Cromolyn inhibits assembly of the NADPH oxidase and superoxide anion generation by human neutrophils

The Journal of Immunology. 154:3429-3436
Early and late phase reactions have been observed in asthma; the late phase reaction is characterized by accumulation of inflammatory cells such as neutrophils. Activated neutrophils degranulate and assemble an active NADPH oxidase, which generates s

Bovine parainfluenza-3 (PI-3) virus inhibits oxygen-dependent bacterial killing by phagocytes, a key pulmonary defense, thus predisposing the host to intrapulmonary bacterial superinfection. PI-3 virus inhibited opsonized zymosan or PMA-activated sup

In contrast to its macrophage-activating capacity, IFN-gamma downregulates expression of the macrophage mannose receptor (MMR), which mediates uptake of Candida and other microorganisms. We found that IFN-gamma induced a concentration-dependent incre

The generation of superoxide anion and release of granule contents are essential to the bactericidal function of neutrophils, but may also contribute to host tissue damage during inflammation. In previous studies (J. Immunol. 146:2388), we have demon

Cytosolic free Ca2+ rises in pancreatic beta-cells in response to glucose stimulation and is part of the coupling to insulin secretion. This study evaluates a possible role for cytosolic long chain acyl-CoA esters in modulating Ca2+ handling by clona

Actinobacillus actinomycetemcomitans produces a cytolytic peptide leukotoxin which kills susceptible target cells, including human neutrophils, monocytes, lymphocytes, and HL-60 promyelocytic leukemia cells. Cell death occurs as a consequence of coll

We studied the biochemical basis of phagocytosis of Candida albicans, a serious pathogen, and Candida parapsilosis, which is rarely pathogenic, by human monocytes (Mo) and monocyte-derived macrophages (MDM). Optimal phagocytosis of both species by Mo

Actinobacillus actinomycetemcomitans leukotoxin permeabilized the plasma membrane of HL-60 promyelocytic leukemia cells, resulting in colloid osmotic lysis. These events were associated with efflux of 51chromium (from prelabeled cells), influx of pro

Pancreatic beta-cells contain protein kinase C (PKC) isoforms that may play a role in insulin secretion. Activity of PKC classes (cPKC, nPKC, aPKC) and their regulation by acyl-CoA derivatives was examined in extracts of clonal pancreatic beta-cells
