This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.The purpose of this research project is study the interactions of the fungus, Aspergillus fumigatus, with endothelial cells. These cells form the inner lining of the blood vessels. The long-range goal of this research is to understand how A. fumigatus invades, stimulates, and damages these cells so that methods to block this processes can be developed. This work is important because the mortality of patients with a disseminated candidal infection is approximately 50%, even with currently available therapy. For the proposed studies, the endothelial cells will be harvested from the veins within human umbilical cords and grown in tissue culture. The umbilical cords will be obtained after normal vaginal births from uninfected donors. No information about the mother or baby will be collected. The donors of the cords will not be identified and the umbilical cord blood will not be collected. The umbilical cords will collected at both Harbor-UCLA Medical Center and at Cedars-Sinai Medical Center. This study will also study the interactions of A. fumigatus with the A549 type 2 pneumocyte cell line. This cell line was originally isolated from a human with lung cancer in 1972. It will be obtained from the American Type Culture Collection. There is no information linking the identity of the this patient with the cell line.
