1 Role of endogenously derived leukotrienes in the regulation of lysosomal enzyme expression in macrophages exposed to beta 1,3-glucan. Leukotrienes hemoglobin, beta adult major chain Mus musculus
2 The expression of the lysosomal enzyme hexosaminidase has been shown to be stimulated by the exposure of mouse macrophages to beta 1,3-glucan, a particulate component of yeast cell walls and zymosan particles. Zymosan hemoglobin, beta adult major chain Mus musculus
3 Exposure of mouse peritoneal macrophages to particulate beta 1,3-glucan (100 micrograms/ml) was also found to stimulate the production of eicosanoids from both the cyclooxygenase (prostaglandin E2) and 5"-lipoxygenase (leukotriene C4) pathways. Eicosanoids hemoglobin, beta adult major chain Mus musculus
4 Exposure of mouse peritoneal macrophages to particulate beta 1,3-glucan (100 micrograms/ml) was also found to stimulate the production of eicosanoids from both the cyclooxygenase (prostaglandin E2) and 5"-lipoxygenase (leukotriene C4) pathways. Dinoprostone hemoglobin, beta adult major chain Mus musculus
5 Exposure of mouse peritoneal macrophages to particulate beta 1,3-glucan (100 micrograms/ml) was also found to stimulate the production of eicosanoids from both the cyclooxygenase (prostaglandin E2) and 5"-lipoxygenase (leukotriene C4) pathways. Leukotriene C4 hemoglobin, beta adult major chain Mus musculus
6 Collectively these data suggest that the leukotriene products of the 5"-lipoxygenase pathway, LTC4 and LTB4, regulate the expression of lysosomal enzymes by apparently priming macrophages, thereby increasing their sensitivity to triggering agents such as beta 1,3-glucan. Leukotrienes hemoglobin, beta adult major chain Mus musculus
