Core Tip

Core tip: We propose that susceptibility to post-traumatic stress disorder (PTSD) may be determined, in part, by aberrant microtubule-associated protein tau expression in neurons of critical brain structures. We review several lines of evidence to support this novel hypothesis. In addition, we review types of PTSD, namely non-classical PTSD, induced by various medical conditions and address this issue of why non-classical PTSD can be reliably elicited. To verify our hypothesis, we propose to use animal models of PTSD combined with laser-assisted/capture microdissection and microarray analysis to examine gene expression changes in selected cellular elements in response to the occurrence of PTSD.
