WONG; Per-Olof HASSELGREN Interleukin-1β (IL-1β) increases the production of complement component C3 in enterocytes. Heat shock regulates the response to cytokines and other inflammatory...

...J. Colyer; P. J. Kumar; N. M. Waldron; M. L. Clark; M. J. G. Farthing 1. Binding of 125 I-crude gluten digest (Frazer's fraction III, FF-III) and 125 I-concanavalin A (Con A) to isolated rat enterocytes and of 125 I-FF-III to human enterocytes was investigated. 2. Specific binding of 125 I-FF-III...

...J. M. P. Hopkins; T. J. Peters 1. 59 Fe-labelled ferric chloride was introduced into tied loops of guinea-pig jejunum. 2. After 5–30 min the loop was removed, the enterocytes were isolated, homogenized and subjected to analytical subcellular fractionation. 3. Uptake of 59 Fe was extremely rapid...

...R. M. Batt; G. Wells; T. J. Peters 1. Enterocytes, isolated from the proximal jejunum and distal ileum of normal and prednisolone-treated rats, were homogenized and fractionated by isopycnic centrifugation on sucrose density gradients. The distributions of marker enzymes for the principal...

...R. M. Batt; T. J. Peters 1. Enterocytes, isolated from the proximal jejunum and distal ileum of the rat, were homogenized and their organelles separated by isopycnic centrifugation on continuous sucrose density gradients. The distributions of marker enzymes for the principal organelles, RNA...

... in the ileum. The Michaelis constant for galactose was higher in the jejunum than in the ileum. 6. Enterocytes were isolated from perfused segments and quantified by DNA assay with a correction for yield. In this manner, the absorptive capacity per enterocyte was calculated. 7. The maximum absorptive capacity...

... was significantly greater in both the jejunum and the ileum of the steroid-treated animals. This was due to an increase in carrier-mediated transport in the individual enterocytes and not to a change in the cell population. The Michaelis constant for galactose was not significantly altered by prednisolone. 3...
