Investigator: Creative and Novel Ideas in HIV Research (CNIHR) Award
Title: Epigenetic modulation rescues virus-specific CD8+ T cells from
T regulatory cell suppression.
Description: These studies are aimed at identifying the mechanisms of
CD8+ T cell suppression and how to rescue virus-specific CD8+
proliferation using the FIV model for HIV.
Role: PI

Investigator: R21 LM11A-31 (Meeker, PI)
Title: LM11A-31 neuroprotective efficacy in an animal model of HIV
Description: Examination of a novel compound LM11A-31 for
neuro-protective effects using the FIV model
Role: Co-I

Investigator: Soluble C14 as a biomarker for bacterial translocation.  The Clinical Immunology facility, in collaboration with the Clinical Studies Core and Equine Health Sciences Program at the NCSU-CVM, is conducting a study to assess the utility of sCD14 as a biomarker for bacterial translocation in horses, dogs and cats.

Co-investigator: Phenotypic and functional characterization of differences between monocytes in dogs with and without osteosarcoma. The purpose of this study is to acquire a deeper understanding of the heterogeneity of canine monocytes by defining monocyte subpopulations, with specific emphasis on monocytes in dogs with osteosarcoma that also have an infected surgical site.
