The Effect of Myrtacine and Celastrol‐Enriched Extract on Cutibacterium acnes Extracellular Vesicles

International Journal of Dermatology, EarlyView.
Myrtacine alone, Celastrol‐enriched extract alone, or the combination of both ingredients were added to the culture medium either before (preventive condition) or after (modulating condition) incubation with C. acnes IA1 extracellular vesicles (EVs) from healthy and acne skin in immortalized keratinocytes (HaCaT cells) and human skin explants.

De novo stolon organogenesis in potato leaf callus elicited by Agrobacterium tumefaciens stimulus

Journal of Integrative Plant Biology, EarlyView.
Agrobacterium tumefaciens triggers stolon regeneration from potato leaf callus independent of T‐DNA insertion, suggesting a strategy to reprogram callus identity and expand the potential of tissue regeneration. ABSTRACT Plant cells can undergo cellular reprogramming, enabling pluripotent callus formation from excised leaves.

Transmission electron microscopy characterisation of Spirulina bioplastics

Journal of Microscopy, EarlyView.
Abstract Plastic pollution is impacting global ecosystem health. Bioplastics made from unprocessed biomass, including whole or fragmented tissues, are one potential solution. They are biodegradable and exhibit competitive mechanical performance. Seaweed and microalgae have gained popularity over the last decade as bioplastic feedstocks due to their ...

Inflammatory and Immunological Basis of Periodontal Diseases

Journal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.

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 ...

A novel peptidoglycan deacetylase modulates daughter cell separation in E. coli.

PLoS Genetics
Peptidoglycan hydrolases facilitate bacterial cell wall growth by creating space for insertion of new material and allowing physical separation of daughter cells.

A Multifunctional β‐Defensin‐3 Mimetic Peptide Modulates Host–Biofilm Interactions and Reduces Bone Loss in Periodontitis

Journal of Periodontal Research, EarlyView.
BDMP, a peptide that can penetrate cells and tissues, offering antimicrobial and anti‐inflammatory effects, has been identified as a potential new therapy for periodontitis. ABSTRACT Aim This study evaluated the potential of a beta‐defensin‐3 mimetic peptide (BDMP), a synthetic cell‐penetrating peptide with antimicrobial and immunomodulatory properties,

Comprehensive and Comparative Transcriptional Profiling of the Cell Wall Stress Response in Bacillus subtilis

Molecular Microbiology, EarlyView.
Transcriptional profiling of the primary cell envelope stress response (CESR) of Bacillus subtilis exposed to a range of cell wall‐targeting antimicrobials, combining RNAseq and high‐resolution tiling arrays. We revealed the complexity of the CESR, the contribution of extracytoplasmic function sigma factors (ECFs) and two‐component signal transduction ...

Toll Like Receptor 4: A Potential Link Between Obesity and Metabolic Diseases

Obesity Reviews, EarlyView.
ABSTRACT Epidemiological evidence shows that obesity increases the risk of developing metabolic diseases. Nevertheless, the mechanisms behind this connection remain underappreciated. The substantial impact of these disorders on global health has led to extensive research efforts aimed at identifying the pathophysiological links between them.
