Molecular characterisation of the underlying mechanisms of pathogen-associated molecular pattern (PAMP) recognition in fish

, 2011
The innate immune response is based upon the activation of a restricted number of genotypic encoded receptors, the pathogen recognition receptors (PRRs). PRRs can be soluble proteins such as plasmatic PGRPs or cell membraneanchored TLRs able to recognize pathogens or their pathogen-associated molecular patterns (PAMPs).

Role of human RNase 7 in neuronal and glial cell models: moving towards an unexpected new functional link

The FEBS Journal, EarlyView.
Human RNase 7 is known to exert antimicrobial activity in epithelial tissues. Here, using SH‐SY5Y and U‐87 MG, neuroblastoma and glioblastoma cell lines, respectively, we found that RNase 7 enhances immune responses to LPS stimulation by reducing the expression of pro‐inflammatory cytokines, nitric oxide, and ROS.

ADAM17 and its proteolytic targets in disease pathogenesis

The FEBS Journal, EarlyView.
ADAM17 as a multifunctional sheddase with contrasting roles across inflammatory, metabolic, cardiovascular, and neoplastic diseases. Through regulated activation by iRhom, iTAP/FRMD8, and tetraspanins, ADAM17 cleaves diverse membrane ligands and receptors, thereby promoting inflammation, fibrosis, obesity, insulin resistance, and tumor progression ...

Inflammation‐Regeneration Axis of Dental Pulp Stem Cells: Wnt/NF‐κB Crosstalk

International Endodontic Journal, EarlyView.
ABSTRACT Background Inflammation critically determines dental pulp regenerative outcomes, with dental pulp stem cells (DPSCs) orchestrating tissue homeostasis through differentiation, self‐renewal and immunomodulation processes dynamically regulated by Wnt/β‐catenin and NF‐κB signaling crosstalk.

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 ...

Cytosolic receptors and signaling in antifungal immunity

The EMBO Journal
The host innate immune system provides the first line of protection against invading microbial pathogens, including fungi. Recognition of fungi by host pattern-recognition receptors (PRRs) is critical for their clearance. PRRs bind to pathogen-associated

Tissue Resident Memory Cells: Friend or Foe?

Immunology, EarlyView.
Tissue‐resident memory T cells (TRM cells) are specialised immune cells in barrier tissues like the lungs, skin and gut, providing rapid host defence and tumour surveillance. Their retention and differentiation are regulated by molecules such as CD69, CD103 and TGF‐β. Dysregulation of TRM cells can lead to chronic activation, driving conditions such as

Extracellular DNA as a Strategy to Manage Vascular Wilt Caused by Fusarium oxysporum in Tomato (Solanum lycopersicum L.) Based on Its Action as a Damage-Associated Molecular Pattern (DAMP) or Pathogen-Associated Molecular Pattern (PAMP)

Plants
Vascular wilt is an important tomato disease that affects culture yields worldwide, with Fusarium oxysporum (F.o) being the causal agent of this infection. Several management strategies have lost effectiveness due to the ability of this pathogen to persist in soil and its progress in vascular tissues.
