Colchicine-Update on mechanisms of action and therapeutic uses.
Singapore, Singapore. In Semin Arthritis Rheum, Dec 2015
Newly described mechanisms include various inhibitory effects on macrophages including the inhibition of the NACHT-LRRPYD-containing protein 3 (NALP3) inflammasome, inhibition of pore formation activated by purinergic receptors P2X7 and P2X2, and stimulation of dendritic cell maturation and antigen presentation.
Purinergic receptors in embryonic and adult neurogenesis.
São Paulo, Brazil. In Neuropharmacology, Nov 2015
While several P2 receptor subtypes were shown to be expressed during in vitro and in vivo neurogenesis, specific functions have been proposed for P2Y1, P2Y2 metabotropic as well as P2X2 ionotropic receptors to promote neurogenesis.
Purinergic Signalling in the Reproductive System.
Cleveland, United States. In Auton Neurosci, Sep 2015
Analysis of functional expression of purinoceptors suggests that P2Y2 receptors are involved in the regulation of luminal fluid secretion in vivo; P2X1 and P2X2 in the regulation of smooth muscle cell contraction of blood vessels and tubular organs; P2X2 in the regulation of sperm cell maturation; P2X3 in activation of sensory nerve fibers involved in reflex activities and pain; P2X4 in the regulation of tight junctional resistance and epithelial transport in female reproductive tract epithelia, and in the regulation of luminal acidification in the epididymis, vas deferens and probably the vagina and ectocervix; P2Y1 and P2Y2 in the regulation of cell proliferation; P2X5 and P2X7A in the regulation of epithelial cell terminal differentiation and apoptosis; and A1 receptors in the regulation of sperm cell capacitation.
Purinergic signalling in the urinary bladder.
Århus, Denmark. In Auton Neurosci, Sep 2015
After release, ATP acts on P2X3 and P2X2/3 receptors on suburothelial sensory nerves to initiate the voiding reflex and to mediate the sensation of bladder filling and urgency.
Sensor Mechanism and Afferent Signal Transduction of the Urinary Bladder: Special Focus on transient receptor potential Ion Channels.
Shenyang, China. In Low Urin Tract Symptoms, 2010
TRPV1, TRPM8, TRPA1, P2X2/3, etc.) have been identified at bladder afferent terminals and have implicated in the generation and modulation of afferent signals, which are elcited by a wide range of bladder stimulations including physiological bladder filling, noxious distension, cold, chemical irritation and inflammation.
Molecular physiology of P2X receptors.
Sheffield, United Kingdom. In Physiol Rev, 2002
Homomeric P2X1, P2X2, P2X3, P2X4, P2X5, and P2X7 channels and heteromeric P2X2/3 and P2X1/5 channels have been most fully characterized following heterologous expression.
Pharmacology of cloned P2X receptors.
Sheffield, United Kingdom. In Annu Rev Pharmacol Toxicol, 1999
Six homomeric (P2X1, P2X2, P2X3, P2X4, P2X5, P2X7) and three heteromeric (P2X2/P2X3, P2X4/P2X6, P2X1/P2X5) P2X receptor channels have been characterized in heterologous expression systems.
