Abstract Objectives: The mechanosensitive Ca 2+ion channels, Piezo1, converts the mechanical stimulus into cell signals in a variety of immune cells. However, pathophysiological property Piezo1 oral polymicrobial infectious disease periodontitis is largely unknown. This study investigated role inflammatory and phagocytic reactions by RAW264.7 macrophages response to exposures periodontal pathog...

background: natural killer (nk) cells play an important role in early stages of innate immune responses against viral and tumoral attacks. activation of nk cells by leishmaniasis results in secretion of cytokines such as interferon (ifn)-γ and tumor necrosis factor (tnf)-α, which enhances the phagocytosis and clear­ance of parasite. lipophosphoglycan 3 (lpg3), the leishmania homologous with grp...

Helicobacter pylori is the causative agent for developing gastritis, gastric ulcer, and even gastric cancer. Virulent strains carry the cag pathogenicity island (cagPAI) encoding a type-IV secretion system (T4SS) for injecting the CagA protein. However, mechanisms of sensing this pathogen through Toll-like receptors (TLRs) and downstream signalling pathways in the development of different patho...

Aspergillus fumigatus (A. fumigatus) is one of the most common fungal pathogens of invasive pulmonary aspergillosis (IPA), which may be life threatening in immunocompromised individuals. The dendritic cell-associated C-type lectin receptor (Dectin-1), toll‑like receptor (TLR)-2 and TLR-4 are major pattern recognition receptors in alveolar macrophages that recognize A. fumigatus components. The ...

BACKGROUND/AIMS The bradykinin B2 receptor (BDKRB2) +9/-9 gene polymorphisms have been shown to be associated with the susceptibility and severity of osteoarthritis (OA); however, the underlying mechanisms are unclear. In this study, we investigated the correlation between the BDKRB2 +9/-9 polymorphisms and pro-inflammatory cytokine levels in OA and the molecular mechanisms involved. METHODS ...
