Description:
Glycerophospholipids, the structural components of cell membranes, have not been considered to be spatial cues for intercellular signaling because of their ubiquitous distribution. We identified lyso-phosphatidyl-beta-D-glucoside (LysoPtdGlc), a hydrophilic glycerophospholipid, and demonstrated its role in modality-specific repulsive guidance of spinal cord sensory axons. LysoPtdGlc is locally synthesized and released by radial glia in a patterned spatial distribution to regulate the targeting of nociceptive but not proprioceptive central axon projections. Library screening identified the G protein-coupled receptor GPR55 as a high-affinity receptor for LysoPtdGlc, and GPR55 deletion or LysoPtdGlc loss of function in vivo caused the misallocation of nociceptive axons into proprioceptive zones. These findings show that LysoPtdGlc/GPR55 is a lipid-based signaling system in glia-neuron communication for neural development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guy, Adam T -- Nagatsuka, Yasuko -- Ooashi, Noriko -- Inoue, Mariko -- Nakata, Asuka -- Greimel, Peter -- Inoue, Asuka -- Nabetani, Takuji -- Murayama, Akiho -- Ohta, Kunihiro -- Ito, Yukishige -- Aoki, Junken -- Hirabayashi, Yoshio -- Kamiguchi, Hiroyuki -- New York, N.Y. -- Science. 2015 Aug 28;349(6251):974-7. doi: 10.1126/science.aab3516.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉RIKEN Brain Science Institute, 2-1 Hirosawa, Wako, Saitama 351-0198, Japan. ; RIKEN Brain Science Institute, 2-1 Hirosawa, Wako, Saitama 351-0198, Japan.
