Targeted Next-Generation Sequencing of Cell-Free DNA to Detect -Immunoglobulin Translocation and Epstein-Barr Virus DNA in Plasma of Burkitt Lymphoma Patients in East Africa.
JCO Glob Oncol
January 2025
University of Oxford, Oxford, United Kingdom.
Purpose: Epstein-Barr virus (EBV)-positive Burkitt lymphoma (BL) affects children in sub-Saharan Africa, but diagnosis via tissue biopsy is challenging. We explored a liquid biopsy approach using targeted next-generation sequencing to detect the -immunoglobulin (-Ig) translocation and EBV DNA, assessing its potential for minimally invasive BL diagnosis.
Materials And Methods: The panel included targets for the characteristic -Ig translocation, mutations in intron 1 of , mutations in exon 2 of , and three EBV genes: EBV-encoded RNA (EBER)1, EBER2, and EBV nuclear antigen 2.
Single-cycle parainfluenza virus type 5 vectors for producing recombinant proteins, including a humanized anti-V5 tag antibody.

Parainfluenza virus type 5 (PIV5) can cause either persistent or acute/lytic infections in a wide range of mammalian tissue culture cells. Here, we have generated PIV5 fusion (F)-expressing helper cell lines that support the replication of F-deleted viruses. As proof of the principle that F-deleted single-cycle infectious viruses can be used as safe and efficient expression vectors, we have cloned and expressed a humanized (Hu) version of the mouse anti-V5 tag antibody (clone SV5-Pk1).

Alzheimers Dement
December 2024
MRC Unit for Lifelong Health & Ageing at UCL, London, United Kingdom.
Background: Associations of common infections with Alzheimer's disease have been reported, but potential mechanisms underlying these relationships are unclear. A hypothesised mechanism is amyloid-beta (Aβ) aggregation as a defense mechanism in response to infection, with subsequent tau accumulation. However, no studies have assessed associations of infections with cerebral Aβ and tau pathology in vivo.

Alzheimers Dement
December 2024
University of Colorado School of Medicine, Aurora, CO, USA.
Background: Varicella zoster virus (VZV) reactivation, manifesting as herpes zoster, increases dementia risk. Herein, we review the literature supporting the biological plausibility of VZV contributing to AD pathologies and examine the unique ability of VZV to induce amylin that has been found in blood vessels and parenchyma of AD patients.
Method: We conducted a literature review on VZV and dementia to elucidate a potential model for how VZV reactivation intersects with AD.
Background: Hallmark features of AD are well defined, however, the generation of in vitro models of sporadic AD poses a significant challenge due to the complex, undefined etiology and slow progression of this disease. Herpes simplex virus type I (HSV-1) is a pathogen that is gaining increasing attention as a potential causative agent in AD pathogenesis. HSV-1 is a DNA virus that typically resides throughout the peripheral nervous system in a latent state.
