Plasmatic profiles of cytokines/chemokines, glial fibrillary acidic protein (GFAP) and MRI brain damage in neonates with hypoxic ischemic encephalopathy (HIE).

Background: Perinatal hypoxia triggers the release of cytokines and chemokines by neurons, astrocytes and microglia. In response to hypoxia-ischemia resting/ramified microglia proliferate and undergo activation, producing proinflammatory molecules. The brain damage extension seems to be related to both the severity of hypoxia and the balance between pro and anti-inflammatory response and can be explored with neuroimaging.

Mannose Binding Lectin, S100 B Protein, and Brain Injuries in Neonates With Perinatal Asphyxia.

Perinatal asphyxia triggers an acute inflammatory response in the injured brain. Complement activation and neuroinflammation worsen brain damage after a systemic ischemia/reperfusion insult. The increase of mannose binding lectin (MBL) during asphyxia may contribute to the brain damage, via activation of the complement lectin pathway.

β2-Agonist clenbuterol hinders human monocyte differentiation into dendritic cells.

Clenbuterol (CLB) is a beta2-adrenergic agonist commonly used in asthma therapy, but is also a non-steroidal anabolic drug often abused in sport doping practices. Here we evaluated the in vitro impact of CLB on the physiology and function of human monocytes and dendritic cells (DCs), instrumental in the development of immune responses. We demonstrate that CLB inhibits the differentiation of monocytes into DCs and this effect is specific and dependent on β2-adrenergic receptor (AR) activation.

Two wheat decapeptides prevent gliadin-dependent maturation of human dendritic cells.

Celiac disease (CD) is a small intestinal enteropathy, triggered in susceptible individuals by the ingestion of dietary gluten. Dendritic cells (DC) are instrumental in the generation and regulation of immune responses and oversee intestinal immune homeostasis promoting and maintaining oral tolerance to food antigens. The aim of this study was to monitor the effect of peptic-tryptic digest of gliadin (PT-gliadin) on the maturation of human monocyte-derived DC and the impact of pDAV and pRPQ decapeptides in the modulation of PT-gliadin-induced phenotypic and functional DC maturation.

Diversity of oat varieties in eliciting the early inflammatory events in celiac disease.

Purpose: Celiac disease (CD) is an autoimmune enteropathy, triggered by dietary gluten. The only treatment is a strict gluten-free diet. Oats are included in the list of gluten-free ingredients by European Regulation, but the safety of oats in CD is still a matter of debate.
