Pharmacological characterization of five cloned voltage-gated K+ channels, types Kv1.1, 1.2, 1.3, 1.5, and 3.1, stably expressed in mammalian cell lines.
We have analyzed the biophysical and pharmacological properties of five cloned K+ (Kv) channels (Kv1.1, Kv1.2, Kv1.3, Kv1.5, and Kv3.1) stably expressed in mammalian cell lines. Kv1.1 is…
The functional network of ion channels in T lymphocytes
The expression pattern of Ca2+ and K+ channels and hence the functional network can adapt depending upon the state of differentiation and activation, and this allows for different stages of an immune response to be targeted specifically.

TRAM-34 (1-[(2-chlorophenyl)diphenylmethyl]-1H-pyrazole) inhibits the cloned and the native IKCa1 channel in human T lymphocytes with a K(d) of 20-25 nM and is 200- to 1,500-fold selective over other ion channels, suggesting that TRAM- 34 and related compounds may hold therapeutic promise as immunosuppressants.

Molecular Properties and Physiological Roles of Ion Channels in the Immune System
This review surveys recent progress at the biophysical, molecular, and functional roles of the ion channels found in T lymphocytes, including K+, Ca2+, and Cl− channels.
Up-regulation of the IKCa1 Potassium Channel during T-cell Activation
Kv1.3 channels are essential for activation of quiescent cells, but signaling through the PKC pathway enhances expression of IKCa1 channels that are required for continued proliferation.
Blockade of the Intermediate-Conductance Calcium-Activated Potassium Channel as a New Therapeutic Strategy for Restenosis
Blockade of IKCa1 could represent a new therapeutic strategy to prevent restenosis after angioplasty and promote excessive neointimal VSMC proliferation.
