Parkinson's disease (PD) is characterised by the degeneration of the dopaminergic nigrostriatal pathway. Cell therapy using intranigral transplantation of foetal ventral mesencephalon (VM) cells in a mouse model of PD results in anatomical and functional reconstruction of the pathway. This suggests a role for axon guidance molecules (GMs) in reconnecting transplanted cells to their striatal target. To test this hypothesis, we studied the expression of axon GMs in the intact adult brain, on cells used for transplantation and in a mouse model of PD after cell therapy. In the intact brain, we showed that GMs as semaphorin7A (Sema7A) and Sema3A and their corresponding receptors, plexinC1 and neuropilin1, retain an expression at the protein level, therefore showing a possible role for these guidance cues in the adult brain. Moreover, using microarray, we studied GM receptor expression profiles in two types of cells used for transplantation and exhibiting different functional ameliorations. Robo2, neuropilin1, neuropilin2, EphA5 and DCC receptors showed differential expression between the two cellular populations, indicating their possible contribution to the different functional outcomes observed. In the lesioned mouse brain, we observed, using RT-qPCR, variations of mRNA expression of these axon GMs after intranigral transplantation of foetal VM derived cells, thus suggesting the implication of Sema3A, Sema3F, and Sema7A in the reconstruction of the pathway. Overall, this work highlights particular importance of semaphorins in the nigrostriatal pathway reconstruction. Integrating these cues in transplantation procedures can possibly optimize cell therapy for PD patients.
