Nasal IgA Provides Protection against Human Influenza Challenge in Volunteers with Low Serum Influenza Antibody Titre

Frontiers in Microbiology, 2017
In spite of there being a number of vaccines, influenza remains a significant global cause of morbidity and mortality. Understanding more about natural and vaccine induced immune protection against influenza infection would help to develop better ...

Blau syndrome NOD2 mutations result in loss of NOD2 cross-regulatory function

Frontiers in Immunology, 2022
The studies described here provide an analysis of the pathogenesis of Blau syndrome and thereby the function of NOD2 as seen through the lens of its dysfunction resulting from Blau-associated NOD2 mutations in its nucleotide-binding domain (NBD). As such,

Mucosal immunity to poliovirus [PDF]

Mucosal Immunology, 2022
A cornerstone of the global initiative to eradicate polio is the widespread use of live and inactivated poliovirus vaccines in extensive public health campaigns designed to prevent the development of paralytic disease and interrupt transmission of the virus.

Endoscopic Management of Gastric Varices: Efficacy and Outcomes of Gluing with N-Butyl-2-Cyanoacrylate in a North American Patient Population

Canadian Journal of Gastroenterology, 2008
BACKGROUND: Gastric variceal bleeding is associated with significant morbidity and mortality in patients with portal hypertension. Outside of North America, gastric variceal injection of N-butyl-2-cyanoacrylate has been shown to be safe and effective ...

Age-Stratified T Cell Responses in Children Infected with Mycobacterium tuberculosis

Frontiers in Immunology, 2017
Tuberculosis (TB) in young children differs from adult TB in that the risk of rapid progression to active TB (aTB) is higher in children than in adults. The reasons for this increased risk are not fully understood. Early differentiation remains difficult

Immuno-Diagnosis of Active Tuberculosis by a Combination of Cytokines/Chemokines Induced by Two Stage-Specific Mycobacterial Antigens: A Pilot Study in a Low TB Incidence Country

Frontiers in Immunology, 2022
Active tuberculosis (aTB) remains a major killer from infectious disease, partially due to delayed diagnosis and hence treatment. Classical microbiological methods are slow and lack sensitivity, molecular techniques are costly and often unavailable ...

Respiratory Viral Infection Alters the Gut Microbiota by Inducing Inappetence

mBio, 2020
Respiratory viral infections are extremely common, but their impacts on the composition and function of the gut microbiota are poorly understood. We previously observed a significant change in the gut microbiota after viral lung infection.

Direct pharmacological AMPK activation inhibits mucosal SARS-CoV-2 infection by reducing lipid metabolism, restoring autophagy flux and the type I IFN response

Journal of Virology
AMP-activated protein kinase (AMPK) plays a central role in regulating cell energy balance. When activated, AMPK suppresses energy-consuming pathways, such as lipid and protein synthesis, while increasing nutrient availability through the activation of ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only
