Delta fosb and addiction

WebDelta FosB is a truncated splice variant of FosB. [4] Delta FosB has been implicated in the development of drug addiction and control of the reward system in the brain, and is linked to changes in a number of other gene products such as CREB and sirtuins. WebWe show here that chronic, but not acute, administration of each of four drugs of abuse, cocaine, morphine, ethanol, and Delta (9)-THC, robustly induces DeltaFosB in nucleus accumbens, although different patterns in the core vs. shell subregions of this nucleus were apparent for the different drugs.

WebJun 12, 2014 · Environmental enrichment produces protective addiction and depression phenotypes in rats. ΔFosB is a transcription factor that regulates reward in the brain and is induced by psychological stress as well as drugs of abuse. However, the role played by ΔFosB in the protective phenotypes of environmental enrichment has not been well studied.

WebΔFosB is the most significant biomolecular mechanism in addiction because the overexpression of ΔFosB in the D1-type medium spiny neurons in the nucleus accumbens is necessary and sufficient for many of the neural adaptations and behavioral effects (e.g., expression-dependent increases in drug self-administration and reward sensitization) … WebAbstract. Regulation of gene expression is one mechanism by which drugs of abuse can induce relatively long-lasting changes in the brain to cause a state of addiction. Here, we focus on two transcription factors, CREB (cAMP response element binding protein) and DeltaFosB, which contribute to drug-induced changes in gene expression.
