_S . boulardii_ is a probiotic yeast widely prescribed in a lyophilized form that determines in human and rat small intestine several effects including endoluminal secretion of enzymes and of polyamines, stimulation of microvillous enzymes, of sIgA ,increased production of the receptor for polymeric immunoglobulins by crypt cells, and enhanced D-glucose uptake.
Aim: The objective of this study was to determine the pathway(s) by which these effects generated by the yeast are transduced into the cell.
Methods: Litters of 6 growing Wistar rats each (30 days post partum) were treated with _S .boulardii_ (50[micro]g per g body wt) or with saline during 72 hours. For each animal, the cytosol was prepared from the whole mucosa... |
