Opfer des Krieges: Beiträge des cholinergen Systems zur Entwicklung von PTSD bei Kindern und Jugendlichen in Palästina und Israel
Zusammenfassung der Projektergebnisse
In summary, the extension of the DFG grant allowed us to achieve several important steps in the context of traumatic stress research, but also in the improved collaboration and interaction between Palestinian, Israeli, and German research groups. With respect to endocrine indicators for long-term stress, the data confirmed and extended current influential models of hormonal secretion over different phases of traumatic stress. The imaging data revealed novel findings regarding the functional relationship between microstructural integrity of specific CC portions and altered cognitive, and specifically memory, performance in PTSD. The preliminary findings from the genetic data demonstrate the contextdependent contribution of variations in genomic sequences to long-term stress reactions, opening new venues for understanding the impact of relevant non-coding RNA candidates on PTSD. Integrating structural, molecular and cell and animal approaches can open new venues for identifying the complex regulators governing cholinergic functioning in PTSD. In general, the results may have consequences for diagnostic tools and future studies aimed at identifying individuals at risk for PTSD, and in turn, develop individual-based treatments that assist in preventing the chronicity of this disorder. More than the scientific contribution of the grant, however, the social and societal implications cannot be stressed enough. The fact that German, Israeli, and Palestinian scientists worked together, visited each other’s countries and exchanged idea with respect to scientific and mundane contexts, and that fruitful collaborations and networks which will exist for the future years to come could be established, in our opinion, may be viewed as the most significant and sustainable result of this scientific collaboration.
