Adenosine (P1) receptor signalling

Drug Development Research, 1996
The coupling of the four defined types of adenosine receptors to G proteins and the consequent activation of effector pathways is briefly summarized. It is pointed out that the G proteins are able to influence many types of cellular effector systems, and, in particular, that the a and the β,γ-subunits may activate different signalling pathways that may

P1- and P2-purine receptors in brain circulation

European Journal of Pharmacology, 1987
As there is increasing evidence that purines are involved in cerebral vasodilatation, purine receptors were characterized pharmacologically in pial arteries from rabbit, cat and man, and compared with purine receptors in various non-cerebral vascular beds.

P1 Receptors in the Cardiovascular System

2001
The presence of adenosine receptors on cardiovascular tissues has previously been established on the basis of functional responses to adenosine and adenosine analogs. Specific functions attributed to each of the four adenosine receptor subtypes (A1, A2A, A2B, and A3) are discussed in detail below following a summary of the direct evidence for adenosine

Molecular architecture of mouse activating NKR-P1 receptors

Journal of Structural Biology, 2011
Receptors belonging to NKR-P1 family and their specific Clr ligands form an alternative missing self recognition system critical in immunity against tumors and viruses, elimination of tumor cells subjected to genotoxic stress, activation of T cell dependent immune response, and hypertension.

P1 Receptors in the Respiratory System

2001
In this chapter the role of adenosine receptors in the modulation respiratory system is reviewed. The chapter is divided into sections based on the effects of adenosine receptors on the different aspects of pulmonary physiology. The potential role of PI purinergic receptors in the regulation of epithelial and endothelial function, ventilatory drive ...
