Silvia M. Kreda, PhD

Associate Professor

Specialty Areas:

Regulation of mucin secretion and nucleotide release in airway epithelial cells. Targeting of therapeutic molecules to the airway epithelium.

Research Focus:

Dr. Kreda’s research focusses in identifying signaling molecules/pathways that regulate airway mucin secretion. The main goal is to uncover potential targets of clinical interest to control abnormal lumenal mucus accumulation in lung diseases. Her lab has developed and optimized in vitro and in vivo models of lung diseases and quantitative assays for therapeutic drug testing and evaluation of mucin production in airway epithelia.

Dr. Kreda’s lab also studies mechanisms of molecule uptake in the airway epithelia. The main goal is to develop novel and efficacious delivery strategies of therapeutic agents and nucleic acids in obstructive lung diseases.

Funding sources for Dr. Kreda’s lab include Cystic Fibrosis Foundation, National Institutes of Health (NIH), NCTraCS (the NIH CTSA at UNC-CH), AstraZeneca, and Forest Research Institute (now AstraZeneca).

Her lab has successful collaborations with scientists from academic and pharmaceutical institutions to develop and test novel drugs for their potential therapeutic use in obstructive lung diseases. For more information contact .
