Existence of exocytotic hemifusion intermediates with a lifetime of up to seconds in type II pneumocytes.

21 Oct 2009 Exocytosis proceeds through prefusion stages such as hemifusion, but hemifusion is still an elusive intermediate of unknown duration. Using darkfield and fluorescence microscopy in ATII (alveolar type II) cells containing large secretory vesicles ... Read more...

Time-dependent exposure of nicotine and smoke modulate ultrasubcellular organelle localization of dopamine D1 and D2 receptors in the rat caudate-putamen.

29 Sep 2009 The correlation of the subcellular localization of dopamine D(1) and D(2) receptors (DA D(1) R, DA D(2) R) with nicotine addiction has not been studied. We demonstrated the ultrasubcellular organelle localization of DA D(1) and D(2) Rs in the ... Read more...

Dendritic synthesis and release of the neuropeptide galanin: morphological evidence from studies on rat locus coeruleus neurons.

18 Sep 2009 Dendritic synthesis and release of neuropeptides have been demonstrated in hypothalamic neurosecretory neurons. Here we tested whether this mechanism may be applicable to galanin in rat locus coeruleus (LC) neurons. Light and electron microscopic ... Read more...
