Justin Harper received his M.A. in Biochemistry and Cell Biology in 2013 from Rice University studying the atomic resolution structure of RNA viruses by transmission electron microscopy and X-ray crystallography under Dr. Jane Tao. He joined the Paiardini lab as a Research Specialist in 2015 and transitioned into the lab manager position in 2018. Using SIV-infected macaques, his prior areas of interest include (1) the characterization of immune checkpoint receptors as a biomarker for enriched viral content; (2) determining if combination immune checkpoint blockade synergistically reactivates latent SIV; (3) evaluating the role of IL-10 signaling in promoting the maintenance of CD4+ T cell subsets that contribute to viral persistence; and (4) investigating novel immunotherapy approaches to induce natural killer (NK) cell maturation in vivo. Using CD4-depleting monoclonal antibodies to shift the distribution of the viral reservoir between CD4+ T cells and macrophages, he is currently investigating how macrophages are productively infected and determine if they persist with long-term ART.
