a) Network of ion channels and transporters in human T cells. KV1.3 and KCa3.1 are expressed in both the plasma membrane and inner mitochondrial membrane. Although CaV3.2, CaV3.3, CaV2.1 transcripts are present in T cells, they lack many 5’ exons and consequently no functional CaV channels are expressed in T cells [10]. This figure is modified and updated from a figure published in [9]. b) The number of KV1.3 and KCa3.1 channels per T cell in quiescent, acutely activated (1–3 rounds of antigenic stimulation) and chronically activated (>4–5 rounds of antigenic stimulation) cells.
