Perception by plants of so-called microbe-associated molecular patterns (MAMPs) such as bacterial flagellin, referred to as pattern-triggered immunity, triggers a rapid transient accumulation of reactive oxygen species (ROS). We previously identified two cell wall peroxidases, PRX33 and PRX34, involved in apoplastic hydrogen peroxide (H2O2) production in Arabidopsis (Arabidopsis thaliana). Here...

Determination of psychoactive substances (PAS) and/or their metabolites in surface waters is crucial for environmental risk assessment, and disclosure enantiomeric fractions (EF) allows discrimination between consumption, direct disposal, synthesis pathways. The aim this study was to develop validate an indirect method by gas chromatography coupled mass spectrometry (GC–MS) based on derivatizat...

The human gut symbionts in whole and probiotics in particular promote intestinal function and health, partially via modulation of gut associated lymphoid tissue. Molecular basis of microbiota-host interaction is pattern recognition receptors (PRRs) and their ligands, viz., microbe-associated molecular patterns (MAMP). Immunomodulatory effects of probiotics are strain-specific, which is importan...

Plants possess innate immune systems to prevent most potential infections. The ancient and conserved innate immune responses are triggered by microbe-associated molecular patterns (MAMPs) and play important roles in broad-spectrum defenses. However, successful bacterial pathogens evolved type III virulence effectors to suppress MAMP-mediated immunity. To survive, plants further developed highly...

Acidotic conditions in the rumen have been associated with compromised barrier function of ruminal epithelium and translocation microbe-associated molecular patterns (MAMP) such as lipopolysaccharide (LPS). Interaction MAMP may also induce a local proinflammatory response. The aim this study was to evaluate potential response following LPS exposure Ussing chambers, investigate whether affects f...
