Dr. Looney's C.V.


Background

Dr. Looney graduated from the University of Missouri School of Medicine in 1979 and performed his internship and residency training at Letterman Army Medical Center in San Francisco. His infectious disease fellowship was done at the Brook Army Medical Center in San Antonio, TX, and the the Texas State Chest Hospital and Hansen's Disease Center in San Antonio. He completed training in Tropical Medicine at the Walter Reed Army Insitute of Research, and did postdoctoral training in the laboratory of Dr. Flossie Wong-Staal at the NCI Laboratory of Tumor Cell Biology.

Since coming to UCSD in 1989, Dr. Looney has conducted both basic and clinical research involving HIV vaccine, Gene Therapy of HIV infection, Kaposi's Sarcoma, and investigations into the role of small RNAs in transcriptional silencing and HIV replication. He current is leader of the Center for AIDS Research Molecular Biology Core, which provides support to HIV-investigators and developmental projects.

Research Interests

Areas of basic science research interest include : (1) Gene therapy of HIV/AIDS using lentiviral vectors expressing RNAs (ribozymes, antisense RNA, or siRNA directed against HIV/SIV or cellular needed cofactors) which inhibit HIV-1/SIV replication, (2) Transcriptional Silencing of HIV and other promoters via RNA Interference, mechanism and application, (3) Role of microRNA in HIV replication, (4) Effect of VelcadeTM (bortezomib - proteasome inhibitor) on EBV and KSHV replication, and (5) Genetic engineering of antigen presenting cells to more effectively present antigen using siRNA knock-out of inhibitory pathways.

Clinical research activities include: (1) Serving as local site and/or principal investigator for the multicenter/ multinational VA Cooperative Studies OPTIMA (Options in Management with Antiretrovirals) study, (2) Participating in antiretroviral phase I and expanded access studies (TMC114, TMC125, MK0518, Maraviroc), (3) Principal Investigator for evaluation of Gen-Probe qualitative HIV RNA as a screening test for clinical virological suppression, (4) Serving as co-investigator and site PI on an HIV medication adherence project (ACASI), (5) Participating in CTEP trials related to viral and/or AIDS-associated malignancies as a site co-investigator, and (6) Serving as study physician on the Shingle Prevention Study and Long Term Persistence Substudy (LTPS).
