Modes of Transmission of Influenza B Virus in Households

PLoS ONE, 2014
Alors que les virus grippaux A et B peuvent être transmis par des gouttelettes respiratoires, l'importance des petits noyaux de gouttelettes « aérosols » dans la transmission est controversée. À Hong Kong et à Bangkok, en 2008-2011, les sujets ont été recrutés dans des cliniques ambulatoires s'ils avaient une apparition récente de maladie respiratoire ...

Copper‐Driven Epithelial Barrier Disruption: A Novel Mechanism of COPD Acute Exacerbations Mediated by the TNF‐α/ATP7A Axis

Advanced Science, EarlyView.
This study reveals a copper‐driven mechanism of COPD acute exacerbations mediated by the TNF‐α/ATP7A axis. TNF‐α suppresses the copper transporter ATP7A via competitive NF‐κB/CREB1/CBP signaling, resulting in intracellular copper accumulation, mitochondrial oxidative stress, and epithelial barrier disruption.

Influenza A hemagglutinin virus-like particles confer protection against influenza B virus infection

Emerging Microbes and Infections
Influenza A hemagglutinin (HA), neuraminidase, and/or M2e-containing virus-like particles (VLPs) induce immune responses that contribute to protection against multiple influenza A virus subtypes.

Innate Immunocompetent hiPSC‐Derived Neurospheroids Capture Early CNS Responses to rAAV

Advanced Science, EarlyView.
Knowledge of human CNS immune responses to AAV‐based gene therapies remains limited due to the lack of immune‐competent human models. Here, a hiPSC‐derived 3D neuroimmune platform integrating neurospheroids and microglia is established using stirred‐tank bioreactors.

Recovery of an antiviral antibody response following attrition caused by unrelated infection.

PLoS Pathogens, 2014
The homeostatic mechanisms that regulate the maintenance of immunological memory to the multiple pathogen encounters over time are unknown. We found that a single malaria episode caused significant dysregulation of pre-established Influenza A virus ...

A Critical Time Window of Neocortex Modulation for Remote Fear Memory in Rats and Humans

Advanced Science, EarlyView.
This study identifies a delayed consolidation window around 18 h after fear learning in the mPFC essential for remote fear memory. VTA dopaminergic input during this window sustains remote memory in rats, while non‐invasive stimulation of homologous human mPFC at the corresponding time selectively weakens remote but not recent fear memory, revealing a ...

Cryotomography of budding influenza a virus reveals filaments with diverse morphologies that mostly do not bear a genome at their distal end [PDF]

, 2013
Influenza viruses exhibit striking variations in particle morphology between strains. Clinical isolates of influenza A virus have been shown to produce long filamentous particles while laboratory-adapted strains are predominantly spherical.

Pre‐Regenerative Endothelial Cells Empowered by Antler Blood Exosomes Orchestrate Peripheral Nerve Repair

Advanced Science, EarlyView.
The pre‐regenerative vascular niche (PVN) is essential for nerve repair, yet its endothelial blueprint remains unclear. We identified angiogenic ECs (AECs) as the dominant pre‐regenerative subset and found that antler blood–derived exosomes (AB‐EXO) promote repair via IMP3.

Further evidence of the circulation of PMV-4 and influenza viruses with N2 - 1957 enzyme in migratory waterfowls [PDF]

, 1989
I n the years 1980—1984, one paramyxovirus type 4 and 11 influenza viruses were isolated from cloacal swabs collected from migratory waterfowls in Fed. Rep. Germany.

Studies on influenza A virus PB1-F2 protein [PDF]

, 2011
The influenza A virus genome codes for up to 12 proteins. Segment 2 encodes three proteins, the polymerase subunit PB1, a small protein PB1-F2 and an N-terminally truncated version of PB1 called N40. Different functions have been reported for PB1-F2 such
