Preclinical animal and cellular models are notoriously bad at predicting drug candidate toxicity in humans. Animal biology is often fundamentally different on this front than in humans, while cells in the lab can't be counted on routinely to replicate the bodily response.
A subtype of schizophrenia is related to abnormally high brain levels of hydrogen sulfide (H2S), which has important implications for the development of new treatments, according to a study by researchers at the RIKEN Center for Brain Science (CBS) in Japan.
A Chinese study has identified small-molecule compounds that can selectively reduce levels of the mutant Huntingtin (HTT) protein involved in the pathogenesis of Huntington's disease (HD), and possibly other neurodegenerative diseases involving mutant protein accumulation.
