We present protocols for the application of our targeted genetically-encoded calcium indicator (GECI) CatchER+ for monitoring rapid calcium transients in the endoplasmic/sarcoplasmic reticulum (ER/SR) of HEK293 and skeletal muscle C2C12 cells using real-time fluorescence microscopy. A protocol for the in situ Kd measurement and calibration is also discussed.

The protocols outlined herein facilitate the convenient investigation of bacterial ethylene responses by utilizing 2-chloroethylphosphonic acid (CEPA). Ethylene is produced in situ through the decomposition of CEPA in an aqueous bacterial growth medium, circumventing the requirement for pure ethylene gas.

Energy-releasing Steps of Glycolysis

2019
Glycolysis is divided into two phases based on whether energy is utilized or released. While the first phase consumes ATP, the second phase produces energy in the form of ATP and NADH. The energy is released over a sequence of reactions that turns G3P into pyruvate. The energy-releasing phase—steps 6-10 of glycolysis—occurs twice, once for each of the two 3-carbon sugars produced during steps 1-5 of the first phase. The first energy-releasing step—the 6th step of glycolysis —consists of two...
FAQs
After antigen recognition and co-stimulation, intracellular signaling activates transcription of the IL2 gene in activated immune cells, particularly T lymphocytes. The resulting cytokine is secreted and can act on the same cell or nearby cells through IL-2 receptors, linking gene activation to coordinated changes in the adaptive immune response.
The T-cell receptor supplies antigen-recognition input, while co-stimulatory signals help engage the intracellular signaling needed for IL2 transcription. Together, these inputs connect recognition of an antigen with cytokine production. This relationship makes IL-2 release a readout associated with T-cell activation rather than an isolated secretion event.
Binding of IL-2 to receptors on the producing cell or neighboring cells supports proliferation and survival. This local signaling arrangement keeps the response connected to the cells that generated it while also influencing nearby immune cells. Receptor engagement therefore provides the functional link between cytokine release and expansion or persistence of participating lymphocytes.
Measuring IL-2 release can indicate whether immune cells responded to a defined antigen stimulus, because antigen-specific T-cell activation is one context in which the measurement is used. The result can help investigators assess activation patterns rather than simply count immune cells, and it can also support evaluation of immune competence and vaccine responses.
In chronic infection and immunodeficiency research, IL-2 release measurements provide information about the functional state of immune responses. Because IL-2 production follows antigen recognition and co-stimulatory signaling, the measurement can help examine whether adaptive immune activation is occurring effectively. This makes it relevant to studies of persistent infection and impaired immune competence.
IL-2 release is relevant to cytokine-based cancer immunotherapy studies because it reflects signaling associated with activated T lymphocytes and adaptive immune coordination. Measuring this response can help researchers examine immune activation in the context of therapeutic investigations. The same readout also connects cytokine production with the proliferation and survival of responding immune cells.
