Rat hippocampal neurons in dispersed cell culture. Activity-related redistribution of presynaptic proteins at the active zone. Similar co-IP experiments were carried out before and at the end of the LatA treatment, using the final supernatant i. Their intracellular actin-rich foci, already visible during the first minute of recovery, increased in size and number thereafter, becoming quite evident between 10 and 20 min, exhibiting continuous random movements, and pushing out and rolling beneath the cell surface. The establishment of polarity by hippocampal neurons in culture.

B Length distribution of the filaments shown in A. NACP, a protein implicated in Alzheimer’s disease and learning, is natively unfolded.

Actin filaments are involved in the transport of clear and dense-core vesicles along the axon and in their clustering at the plasma membrane sites where exocytosis takes place.

α-Synuclein and Its A30P Mutant Affect Actin Cytoskeletal Structure and Dynamics

Figure 7 B shows the values of the cell area at different times during LatA incubation and washout. Notice in the top row the appearance of lamellipodia guiding the cell movement during wash out of LatA; in the low bottom row the appearance, already at 2 min, of large subplasmalemma GFP-actin aggregates persisting up to the end of the experiment.

In the A30P Syn-expressing cells, the cytoskeleton, already disrupted at rest, during recovery from LatA exhibited a number of discrete, subplasmalemma puncta, composed by a core of Vvideo synuclein surrounded by a shell of compacted actin defined from hereon as actin-rich foci.

B Quantification of total fluorescence from five different fields of two independent experiments. Mice lacking alpha-synuclein display functional deficits in the nigrostriatal dopamine system. Alpha-synuclein overexpression in oligodendrocytic cells results in impaired adhesion to fibronectin and cell death.

viveo Data were deconvoluted and the maximum intensity projections along the Z-axis were performed with the SoftWoRx software Applied Precision.

E on June 24, Neural activity controls the synaptic accumulation of alpha-synuclein. Figure 4 A shows filamentous and soluble fractions of actin separated by high-speed centrifugation, in either the absence or presence of LatA.

Monolayers were then scratched along single lines with a micropipette tip, and the distance covered by the cells in the scratched space was measured at various time points. These changes in shape were accompanied by movement of the cell.

Alpha-synuclein cooperates with CSPalpha in preventing neurodegeneration. Distribution of phosphoneuroprotein 14 PNP 14 in vertebrates: During the progression of Parkinson’s disease PDthe dopaminergic neurons of the substantia nigra, pars compacta accumulate proteinaceous inclusion bodies, the Lewy bodies Dawson and Dawson, before undergoing degeneration.

The quantifications for neuronal a30 experiments were made using a custom-made macro in ImageJ. Powering membrane traffic in endocytosis and recycling. A common threshold was applied to all images in order to exclude background fluorescence. After 30 min in the incubator, the cells were monitored by phase-contrast microscopy, with images taken at 0, 18, 24, and 48 h.

α-Synuclein and Its A30P Mutant Affect Actin Cytoskeletal Structure and Dynamics

The same protocol was used for stably transfected N2A clones. Beads were washed as above. Their intracellular actin-rich foci, already visible during the first videi of recovery, increased in size and number thereafter, becoming quite evident between 10 and 20 min, exhibiting continuous random movements, and pushing out and rolling beneath the cell surface.

Rapid remodeling of the actin cytoskeleton is also required for cell adhesion and neurite outgrowth. Moreover, actin fibers form a dense filamentous network beneath the plasma membrane, which is reorganized upon cell stimulation to allow the access of vesicles to fusion sites. Lauring Columbia University, New York.

Experiments carried out in primary cultures of hippocampal neurons document the relevance of our results also for neuronal cells.

Figure 7 C illustrates the cells mobility, assayed by taking the center of the nucleus as a reference point. S, supernatant of the P2 centrifugation half of the supernatant was loaded. Bacteria were induced during the exponential phase with 0.

Protein expression in a Drosophila model of Parkinson’s disease. Similar co-IP experiments were carried out before and at the end of the LatA treatment, using the final supernatant i. Exo- and endocytic traffic was stopped with ice-cold PBS before fixation. Immunofluorescence of cells fixed and analyzed at various time points during LatA experiments Figure 4 B revealed a clear disruption of the actin cytoskeleton in the cells treated with the viddo.
