Mast Cells in Host Defense Against Cutaneous Staphylococcus aureus Infection

Immunology &Cell Biology, EarlyView.
Impact of S. aureus epicutaneous sensitization models on mast cell function in vivo. D. farinae and Staphylococcal enterotoxin B (SEB) activate Trpv1+ Tac1+ nociceptors to trigger the release of substance P (SP), which promotes mast cell degranulation through Mrgprb2. S.

Innate Immune Activation Is a Strong Suppressor of CCL22 and Impedes Regulatory T Cell–Dendritic Cell Interaction

Immunology, EarlyView.
During homeostasis, CCL22 is secreted by dendritic cells (DC), which mediate contacts between regulatory T cells (Treg) and DC to maintain immune balance. Activation of innate immunity via microbes or pattern recognition receptor (PRR) agonists induces the secretion of several soluble factors (e.g., type I and II interferons, IL‐10), which mediate ...

MyD88‐Family Adaptors: Compartmentalised Signalling and Non‐Immune Functions

Immunology, EarlyView.
MyD88‐family adaptors coordinate receptor‐ and compartment‐specific innate immune signalling across plasma membrane and endosomal pathways. At the plasma membrane, TIRAP/MAL supports MyD88‐dependent signalling downstream of TLR2 and TLR4, whereas endosomal TLR7, TLR8 and TLR9 recruit MyD88 directly.

Evaluation of Methods for Identifying Human Monocytes by Flow Cytometry: TLR2 May be an Optimal Marker

Immunology, EarlyView.
Monocytes play crucial roles in the pathobiology of a wide range of medical conditions, including infection, autoimmunity, cardiovascular disease and malignancies. Studies using flow cytometry revealed the complexity of monocyte biology, including the identification of three human monocyte subsets: classical (CD14pos CD16neg), intermediate (CD14pos ...

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

Stem Cells From Dental Pulp, Periodontal Tissues, and Other Oral Sources: Biological Concepts and Regenerative Potential

Journal of Periodontal Research, EarlyView.
A graphical abstract recapping the different sources of dental, periodontal, and other oral‐derived mesenchymal stromal cells (MSCs) and their regenerative mechanisms and potentials. The review's article findings bridge fundamental biological science with translational advances, highlighting the significance of MSCs in craniofacial regenerative ...

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 ...

Role of TLR2 rs5743708 and dectin-1 rs16910526 polymorphisms in susceptibility to fungal infections in COVID-19 patients

Introduction: The progression of fungal co-infection with COVID-19 depends on the patient's genetic innate immunity. Our goal is to understand the connection between the single nucleotide polymorphisms (SNPs) rs5743708 and rs16910526 in the toll-like ...
