NFAT Activator

Ionomycin is a membrane permeable calcium ionophore produced by the bacterium Streptomyces conglobatus. This ionophore facilitates the transfer of calcium ions (Ca2+) into and out of cells [1]. Ionomycin can be used to increase intracellular calcium levels triggering cell death through apoptosis and autophagy [1].

Ionomycin is commonly used in conjunction with phorbol myristate acetate (PMA) to activate T cells [2]. This combination of PMA and ionomycin activates the transcription factors NF-κB and NFAT leading to the production of the cytokines, such as IL-2 [3, 4].
