Animal models of human disorders are often used for testing therapeutic drugs, but in some cases, the results fail to translate into clinically relevant treatments, a growing concern for biomedical research. Scientists are working hard to identify and address the causes underlying such clinical failures. Among them are Ehud Fonio (Weizmann Institute of Science, Rehovot,ContinueContinue reading “Missteps in animal behavioral models of anxiety”

Cannabinoids prevent post-traumatic stress
Previous work by Eti Ganon-Elazar and Irit Akirav (University of Haifa, Israel) suggested that cannabinoids might have a role in treating stress and anxiety disorders. Recently, the two researchers specifically examined post-traumatic stress disorder (PTSD), an anxiety disorder whose hallmark symptoms include an exaggerated acoustic startle reflex and enhanced negative feedback on the hypothalamic-pituitary-adrenal axis.ContinueContinue reading “Cannabinoids prevent post-traumatic stress”
Gut bacteria ease anxiety
Benign bacteria such as Lactobacillus rhamnosa, a probiotic found in yogurt, can have mood-altering effects in healthy mice, according to a new study directed by John Bienenstock (McMaster University, Hamilton, Ontario, Canada) and John F. Cryan (University College Cork, Ireland). There is much evidence that commensal gut bacteria influence physiology in various ways but, untilContinueContinue reading “Gut bacteria ease anxiety”
