The Section on Neuroadaptation and Protein Metabolism is an integral part of the Neuroscience Research community at the National Institutes of Health. We are located on the NIH campus in Bethesda, Maryland in the Division of Intramural Research of the National Institute of Mental Health.
The aim of our research is to understand the role of protein metabolism in adaptive responses of the nervous system. Our work is built on the idea that long-term changes in the environment such as occur during development and aging, in response to synaptic activity and hormones, and as a result of disease or injury produce regional adjustments in protein metabolism that underlie growth, remodeling, degeneration, regeneration, and involution.

To study protein metabolism we develop, apply, and refine imaging methods that can be used to quantitatively measure these changes in vivo in all structures of the nervous system in animals and in man.
We are currently investigating fragile X syndrome (FXS), the most common inherited cause of mental impairment and the most common known cause of autism. |

Our results in a mouse model of FXS indicate that there are defects in brain protein synthesis that may underlie disease symptoms.
Presently, we are testing for these effects on brain protein synthesis in clinical studies of subjects with FXS. These studies together with our complementary studies of behavior and cerebral energy metabolism are providing us with an integrated view of affected systems and circuits in FXS, and may provide insight into other neurodevelopmental disorders. Understanding causal factors is fundamental to developing strategies for therapeutic intervention.
