A peptide reduced persistent traumatic memories in mice

A study in mice found that a peptide targeting the memory-related protein CPEB3 reduced the persistence of traumatic memories and anhedonia, a loss of pleasure. The findings are an early genetic preclinical test of a possible approach for PTSD, not evidence of a treatment in people.

Taurine helped steady a protein linked to amyloidosis in lab tests

Laboratory experiments suggest that taurine can regulate transthyretin, a protein involved in thyroid hormone transport and several amyloid diseases. Taurine increased transthyretin’s affinity for thyroid hormone and showed anti-aggregation effects, but its potential as a treatment has not been tested in people.
