Prior to a 2019 preprint, “glycoRNAs” weren’t known to exist. Now, the researchers who found them say they’re on lots of cells and may play a role in immune signaling.

Conversations between the immune and central nervous systems are proving to be essential for the healthy social behavior, learning, and memory.

Several routes exist for immune cells to communicate with neurons in the central nervous system, though T cells rarely come in direct contact with neural tissue.

Scientists demonstrate that just the right amount of inflammation after an injury to a mouse’s olfactory epithelium is key for regenerating cells important for smell.
