Significant differences in the subgroup depression (first-episode and recurrent depression) were also shown in 3 genotypes of S100B rs9722 and rs11911834 in patients and control subjects (P < 0.05).
Although it may be open for discussion whether the neuroprotective effects of ONO-2506 are exclusively due to its inhibition of S100B synthesis, the latter action of ONO-2506 warrants studies of the effects of this drug in the pathobiology of depression.
S100 beta, a calcium binding brain protein expressed by astrocytes, has been shown to be involved in higher neural processes, including hippocampal-dependent behavioral traits and hippocampal neuronal long-term potentiation (LTP) and depression (LTD), neurophysiological phenomena that may be involved in exploring, learning and remembering novel stimuli.
S100 beta, a calcium binding astrocytic brain protein, influences hippocampal long-term potentiation (LTP) and depression (LTD), synaptic processes suggested to play role in spatial (contextual) learning and memory.
