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 ...

Biomarkers Correlating With the Development of Oral Squamous Cell Carcinoma From Leukoplakia

Oral Diseases, EarlyView.
ABSTRACT Background We assessed protein biomarkers expressed in oral leukoplakia (OL) that are associated with the risk of transformation into oral squamous cell carcinoma (OSCC). Methods Tissue sections of OL transforming into OSCC (leuko‐ca), the corresponding OSCC and OL that did not progress to OSCC (leuko‐nonca) were analyzed with global relative ...

Pediatric Langerhans Cell Histiocytosis Presenting With Bilateral Parotid Gland Swelling and Cystic Lung Disease: A Case Report and Literature Review

Pediatric Dermatology, EarlyView.
ABSTRACT Langerhans cell histiocytosis (LCH) is a neoplastic process originating from immature myeloid precursor cells. In this report, we describe a case of a 17‐month‐old with scaling of the scalp and swelling of the bilateral parotid glands who developed acute respiratory distress.

Illuminating Connections: Exploring the Dynamic Relationship Between Phototherapy and the Skin

Pediatric Dermatology, EarlyView.
ABSTRACT The neonatal period represents a critical window for skin barrier maturation, microbial colonization, and immune development. As such, early‐life exposures may exert lasting effects on dermatologic and systemic health. A common early‐life exposure is blue light phototherapy (BLP), a life‐saving treatment for neonatal hyperbilirubinemia ...

Cis‐urocanic acid formation following far‐UVC exposure and associated signaling responses in keratinocytes

Photochemistry and Photobiology, EarlyView.
Far‐UVC (200–235 nm) has emerged as a safe and effective indoor disinfection tool, but effects on skin immunomodulation remain unclear. This study demonstrates that 222 nm far‐UVC converts trans‐urocanic acid (UCA) to its biologically active cis isomer at levels comparable with solar radiation. In keratinocytes, far‐UVC alone caused modest increases in

Phototherapies mediated by metallic nanoparticles and near‐infrared radiation in skin cancer: A systematic review

Photochemistry and Photobiology, EarlyView.
Recent studies demonstrate that near‐infrared (NIR—750–980 nm)‐mediated photodynamic (PDT) and photothermal (PTT) therapies, combined with metallic nanoparticles (MNPs), show promising results against skin cancer, particularly melanoma, in both in vitro and in vivo models.

The role of acquired host immunity in periodontal diseases

Periodontology 2000, EarlyView.
Abstract The aim of this narrative review is to relate the contribution of European researchers to the complex topic of the host immune system in periodontal disease, focusing on acquired immunity. Other chapters in this volume will address the genetics and autoantibody responses and other forms of immunity to periodontal disease.

Decoding host–microbial dynamics in peri‐implantitis: Ecosystem‐specific experimental models

Periodontology 2000, EarlyView.
Abstract Background Peri‐implantitis is an inflammatory disease arising within a unique host–microbial–biomaterial ecosystem. Unlike periodontitis, peri‐implant tissues lack a periodontal ligament and epithelial junction integrity and interface with metal oxides on titanium surfaces.
