pubmed:abstractText |
Binding of Escherichia coli heat-stable enterotoxin (STa) to its putative receptor on the brush border membrane of enterocytes is a prerequisite for the induction of diarrhea in infected humans and animals. Humans and animals of different ages vary in their susceptibility to the effect STa, perhaps due to the difference in STa interaction with its intestinal receptor. Flow cytometry was compared to indirect immunofluorescence and 125I-STa binding assays to measure the STa-enterocytes receptor interaction in different age groups of Swiss Webster mice (2-, 7-, 14-day-old). Flow cytometry indicated stronger interaction between STa and its putative receptor on enterocytes from the 2-day-old mice than enterocytes from older mice. 125I-STa-binding assay suggested that the stronger fluorescence intensity on enterocytes from younger mice is due to higher STa receptor density and higher receptor affinity to STa. Flow cytometry is more sensitive quantitative assay to measure the interaction between STa and its intestinal receptor than indirect immunofluorescence microscopy.
