T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Purinergic signaling in hepatic disease [PDF]

Purinergic Signalling, 2019
Extracellular purines (ATP and adenosine) are ubiquitous intercellular messengers. During tissular damage, they function as damage-associated molecular patterns (DAMPs). In this context, purines announce tissue alterations to initiate a reparative response that involve the formation of the inflammasome complex and the recruitment of specialized cells ...

Compensatory Interplay Between Clarin‐1 and Clarin‐2 Deafness‐Associated Proteins Governs Phenotypic Variability in Hearing

Advanced Science, EarlyView.
Functional compensation between clarin‐1 and clarin‐2 in cochlear hair cells. Hearing loss associated with CLRN1 mutations shows striking phenotypic variability; however, the underlying mechanisms remain poorly understood. This study reveals that clarin‐1 and clarin‐2 function cooperatively in cochlear hair cells to sustain mechanoelectrical ...

Purinergic signalling in osteoblasts

Frontiers in Bioscience, 2012
The skeleton is maintained throughout life via the finely tuned actions of osteoblasts and osteoclasts, with disruption in this balance eventually leading to bone disease. The exact mechanisms balancing these actions are not fully known, although several regulatory systems are known to be involved.

A polycystin-type transient receptor potential (Trp) channel that is activated by ATP

Biology Open, 2017
ATP and ADP are ancient extra-cellular signalling molecules that in Dictyostelium amoebae cause rapid, transient increases in cytosolic calcium due to an influx through the plasma membrane.

Polydatin alleviates mitochondrial damage and apoptosis of lung epithelial cells by inhibiting toll‐like receptor 4‐dependent macrophage activation in asthma

Animal Models and Experimental Medicine, EarlyView.
The alleviation of asthma by polydatin is dependent on the blockage of the toll‐like receptor 4 (TLR4)/P2X7R synergy in macrophages. The blockage of the TLR4/P2X7R synergy results in decreased release and secretion of interleukin‐1β (IL‐1β) and IL‐18. In epithelial cells, low IL‐1β and IL‐18 levels inhibit mitochondrial damage and apoptosis.

Purinergic Signaling in Liver Disease [PDF]

Digestive Diseases, 2014
Adenosine triphosphate (ATP) is essential for the myriad of metabolic processes upon which life is based and is known widely as the universal energy currency unit of intracellular biologic reactions. ATP, adenosine diphosphate, adenosine, as well as other purines and pyrimidines also serve as ubiquitous extracellular mediators which function through ...

Endogenous Repair in Vanishing White Matter

Annals of Neurology, EarlyView.
Objective Vanishing white matter is a leukodystrophy with remarkable regional variation in disease severity. The cerebral and cerebellar white matter chronically degenerates, while stress‐induced episodes of rapid neurological deterioration coincide with the appearance of acute focal lesions in the deep gray structures and brainstem.

Highlights in Purinergic Signalling [PDF]

Purinergic Signalling, 2009
It has become increasingly clear that receptors and ion channels in the plasma membrane do not exist and function in isolation, but instead form complexes with other proteins and this can modify their expression and activity. In this study, the authors determined which proteins complex with the P2X2 receptor and characterised the influence of one ...

An emerging role for adenosine and its receptors in bone homeostasis

Frontiers in Endocrinology, 2012
Bone is continually being remodelled and defects in the processes involved lead to bone diseases. Many regulatory factors are known to influence remodelling but other mechanisms, hitherto unknown, may also be involved.
