Asthma Research

Significant Accomplishments

Cooperative Research Grant

Our Asthma and Allergic Diseases Cooperative Research Center (AADCRC) is one of only 12 such centers in the United States.  Gurjit Khurana Hershey, MD, PhD, is the principal investigator for this center, which received a renewal of its NIH-funded U19 grant this year. 

The center’s overarching hypothesis is that epithelial cell genes play a central role in the pathogenesis of allergic disorders. Thus far, 10 peer-reviewed papers and five review articles and/or chapters have resulted from this grant.

Hershey, who also serves on the AADCRC steering committee, will continue to investigate the genetics of allergy-driven epithelial genes in children with asthma, atopic dermatitis and/or food allergy to identify shared and unique genes and pathways.

Inner City Asthma Consortium

Cincinnati Children’s was selected this year to join the NIAID-funded Inner City Asthma Research Consortium (ICAC).   The consortium, which includes 11 research centers, is the nation’s largest effort to study the factors that promote asthma in an inner city environment. Gurjit Khurana Hershey is the principal investigator for the Cincinnati Children’s subcontract.

The consortium’s objectives include conducting clinical studies to improve asthma control, prevent asthma among inner city children, and improve asthma phenotyping using validated biomarkers.  The group plans to conduct longitudinal birth cohort studies as well as mechanistic studies involving human subjects to gain information on the early immunopathogenesis of asthma, to identify asthma risk factors for inner city children, and to study the differences in the early immunopathogenesis of asthma between inner city and non-inner city children.  

Admixture Mapping in African American Asthmatic Children

This study proposes that disease does not affect all populations equally. Therefore, screening the genome of African American mixed ancestry can be an efficient strategy to identify asthma genes.  Tesfaye Mersha, PhD, is developing a program of study that would lead to an in-depth understanding of the genome of African American (AA) admixed populations and develop procedures and methods to localize asthma liability genes by utilizing this information and SNP markers for linkage disequilibrium admixture mapping.
