Underneath the Gut-Brain Axis in IBD-Evidence of the Non-Obvious.

The gut-brain axis (GBA) plays a pivotal role in human health and wellness by orchestrating complex bidirectional regulation and influencing numerous critical processes within the body. Over the past decade, research has increasingly focused on the GBA in the context of inflammatory bowel disease (IBD). Beyond its well-documented effects on the GBA-enteric nervous system and vagus nerve dysregulation, and gut microbiota misbalance-IBD also leads to impairments in the metabolic and cellular functions: metabolic dysregulation, mitochondrial dysfunction, cationic transport, and cytoskeleton dysregulation.

The application of explants, crypts, and organoids as models in intestinal barrier research.

models are of great importance in advancing our understanding of human diseases, especially complex disorders with unknown etiologies like inflammatory bowel diseases (IBD). One of the key IBD features is the increased intestinal permeability. The disruption of the intestinal barrier can occur due to a destructive inflammatory response involving intestinal cell death.

Phospholipid supplementation inhibits male and female odor discrimination in mice.

Dietary phospholipids (PLs) are promising supplements that are commonly found as natural food ingredients and emulsifier additives. The present study aimed to evaluate the effect of major PLs found in food supplements on social behavior in mice. In this study, the effect of short-term high dietary PL content was studied in terms of social odor discrimination and social interactions with male and female intruders in male mice.

Investigating social communication in mice: A two-intruders test approach.

Understanding the complex dynamics of social communication behaviors, such as exploration, communication, courtship, mating, and aggression in animal models, is crucial to reveal key neural and hormonal mechanisms underlying these behaviors. The two-intruders test is designed to investigate residents' behavior toward both male and female intruders within the home cage of the test male. During this test imitating natural conditions, several aspects of social interaction were investigated: Exploration, courtship, mating, and aggressive behavior.
