By flow cytometry it has been shown that in rat thymocytes dying upon gamma-irradiation the reduction in DNA content per cell occurs well before the increase in outer membrane permeability. In contrast, in irradiated Burkitt's lymphoma cells the disturbance of plasma membrane permeability precedes the decrease of DNA content. Genome degradation in dying thymocytes of irradiated or hydrocortisone-treated rats is accounted for by internucleosomal DNA fragmentation. Postirradiation DNA cleavage in the 3 investigated cell cultures is disorderly and is probably caused by the activation of hydrolases in dead cells.

Oral Exposure to Toxin A Aggravates Food Allergy by Intestinal Barrier Destruction, Mast Cell Activation, and Th2-Biased Immune Responses.

State Key Laboratory of Food Science and Resources, Nanchang University, Nanchang 330047, P. R. China.
Food allergy is a complex disease, with multiple environmental factors involved. Considering the regulatory effect of toxin A (Tcd A) on biological processes of allergic reactions, the role of oral exposure to Tcd A on food allergy was investigated. The intestinal permeability and β-hexosaminidase were promoted by Tcd A using the in vitro Caco-2 and HT-29 cells coculture monolayer and bone marrow-derived mast cell (MCs) degranulation model.

Background: Intestinal larva invasion is a crucial step of Trichinella spiralis infection. Intestinal infective larvae (IIL) and their excretory/secretory proteins (ESP) interact with gut epithelium, which often results in gut epithelium barrier injuries. Previous studies showed when T.

Background Aims: Bulevirtide (BLV) is a novel and the only approved treatment option for patients with chronic hepatitis D (CHD). BLV alleviates liver inflammation already early during treatment when only minor HDV RNA changes are observed. We hypothesized that BLV-treatment may influence immune cells in CHD patients and performed a high-resolution analysis of natural killer (NK) cells before and during BLV-therapy.

Purpose: To investigate the effect of Rho-associated protein kinase (ROCK) inhibitor Y27632 on bioenergetic capacity and resilience of corneal endothelial cells (CECs) under metabolic stress.
Methods: Bovine CECs (BCECs) were treated with Y27632 and subjected to bioenergetic profiling using the Seahorse XFp Analyzer. The effects on adenosine triphosphate (ATP) production through oxidative phosphorylation and glycolysis were measured.
Fasting plasma methylglyoxal concentrations are associated with higher numbers of circulating intermediate and non-classical monocytes but with lower activation of intermediate monocytes: the Maastricht Study.

Department of Internal Medicine, Maastricht University Medical Center, Maastricht, 6229ER, the Netherlands.
Purpose: Elevated methylglyoxal (MGO) levels and altered immune cell responses are observed in diabetes. MGO is thought to modulate immune cell activation. The current study investigated whether fasting or post-glucose-load plasma MGO concentrations are associated with circulating immune cell counts and activation in a large cohort study.
