Intrinsic gland cells of the corpus cardiacum
of Locusta synthesize AKH, and release it into the haemolymph shortly after onset of flight. AKH stimulates the release of diacylglycerol β the fuel for the flight muscles β from the fat body.
The peak of haemolymph AKH is reached after about 30 min flight. Release of AKH mainly occurs from short processes of the gland cells, by means of exocytosis.
It may be expected that this release is followed
by compensatory re-uptake of membrane
material by means of endocytosis near the site of exocytosis. To get information on the location of endocytotic activity
and on the intracellular endocytotic pathway, the uptake of the tracer
horse-radish peroxidase (HRP) by the
gland cells in flying and in resting locusts
was studied electron microscopicall
