Adenosine—A Regulator of Human Testicular Peritubular Cells

Andrology, EarlyView.
ABSTRACT Background Extracellular purines, in particular ATP and adenosine, are regulators of physiological and pathophysiological processes throughout the human body. Roles in the human testis are emerging and include actions on peritubular cells, which form the wall of seminiferous tubules.

Pathophysiology and emerging treatments for dermographic, cholinergic and cold urticaria

Journal of the European Academy of Dermatology and Venereology, EarlyView.
This review illustrates key proposed mast cell‐mediated activation pathways in dermographic, cholinergic and cold urticaria, highlighting IgE‐dependent and ‐independent mechanisms. These pathways are increasingly targeted by emerging drugs, aiming to interrupt mast cell activation and mediator release, offering more precise, mechanism‐based treatment ...

Regulated to respond: dual localization and dynamic control of AVP1 in plant carbon partitioning

Frontiers in Plant Science
Arabidopsis Vacuolar Pyrophosphatase 1 (AVP1), a conserved type I proton-pumping pyrophosphatase (H+-PPase), was characterized as tonoplast localized with a role in acidifying the lumen and removing cytosolic pyrophosphate (PPi), a byproduct of ...

Chemical agents to control biofilm formation in step 1 of care—Toothpastes and mouthwashes/concepts and challenges

Periodontology 2000, EarlyView.
Abstract Maintaining optimal oral hygiene is important for overall oral care, ensuring the well‐being of teeth and their surrounding tissues. In addition, it promotes fresh breath and a pleasing smile. A key element of oral self‐care is the daily use of toothpaste during regular brushing.

Understanding exosomes in regenerative dentistry

Periodontology 2000, EarlyView.
Abstract Background Regenerative dentistry is shifting from cell‐based strategies to cell‐free biologics capable of orchestrating intricate tissue repair. Exosomes, nanosized extracellular vesicles carrying bioactive molecular payloads, have emerged as central modulators of intercellular communication.

Vacuolar proton pyrophosphatase activity and pyrophosphate (PPi) in Toxoplasma gondii as possible chemotherapeutic targets

, 2000
The addition of PPi promoted the acidification of a subcellular compartment in cell homogenates of Toxoplasma gondii tachyzoites, implying the presence of a proton-translocating pyrophosphatase.
