CB 2 and toll-like receptors crosstalk in microglia.

Microglia play a major role in certain neuropathological conditions. In a recent paper, Reusch et al. demonstrated how signaling pathways downstream of cannabinoid type 2 (CB) and toll-like receptors (TLRs) converge in these cells. The findings suggest that CB receptors play a permissive role in microglia activation mediated by TLRs.
