The voltage-dependent potassium channel Kv1.3 participates in the immune response. Kv1.
View Article and Find Full Text PDFThe voltage-dependent potassium (Kv) channel Kv1.3 regulates leukocyte proliferation, activation, and apoptosis, and altered expression of this channel is linked to autoimmune diseases. Thus, the fine-tuning of Kv1.

Similar to many autoimmune diseases, RA concurs with a long evolution, which eventually results in highly debilitating symptoms. Therapeutic treatments last for long periods during RA.

View Article and Find Full Text PDFPotassium channels are a diverse group of pore-forming transmembrane proteins that selectively facilitate potassium flow through an electrochemical gradient. They participate in the control of the membrane potential and cell excitability in addition to different cell functions such as cell volume regulation, proliferation, cell migration, angiogenesis as well as apoptosis. Because these physiological processes are essential for the correct cell function, K+ channels have been associated with a growing number of diseases including cancer.

View Article and Find Full Text PDFVoltage-dependent K(+) channels (Kv) are involved in a number of physiological processes, including immunomodulation, cell volume regulation, apoptosis as well as differentiation. Some Kv channels participate in the proliferation and migration of normal and tumor cells, contributing to metastasis. Altered expression of Kv1.
View Article and Find Full Text PDFVoltage-dependent K (+) (Kv) channels are tightly regulated during the immune system response. Leukocytes have a limited repertoire of Kv channels, whose physiological role is under intense investigation. A functional Kv channel is an oligomeric complex composed of pore-forming and ancillary subunits.
