Optimization of photobiomodulation therapy for spinal cord injury: A review

Photochemistry and Photobiology, EarlyView.
Photobiomodulation (PBM) therapy in the red and near‐infrared range can significantly modulate the secondary injury response and promote the reparative and regenerative potential of neural tissue after spinal cord injury (SCI). At present, due to the nature of delivery methods, the most effective dose and irradiance at the injury site to optimize ...

Ligand-Independent Spontaneous Activation of Purinergic P2Y₆ Receptor Under Cell Culture Soft Substrate

Cells
G protein-coupled receptors (GPCRs) exist in the conformational equilibrium between inactive state and active state, where the proportion of active state in the absence of a ligand determines the basal activity of GPCRs.

Functional expression and intracellular signaling of UTP-sensitive P2Y receptors in theca-interstitial cells

Reproductive Biology and Endocrinology, 2010
Background Purinergic receptors are expressed in the ovary of different species; their physiological roles remain to be elucidated. UTP-sensitive P2Y receptor activity may regulate cell proliferation.

Role of S1P‐ and Rho‐kinase signalling in age‐related myogenic tone deficiency in murine resistance arteries

Experimental Physiology, EarlyView.
Abstract Ageing is a risk factor for cardiovascular and neurodegenerative diseases. The myogenic response in resistance arteries is responsible for basal (myogenic) tone and blood flow autoregulation. G‐protein‐coupled receptors and G12/RhoA/Rho kinase are implicated in myogenic tone (MT), and we aimed to clarify their role in pressure sensing and ...

Expression of P2 receptors in human B cells and Epstein-Barr virus-transformed lymphoblastoid cell lines

BMC Immunology, 2006
Background Epstein-Barr virus (EBV) infection immortalizes primary B cells in vitro and generates lymphoblastoid cell lines (LCLs), which are used for several purposes in immunological and genetic studies. Purinergic receptors, consisting of P2X and P2Y,

Purinoreceptors and ectonucleotidases control ATP-induced calcium waveforms and calcium-dependent responses in microglia: Roles of P2 receptors and CD39 in ATP-stimulated microglia

Frontiers in Physiology, 2023
Adenosine triphosphate (ATP) and its metabolites drive microglia migration and cytokine production by activating P2X- and P2Y- class purinergic receptors.

The role of dinucleoside polyphosphates on the ocular surface and other eye structures [PDF]

, 2016
Dinucleoside polyphosphates comprises a group of dinucleotides formed by two nucleosides linked by a variable number of phosphates, abbreviated NpnN (where n represents the number of phosphates). These compounds are naturally occurring substances present

Glial cells in the heart: Implications for their roles in health and disease

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of cardiac autonomic ganglia within epicardial fat pads (posterior heart surface shown), containing vagal postganglionic neuron cell bodies, associated fibres, and glia. These ganglia receive cholinergic input from vagal preganglionic neurons and adrenergic input from sympathetic postganglionic neurons ...

The E-NTPDase Family of Ectonucleotidases: Structure Function Relationships and Pathophysiological Significance [PDF]

, 2011
Ectonucleotidases are ectoenzymes that hydrolyze extracellular nucleotides to the respective nucleosides. Within the past decade, ectonucleotidases belonging to several enzyme families have been discovered, cloned and characterized.
