Anti-Tissue-Transglutaminase IgA Antibodies Presence Determination Using Electrochemical Square Wave Voltammetry and Modified Electrodes Based on Polypyrrole and Quantum Dots.
Biosensors (Basel)
January 2025
Faculty of Applied Chemistry and Materials Science, National University of Science and Technology Politehnica Bucharest, 313 Splaiul Independentei, Sector 6, 060042 Bucharest, Romania.
A novel electrochemical detection method utilizing a cost-effective hybrid-modified electrode has been established. A glassy carbon (GC) modified electrode was tested for its ability to measure electrochemical tTG antibody levels, which are essential for diagnosing and monitoring Celiac disease (CD). Tissue transglutaminase protein biomolecules are immobilized on a quantum dots-polypyrrole nanocomposite in the improved electrode.

Obesity exacerbates susceptibility to infectious diseases. We investigated the effects of a high-fat diet (HFD) on intestinal immunity, particularly immunoglobulin (Ig)A-producing cells, B-cell activating factor (BAFF), and a proliferation-inducing ligand (APRIL) localization. Mice (4- to 20-weeks old) were fed HFD or standard chow diet, and their jejunum and ileum were fixed using the in vivo cryotechnique.

Division of Gastroenterology and Hepatology, 200 1st Street SW, Rochester, MN, 55905, USA.
Background: Celiac disease (CeD) has shown an association with autoimmune disorders including vitiligo and alopecia areata (AA). Ritlecitinib, a JAK3 and TEC kinase family inhibitor, has been approved for treatment of patients with AA and is in late-stage development for vitiligo. Ritlecitinib inhibits cytotoxic T cells, NK cells, and B cells which play a role in the pathogenesis of CeD.

However, the correlation between other cellular properties of intestinal bacteria and disease has not been explored further, especially for features that are not directly driven by the host immune-system, e.g.
