Organoids are miniaturized 3D tissue structures that have mimic the structure of a human organ, such as the brain. But can an organoid mimic not just the structure, but the function of a brain, and can it grow past beyond the small structure? How much can an organoid develop into something that is useful for studying disorders like autism? On this week’s podcast, we interview Dr. Kevin Kelley, a neuroscientist and psychiatrist from @Stanford University who spent that past decade developing tools to better understand the potential of organoids. He explains how he created the organoids and the systems needed to show that they can develop past a few cells, that they make connections with other brain cells, spread out, connect, and function in a model system like a brain. This new discovery provides more hope for utilizing it as a system for better understanding the autistic brain and for screening lots of treatment candidates for people who need them.

Microglia as a target for new interventions

There is a cell in the brain called the microglia which has been traditionally overlooked as a target for therapies. New research supported by ASF and @FraxAresearch suggests that altering the function of microglia in the brain may help support the development of healthy and functional connections in the brain that may be impaired in autism, making the microglia a prime candidate for research. Drs. Marine Krzisch from @UniversityofLeeds and Dr. Mike Tranfaglia at @FraxAResearch describe the approach and how it can be developed to create specific therapies, that when combined with behavioral interventions, can drastically alter someone’s abilities. Dr. Krzisch is also interviewing families about how the findings will be explained when they are ready, what is important to them and what should research emphasize in the future. Participants will be compensated, just email her: M.Krzisch@leeds.ac.uk

Environmental factors as both causes and interventions?

Environmental exposures, including toxic chemicals, can contribute to the causes of ASD. But how do other environmental factors, like behavioral supports, work in the brain to improve behaviors associated with ASD? For this, you need a broad interpretation of the term “environmental” and an animal model so you can see the mechanism involved. Studies show while environmental factors can contribute, they can also provide modifications in cellular and molecular function which support learning and improved developmental trajectory. Finally, on a different topic, are autistic adults more likely to be involved in a crime compared to other groups? No, they are not, but there are factors which affect the risk of being involved with the criminal justice system, at least in the UK. Read more in the studies below.
