Spontaneous Ca2+ signals in the developing mammalian cochlea of live mice under different anaesthetic regimes

open access: yesExperimental Physiology, EarlyView.
Abstract The pre‐hearing mouse cochlea undergoes critical periods of spontaneous Ca2+‐dependent activity that spreads across non‐sensory supporting cells and inner hair cells (IHCs). These signals have been shown to regulate not only the refinement of neural circuits along the auditory pathway towards functional maturity, but also the maturation of the

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

open access: yesExperimental 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 ...

Dual control of vascular tone and remodelling by ATP released from nerves and endothelial cells [PDF]

open access: yes, 2008
Purinergic signalling is important both in short-term control of vascular tone and in longer-term control of cell proliferation, migration and death involved in vascular remodelling.

Long-term (trophic) purinergic signalling: purinoceptors control cell proliferation, differentiation and death [PDF]

open access: yes, 2010
The purinergic signalling system, which uses purines and pyrimidines as chemical transmitters, and purinoceptors as effectors, is deeply rooted in evolution and development and is a pivotal factor in cell communication.

Role of the store-operated Ca𝟐+ channel in ATP-induced Ca𝟐+ signalling in mesenchymal stem cells and regulation of cell functions

open access: yesFrontiers in Bioscience-Landmark, 2021
It is well-known that extracellular ATP acts as an autocrine/paracrine signal to regulate cell functions by inducing intracellular Ca2+ signalling through its cognate receptors, namely, the ligand-gated ion channel P2X receptors that mediate Ca2+ influx ...

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

open access: yesThe 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 ...

Transcriptional and translational differences of microglia from male and female brains [PDF]

open access: yes, 2019
Sex differences in brain structure and function are of substantial scientific interest because of sex-related susceptibility to psychiatric and neurological disorders. Neuroinflammation is a common denominator of many of these diseases and thus microglia

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Protective role of P2Y2 receptor against lung infection induced by pneumonia virus of mice. [PDF]

open access: yesPLoS ONE, 2012
ATP released in the early inflammatory processes acts as a danger signal by binding to purinergic receptors expressed on immune cells. A major contribution of the P2Y(2) receptor of ATP/UTP to dendritic cell function and Th2 lymphocyte recruitment during
