Indoor air pollutants stimulate interleukin-8-specific mRNA expression and protein secretion of alveolar macrophages.
1998
Indoor air pollutants may cause inflammatory changes of the airways and adjacent pulmonary tissue. After phagocytosis of inhaled particles alveolar macrophages (AM) release chemotactic mediators capable of attracting inflammatory cells into the lung tissue. To evaluate these mechanisms further peripheral blood mononuclear cells (PBMNC) and human AM (freshly recovered from the lower respiratory tract) were exposed to the indoor particles Soot FR 101 and Printex 90, the asbestos fiber Chrysotile B, and titanium dioxide (TiO2) at concentrations of 10 or 50 microg/10(6) cells for up to 8 h. The migration of granulocytes into the conditioned supernatants of AM and PBMNC was quantified by chemota…
Capacity of Gentamicin-Treated Pseudomonas aeruginosa to Induce Granulocyte Locomotion
1982
In protection against an invading parasite the host’s granulocytes play an essential role. To exert their defense the phagocytes have to be attracted to the site of parasite invasion. We have shown that Pseudomonas aeruginosa ATCC 27853 and other clinical isolates of this species can induce granulocyte migration, either directly or via generation of chemotactic activity in serum [1].
