New work from the lab on how sickness reduces appetite. Turns out, it’s complicated :)

We focused on a single inflammatory cytokine, IL-1b, and even that reduces appetite via multiple mechanism.

Thanks to Nik Hayes for leading and sticking with this project and to everyone else who contributed!

Astrocyte-microglia crosstalk through Hevin and Toll-like receptor signaling controls developmental thalamocortical synapse refinement Microglia are key drivers of synapse refinement during development. Ramirez et al. show that astrocytes instruct this process through the secreted synaptogenic protein Hevin/Sparcl1. The proteolytical...
