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

open access: yesInternational 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.

The opsonizing ligand on Salmonella typhimurium influences incorporation of specific, but not azurophil, granule constituents into neutrophil phagosomes. [PDF]

open access: yes, 1989
Phagosomes were purified from human neutrophils ingesting Salmonella typhimurium opsonized with adsorbed normal human serum or with rabbit IgG. Constituents within the phagosome were endogenously labeled by supplying the cells with 125INa during ...

Biomolecular Changes Upon Ablative Laser Therapy of the Skin: A Scoping Review

open access: yesInternational Journal of Dermatology, EarlyView.
(Fractional) ablative laser therapy results in a wound healing response characterized by an inflammatory phase, dermal matrix degradation, and remodeling, collagenesis and elastogenesis. This is characterized by an increase in metalloproteinases, collagen type I, III, VII, and tropoelastin.

Killing of Staphylococci by θ-Defensins Involves Membrane Impairment and Activation of Autolytic Enzymes

open access: yesAntibiotics, 2014
θ-Defensins are cyclic antimicrobial peptides expressed in leukocytes of Old world monkeys. To get insight into their antibacterial mode of action, we studied the activity of RTDs (rhesus macaque θ-defensins) against staphylococci.

Prognostic Significance of the Pretreatment Neutrophil‐to‐Lymphocyte Ratio and Tumor‐Associated Neutrophils in Head and Neck Squamous Cell Carcinoma: Systematic Review and Meta‐Analysis

open access: yesJournal of Oral Pathology &Medicine, EarlyView.
ABSTRACT Objectives The prognostic significance of the neutrophil‐to‐lymphocyte ratio (NLR) and tumor‐associated neutrophils (TANs) in head and neck squamous cell carcinoma (HNSCC) remains a subject of considerable research interest. This systematic review and meta‐analysis aimed to evaluate the relationship between pretreatment NLR and TANs and ...

Genetic Susceptibility to Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Aim: The aim of this narrative review was to identify genes carrying risk alleles associated with an increased risk of periodontitis and to place them in a biological context. Methods: The literature was reviewed based on predefined criteria. Results: The identified genes largely fall into functions linking immune response with tissue repair. The genes

Inflammatory and Immunological Basis of Periodontal Diseases

open access: yesJournal 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.

Keratinocytes from human skin respond as typical immune cells after the stimulation with _Trichophyton rubrum_ [PDF]

open access: yes, 2007
_Trichophyton rubrum_ is the main agent causing dermatophytosis (1). Keratinocytes are considered to be the first physical barrier of defense against pathogens (2). But not only a physical barrier.
