Determinants of successful AAV-vectored delivery of HIV-1 bNAbs in early life.

Despite advances in HIV-1 prophylaxis, vertical transmission remains a pressing problem in developing countries. Given the promise of broadly neutralizing antibodies (bNAbs) for HIV-1 prevention, we hypothesized that neonatal delivery of bNAbs using adeno-associated virus (AAV) could provide durable HIV-1 immunity during infancy. Here, using infant rhesus macaques (Macaca mulatta) as a model, we show that a one-time administration of an AAV vector encoding bNAb 3BNC117 at birth led to sustained bNAb expression for more than three years without redosing.

Advancing Health Equity in Europe: Explore, Tailor, Implement, and Evaluate (ETIE)-A Framework of Diversity and Fairness in Pharmacoepidemiologic Research.

Pharmacoepidemiology should represent and benefit populations equitably, embracing diversity and equity, and ensuring fairness. This article describes equity and fairness in pharmacoepidemiology, depicts key diversity domains, and provides an operational framework and call for action to implement diversity and fairness in pharmacoepidemiologic research. To ensure fairness, studies should address diversity and inclusion while providing equal opportunities and benefits for everyone in the target population.

The survival of B cells is compromised in kidney disease.

Antibody-mediated protection against pathogens is crucial to a healthy life. However, the recent SARS-CoV-2 pandemic has shown that pre-existing comorbid conditions including kidney disease account for compromised humoral immunity to infections. Individuals with kidney disease are not only susceptible to infections but also exhibit poor vaccine-induced antibody response.

Tim-3 Is Required for Regulatory T Cell-Mediated Promotion of T Cell Exhaustion and Viral Persistence during Chronic Lymphocytic Choriomeningitis Virus Infection.

Expression of T cell Ig and mucin domain-containing protein 3 (Tim-3) is upregulated on regulatory T cells (Tregs) during chronic viral infections. In several murine and human chronic infections, the expression of Tim-3 is associated with poor control of viral burden and impaired antiviral immune responses. However, the role of Tim-3+ Tregs during persistent viral infections has not been fully defined.

The RNA binding protein Arid5a drives IL-17-dependent autoantibody-induced glomerulonephritis.

Autoantibody-mediated glomerulonephritis (AGN) arises from dysregulated renal inflammation, with urgent need for improved treatments. IL-17 is implicated in AGN and drives pathology in a kidney-intrinsic manner via renal tubular epithelial cells (RTECs). Nonetheless, downstream signaling mechanisms provoking kidney pathology are poorly understood.

Alternatively Spliced Variants of Murine CD247 Influence T Cell Development and Activation, Revealing the Importance of the CD3ζ C-Terminal Region.

CD247, also known as CD3ζ, is a crucial signaling molecule that transduces signals delivered by TCR through its three ITAMs. CD3ζ is required for successful thymocyte development. Three additional alternatively spliced variants of murine CD247 have been described, that is, CD3ι, CD3θ, and CD3η, that differ from CD3ζ in the C terminus such that the third ITAM is lost.

"iNETgrate": integrating DNA methylation and gene expression data in a single gene network.

Integrating multi-omics data in one model can increase statistical power. However, designing such a model is challenging because different omics are measured at different levels. We developed the iNETgrate package (https://bioconductor.

The gut protist Tritrichomonas arnold restrains virus-mediated loss of oral tolerance by modulating dietary antigen-presenting dendritic cells.

Loss of oral tolerance (LOT) to gluten, driven by dendritic cell (DC) priming of gluten-specific T helper 1 (Th1) cell immune responses, is a hallmark of celiac disease (CeD) and can be triggered by enteric viral infections. Whether certain commensals can moderate virus-mediated LOT remains elusive. Here, using a mouse model of virus-mediated LOT, we discovered that the gut-colonizing protist Tritrichomonas (T.

Acute Corneal Transplant Rejection After Severe Acute Respiratory Syndrome Coronavirus 2 mRNA-1273 Vaccination.

Purpose: The purpose of this article was to report a case of full-thickness corneal transplant rejection 3 days after immunization with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Moderna mRNA-1273 vaccine.

Methods: Case Report.

Results: A 51-year-old man with a history of keratoconus and penetrating keratoplasty underwent repeat penetrating keratoplasty for graft failure.

Effectiveness of Mavrilimumab in Viral Infections Including SARS-CoV-2 Infection - A Brief Review.

Hyperinflammation and cytokine storm has been noted as a poor prognostic factor in patients with severe pneumonia related to coronavirus disease 2019 (COVID-19). In COVID-19, pathogenic myeloid cell overactivation is found to be a vital mediator of damage to tissues, hypercoagulability, and the cytokine storm. These cytokines unselectively infiltrate various tissues, such as the lungs and heart, and nervous system.

DNA methylation analysis improves the prognostication of acute myeloid leukemia.

Integration of orthogonal data could provide new opportunities to pinpoint the underlying molecular mechanisms of hematologic disorders. Using a novel gene network approach, we integrated DNA methylation data from The Cancer Genome Atlas ( = 194 cases) with the corresponding gene expression profile. Our integrated gene network analysis classified AML patients into low-, intermediate-, and high-risk groups.

Implementing a sleep technician-supervised and personalized APAP interface fitting session prior to initiation of home APAP therapy improves adherence in patients with obstructive sleep apnea.

Study Objectives: Home automatic positive airway pressure (APAP) therapy is becoming a mainstay treatment of obstructive sleep apnea. It is typically prescribed without any prior supervised titration. Initial experience of APAP treatment dictates subsequent use.

Surface stabilized atorvastatin nanocrystals with improved bioavailability, safety and antihyperlipidemic potential.

Atorvastatin, a favored option for hyperlipidemia exhibits the problem of poor gastric solubility and low absolute bioavailability (12%) along with higher pre-systemic clearance (>80%). Therefore, to circumvent these limitations, atorvastatin nanocrystals were prepared using poloxamer-188 as stabilizer via high pressure homogenization technique followed by lyophilization. Various variables like drug to poloxamer-188 ratio, homogenization cycle, homogenization pressure, type and concentration of cryoprotectant were optimized to achieve uniform nanosized crystals with good dispersibility.

Altered esophageal histamine receptor expression in Eosinophilic Esophagitis (EoE): implications on disease pathogenesis.

Eosinophilic Esophagitis (EoE) is a chronic allergic disorder, whose pathobiology is incompletely understood. Histamine-producing cells including mast cells and basophils have been implicated in EoE. However, very little is currently known about the role of histamine and histamine receptor (HR) expression and signaling in the esophageal epithelium.

Protein-protein interface detection using the energy centrality relationship (ECR) characteristic of proteins.

Specific protein interactions are responsible for most biological functions. Distinguishing Functionally Linked Interfaces of Proteins (FLIPs), from Functionally uncorrelated Contacts (FunCs), is therefore important to characterizing these interactions. To achieve this goal, we have created a database of protein structures called FLIPdb, containing proteins belonging to various functional sub-categories.

Cervical conization complicated by sepsis with lung and liver abscesses.

Background: Extrapelvic infections complicating cervical conization are exceedingly rare.

Case: Seven days after conization, a 44-year-old patient presented with fever and right upper quadrant pain. Pleural effusion and pulmonary and hepatic abscesses were detected.

The effect of a chlorhexidine-based surgical lubricant during pelvic examination on the detection of group B Streptococcus.

Objective: The objective of the study was to estimate whether surgical lubricant used during pelvic examination alters the detection of group B Streptococcus (GBS).

Study Design: We conducted a prospective cohort study of patients undergoing GBS screening at the prenatal clinics of a New York City public hospital. Two specimens were collected from each patient, before and after a pelvic examination with Surgilube (Fougera and Co, Melville, NY), a bacteriostatic surgical lubricant.
