26004513-12	2015	P2Y2, P2Y4 and P2Y6 receptors expressed on the vascular smooth muscle are coupled to vasocontraction, and may have a role in pathophysiological conditions, when purines are released from damaged cells, or when there is damage to the protective barrier that is the endothelium.	Purines	161-168	pyrimidinergic receptor P2Y4	Homo sapiens	6-10	
28066160-8	2016	The "purinergic hypothesis" is that MS releases purines to act in an autocrine/paracrine manner to activate excitatory (P2Y1, P2Y4, P2Y6, and A2A/A2B) or inhibitory (P2Y12, A1, and A3) receptors to regulate 5-HT release.	Purines	48-55	pyrimidinergic receptor P2Y4	Homo sapiens	126-130
