High intraluminal pressure
WebPMCID: PMC2519219. DOI: 10.1152/ajpheart.00205.2008. Abstract. Previously, we found that high intraluminal pressure leads to production of reactive oxygen species … WebEnterochromaffin cells in control animals without increased luminal pressure contained immunogold-labeled secretory granules in the apical and basal cytoplasm. After intraluminal pressure increased, many apical secretory granules were no longer dense and immunogold particles were localized over the cytoplasmic matrix and microvilli.
