Adenosine triphosphate (ATP) is known as an energy source and generated by mitochondria which the powerhouse of cell. The ATP supplies through disassociation phosphate group cellular enzymes. extracellular in environment acts a signaling molecule can act anti-inflammatory molecule, promote cancer progression, also pro-inflammatory molecule. degradation major disadvantage ectonucleotidases that ...
ATP is a vital molecule used by living organisms as a universal source of energy required to drive the cogwheels of intracellular biochemical reactions necessary for growth and development. Animal cells release ATP to the extracellular milieu, where it functions as the primary signaling cue at the epicenter of a diverse range of physiological processes. Although recent findings revealed that in...
A survey of the extracellular ATP levels of 86 heterotrophic bacteria showed that gram-negative bacteria of the genera Sulfitobacter, Staleya, and Marinobacter secreted elevated amounts of extracellular ATP, ranging from 6.0 to 9.8 pM ATP/colony forming unit (cfu), and that gram-positive bacteria of the genera Kocuria and Planococcus secreted up to 4.1 pM ATP/cfu. Variations in the levels of ex...
Extracellular purinergic products, particularly ATP, have recently been implicated to regulate immune cell functions and contribute to aberrant inflammatory responses of immune diseases. However, regulation of immune responses of colitis by extracellular ATP and its main receptor, P2 × 7, remains to be elucidated. In the study, we induced murine colitis by feeding mice with 4% dextran sulfate s...
Our previous work has demonstrated that islet depolarization with KCl opens connexin36 hemichannels in β-cells of mouse pancreatic islets allowing the exchange of small metabolites with the extracellular medium. In this study, the opening of these hemichannels has been further characterized in rat islets and INS-1 cells. Taking advantage of hemicannels'opening, the uptake of extracellular ATP a...
Extracellular adenosine triphosphate (ATP) is a key purinergic signal that mediates cell-to-cell communication both within and between organ systems. We address the need for a robust and minimally invasive approach to measuring extracellular ATP by re-engineering the ATeam ATP sensor to be expressed on the cell surface. Using this approach, we image real-time changes in extracellular ATP levels...
Cooling method was proposed to maintain the sperm quality for several days. Nevertheless, during this procedure, sperm is encountered to “cold shock”, and its quality decreases time-dependently. This study was designed to improve the in vitro sperm preservation methods. Thirty normal semen samples were examined in Shiraz, Iran, 2017. Fifteen samples were incubated at 22-27 °C and 15 samples wer...
Most cells release ATP to the extracellular milieu. Extracellular ATP plays important signaling roles by activating a score of broadly distributed cell surface purinergic receptors (purinoceptors). Biological responses regulated by purinergic receptors include neurotransmission, smooth muscle relaxation and contraction, epithelial cell ion transport, inflammation, platelet activation, immune re...
