Paracoccidioidomycosis (PCM) is a deep mycosis caused by Paracoccidioides brasiliensis, with high incidence in Brazil. In order to examine the immune response in lesional tissue from patients with PCM, we analyzed cytokines as well as the phenotype of the cell infiltrate. Paraffin-embedded tissue from the oral mucosa of eight patients with the localized adult form (AF) of PCM and from the lymph nodes...
Clinical observations indicate that honey may initiate or accelerate the healing of chronic wounds and has, therefore, been claimed to have anti-inflammatory properties. The aim of this study was to investigate the effects of honey on the activation state of immunocompetent cells, using the monocytic cell line, MonoMac-6 (MM6), as a model.We investigated the effect of each of the three honeys (manuka,...
The aim of this study was to characterize the mediators released by mast cells responsible for IL-8-induced neutrophil migration. It was observed that IL-8 induces a dose-dependent neutrophil migration into peritoneal cavity of rats, but not into air-pouch cavity in which resident mast cells are not present. The transference of peritoneal mast cells to the air-pouch renders this cavity responsive...
Syndecan-1 is expressed on the basolateral surface of columnar epithelium and contributes to wound repair by facilitating increased growth factor binding. Inflammatory bowel disease (IBD) is associated with reduced syndecan-1 expression in areas of inflamed mucosa that is likely to impair mucosal healing. Reduced syndecan-1 expression in IBD may be related to the presence of increased inflammatory...
Surgery is followed by an acute-phase response, including hypothalamo-pituitary-adrenal (HPA)-axis activation and fever. Considering its physiological properties and its behaviour in plasma after stress and surgery, the pro-inflammatory cytokine interleukin (IL)-6 is a putative candidate in eliciting these stress-related symptoms. However, evidence for this hypothesis is lacking. Rats subjected to...
Epidermolysis bullosa acquisita (EBA) is a chronic, uncommon, sub-epidermal blistering disease involving the skin and mucous membranes that heals with scar formation and milia. Collagens, matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) are important components that play an essential role(s) in matrix remodeling during scar formation. However, the possible involvement...
