Calcium (Ca(2+))-dependent endocytosis has been linked to preferential Ca(2+) entry through the L-type (α(1D), Ca(V)1.3) of voltage-dependent Ca(2+) channels (VDCCs). Considering that the(More)
In chromaffin cells, SNARE proteins, forming the basic exocytotic machinery are present in membrane clusters of 500–600 nm in diameter. These microdomains containing both SNAP-25 and syntaxin-1 are(More)
It has been proposed recently that the F-actin cytoskeleton organizes the relative disposition of the SNARE proteins and calcium channels that form part of the secretory machinery in chromaffin(More)
Chromaffin granules are restrained in a dense cortical cytoskeleton before releasing their complex mix of active substances in response to cell stimulation. In recent years, the complex organization(More)
