Allergic Sensitization to Inhalant Allergens in the Upper Respiratory Tract—the B Cell Side

Allergy, EarlyView.
ABSTRACT Allergic diseases are on the rise worldwide, driven by respiratory epithelial barrier dysfunction that promotes sensitization to inhalant allergens such as pollen, dust mites, pet dander, and fungal spores. These antigens trigger IgE‐mediated immune responses that lead to diseases such as allergic rhinitis (AR) and asthma.

Different Types of Cell Death Induced by Enterotoxins

Toxins, 2010
The infection of bacterial organisms generally causes cell death to facilitate microbial invasion and immune escape, both of which are involved in the pathogenesis of infectious diseases.

Autosomal Dominant Hyper‐IgE Syndrome Patients Retain IL10‐Producing preTh17‐Cells That Are Activated by Opportunistic Pathogens and Support IgE Production

Allergy, EarlyView.
IL‐10 producing CCR6+Th‐cells are central memory T‐cells that express ROR‐γt and differentiate to Th17‐cells via an autocrine loop of STAT3‐activating cytokines (preTh17). STAT3‐deficient AD‐HIES patients lack Th17‐ and Tfh17‐cells but retain preTh17‐ and Th1/17‐cells.

Characterization of Enterotoxigenic Bacillus cereus sensu lato and Staphylococcus aureus Isolates and Associated Enterotoxin Production Dynamics in Milk or Meat-Based Broth

Toxins, 2017
Bacillus cereus sensu lato species, as well as Staphylococcus aureus, are important pathogenic bacteria which can cause foodborne illness through the production of enterotoxins.

Mitogenicity of formalinized toxoids of staphylococcal enterotoxin B [PDF]

Infection and Immunity, 1975
Staphylococcal enterotoxin B is a potent mitogen for mouse and human lymphocytes. Mitogenic activity was retained after detoxification of the enterotoxin by formaldehyde at pH 5.0, 7.5, OR 9.5. The most active toxoid (pH 7.5) was separated into a monomeric, a dimeric, and a polymeric fraction (1 x 10(5) to 3 x 10(5) molecular weight) by gel filtration,

Staphylococcus aureus Augments Epithelial Skin Barrier Damage Through T Cell Activation in Cutaneous T Cell Lymphoma

Allergy, EarlyView.
Staphylococcus aureus, commonly colonising CTCL patients, augments skin barrier dysfunction. Staphylococcal enterotoxins induce T‐cell release of barrier‐repressing cytokines (IL‐4, IL‐13, IL‐22, OSM). Cytokine signalling drives JAK‐dependent downregulation of filaggrin and loricrin in keratinocytes. Antibiotic‐mediated eradication of S. aureus induces

Prevalence of six genes encoding enterotoxins production of Staphylococcus aureus isolated from white-brined-cheese by multiplex PCR [PDF]

Bihdāsht-i Mavādd-i Ghaz̠āyī, 2014
Isolation, identification and grouping of Staphylococcal enterotoxins in milk is of great importance since these toxins are considered as a major potential source of human illness.

Targeting the microbiota‐miRNA‐protease axis: A new therapeutic avenue in melanoma

The FEBS Journal, EarlyView.
Modulation of extracellular matrix (ECM) turnover is central to melanoma progression and metastasis, driven largely by ECM proteases. This review highlights the epigenetic regulation of ECM proteases by microRNAs and their roles in melanoma growth, invasion, and immune modulation.

Blood Immunopathology of Tuberculosis Patients Disrupts Monocyte‐Dependent T‐Cell Activation and Cytokine Expression

Immunology, EarlyView.
TB serum selectively disrupts monocyte‐dependent PHA T cell activation and cytokines associated with proliferation while preserving SEB T cell and Pam3/PHA monocyte cytokine responses. ABSTRACT Pulmonary tuberculosis in humans is characterised by features of immunopathology, which influence both antimycobacterial therapy and the long‐term prognosis. In

Endogenous HLA-DQ8αβ programs superantigens (SEG/SEI) to silence toxicity and unleash a tumoricidal network with long-term melanoma survival

Journal for ImmunoTherapy of Cancer, 2020
Background As the most powerful T cell agonists known, superantigens (SAgs) have enormous potential for cancer immunotherapy. Their development has languished due to high incidence (60%–80%) of seroreactive neutralizing antibodies in humans and tumor ...
