motility mechanism powered by actomyosin motors and a dynamic organelle called the conoid. Here, using cryo-electron microscopy, we determined structures of four essential complexes of the Toxoplasma gondii conoid: the preconoidal P2 ring, tubulin-based conoid fibers, and the subpellicular and intraconoidal microtubules. Our analysis identified 40 distinct conoid proteins, several of which are essential for parasite lytic growth, as revealed through genetic disruption studies. Comparative analysis of the tubulin-containing complexes sheds light on their functional specialization by microtubule-associated proteins, while the structure of the preconoidal …

2020-Current year OA Pubs
Insulin resistance accompanied by hepatic steatosis is a common complication of obesity. In an effort to identify plasma lipids that could be biomarkers or causes of insulin resistance with steatosis in people with obesity, we evaluated the plasma lipidome in three distinct groups separated by adiposity, hepatic steatosis, and insulin sensitivity, assessed by using the hyperinsulinemic-euglycemic clamp procedure: i) insulin-sensitive lean (ISL, n = 13); ii) insulin-sensitive obese (ISO, n = 14); and iii) insulin-resistant obese with hepatic steatosis (IROS, n = 13). We evaluated 759 complex lipid species in 16 subclasses (including phospholipids, glycerolipids, sphingolipids, acylcarnitines, and cholesteryl esters) …

Fairrfl: Fair And Robust Federated Learning In The Presence Of Selfish Clients, Andrea Augello, Ashish Gupta, Giuseppe Lo Re, Sajal K. Das
Computer Science Faculty Research & Creative Works
Federated Learning (FL) is a paradigm that enables collaborative machine learning without disclosing the local data of the participants. However, in real-world FL deployment scenarios, some unscrupolous clients may alter the training process to skew the global model towards their local optimum, unfairly prioritizing their data distribution. Their influence can degrade overall model performance for normal clients and reduce fairness in the system. We call this novel category of misbehaving clients 'selfish'. This work proposes a Fair and Robust strategy for aggregation in the Federated Learning (FL) server to mitigate the effect of Selfish clients (FairRFL). FairRFL incorporates a novel …

Computer Science Faculty Research & Creative Works
Fairness-aware federated graph neural networks (FedGNNs) necessitate consideration of both the server and the clients. However, fairness-aware methods struggle to enhance dual-perspective (i.e., server and clients) fairness without sacrificing utility due to the distributed learning framework. As a consequence, the utility sacrifices of fairness-aware graph learning methods are even exacerbated in federated frameworks. In this work we propose F3GL, a dual-perspective fairness federated graph learning method that enhances both global (for the server) and local fairness (for clients) while preserving utility. Through theoretical analysis, we delineate the similarity between original sensitive features and those after convolution under different spectra. Our …

Inter-brain synchrony (IBS), measured by hyperscanning, refers to the synchronization of multiple individuals' brain activities during social interactions. Traditional fNIRS-based hyperscanning suffers shortcomings like low spatial resolution and high susceptibility to superficial interference, causing imprecise estimation of IBS in complex social tasks. This study aims to fill the knowledge gap by comprehensively assessing diffuse optical tomography (DOT), an enhanced alternative to fNIRS, can benefit hyperscanning studies of complex social interactions. Sixteen dyads were engaged in both collaborative and individual tangram puzzle tasks, and their brain activities were recorded simultaneously using DOT and fNIRS. We found that DOT demonstrated significantly stronger …

Maladaptive plasticity in the brain may contribute to chronic low back pain (LBP) and underlie the altered postural control of the lumbopelvic musculature that is evident in some individuals with LBP. We recently described an MRI-compatible leg-raise paradigm to measure brain activity associated with lumbopelvic postural control. The objective of this study was to compare brain function in young adults with and without a history of LBP and to determine relationships between brain function, pain, and postural control characteristics. We recruited 55 participants with a history of LBP, who were asymptomatic when studied, and 30 healthy controls. Postural control during …

INTRODUCTION: Alport syndrome features a defective glomerular basement membrane (GBM) due to variants in COL4A3, COL4A4, and COL4A5. The most severe forms, which lack the GBM's collagen α3α4α5(IV) network, progress from hematuria in early childhood to proteinuria, chronic kidney disease, and kidney failure by the age of ∼30. As a monogenic disease without specific treatments, and with podocytes being the only glomerular cells that synthesize collagen α3α4α5(IV), the ability to efficiently deliver genes to Alport podocytes could open up new possibilities for treatment.
METHODS: As a proof-of-concept study, we investigated whether podocytes in X-linked Alport mice were susceptible to transduction …

Optimized Nano-Bilosomes Loaded Ocular Insert As A Promising Approach For Boosting Voriconazole Ocular Bioavailability: In-Vitro, Microbiological, And In-Vivo Assessments, Eman Gomaa
Nanotechnology Research Centre
The eye possesses numerous physiological barriers that significantly limit the absorption of administered drugs, as only < 5 % get through. These barriers restrict drug bioavailability, often necessitating multiple dosing, which can lead to poor patient compliance. The study goal is to efficiently incorporate Voriconazole (VRC), a wide-spectrum antifungal candidate with a short half-life, into stable, biocompatible, non-irritating bile salt nanoparticles (Bilosomes, BLOs) to enhance its ocular delivery. Bilosomes were prepared by the ethanol injection method. Experimental (33) Box–Behnken Design (BBD) was employed; the amount of bile salt, cholesterol, and span-60 were chosen as independent variables, while entrapment efficiency (EE%), cumulative VRC release (Q8h), particle size (PS), zeta potential (ZP), and polydispersity index (PDI) were the dependent variables. The formula of optimization showed EE% (59.04 ± 1.88 %), cumulative release after 8 h (81.35 ± 0.69 %), PS (222.53 ± 2.04 nm), ZP (−72.53 ± 1.75 mV), and PDI (0.225 ± 0.03). It was chemically characterized using DSC and FTIR. Its spherical arrangement was confirmed using TEM. For ophthalmic application, the optimized formula was included in ocular inserts to extend ocular residence time while minimizing dosing frequency. The optimal VRC-loaded bilosomal ocular insert met the acceptable physicochemical criteria, was sterilized using UV radiation for conducting microbiological assay, in-vivo study, and pharmacokinetic analysis. For safety evaluation, an eye irritation study and histopathological examination were conducted. The results confirmed its effectiveness as evidenced by a significantly larger inhibition zone and 8.39-fold enhancement in VRC bioavailability compared to its suspension. These findings support the potential of bilosomes-loaded ocular insert as an effective ocular delivery of VRC.
