Genetic markers linked to the regulation of the immune system and which have been associated with a post – traumatic stress disorder (PTSD), have been identified. The identification was done on blood samples from 124 male US marines before they were deployed and three months later on returning from deployment.
This kind of a disclosure would call for identification of a new diagnostic technique as well as medication. It would also bring along the need to foresee the people that are more exposed to the risks associated with this disorder.
An evaluation has revealed that 6.8% of Americans will eventually have PTSD later in their lives. In them, you will notice troubled memories, extreme tension, and sleeping tension and to the very extreme you may notice contemplations of self – destruction. Senior author Michael S. Breen, from the University of Southampton gets into elaborating this by relating US Marines who had developed PTSD to those who did not.
From his comparison, the differences in genes could be measured while taking into consideration the dynamism in the relationship between them which would in return explain their connectivity. Owing to the fact that PTSD has always been thought to be an intricate disorder, the measurement of the dynamic relationships would bring along some sort of understanding the PTSD pathology.
Interestingly, before and after PSTD development, the researchers identified two groups of genes; innate immune system and interferon signaling. This raised a lot of questions into wanting to know what really triggered interferon signaling before PSTD.
The principal investigator, Dr. Dewleen G. Baker said that this would be as a result of various factors that included increased anticipatory stress before the marines were deployed. He also explained that it would be as a result of tough scenarios of individuals with higher loads.
However, the scientists still fell that there is need to have a comparative methodology into looking at the distinguished hereditary markers of PTSD.
