Outline of Final Research Achievements

Propofol increased RhoA activation, collapsed growth cones, and impaired retrograde axonal transport ofquantum dot-labelled brain-derived neurotrophic factor, all of which were prevented with TAT-C3. Adult mice previously treated with propofol had decreased numbers of total hippocampal synapses and presynaptic vesicles, reduced hippocampal dendritic arborisation, and infrapyramidal mossy fibres. These mice also exhibited decreased hippocampaldependent contextual fear memory recall. All anatomical and behavioural changes were prevented with TAT-C3 pretreatment.
