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.
