Relative increase (↑) or decrease (↓) in P2X and P2Y receptor proteins analyzed by confocal immunofluorascence microscopy in striatum and SN after treatment in rat in vivo with 6-hydroxydopamine (ipsilateral), and in control (not lesioned) brain hemisphere (contralateral).TH= presence in dopaminergic neurons,GABA= presence in GABAergic neurons,GFAP= presence in astrocytes
