Comparison of Transcriptional Signatures of Three Staphylococcal Superantigenic Toxins in Human Melanocytes

Biomedicines, 2022
Staphylococcus aureus, a gram-positive bacterium, causes toxic shock through the production of superantigenic toxins (sAgs) known as Staphylococcal enterotoxins (SE), serotypes A-J (SEA, SEB, etc.), and toxic shock syndrome toxin-1 (TSST-1).

Extrinsic and Intrinsic Charge Transfer at Interfaces of Membrane‐Based Oxide Heterostructures

Advanced Electronic Materials, EarlyView.
Freestanding oxides have emerged as a new opportunity to tailor oxides outside of the typical epitaxial constraints. We present the fabrication of TiO2‐terminated SrTiO3 membranes via direct growth control. We demonstrate competing ionic and electronic charge transfer in LaAlO3/SrTiO3 bilayers using near ambient pressure XPS.

شناسایی ژن مولد توکسین-1 سندروم شوک توکسیک (TSST-1) در جدایه‌های استافیلوکوکوس ارئوس‌های جمع‌آوری شده از نمونه‌های شیرتورم پستان گاو [PDF]

Archives of Razi Institute, 2013
استافیلوکوکوس ارئوس یکی از مهمترین عوامل ایجاد کننده تورم پستان بالینی و تحت بالینی در دام‌های شیری می‌باشد. این باکتری طیف وسیعی از توکسین‌های خارج سلولی و فاکتورهای حدت (TSST-1) تولید می‌کند که در بیماری‌زایی آن نقش دارد.

Psychological stress catalyses free radical-mediated activation of coagulation in humans. [PDF]

J Physiol
Abstract figure legend This study provides the first in vivo evidence that acute psychological stress triggers systemic free radical formation and prothrombotic remodelling of blood clot microstructure. By inducing stress in healthy participants, we observed a significant increase in oxidative stress (A•−), a shortening of the intrinsic pathway of ...

Table_2_Toxin exposure and HLA alleles determine serum antibody binding to toxic shock syndrome toxin 1 (TSST-1) of Staphylococcus aureus.pdf

, 2023
Life-threatening toxic shock syndrome is often caused by the superantigen toxic shock syndrome toxin-1 (TSST-1) produced by Staphylococcus aureus. A well-known risk factor is the lack of neutralizing antibodies.

IgE‐Binding Bacterial Components Not Yet Documented in the Allergen Databases and Their Allergenic Mechanisms: An EAACI Position Paper

Allergy, EarlyView.
ABSTRACT Among bacteria that are associated with the development and/or exacerbation of allergic/atopic diseases, several have been described to produce IgE‐binding components. However, only one bacterial protein, Bac s 1, is currently listed in the official database of the World Health Organization/International Union of Immunological Societies (WHO ...

Local Epidermal Growth Factor Receptor Signaling Mediates the Systemic Pathogenic Effects of Staphylococcus aureus Toxic Shock Syndrome. [PDF]

PLoS ONE, 2016
Secreted factors of Staphylococcus aureus can activate host signaling from the epidermal growth factor receptor (EGFR). The superantigen toxic shock syndrome toxin-1 (TSST-1) contributes to mucosal cytokine production through a disintegrin and ...

The contrasting physiological and subjective effects of chewing gum on social stress [PDF]

, 2012
Uncertainty exists with respect to the extent to which chewing gum may attenuate stress-induced rises in cortisol secretion (Scholey et al., 2009; Smith, 2010; Johnson et al., 2011).
