HmuY proteins of the Porphyromonas genus show diversity in heme-binding properties

Frontiers in Cellular and Infection Microbiology
IntroductionBacteria of the Porphyromonas genus, belonging to the Bacteroidota phylum, colonize various host niches in health and disease. As heme auxotrophs, they rely on heme uptake for iron and protoporphyrin IX.

Porphyromonas gingivalis disrupts hippocampal circadian clock via PI3K/AKT pathway, exacerbating Alzheimer-like pathology. [PDF]

Alzheimers Dement
A graphical abstract is provided to visually summarize the key findings of this study. Abstract INTRODUCTION Periodontal pathogen Porphyromonas gingivalis is epidemiologically linked to Alzheimer's disease (AD), yet how oral infection disrupts the central circadian clock to drive hippocampal neurodegeneration remains unknown.

Harnessing the Therapeutic Potential of Cell Secretomes and Extracellular Vesicles for Craniofacial Regenerative Applications

Journal of Periodontal Research, EarlyView.
The scoping review summarizes the current preclinical and clinical evidence for the use of “cell‐free” therapies in craniofacial (periodontal, bone and soft‐tissue) regeneration. It also aims to highlight key challenges and strategies towards the clinical translation of these therapies.

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.
