Adipocytes treated with neuraminidase show markedly reduced responsiveness to insulin without any alteration in insulin binding.

|
At a concentration of neuraminidase that decreases insulin action by 50%, 23% of total cellular sialic acid content was released.

|
The enzyme action on glucose transport was not due to a nonspecific membrane perturbation because neuraminidase caused only a nonsignificant decrease in the uptake of the amino acid analog alpha-(methylamino)isobutyric acid and had no effect on basal or insulin-stimulated protein synthesis.

|
Insulin binding was slightly increased in neuraminidase-treated cells, yet the shapes of the dose-response curves for insulin stimulation of glucose transport were similar (EC50 = 0.087 +/- 0.010 and 0.082 +/- 0.008 nM for control and treated cells, respectively).

|
Furthermore, liver binding data were not due to cross-reaction of 125I-labeled insulin to the insulinlike growth factor I receptor, and treatment of liver membranes with neuraminidase did not alter the inhibitory effect of the IgGa fraction from patient I-2 on 125I-labeled insulin binding to liver.

|
The more-cathodic intestinal ALP, which comigrated with ALP from colonic mucosa, was completely inhibited by levamisole and converted by neuraminidase to a species with a more basic pI than that of neuraminidase-digested tissue-nonspecific form.

Intestinal variant ALP is most likely composed of intestinal ALP attached to a cellular membrane-binding domain, or may be an artifact produced by neuraminidase incubation.

Also neuraminidase treatment significantly reduced the titre of free (non-immune complexed) anti-T in serum, while selective removal of anti-T by affinity absorption resulted in considerable decrease in the amount of IgA1 that got converted to immune complexes following enzymatic desialylation of serum.
