Feng and colleagues Robert Desimone, director of the McGovern Institute, and MIT professor Feng Zhang, a co-inventor of the CRISPR technology (pending U.S. Patent and Trademark Office investigation and ruling), are working with Chinese researchers to develop CRISPR - modified macaques — a monkey found in many Old World environments — to model
human schizophrenia and autism.

and cognition, with recent work linking cerebellar dysfunction to such complex diseases as
schizophrenia and autism.
Still, Dudley feels that evolutionary genetic analysis can help identify the most relevant genes
and pathological mechanisms at play in
schizophrenia and possibly other mental illnesses that preferentially affect
humans — that is, neurodevelopmental disorders related to higher cognition

and language bears a relationship with
schizophrenia genetics
and, incidentally,
autism.»
On the negative side, the researchers found that many of the genes whose activity is unique to modern
humans are linked to diseases like Alzheimer's disease,
autism and schizophrenia, suggesting that these recent changes in our brain may underlie some of the psychiatric disorders that are so common in
humans today.
Now researchers at UC San Francisco have taken the first step toward a comprehensive atlas of gene expression in cells across the developing
human brain, making available new insights into how specific cells

and serving as a resource for researchers around the world to study the interplay between these genetic programs
and neurodevelopmental disorders such as
autism, intellectual disability
and schizophrenia.
By modeling early development of the
human cerebral cortex, researchers hope to better study disorders like
autism, epilepsy,

schizophrenia, MS,
autism, Alzheimer's, Parkinson's) using
human induced pluripotent stem cells (iPSCs) derived from donor patients
and differentiated to specific neuronal cell types.
This offers interesting opportunities for interpreting mechanisms of genetic contribution to
human disease such as
schizophrenia,
autism,
and rheumatoid arthritis.
Dendrite development, the Jans have shown, may hold a key to unraveling nerve regeneration, touch perception,
and human mental disorders such as
autism and schizophrenia.

human diseases that affect learning
and memory, including Alzheimer's,
schizophrenia, bipolar disorder,

and ADHD.

autism and schizophrenia.
Integrating
human genetic data with proteomic data showed that Arc - PSD95 complexes are enriched in
schizophrenia, intellectual disability,
