An exacerbated immune response is one of the main causes of influenza-induced lung damage during infection. The molecular mechanisms regulating the fate of the initial immune response to infection, either as a protective response or as detrimental ...

Purinergic signaling in schistosomal infection
Human schistosomiasis is a chronic inflammatory disease caused by blood fluke worms belonging to the genus Schistosoma. Health metrics indicate that the disease is related to an elevated number of years lost-to-disability and years lost-to-life ...

ER localized bestrophin1 activates Ca2+ dependent ion channels TMEM16A and SK4 [PDF]
Bestrophins form Ca2+ activated Cl- channels and regulate intercellular Ca2+ signaling1. We demonstrate that bestrophin 1 is localized in the endoplasmic reticulum (ER), where it physically interacts with stromal interacting molecule 1 (Stim1), the ER ...

Macrophages exhibit diverse phenotypes and functions; they are also a major cell type infiltrating chronically rejected allografts. The exact phenotypes and roles of macrophages in chronic graft loss remain poorly defined. In the present study, we used a

Microglia modulate blood flow, neurovascular coupling, and hypoperfusion via purinergic actions
Microglia modulate cerebral blood flow (CBF) through complex purinergic actions, which are mediated by dynamic, P2Y12 receptor-driven interactions with the vasculature. Microglial actions are partially independent of nitric oxide.

Purinergic receptors in airway epithelia [PDF]
Nucleotides and nucleosides within the airway surface liquid regulate mucociliary clearance (MCC) activities, the primary innate defense mechanism that removes foreign particles and pathogens from airway surfaces. Nucleotide and nucleoside actions in the airways are mediated mainly by two purinergic receptor subtypes, the Gq-coupled ATP/UTP-sensing ...

Simultaneous quantification of 12 different nucleotides and nucleosides released from renal epithelium and in human urine samples using ion-pair reversed-phase HPLC [PDF]
Nucleotides and nucleosides are not only involved in cellular metabolism but also act extracellularly via P1 and P2 receptors, to elicit a wide variety of physiological and pathophysiological responses through paracrine and autocrine signalling pathways.

Idiopathic pulmonary fibrosis (IPF) is a devastating disease with few available treatment options. Recently, the involvement of purinergic receptor subtypes in the pathogenesis of different lung diseases has been demonstrated.

Purine and purinergic receptors [PDF]
Adenosine 5′-triphosphate acts as an extracellular signalling molecule (purinergic signalling), as well as an intracellular energy source. Adenosine 5′-triphosphate receptors have been cloned and characterised. P1 receptors are selective for adenosine, a breakdown product of adenosine 5′-triphosphate after degradation by ectonucleotidases.

The mechanism of secondary cognitive impairment following AKI. When renal ischemic injury progresses to fibrosis, renal fibroblasts and damaged tubular cells secrete MDK, which circulates through the bloodstream, crosses the damaged BBB, and accumulates in the hippocampus tissue (an area crucial for learning and memory).
