Eric J. Nestler is the Nash Family Professor of Neuroscience, Director of the Friedman Brain Institute, and Dean for Academic Affairs at the Icahn School of Medicine at Mount Sinai and Chief Scientific Officer of the Mount Sinai Health System. [1] [2] [3] His research is focused on a molecular approach to drug addiction and depression.
He is the co-author of four books and more than 725 peer-reviewed articles, and he serves as principal investigator or co-principal investigator on 8 NIH grants.
Nestler is a graduate of Herricks High School in New Hyde Park, New York. He received his B.A., his Ph.D. and his M.D. from Yale University, where he performed his doctoral research in the laboratory of Paul Greengard. He completed his residency in psychiatry at both McLean Hospital in Massachusetts and Yale in 1987. [1]
Nestler served as Director of the Abraham Ribicoff Research Facilities, as the Founding Director of the Division of Molecular Psychiatry at Yale until 2000, and as Chairman of the Department of Psychiatry at the University of Texas Southwestern Medical Center at Dallas. [1] He joined Mount Sinai in 2008. He has served on the Boards of Scientific Counselors of the National Institute on Drug Abuse and of the National Institute on Alcohol Abuse and Alcoholism, on the National Advisory Mental Health Council for the National Institute of Mental Health, the National Advisory Drug Abuse Council for the National Institute on Drug Abuse, [4] as Council Member of the American College of Neuropsychopharmacology (for which he served as president in 2011) and the Society for Neuroscience (for which he served as president in 2017). He is a member of the Scientific Advisory Board of the Brain & Behavior Research Foundation (BBRF, previously NARSAD) and of One Mind (previously International Mental Health Research Organization), [5] as well as a past member of the Board of Directors of the McKnight Endowment Fund in Neuroscience. [6] He was elected to the Institute of Medicine (now National Academy of Medicine) in 1998 and the American Academy of Arts and Sciences in 2005. [6] [7]
The Nestler laboratory's focus in neuropsychopharmacology and molecular neuroscience concentrates on forming a molecular approach to psychiatry and furthering the understanding of the molecular basis of both depression and drug addiction, using animal models to study the way drug use or stress affects the brain. [1] His addiction research largely centers around several transcription factors, including ΔFosB and CREB (master control proteins that induce addiction or depression in vulnerable individuals or resistance to these syndromes in resilient individuals) and the associated epigenetic remodeling that occurs in specific neuronal or glial cell types in the brain. A major goal is to identify the ‘chromatin scars’—long lasting epigenetic changes at specific genomic loci—that mediate lifelong changes in disease vulnerability. Among the prominent targets of this work are medium spiny neurons of the nucleus accumbens and pyramidal neurons in prefrontal cortex and ventral hippocampus. [3] [8] [9] The Nestler laboratory has driven innovative use of viral-mediated gene transfer, inducible, cell-type specific mutations in mice, and locus-specific epigenome editing to establish causal links between molecular and behavioral phenomena in animal models. [8] [9] [10] The laboratory also makes creative use of advanced machine learning approaches to derive novel biological insight from large sequencing datasets.

The mesolimbic pathway, sometimes referred to as the reward pathway, is a dopaminergic pathway in the brain. The pathway connects the ventral tegmental area in the midbrain to the ventral striatum of the basal ganglia in the forebrain. The ventral striatum includes the nucleus accumbens and the olfactory tubercle.
Dynorphins (Dyn) are a class of opioid peptides that arise from the precursor protein prodynorphin. When prodynorphin is cleaved during processing by proprotein convertase 2 (PC2), multiple active peptides are released: dynorphin A, dynorphin B, and α/β-neoendorphin. Depolarization of a neuron containing prodynorphin stimulates PC2 processing, which occurs within synaptic vesicles in the presynaptic terminal. Occasionally, prodynorphin is not fully processed, leading to the release of "big dynorphin". "Big dynorphin" is a 32-amino acid molecule consisting of both dynorphin A and dynorphin B.
Protein c-Fos is a proto-oncogene that is the human homolog of the retroviral oncogene v-fos. It is encoded in humans by the FOS gene. It was first discovered in rat fibroblasts as the transforming gene of the FBJ MSV. It is a part of a bigger Fos family of transcription factors which includes c-Fos, FosB, Fra-1 and Fra-2. It has been mapped to chromosome region 14q21→q31. c-Fos encodes a 62 kDa protein, which forms heterodimer with c-jun, resulting in the formation of AP-1 complex which binds DNA at AP-1 specific sites at the promoter and enhancer regions of target genes and converts extracellular signals into changes of gene expression. It plays an important role in many cellular functions and has been found to be overexpressed in a variety of cancers.
The reward system is a group of neural structures responsible for incentive salience, associative learning, and positively-valenced emotions, particularly ones involving pleasure as a core component. Reward is the attractive and motivational property of a stimulus that induces appetitive behavior, also known as approach behavior, and consummatory behavior. A rewarding stimulus has been described as "any stimulus, object, event, activity, or situation that has the potential to make us approach and consume it is by definition a reward". In operant conditioning, rewarding stimuli function as positive reinforcers; however, the converse statement also holds true: positive reinforcers are rewarding.
Methamphetamine is a potent central nervous system (CNS) stimulant that is mainly used as a recreational drug and less commonly as a second-line treatment for attention deficit hyperactivity disorder and obesity. Methamphetamine was discovered in 1893 and exists as two enantiomers: levo-methamphetamine and dextro-methamphetamine. Methamphetamine properly refers to a specific chemical substance, the racemic free base, which is an equal mixture of levomethamphetamine and dextromethamphetamine in their pure amine forms, but the hydrochloride salt, commonly called crystal meth, is widely used. Methamphetamine is rarely prescribed over concerns involving human neurotoxicity and potential for recreational use as an aphrodisiac and euphoriant, among other concerns, as well as the availability of safer substitute drugs with comparable treatment efficacy such as Adderall and Vyvanse. Dextromethamphetamine is a stronger CNS stimulant than levomethamphetamine.
Transcription factor JunD is a protein that in humans is encoded by the JUND gene.
Euchromatic histone-lysine N-methyltransferase 2 (EHMT2), also known as G9a, is a histone methyltransferase enzyme that in humans is encoded by the EHMT2 gene. G9a deposits the mono- and di-methylated states of histone H3 at lysine residue 9 and lysine residue 27. The presence of H3K9me1/2 is usually associated with gene silencing.
Protein fosB, also known as FosB and G0/G1 switch regulatory protein 3 (G0S3), is a protein that in humans is encoded by the FBJ murine osteosarcoma viral oncogene homolog B (FOSB) gene.
PPAR agonists are drugs which act upon the peroxisome proliferator-activated receptor. They are used for the treatment of symptoms of the metabolic syndrome, mainly for lowering triglycerides and blood sugar.
Cocaine addiction is the compulsive use of cocaine despite adverse consequences. It arises through epigenetic modification and transcriptional regulation of genes in the nucleus accumbens.
Behavioral epigenetics is the field of study examining the role of epigenetics in shaping animal and human behavior. It seeks to explain how nurture shapes nature, where nature refers to biological heredity and nurture refers to virtually everything that occurs during the life-span. Behavioral epigenetics attempts to provide a framework for understanding how the expression of genes is influenced by experiences and the environment to produce individual differences in behaviour, cognition, personality, and mental health.
Addiction is a state characterized by compulsive engagement in rewarding stimuli, despite adverse consequences. The process of developing an addiction occurs through instrumental learning, which is otherwise known as operant conditioning.
Alcino J. Silva is a Portuguese-American neuroscientist who was the recipient of the 2008 Order of Prince Henry and elected as a fellow of the American Association for the Advancement of Science in 2013 for his contributions to the molecular cellular cognition of memory, a field he pioneered with the publication of two articles in Science in 1992.
Addiction vulnerability is an individual's risk of developing an addiction during their lifetime. There are a range of genetic and environmental risk factors for developing an addiction that vary across the population. Genetic and environmental risk factors each account for roughly half of an individual's risk for developing an addiction; the contribution from epigenetic risk factors to the total risk is unknown. Even in individuals with a relatively low genetic risk, exposure to sufficiently high doses of an addictive drug for a long period of time can result in an addiction. In other words, anyone can become an individual with a substance use disorder under particular circumstances. Research is working toward establishing a comprehensive picture of the neurobiology of addiction vulnerability, including all factors at work in propensity for addiction.

Epigenetics of depression is the study of how epigenetics contribute to depression.
H3K9me2 is an epigenetic modification to the DNA packaging protein Histone H3. It is a mark that indicates the di-methylation at the 9th lysine residue of the histone H3 protein. H3K9me2 is strongly associated with transcriptional repression. H3K9me2 levels are higher at silent compared to active genes in a 10kb region surrounding the transcriptional start site. H3K9me2 represses gene expression both passively, by prohibiting acetylation as therefore binding of RNA polymerase or its regulatory factors, and actively, by recruiting transcriptional repressors. H3K9me2 has also been found in megabase blocks, termed Large Organised Chromatin K9 domains (LOCKS), which are primarily located within gene-sparse regions but also encompass genic and intergenic intervals. Its synthesis is catalyzed by G9a, G9a-like protein, and PRDM2. H3K9me2 can be removed by a wide range of histone lysine demethylases (KDMs) including KDM1, KDM3, KDM4 and KDM7 family members. H3K9me2 is important for various biological processes including cell lineage commitment, the reprogramming of somatic cells to induced pluripotent stem cells, regulation of the inflammatory response, and addiction to drug use.

Chronic exposure to stress or drugs of abuse causes widespread changes in the activity of chromatin remodelling enzymes. However, it has been difficult to determine the relative functional importance of drug- or stress-induced epigenetic modifications of individual genes. Nestler and colleagues have now employed gene- and brain-region-specific chromatin remodelling to examine the role of one particular gene, [ΔFosB], in addiction- and depression-related changes in the brain and behaviour. ... This study shows that single epigenetic modifications can modulate both [ΔFosB] expression and its behavioural effects. A similar approach may be used to target other genes of interest and elucidate further the changes in molecular pathways that underlie psychiatric disorders.
Dr. Nestler, in Chapter 4, presents an extremely creative and potentially groundbreaking view of the molecular mechanisms and neural circuitry of reward and how they might relate to vulnerability to addictive behaviors. ... Dr. Nestler focuses on two transcription factors, CREB (cAMP response element binding protein) and ΔFosB
