Ion channels are pore-forming membrane proteins that allow ions to pass through the channel pore. Their functions include establishing a resting membrane potential, shaping action potentials and other electrical signals by gating the flow of ions across the cell membrane, controlling the flow of ions across secretory and epithelial cells, and regulating cell volume. Ion channels are present in the membranes of all excitable cells. Ion channels are one of the two classes of ionophoric proteins, the other being ion transporters.

The study of ion channels often involves biophysics, electrophysiology, and pharmacology, while using techniques including voltage clamp, patch clamp, immunohistochemistry, X-ray crystallography, fluoroscopy, and RT-PCR. Their classification as molecules is referred to as channelomics.

Our particular study is on ion channel disturbances of cell voltage and vitality control in neurological, immunological, and chronic diseases.  Voltage-gated ion channels are a class of transmembrane proteins that form ion channels that are activated by changes in the electrical membrane potential near the channel. The membrane potential alters the conformation of the channel proteins, regulating their opening and closing. Cell membranes are generally impermeable to ions, thus they must diffuse through the membrane through transmembrane protein channels. They have a crucial role in excitable cells such as neuronal and muscle tissues, allowing a rapid and co-ordinated depolarization in response to triggering voltage change. Found along the axon and at the synapse, voltage-gated ion channels directionally propagate electrical signals. Voltage-gated ion-channels are usually ion-specific, and channels specific to sodium (Na+), potassium (K+), calcium (Ca2+), and chloride (Cl) ions have been identified. The opening and closing of the channels are triggered by changing ion concentration, and hence charge gradient, between the sides of the cell membrane

The direct targets of extremely low and microwave frequency range electromagnetic fields (EMFs) in producing non-thermal effects have not been clearly established. The voltage-gated properties of these channels provide biophysical evidence of mechanisms for EMF pathophysiologic effects. A substantially supported set of targets, VGCCs, whose stimulation produces non-thermal EMF responses by humans/higher animals with downstream effects involving Ca2+/calmodulin-dependent nitric oxide increases, explain both therapeutic and pathophysiological effects. The key scientific findings that explains the human reaction to EMF radiation on so many levels is Dr Martin Pall's discovery of the mechanism (the cause which has the effect) of the Voltage Gated Calcium channel which, when activated by EMF frequencies has a negative impact on cellular health. Here we look at these findings and the link to other clinical studies and show what we need to do in response to this danger posed by modern life. Remember that Dr Ollie Johansson states that EMF levels are 1 quintillion times higher than they were in the days before mobile. That's a lot of radiofrequency being absorbed and here you can see how it's affecting us.

Channelopathies are diseases caused by disturbed function of ion channel subunits or the proteins that regulate them. These diseases may be either congenital (often resulting from a mutation or mutations in the encoding genes) or acquired[3] (often resulting from autoimmune attack on an ion channel).
