What we do…

The focus of research in the Lampe lab is understanding the role of drug metabolism and pharmacokinetics (DMPK) in drug efficacy within special population groups, with a particular emphasis on cytochrome P450 enzymes (CYP). Studies based on in vitro, structural, and computational models are used to gain more insight as to how neonates metabolize HIV drugs and the importance of CYP3A ontogeny in the liver. Research on how CYP polymorphisms in African Americans can lead to different pharmacokinetic and pharmacodynamic (PKPD) effects of certain antipsychotic drugs is also an area of active investigation in the laboratory. A third project is focused on studying the role of the ‘pathobiome’ in drug metabolism, particularly in cystic fibrosis patients. Lastly, the molecular mechanisms that underlie reproductive, developmental, and immunological toxicities in populations exposed to high levels of the man-made per- and polyfluoroalkyl substances (PFAS) is another research project area.

Research interests

In silico docking of 2α-hydroxytestosterone in CYP3A7
CYP3A7 in drug metabolism and toxicity in the neonate

This research project involves functional and computational modeling of HIV drug metabolism in the neonatal liver to accurately predict drug metabolism and disposition in the neonate and developing infant. Data generated from in vitro studies using CYP3A7 recombinant enzyme, a neonatal specific CYP isoform, and neonatal human liver microsomes are being modeled to define the QSAR of CYP3A7-mediated metabolism of HIV inhibitors and to build a PBPK model for the neonatal disposition and DDI risk of these HIV drugs using the GastroPlus® software package.

PFAS, the “forever chemicals”
PFAS and the dysregulation of oxylipins

PFAS, the “forever chemicals”, are associated with a wide variety of illnesses (hyperlipidemias, cancer, immunotoxicity, hepatotoxicity and developmental defects). The molecular mechanisms related to PFAS toxicities are not well understood. Via a collaboration with Dr. Rebecca McCullough, changes in oxylipin production and in inflammatory signals after PFAS exposure are being investigated as part of the hepatic response to these ubiquitous environmental contaminants.

Pseudomonas aeruginosa
Understanding the impact of Pseudomonas aeruginosa on drug metabolism and disposition

Little is known about the impact of the “pathobiome” on drug metabolism and disposition. During an infection, the pathogen is often the most abundant bacterial species present in the host and it has the potential to make a substantial contribution to the local metabolism and clearance of drugs. Our research goal is to study the ability of Pseudomonas aeruginosa, an important opportunistic pathogen of the lung in cystic fibrosis patients, to metabolize drugs and to understand how cytochrome P450 enzymes may contribute to this process.

Why we do it…

By understanding the differences in DMPK between the general adult population and understudied patient groups like neonates or African Americans, we are hoping in the long term to improve drug treatment which will lead to a better quality of care for these patients. We expect that our research will contribute to new and critical knowledge on drug therapy at the developmental, genetic and disease levels.
