This change can be identified rather quickly, and may be sustained weeks after the last dose of the drug.
Transgenic mice exhibiting inducible expression of ΔFos B primarily in the nucleus accumbens and dorsal striatum exhibit sensitized behavioural responses to cocaine.
Natural rewards, like drugs of abuse, induce gene expression of ΔFos B in the nucleus accumbens, and chronic acquisition of these rewards can result in a similar pathological addictive state through ΔFos B overexpression.
Research on the interaction between natural and drug rewards suggests that dopaminergic psychostimulants (e.g., amphetamine) and sexual behavior act on similar biomolecular mechanisms to induce ΔFos B in the nucleus accumbens and possess bidirectional reward cross-sensitization effects This phenomenon is notable since, in humans, a dopamine dysregulation syndrome, characterized by drug-induced compulsive engagement in natural rewards (specifically, sexual activity, shopping, and gambling), has also been observed in some individuals taking dopaminergic medications.
ΔFos B differs from the full length Fos B and further truncated Δ2ΔFos B in its capacity to produce these effects, as only accumbal ΔFos B overexpression is associated with pathological responses to drugs.Founded in 2002 by Nobel Laureate Carl Wieman, the Ph ET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations.Ph ET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery.

In other words, once "turned on" (sufficiently overexpressed) ΔFos B triggers a series of transcription events that ultimately produce an addictive state (i.e., compulsive reward-seeking involving a particular stimulus); this state is sustained for months after cessation of drug use due to the abnormal and exceptionally long half-life of ΔFos B isoforms.
