Narrative Description of Research:

The focus of the Kosofsky laboratory is to apply molecular, anatomic, behavioral, and electrophysiologic methods to characterize the effects of cocaine on developing brain. Clinical data suggests that infants exposed to cocaine in utero demonstrate a spectrum of structural and behavioral deficits, implying altered CNS maturation consequent to gestational drug exposure. We have created an animal model, in mice and rats, to identify growth, behavioral and neuroanatomic consequences of transplacental cocaine exposure, and to characterize molecular mechanisms whereby brain development is modified. Observations to date include:

By administering cocaine during critical developmental periods we have reproduced both the growth retardation (including brain and body), and an inattention syndrome. By performing restricted gestational administration and dose fractionation experiments we have been able to dissociate the growth effects from the behavioral effects; lower doses of cocaine and less severe malnutrition impair brain and body growth, but do not have effects on the ontogeny of learning a conditioned aversion, or on the ability of adult animals to demonstrate blocking (i.e., selective attention).

We have found that the brains of mice exposed to cocaine in utero are thinner, with an imprecision in the horizontal organization of cortical lamination, with an admixture of cell types across individual layers. In addition there is a thinning of the axo-dendritic bundles. In thymidine "birth dating" studies we have shown that cells born synchronously are widely dispersed through multiple neocortical layers.

We have made progress understanding some of the molecular correlates of the inattention syndrome induced in mice exposed to cocaine in utero. We have demonstrated that the G-coupled protein that positively couples aminergic receptors (norepinephrine-B; serotonin-4,6,7; dopamine-1,5) to cAMP (Gs) is 40-60% blunted in response.

In other experiments, we have demonstrated altered expression of a class of transcription factors termed immediate early genes, which occurs at short time points after acute postnatal cocaine exposure. Moreover, the specific immediate early genes altered, and the particular cells in specific brain regions affected varies with the developmental age of the animal studies. Recent experiments are directed at establishing the relationship of these early molecular changes in IEG expression with the lasting structural and behavioral alterations we have defined, and to identify determinants underlying and consequences resulting from the spatial and temporal specificity of drug-induced gene dysregulation.

Molecular methods employed include northern gel analysis and gel shift experiments; anatomic studies include immunohistochemistry and histochemical methods (for evaluation of transgenic mice); behavioral experiments are conducted in juvenile and adult animals (including "knockouts"). We have combined molecular approaches with anatomic studies by developing in situ hybridization histochemistry (ISHH) methods, including non-radioactive ISHH. Current efforts are directed at correlating behavioral findings with drug-induced molecular and neuroanatomic perturbations, to better understand how cocaine-induced changes in gene expression result in permanent alterations in brain structure and function.

Self Report of Clinical Activities:


In addition to Attending at MGH in (Child) Neurology one month each year, and in Pediatrics two weeks each year, Dr. Kosofsky established and directs SAEF Clinic (Substances of Abuse Exposure Follow-up) in the Department of Neurology at MGH. This weekly clinic session coordinates the evaluation of infants and children who have sustained prenatal exposure to substances of abuse (alcohol, cocaine, and other drugs). This multidisciplinary clinic coordinates referrals for substance-abusing mothers through MGH Addiction Services, and provides care for substance-exposed children, specializing in diagnosis and management of the unique problems evident in this population.
