BLIMP‐1 and CD39 expression define human effector memory regulatory T cells in blood and recall responses to viruses

Immunology &Cell Biology, EarlyView.
This study found that BLIMP‐1 is highly expressed in activated effector/memory human regulatory T cells, especially CD39+ Tregs, where it is associated with increased IL‐10 production and a conserved phenotype across blood and lung tissues during immune responses such as SARS‐CoV‐2 infection.

T cell-mediated lethal shock triggered in mice by the superantigen staphylococcal enterotoxin B: critical role of tumor necrosis factor

Journal of Experimental Medicine, 1992
Because mice are more resistant than humans to the pathogenic effects of bacterial toxins, we used D-Galactosamine- (D-Gal) sensitized mice as a model system to evaluate potential toxic shock symptoms triggered by the superantigen staphylococcal ...

Mast Cells in Host Defense Against Cutaneous Staphylococcus aureus Infection

Immunology &Cell Biology, EarlyView.
Impact of S. aureus epicutaneous sensitization models on mast cell function in vivo. D. farinae and Staphylococcal enterotoxin B (SEB) activate Trpv1+ Tac1+ nociceptors to trigger the release of substance P (SP), which promotes mast cell degranulation through Mrgprb2. S.

A Single-Stranded DNA Aptamer That Selectively Binds to Staphylococcus aureus Enterotoxin B

PLoS ONE, 2012
The bacterium Staphylococcus aureus is a common foodborne pathogen capable of secreting a cocktail of small, stable, and strain-specific, staphylococcal enterotoxins (SEs).

Immune Consequences of Metabolic Syndrome and Its Treatment: A Cytokine Perspective

Immunology, EarlyView.
Peripheral blood mononuclear cells (PBMCs) from individuals with metabolic syndrome (MetS) who were not using glucose‐and/or lipid lowering medication (GLLM) exhibited a broader cytokine production profile after in vitro antigen‐specific stimulation than PBMCs from individuals with MetS using such medications and from healthy donors.

Serotypic and Genomic Diversity of Vibrio anguillarum in Rainbow Trout Farms in Turkey: Implications for Vibriosis Control and Vaccine Candidate Selection

Journal of Fish Diseases, EarlyView.
ABSTRACT Outbreaks of vibriosis caused by Vibrio anguillarum are a persistent constraint on rainbow trout (Oncorhynchus mykiss) aquaculture. However, information on the population structure of field strains in Turkey has been lacking. Here, we report the first systematic serotypic, proteomic, and genomic characterization of 23 V.

Isolation of a Highly Thermal Stable Lama Single Domain Antibody Specific for Staphylococcus aureus Enterotoxin B

BMC Biotechnology, 2011
BackgroundCamelids and sharks possess a unique subclass of antibodies comprised of only heavy chains. The antigen binding fragments of these unique antibodies can be cloned and expressed as single domain antibodies (sdAbs).

Immunogenicity and Protective Efficacy of the First Autogenous Aeromonas hydrophila Vaccine for Piaractus brachypomus

Journal of Fish Diseases, EarlyView.
ABSTRACT Aeromonas hydrophila is a major zoonotic bacterial pathogen responsible for haemorrhagic septicemia, substantial economic losses in aquaculture and increasing antimicrobial resistance among field isolates. It is also one of the main bacterial species associated with mortality outbreaks in pirapitinga, Piaractus brachypomus, culture in the ...
