Depletion of the RNA‐Editing Enzyme ADAR1 Invigorates the Antitumor Immunity of NK Cells

open access: yesAdvanced Science, EarlyView.
ADAR1 is upregulated in NK cells from melanoma patients, impairing their function. Its loss enhances NK cell tumor infiltration and cytotoxicity in vitro and in vivo. Mechanistically, ADAR1 deficiency destabilizes CD38 mRNA to reduce its expression, thereby increasing NK cell mobility and killing, which nominates it as a therapeutic target for NK cell ...

Macrophage centripetal migration drives spontaneous healing process after spinal cord injury. [PDF]

open access: yes, 2019
Traumatic spinal cord injury (SCI) brings numerous inflammatory cells, including macrophages, from the circulating blood to lesions, but pathophysiological impact resulting from spatiotemporal dynamics of macrophages is unknown.

Regional differences in store-operated Ca2+ entry in the epithelium of the intact human lens [PDF]

open access: yes, 2009
An elevated level of Ca2+ is an important factor in cataract, yet precisely how Ca2+ enters the lens is unknown. Lens epithelial cells contain a range of G-protein–coupled receptors and receptor tyrosine kinases that induce increases in intracellular Ca2+

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

open access: yesAdvanced 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]

open access: yesPurinergic 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 ...

Purinergic signaling: A gatekeeper of blood-brain barrier permeation

open access: yesFrontiers in Pharmacology, 2023
This review outlined evidence that purinergic signaling is involved in the modulation of blood-brain barrier (BBB) permeability. The functional and structural integrity of the BBB is critical for maintaining the homeostasis of the brain microenvironment.

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

open access: yesAdvanced 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

open access: yesFrontiers 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.

Role of Nucleotide P2 Receptors in the Immune System: Focus on Effector T Cells

open access: yesCells
The emergence of purinergic signaling has given ATP and other extracellular nucleotides a whole new perspective. This concept refers to the fact that extracellular nucleotides released by most cells act as signaling molecules via specific membrane ...

Perturbing purinergic signaling: A pathogen's guidebook to counteracting inflammatory responses

open access: yesBiomedical Journal, 2016
In this issue of the Biomedical Journal, we learn how bacteria and parasites alike counteract inflammatory signaling by manipulating purinergic signaling.
