Genetic confounding plus organoids

You heard it in the news this week, and we discuss it on this week’s ASF podcast. Can you make little brains in a dish then make them better by providing them a real structured live neural environment? Can these organoids integrate with a live brain and be functional in vivo? The answers are: yes! Learn more from a new study published this week. Also, what the h**l is genetic confounding and how can it address many of the controversies of genetic vs. the environment? Sometimes genes that predispose to a disorder also predispose to environmental factors leading to that disorder. There is always room for both. Here are the links I promised:

Is Autism Inflammation Nation?

Several studies have linked the immune system to autism, but how are they connected? Two new studies this week illustrate differences in immune function in those with a diagnosis compared to those without, and also find differences in the blood of of pregnant mothers who go on to have an autistic child. Women who go on to have autistic girls show higher levels and more inflammatory markers than mothers who go on to have boys, the finding of elevated IL1 is now a finding that has been replicated across countries. However, it’s too early to tell if this information can be used to help with a diagnosis and it’s probably not specific to autism. But the message is the same as it was before: getting sick during pregnancy is not great. Get vaccinated! Stay away from sick people and wash your hands.
