Identifying Molecular Targets for PTSD Treatment Using Single Prolonged Stress

Abstract

Our statement of work proposed that in our first two years of funding, we would examine whether SPS disrupts extinction retention by disrupting consolidation and/or retrieval of extinction memory, and/or enhancing fear memory reconsolidation or by disrupting contextual modulation of extinction retrieval. Data collection and analysis for all of these experiments, detailed in Specific Aim 1. We proposed that work on Specific Aim 2, in which we examine if SPS enhancement in brain GR and beta-AR expression alters glutamatergic and GABAergic function in neural circuits that mediate SPS-induced deficits in extinction retention, would also have been started during the first two years and we have completed the behavior part and tissue collection for 5/8 experiments described in this aim. Molecular assays are planned for the coming year. In addition to completing the above, we have begun, completed and published some of the work proposed in Specific Aims 3 and 4 that was timetabled for later in the funding period. In this report we detail findings from several of these experiments. We feel confident that we have exceeded the goals set out in our statement of work due to the large numbers of experiments for which data collection is complete, and the progress made on Specific Aims 3 and 4 ahead of schedule.
