“Researchers…show that inhibiting a kinase (kinases are enzymes that change proteins) called Cdk5 facilitates the extinction of fear learned in a particular context. Conversely, the learned fear persisted when the kinase’s activity was increased in the hippocampus, the brain’s center for storing memories.

Cdk5, paired with the protein p35, helps new brain cells, or neurons, form and migrate to their correct positions during early brain development.

“Remarkably, inhibiting Cdk5 facilitated extinction of learned fear in mice. This data points to a promising therapeutic avenue to treat emotional disorders and raises hope for patients suffering from post-traumatic stress disorder or phobia,”…” Full Slice
