BMJ Open Respiratory Research: Bidirectional relationship between sleep problems and long COVID: a longitudinal analysis of data from the COVIDENCE UK study
ABSTRACT Background Studies into the bidirectional relationship between sleep and long COVID have been limited by retrospective pre-infection sleep data and infrequent post-infection follow-up. We therefore used prospectively collected monthly data to evaluate how pre-infection sleep characteristics affect risk of long COVID and to track changes in sleep duration during the year after SARS-CoV-2 infection. Methods COVIDENCE UK is a prospective, population-based UK study of COVID-19 in adults. We includ...

Nature Biomedical Engineering: Ultrasensitive and long-lasting bioluminescence immunoassay for point-of-care viral antigen detection
ABSTRACT Bioluminescence holds notable promise as a modality in diagnostics due to its high signal-to-noise ratio and absence of incident radiation. However, challenges arise from rapid signal decay and reduced enzyme activity when linked to targeting molecules, limiting its reliability in point-of-care diagnostic applications. Here we introduce the luminescence cascade-based sensor (LUCAS) assay, an enzyme cascade system capable of detecting analytes with ultrahigh sensitivity and prolonged bioluminescence...

Nature Immunology: Mucosal unadjuvanted booster vaccines elicit local IgA responses by conversion of pre-existing immunity in mice
ABSTRACT Mucosal delivery of vaccine boosters induces robust local protective immune responses even without any adjuvants. Yet, the mechanisms by which antigen alone induces mucosal immunity in the respiratory tract remain unclear. Here we show that an intranasal booster with an unadjuvanted recombinant SARS-CoV-2 spike protein, after intramuscular immunization with 1 μg of mRNA–LNP vaccine encoding the full-length SARS-CoV-2 spike protein (Pfizer/BioNTech BNT162b2), elicits protective mucosal immunity by r...

Nature Immunology: Identification of soluble biomarkers that associate with distinct manifestations of long COVID
ABSTRACT Long coronavirus disease (COVID) is a heterogeneous clinical condition of uncertain etiology triggered by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Here we used ultrasensitive approaches to profile the immune system and the plasma proteome in healthy convalescent individuals and individuals with long COVID, spanning geographically independent cohorts from Sweden and the United Kingdom. Symptomatic disease was not consistently associated with quantitative differenc...

ACS Chemical Biology: Neurotoxic Implications of Human Coronaviruses in Neurodegenerative Diseases: A Perspective from Amyloid Aggregation
ABSTRACT Human coronaviruses (HCoVs) include seven species: HCoV-229E, HCoV-NL63, HCoV-OC43, HCoV-HKU1, MERS-CoV, SARS-CoV-1, and SARS-CoV-2. The last three, classified as Betacoronaviruses, are highly transmissible and have caused severe pandemics. HCoV infections primarily affect the respiratory system, leading to symptoms such as dry cough, fever, and breath shortness, which can progress to acute respiratory failure and death. Beyond respiratory effects, increasing evidence links HCoVs to neurological dy...
