This project sought to perform the in vitro work needed to accomplish the long-term vision of harnessing the similarities between HIV (Human Immunodeficiency Virus) and FIV (Feline Immunodeficiency Virus) to develop an animal model whereby cats can be used to study HIV pathogenesis and therapeutics. We transfected CRFK (Crandell Rees Feline Kidney) fibroblasts with plasmids that could express human or feline CD4, CCR5, or both, and determined receptor surface expression through flow cytometry. We discovered that HIV envelope expressed on 293T can fuse with huCD4/huCCR5 on CRFK. These cat cell lines were also capable of supporting HIV infection. Additionally, we …

Although several studies have determined key differences in envelope motifs between TF and chronic HIV-1, it is still not known what the overall glycosylation profile is that is selected for in a transmission event, as well as what contributes to this selection. Using a bottom-up approach of modifying specific viruses, determining their transmission fitness in an ex vivo tissue explant assay, and determining their glycan content, we have laid the basis for determining the overall glycan structure which is selected for in TF HIV-1. Preliminarily, we have shown that C-type lectins represent a stringent barrier to transmission and have several …
