"The Max Planck Society is Germany's most successful research organization. Since its establishment in 1948, no fewer than 18 Nobel laureates have emerged from the ranks of its scientists, putting it on a par with the best and most prestigious research institutions worldwide. The more than 15,000 publications each year in internationally renowned scientific journals are proof of the outstanding research work conducted at Max Planck Institutes – and many of those articles are among the most-cited publications in the relevant field."

Research at the Max Planck Institute of Experimental Medicine focuses on the genetic, molecular, and cellular processes that control the formation and integrity of the nervous system and its malfunction in neurodevelopmental and neurodegenerative diseases. A particular emphasis is on neural development and function, signaling between nerve cells and neuroplasticity, and the complex functional and metabolic interplay between glial cells and neurons in the brain. Scientists at the institute study the basic biology of these processes - from the molecular and cellular to the systems level, and from mouse to man - and their perturbations in model diseases such as stroke, multiple sclerosis, leukodystrophies, schizophrenia, or autism.

Autism spectrum disorders are largely of genetic origin, and 5-10% of cases are currently known to be caused by a single gene mutation. Understanding the consequences of these mutations in detail can open the way for medical treatment. The study presented in this video focused on how a frequent mutation seen in patients with autism spectrum disorders causes the brain dysfunction that leads to the behavioral symptoms. Based on mice with the same genetic lesion that is known to cause autism spectrum disorder in human patients, mutant brains and nerve cells and the behavior of mutant mice were examined. The mice showed clear signs of autism related behavioral defects, and further analyses provided insights into the changes in brain function that are caused by the gene mutation, as NILS BROSE explains in this video. The corresponding data show that synapses of nerve cells that use the neurotransmitter GABA are particularly affected by the mutation. If these results can be confirmed to reflect the situation in the human body, there would be a chance to interfere with medication targeting GABAergic synapses.
