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 …

In the absence of hearing, the brain must adapt and repurpose the former auditory cortex. In this study we scanned normal hearing (n=29) and deaf (n=26) cats to identify cortical areas of differing thickness using the auditory regions from a 3D cortical atlas. Compared to hearing controls, differential thickening and thinning was observed in specific regions of the deaf auditory cortex. More dorsal auditory regions tended to be bilaterally thicker in the deaf group, while more ventral regions in the left hemisphere were thinner. The location and nature of these changes creates a gradient along the dorsoventral axis wherein dorsal …
