Collapsin-1/Semaphorin3A (Sema3A) belongs to the secreted type III semaphorins family of axon guidance molecules with chemorepulsive activity, and is suggested to play a major role in navigating axonal networks throughout development into their corre

The distribution of phosphatidylcholine between inner and outer monolayers of rat brain synaptic plasma membrane was investigated by means of a phosphatidylcholine specific exchange protein. About 70% of the total membranal phosphatidylcholine was in

Phospholipases A2 (PLA2) are Ca2(+)-dependent enzymes that are inhibited by EDTA; this inhibition would be expected to be reversed by restoring the Ca2+ concentration. By examining the hydrolysis of synaptosomal phospholipids by PLA2 enzymes, Naja na

Shrinkage and collapse of the neuritic network are often observed during the process of neuronal apoptosis. However, the molecular and biochemical basis for the axonal damage associated with neuronal cell death is still unclear. We present evidence f

Phospholipase A2 (PLA2) toxins act presynaptically to block acetylcholine release and are much more potent and specific in their actions than PLA2 enzymes even though they have lower enzymatic activity. Since their mechanism of action is not complete

The effects of the phospholipase A2 (PLA2) toxins, beta-bungarotoxin and notexin, and the PLA2 enzymes from Naja naja atra and Naja nigricollis snake venoms on the plasma membrane integrity of synaptosomes were examined. Synaptosomes were isolated fr
