The longterm program of the Laboratory of
Neuroendocrinology, is to study molecular mechanisms of
regulated exocytotic hormone secretion. The function of
a single cell is studied by electrophysiological
techniques of patch-clamping, where the secretory
activity is monitored by changes in membrane
capacitance. Since cytosolic calcium activity is the
trigger of exocytosis in excitable cells, fluorescence
(photometric and imaging) methods are used to measure
changes in cytosolic calcium. Caged calcium photolysis
is used to produce a step change in cytosolic calcium. A
method was developed to quantify the interaction
between a single secretory granule and plasmalemma,
detected as discrete steps in membrane capacitance
(femtofarad steps). A combination of molecular biology
and electrophysiology approach was adopted to inhibit
expression of monomeric GTP-binding proteins. Confocal
microscopy is used to study molecular mechanisms of
regulated exocytosis in endocrine cells, astrocytes and
photoreceptors. We also use confocal microscopy to
evaluate our bioengeneering products.
