Mechanisms of L-Triiodothyronine-Induced Inhibition of Synaptosomal Na⁺-K⁺-ATPase Activity in Young Adult Rat Brain Cerebral Cortex

Figure 2

Inhibitory effect of various doses (0.001 nM–10 nM) of T₄ or T₂ on synaptosomal Na⁺-K⁺-ATPase activity, in vitro. The data are represented as mean ± SEM of four separate experiments, taking six animals in each group. The vertical lines denote SEM. Filled circles indicate effects of T₄ on Na⁺-K⁺-ATPase activity while filled squares indicate effects of T₂.
