I decided when I was about my daughter’s age, that food rules all. It’s the great connector of people. Through our experiences, hearing the stories of those since passed, creating magic in the kitchen, and sharing that around the table is how we are able to learn, grow, heal, and connect as a species.

This month’s Autism 200 series class is Autism 202: Best Practices in ASD Treatment: Applied Behavior Analysis Update
Instructors: Mendy Minjarez, PhD, and Elizabeth Hatzenbuhler, MS, BCBA
Interventions grounded in applied behavior analysis (ABA) have demonstrated effectiveness across a variety of individuals and behaviors especially within the treatment of autism. Decades of research support that ABA is an effective scientific methodology with an emphasis on teaching skills and reducing challenging behaviors. As ABA can be implemented in many different ways and the field has evolved over the last few decades, there are many types of treatment strategies supported by a large body of knowledge. As such, this can be confusing for parents, autistic individuals and other consumers outside of the field to navigate. This talk will provide an overview of the defining features of the science of ABA, provide an overview of some examples of how it can be applied and discuss quality indicators that can be used to evaluate ABA programs. It will also highlight some of the misconceptions and sources of confusion about ABA, including the origins of these issues as well as the response from the ABA field.
This class will be held Thursday, February 21, 2019, at Seattle Children’s Hospital in Wright Auditorium from 7:00 to 8:30 p.m.
Please join us in person or watch on Facebook live. For more information see the Autism 200 Series webpage.
In this month’s Science with Sara blog entry, I’ve asked two researchers from the University of Washington & Seattle Children’s Research Institute — whose work falls under the broad area of the Biology Underlying ASD – to highlight an important or informative review or summary paper from their field.
Dr. Stephen Smith PhD is an Assistant Professor at the UW and Seattle Children’s Research Institute. His work focuses on how proteins located at the junctions between brain cells (called synapses) work or, in the case of neurodevelopmental disorders, why they might malfunction. Dr. Smith uses multiple animal models of ASD in order to understand how different genetic variants impact synapse function, and in turn, how this changes how a person learns and remembers.
Dr. Smith’s Pick:
• Sestan, N., & State, M. W. (2018). Lost in Translation: Traversing the Complex Path from Genomics to Therapeutics in Autism Spectrum Disorder. Neuron, 100(2), 406-423. https://www.sciencedirect.com/science/article/pii/S0896627318309036
“This beast of a review paper is co-authored by Dr. Matthew State, who has been at the forefront of gene discovery in Autism for many years. I hesitate to recommend this paper for a non-specialist audience because it is so dense, but its depth and quality make it worth the effort. While it’s a bit heavy on the details of the genetics (Dr. State is a geneticist, after all), the main takeaway is that, after many years of gene discovery, we are beginning to understand the central pathways that are disrupted in autism- neuronal signaling, dynamic control of DNA translation, and how those processes play central roles in development. State and his co-author Dr. Nenad Sestan then discuss future efforts to understand how mutated genes lead to atypical behavior. Although this is clearly a difficult path, they outline a plausible route that many research groups, including mine, will be taking in the years ahead.“

Dr. Smita Yadav PhD is an Assistant Professor in Pharmacology at the UW. Her work focuses on neuronal networks (networks of brain cells) and specifically on how molecules regulate communication between brain cells. One focus of Dr. Yadav’s research is in the 16p11.2 genetic location – there are 29 genes that are in this region of our DNA, and structural changes to this area of our DNA are associated with both ASD and schizophrenia.
Dr. Yadav’s pick:
• Quesnel-Vallières, M., Weatheritt, R. J., Cordes, S. P., & Blencowe, B. J. (2018). Autism spectrum disorder: insights into convergent mechanisms from transcriptomics. Nature Reviews Genetics, 1. https://www.nature.com/articles/s41576-018-0066-2
“The first one is a review about understanding the ~75% non-syndromic, idiopathic cases of autism. The authors argue that a common pathway is emerging from transcriptome analyses that implicates RNA processing in ASD. The evidence includes: (1) cortical patterning of gene expression is lost in autism; (2) mRNA, lncRNA, miRNA and other non-coding RNA programmes are disrupted in ASD; (3) subsets of mRNAs regulating neuronal processes are consistently downregulated in individuals with ASD; and (4) RNA splicing regulatory programmes disrupted in ASD are responsive to neuronal activity and, conversely, affect neuronal activity.”

“The second paper is a review on using 3D brain organoids to model neuropsychiatric diseases. While this review is not specific to autism, in my view, this space is where a lot of the research on the biological basis of autism will be in the future. The different kinds of organoids and the questions that we can now ask are quite amazing. Some caveats of this technology remain.”
