The article discusses similar pathways involving voltage-activated Ca(v)1 channels in two unrelated non-excitable cells: ectoderm cells undergoing neural development and effector Th2 lymphocytes responsible for parasite elimination and allergic diseases. It examines how these channels operate, how they are regulated, and their consequences in terms of gene transcription. The article also considers unresolved questions and potential challenges for the future.
Calcium is a second messenger essential, in all cells, for most cell functions. The spatio-temporal control of changes in intracellular calcium concentration is partly due to the activation of calcium channels. Voltage-operated calcium channels are present in excitable and non-excitable cells. If the mechanism of voltage-operated calcium channels is well known in excitable cells the Ca2+ toolkit used in non-excitable cells to activate the calcium channels is less described. Herein we discuss about very similar pathways involving voltage activated Ca(v)1 channels in two unrelated non-excitable cells; ectoderm cells undergoing neural development and effector Th2 lymphocytes responsible for parasite elimination and also allergic diseases. We will examine the way by which these channels operate and are regulated, as well as the consequences in terms of gene transcription. Finally, we will consider the questions that remain unsolved and how they might be a challenge for the future.
