Figure 7. A model of neural-tumour crosstalk mediated by the neuropeptide GAL.

Figure 7

Neurons release GAL following injury or inflammation and activate tumour-expressed GALR2. GALR2 activation leads to NFATC2-mediated transcription and secretion of COX2/PGE2 and GAL, thereby promoting PNI and neuritogenesis, respectively. Targeting GALR2 or GAL blocks PNI by disrupting neural-tumour crosstalk.
