Research Interests

Viral Pathogenesis and Therapy (HIV and AIDS)
Biomarkers for Infectious Diseases and Cancer

Dr. Paul Luciw is a virologist with extensive experience in many aspects of virology, cell biology, and molecular biology. The main emphasis of his research is on viruses that establish persistent infection; these include retroviruses that cause immunodeficiency and herpesviruses associated with cancer. His recent translational research has focused on the development of novel technologies for studies of infectious diseases and cancer.

Mechanisms of Viral Pathogenesis and Latency

For studies on simian immunodeficiency virus (SIV), a major aim of Dr. Luciw's research is to identify viral determinants of pathogenesis in the non-human primate model (i.e., rhesus monkeys) for AIDS. This research aims to define functional domains on viral proteins and to analyze molecular mechanisms regulating viral transcription in latency and reactivation. He is testing novel pharmacologic approaches targeted at inducing virus (SIV or HIV) from latent cell reservoirs. Coupled with highly active antiretroviral therapy, induction of latent virus by compounds that activate specific transcription factors and remodel chromatin, could lead to elimination of virus from an infected individual. Dr. Luciw's collaborative studies on the oncogenic herpesvirus, Kaposi's sarcoma-associated herpesvirus (KSHV), are focused on viral genes regulating signal transduction and transcription and on post-translational modifications of chromatin proteins during viral infection. The goal is to understand the molecular mechanisms by which this oncogenic herpesvirus alters cell functions to favor viral replication and mediate tumorigenesis. 

Translational Research for Infectious Diseases and Cancer

For translational research of infectious diseases, Dr. Luciw has developed multiplex immunoassay technology for detection of antibodies to multiple infectious agents and analysis of host response immunomodulatory proteins to infection. To study host responses to Mycobacterium tuberculosis, his laboratory has used multiplex immunoassays for studies of cytokines, chemokines, and inflammatory mediators as well as antibodies to multiple antigens of this pathogen in nonhuman primates and humans. Importantly, these robust multiplex assays have strong potential for significantly improving diagnosis and prognosis of tuberculosis. He has also applied this novel immunoassay for detection of antibodies to multiple infectious agents of mouse (UC Davis Mouse Biology Program) and rhesus monkey (California Primate Center). For application to studies on mechanisms of tumorigenesis, Dr. Luciw has been developing multiplex immunoassay systems that simultaneously detect multiple cell signaling molecules (phosphotyrosine kinsease and substrates, phosphoserine/threonine kinsese and substrates, transcription factors). This system enables simultaneous analysis of multiple signal transduction pathways and multiple components of these pathways in cancer cell line models and tumors. His laboratory also performs multiplex analysis of protein targets in plasma of cancer patients, with the goal of defining rapid and effective methods for diagnosis and prognosis. These plasma targets include include biomarkers associated with various stages of tumorigenesis (growth factors, proteinases, oncogenes, angiogenesis factors, etc.).
