Phenolic exudates from orchid seeds as nutrients chemically attract fungi

Journal of Integrative Plant Biology, EarlyView.
Most orchid species require fungi for natural germination, but the molecular mechanism of this symbiosis is poorly understood. Cremastra appendiculata seeds secrete phenolic acids before fungal contact, acting as nutrient molecules to chemically attract its symbiotic fungus Coprinellus disseminatus.

Liver cirrhosis is associated with altered glucocorticoid metabolism related to disease severity

Journal of Internal Medicine, EarlyView.
Abstract Background Liver cirrhosis (LC) is frequently complicated by adrenal dysfunction; however, whether cirrhosis drives the coordinated, pathway‐specific reprogramming of cortisol metabolism remains unclear. Objectives We aimed to characterize axis‐specific alterations in cortisol metabolism in patients with LC, those with adrenal insufficiency ...

The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

The Oral‐Gut Axis: Bidirectional Interactions Between Microbiome and Diseases

Journal of Periodontal Research, EarlyView.
This study aims to summarize the mechanisms underlying ectopic colonization of the gut by oral pathobionts and the microbial and host factors that regulate this process. ABSTRACT Increased colonization of typically oral microorganisms is frequently observed in the gut mucosa or lumen of individuals with gastrointestinal disorders, including patients ...
