Characterization of gut microbiome profile in children with confirmed wheat allergy.

Background: Food allergies pose serious health risks, including life-threatening anaphylactic reactions, increased morbidity, and reduced quality of life. Wheat allergy is a common concern in Asia. There is growing interest in understanding the potential association between dysregulation of the gut microbiome and the development of food allergies.

Association between Gut Microbiota with Mild Cognitive Impairment and Alzheimer's Disease in a Thai Population.

Background: Mild cognitive impairment (MCI) and Alzheimer's disease (AD) are common in older adults. Much recent work has implicated the connection between the gut and the brain via bidirectional communication of the gastrointestinal tract and the central nervous system through biochemical signaling. Altered gut microbiota composition has shown controversial results based on geographic location, age, diet, physical activity, psychological status, underlying diseases, medication, and drug use.

Tight regulation of the unfolded protein sensor Ire1 by its intramolecularly antagonizing subdomain.

Accumulation of unfolded proteins in the endoplasmic reticulum (ER) accompanies ER stress and causes the type-I transmembrane protein Ire1 (also known as ERN1) to trigger the unfolded protein response (UPR). When dimerized, the core stress-sensing region (CSSR) of Ire1 directly captures unfolded proteins and forms a high-order oligomer, leading to clustering and activation of Ire1. The CSSR is N-terminally flanked by an intrinsically disordered subdomain, which we previously named Subregion I, in Saccharomyces cerevisiae Ire1.
