Microbiome and Tumor Microenvironment Interactions: Advances From Ecological Niches to Precision Oncology

Cancer Nexus, EarlyView.
Tumor‐associated microbiota occupies spatially organized ecological niches and influence cancer progression by reshaping tumor‐cell signaling, metabolism, immunity, stromal remodeling, and therapeutic response. Integrating microbiome‐derived biomarkers, targeted microbial interventions, spatial multi‐omics, longitudinal monitoring, and AI may enable ...

Effects of Aggregatibacter actinomycetemcomitans leukotoxin on neutrophil migration and extracellular trap formation.

, 2016
BACKGROUND: Aggressive periodontitis is associated with the presence of Aggregatibacter actinomycetemcomitans, a leukotoxin (Ltx)-producing periodontal pathogen. Ltx has the ability to lyse white blood cells including neutrophils.

A Serum‐Resistant Plasma Membrane Probe for Real‐Time Visualization of Pathogen‐Induced Epithelial Barrier Dysfunction

Small, EarlyView.
PM580 selectively activates at the plasma membrane while remaining minimally responsive to serum albumin, enabling serum‐compatible, surface‐confined imaging for 24 h, unlike conventional probes that rapidly internalize and lose membrane contrast.

Tools of Aggregatibacter actinomycetemcomitans to Evade the Host Response [PDF]

Journal of Clinical Medicine, 2019
Periodontitis is an infection-induced inflammatory disease that affects the tooth supporting tissues, i.e., bone and connective tissues. The initiation and progression of this disease depend on dysbiotic ecological changes in the oral microbiome, thereby affecting the severity of disease through multiple immune-inflammatory responses.

Oral microbiome and homeostatic regulation of periodontal health: From dysbiosis to precision intervention

VIEW, EarlyView.
Periodontal homeostasis is maintained by coordinated interactions between the oral microbiome and host. Dysbiosis disrupts this ecological balance and contributes to periodontal disease, whereas multi‐omics, artificial intelligence, and microbiome‐based interventions provide emerging opportunities for precision diagnosis, ecological restoration, and ...
