    Autism Research at the Weizmann Institute of Science

    More and more children are being diagnosed with autism and related conditions, with the Centers for Disease Control (CDC) estimating that about 1 in 88 children has been diagnosed with an autism spectrum disorder (ASD). Fortunately, Weizmann researchers from a number of disciplines are working together to unravel the mysteries of ASDs.

    Immune System Maintains Brain Health

    Prof. Michal Schwartz's groundbreaking research on neuroimmunology changed the way scientists and clinicians view the interaction between the immune system and the brain. <em>The Scientist</em> provides in-depth reporting on what neuroimmunology is, how it works, and why it is so important.

    Unfolding the Mysteries of Proteins

    WeizmannViews Issue No. 46 is about the research of new young scientist Dr. Rina Rosenzweig. She is expert in using super-powerful NMR machines, applying these skills to her studies of misfolded proteins and the clumps they form. These protein “aggregates” are involved in neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and Huntington’s.

    Lighting Up the Mechanisms of Brain Disease

    In Issue No. 47 of Weizmann Views, serendipity leads Dr. Ofer Yizhar to his life’s work: pioneering the remarkable new field of optogenetics. Optogenetics combines optics – the branch of physics concerned with light – and genetics to offer previously unimaginable new ways of studying the brain. Dr. Yizhar's work has particular import for the understanding of autism.

    Turning Down the Brain to Erase Fearful Memories

    Dr. Ofer Yizhar, optogenetics pioneer, has used the tools of that field to successfully shut down a neuronal mechanism that helps form fearful memories in the mouse brain. After the procedure, the mice “forgot” that they had been previously frightened. This research, conducted with Prof. Rony Paz, may someday help extinguish traumatic memories in people.

    Shedding Light on the Secrets of Autism

    The Weizmann Institute’s diverse, creative autism research is exemplified by three recent projects: investigating the immune system-brain development connection, using optogenetics to turn autistic behaviors on and off, and determining the causes of social shyness.

    Could Erasing Traumatic Memories One Day Eradicate PTSD?

    Israel21c reports on research by optogenetics pioneer Dr. Ofer Yizhar. Working with Weizmann colleague Prof. Rony Paz and others, Dr. Yizhar showed that weakening the communication between two parts of the brain reduced fear levels in mice. “This new technique may one day help extinguish traumatic memories in humans – for example, in people with post-traumatic stress disorder, or PTSD.”

    The Brain’s Rejuvenating Cells

    Alzheimer’s disease is a neurodegenerative disease manifested by various neuronal pathological processes and a significant decline in brain function. Aggregates of beta-amyloid protein (“plaques”) accumulate within and between brain cells. Due to both structural changes and the weakening of chemical communication pathways, the junctions of neuronal networks (synapses) are lost. In addition, the cytoskeletal proteins of the axons lose their normal structure, impairing their function and causing massive neuronal death.
