INDEPENDENT RESEARCH

Research in the Nagy laboratory focuses on the role of small G proteins in mammary gland development and carcinogenesis. Various genetically engineered mouse lines are used as models in these investigations.

COLLABORATIVE RESEARCH

The Nagy laboratory is actively pursuing various collaborative research projects. These projects are quite diverse, mainly in the areas of infectious diseases (malaria, influenza, and tuberculosis), chemotherapy, and novel drug delivery methods. We provide expert histopathological analysis, digital photography of the histological lesions, and publication assistance for these projects.

IMMUNOPATHOGENESIS OF SEVERE MALARIA DURING PREGNANCY

Project period: 7/5/2007 – 4/30/2012 (5 years) 

Funding agency: NICHD/NIH 

PI: Julie Moore, PhD (Department of Infectious Diseases, UGA) 

Role: Co-Investigator 

Synopsis of the project: The main goal of this work has been to develop a mouse model for malaria during pregnancy using two distinct inbred mouse strains and use this model to identify key soluble immunologic effector molecules that play a role in malaria-induced pregnancy loss.

IMMUNOPATHOGENESIS OF SEVERE MALARIA DURING PREGNANCY

Project period: 7/5/2006 – 4/30/2012

Funding agency: NICHD/NIH 

Role: Co-Investigator 

PI: Julie M. Moore 

Role: Co-Investigator 

Synopsis of the project: The major goal of this project is to define the soluble immunologic mediators that are produced by pregnant animals in response to malaria that contribute to fetoplacental destruction and pregnancy loss.
