Selective detection of neurotransmitters by fluorescence and chemiluminescence imaging*

In recent years, luminescence imaging has been widely employed in neurochemical analysis. It has a number of advantages for the study of neuronal and other biological cells: (1) a particular molecular species or cellular constituent can be selectively visualized in the presence of a large excess of other species in a heterogeneous environment; (2) low concentration detection limits can be achie...

Visualization of flow-induced ATP release and triggering of Ca2+ waves at caveolae in vascular endothelial cells.

Endothelial cells (ECs) release ATP in response to shear stress, a fluid mechanical force generated by flowing blood but, although its release has a crucial role in controlling a variety of vascular functions by activating purinergic receptors, the mechanism of ATP release has never been established. To analyze the dynamics of ATP release, we developed a novel chemiluminescence imaging method b...

Imaging extracellular ATP with a genetically-encoded, ratiometric fluorescent sensor

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...

A novel method using fluorescence microscopy for real-time assessment of ATP release from individual cells.

Many cell types release ATP in response to mechanical or biochemical stimulation. The mechanisms responsible for this release, however, are not well understood and may differ among different cell types. In addition, there are numerous difficulties associated with studying the dynamics of ATP release immediately outside the cell membrane. Here, we report a new method that allows the visualizatio...

Evaluation of Cell-mediated Immune Response in PBMCs of Calves Vaccinated by Capri Pox Vaccines Using ELISA and Real-time RT-PCR

Background: The analysis of antigen-specific cytokine expression has been considered to evaluate the immune responses and vaccines efficacy in recent years. The aim of this study was to compare the cell-mediated immune response characteristics of two Capri pox virus (CaPV) vaccines against lumpy skin disease in cattle. Materials and Methods: Two Capri pox virus vaccines were administered to da...
