Background:
Despite extensive research, the molecular/cellular underpinnings of bipolar disorder (BD) remain to be fully elucidated. Recent data has demonstrated that mood stabilizers exert major effects on signaling that regulate cellular plasticity; however, a direct extrapolation to mechanisms of disease demands proof that manipulation of candidate genes, proteins, or pathways result in relevant behavioral changes.
Methods:
We critique and evaluate the behavioral changes induced by manipulation of cellular plasticity cascades implicated in BD.
Results:
Not surprisingly, the behavioral data suggest that several important signaling molecules might play important roles in mediating facets of the complex symptomatology of BD. Notably, the protein kinase C and extracellular signal-regulated kinase cascades might play important roles in the antimanic effects of mood stabilizers, whereas glycogen synthase kinase (GSK)-3 might mediate facets of lithium's antimanic/antidepressant actions. Glucocorticoid receptor (GR) modulation also seems to be capable to inducing affective-like changes observed in mood disorders. And Bcl-2, amino-3-hydroxy-5-methylisoxazole-4-propionic acid receptors, and inositol homeostasis represent important pharmacological targets for mood stabilizers, but additional behavioral research is needed to more fully delineate their behavioral effects.
Conclusions:
Behavioral data support the notion that regulation of cellular plasticity is involved in affective-like behavioral changes observed in BD. These findings are leading to the development of novel therapeutics for this devastating illness.
Insights
Mood stabilizers impact cellular plasticity, influencing behaviors relevant to bipolar disorder (BD). Research links signaling molecules like GSK-3 and protein kinase C to BD symptoms and mood regulation.
Area of Science:
- Neuroscience
- Molecular Biology
- Psychiatry
Background:
- The precise molecular and cellular mechanisms underlying bipolar disorder (BD) are not fully understood.
- Mood stabilizers influence signaling pathways regulating cellular plasticity, but direct links to disease mechanisms require behavioral validation.
Purpose of the Study:
- To evaluate behavioral changes resulting from the manipulation of cellular plasticity cascades implicated in bipolar disorder.
Main Methods:
- Critically assessed behavioral outcomes from manipulating cellular plasticity pathways.
- Reviewed existing literature on signaling molecules and their behavioral effects in the context of BD.
Main Results:
- Signaling molecules like protein kinase C, extracellular signal-regulated kinase, and glycogen synthase kinase (GSK)-3 appear crucial for mood stabilizer effects in BD.
- Glucocorticoid receptor modulation and targets such as Bcl-2, AMPA receptors, and inositol homeostasis show potential in influencing affective behaviors.
Conclusions:
- Behavioral evidence supports the role of cellular plasticity regulation in affective changes associated with BD.
- These insights are paving the way for developing innovative therapeutics for bipolar disorder.
