A cornerstone discovery from our lab is that cGAMP, a second messenger, can transmit between cells to broadcast danger and coordinate an immune response. In our new preprint, we show that its role as an immunotransmitter is detrimental for neuroinflammation.

Extracellular cGAMP transmission exacerbates neuroinflammation in aging and multiple sclerosis
Neuroinflammation drives neurodegeneration and cognitive decline in aging, but the signals that spread this inflammation across the CNS remain unclear. Here, we show in mice that advanced age and expe...
