Strategies for enhancing sensitivity in lateral flow assays

VIEW, EarlyView.
Lateral flow assays (LFAs) are essential for cost‐effective, rapid point‐of‐care diagnostics. However, conventional colourimetric LFAs often lack the sensitivity required for low‐abundance biomarkers. This review evaluates six enhancement strategies: flow modulation, sample preconcentration, advanced reporters, chemical signal amplification, structural

Nucleocapsid and glycoprotein organization in an enveloped virus [PDF]

, 1995
Alphaviruses are a group of icosahedral, positive-strand RNA, enveloped viruses. The membrane bilayer, which surrounds the ∼ 400 Å diameter nucleocapsid, is penetrated by 80 spikes arranged in a T = 4 lattice.

Naturally Occurring ZCCHC3 Variants Modulate Antiretroviral Activity in Cynomolgus Macaques

Microbiology and Immunology, EarlyView.
ABSTRACT Many mammalian cells restrict viral replication by utilizing various host restriction factors. We recently demonstrated that CCHC‐type zinc‐finger‐containing protein 3 (ZCCHC3) suppresses human immunodeficiency virus type 1 (HIV‐1) replication through multiple mechanisms.

Time‐Resolved Multi‐Omics Identify Biomarkers of Immediate Reactions to mRNA Vaccination

Allergy, EarlyView.
We compared early vaccine‐induced immune and metabolic signatures and downstream immunity after second and booster BNT162b2 doses in participants with sARs, ISSRs, or no reactions. Neutrophil mobilization, antiviral programs, and robust anti‐S‐antibody responses occurred across reaction groups.

Role of the Nucleocapsid Domain in HIV-1 Gag Oligomerization and Trafficking to the Plasma Membrane: A Fluorescence Lifetime Imaging Microscopy Investigation

, 2015
International audienceThe Pr55 Gag of human immunodeficiency virus type 1 orchestrates viral particle assembly in producer cells, which requires the genomic RNA and a lipid membrane as scaffolding platforms.

Signs of Cross‐Reactivity Between SARS‐CoV‐2 and Other Coronaviruses in a Pre‐Vaccine Swedish School Setting

Acta Paediatrica, EarlyView.
ABSTRACT Aim This pilot study explored signs of immunological cross‐reactivity between SARS‐CoV‐2 and human coronaviruses (HCoVs) in a Swedish school setting. Methods A cross‐sectional, hypothesis‐generating study was conducted late 2020 before vaccines against COVID‐19 were available.

Innate sensing of HIV-infected cells [PDF]

, 2011
Cell-free HIV-1 virions are poor stimulators of type I interferon (IFN) production. We examined here how HIV-infected cells are recognized by plasmacytoid dendritic cells (pDCs) and by other cells.

Spike specific IgG3 and nucleocapsid IgG response in serum serve as distinguishing immunological markers between SARS-CoV-2 infection and vaccination

Frontiers in Immunology
BackgroundBoth SARS-CoV-2 infection and COVID-19 vaccines elicit immunological responses. However, it is difficult to distinguish responses generated after vaccination versus natural infection.MethodsWe investigated SARS-CoV-2 spike receptor-binding ...
