3,3/’,5-<wbr></wbr>Triiodo-<wbr></wbr>L-<wbr></wbr>thyronine (T3) is a thyroid hormone generated by deiodination of the prohormone thyroxine (T4). T3 is a potent agonist of both thyroid hormone receptors TRα and TRβ (K<sub>i</sub>s = 2.3 nM for both). Through TR signaling, T3 modulates such diverse processes as metabolism, cardiac function, growth, and redox signaling. T3 (sodium salt) is used both <em>in vitro</em> and <em>in vivo</em> to study the action of the TRs.
