Macrophage-induced lung inflammation contributes substantially to respiratory failure during Pneumocystis carinii pneumonia. We isolated a P. carinii cell wall fraction rich in glucan carbohydrate, which potently induces TNF-alpha and macrophage-inflammatory protein-2 generation from alveolar
Persistent activation of macrophages (MP)s into a proinflammatory M1 or anti-inflammatory M2 phenotype plays a role in several pathological conditions, including autoimmune diseases, fibrosis, infections, atherosclerosis and tumor development. The mannose receptor (MR, CD206), expressed at low
Host-mediated recognition of mannose-rich glycans on the surface of pathogens represents an ancient mechanism of innate immune defence. In this study, we demonstrate that the virus strains that differ in the degree of N-linked glycosylation on the globular head of their hemagglutinin glycoprotein
Yeast has a phlogistic effect, and the inflammatory action of 10 brewer's yeast samples fractionated by autolysis and/or destruction of the cell wall was studied in rat hind paw. The yeast samples produced a dose dependent edema when given subcutaneously into the paw. The samples obtained by
Mesoporous silica-based particles are promising candidates for biomedical applications. Here, we address the importance of macrophage activation status for internalization of AMS6 (approx. 200 nm in diameter) versus AMS8 (approx. 2 μm) mesoporous silica particles and the role of different
Mannan, a polysaccharide isolated from yeast binds to C-type lectins of the mannose receptor family, expressed by antigen-presenting cells (APCs) including dendritic cells (DCs) and macrophages. As these receptors mediate endocytosis, they have been targeted with ligands to deliver antigens into
Streptococcus pneumoniae is the cause of a highly lethal form of meningitis in humans. Microglial cells in the brain represent the first line of defense against pathogens, and they participate in the inflammatory response. The cholesterol-dependent cytolysin pneumolysin and the
