Puberty Triggers Brain Rewiring in Genetic Condition Tied to Autism

Categories Brain & Behavior
UTSW researchers used a technique called optogenetic circuit mapping in which they inserted a gene into targeted neurons, allowing their activity to be controlled by light. By stimulating neurons that deliver inputs to the HVC, an area of the avian brain involved in birdsongs, then measuring the electrical activity of outputting neurons, the team could see which neurons communicated with one another.

Researchers at WashU Medicine identified a direct connection between cancer-related inflammation and the loss of motivation characteristic of advanced cancer. In a mouse study they describe a brain pathway that starts with neurons (labeled in green, above) that sense inflammation signals, and the researchers were able to treat the loss of motivation by blocking this pathway.

CD8 T cell priming occurs in two phases. In the activation phase (day 1), naïve T cells engage with dendritic cells (DC) for 24 hours, then detach, proliferate, and move deeper into the lymph node. In the selection phase (days 2-3), activated T cells regain sensitivity, re-engage with antigen-presenting cells, and receive IL-2 support from CD4 T cells. Regulatory T cells limit IL-2 availability, driving the expansion and differentiation of high-affinity CD8 T cells into effector cells.
