Early Rearing Experience, Hypothalamic-Pituitary-Adrenal (Hpa) Activity, And Serotonin Transporter Genotype: Influences On The Development Of Anxiety In Infant Rhesus Monkeys (Macaca Mulatta), Amanda Dettmer
Open Access Dissertations
A gene x environment interaction exists in the expression of anxiety for both human and nonhuman primates, such that individuals who are carriers of the (s) allele of the serotonin transporter genotype ( 5-HTT LPR) and exposed to early life stress are more at risk for exhibiting anxiety. The hypothalamic-pituitary-adrenal (HPA) axis has also been implicated in anxiety disorders but the relationship between early life/genotype, HPA activity, and anxiety is not well understood. Further, studies linking the HPA axis to anxiety have relied on "point" samples (blood and salivary cortisol) which reflect moments in time rather than long-term activity. The …
