Courses Taught

BIOC5125Q   Viruses, Cells and Disease

EDUC7001K   Infection & Host Response

Infection and Host Response is an intensive course in which much information must be communicated in a relatively short period of time. Attendance at all lectures is highly recommended. Students will receive basic information through lectures and small group case discussions. They will be expected to assimilate and use the information presented. On-line laboratories will emphasize the properties of infectious agents and histopathology of infectious disease. Students participate in two types of small group case discussions. POPS (Patient-Oriented Problem Solving) cases are group-led and students will receive a grade based on their participation. Small group infectious disease cases are led by 4th year medical students. Attendance will be taken at all these sessions and preparation and participation will be graded. The course is divided into three units. Each unit ends with a unit exam. At the end of the course, there is a comprehensive subject examination (Shelf).

Host-virus interactions in oncogenic herpesviral infection

Kaposi's Sarcoma-Associated Herpesvirus (KSHV; also known as Human herpesvirus-8) is a DNA tumor virus that is the etiologic agent of Kaposi's Sarcoma and other AIDS-related cancers. Epidemiologic studies have demonstrated that lytic reactivation of KSHV from latency is required for progression of these unique cancers. We are studying the critical host-virus interactions, at the molecular level, that govern reactivation of the virus, in order to gain a thorough understanding of the pathogenesis of KSHV infection.

We have previously demonstrated that a single viral protein, called Rta (for "replication and transcriptional activator"), functions as a molecular switch controlling the induction of the virus from latency. For these studies, we have developed a number of quantitative assays for measuring viral reactivation and replication in response to various proteins and stimuli. We have also determined that Rta's critical role in reactivation is to transcriptionally transactivate viral and cellular promoters in combination with other host and viral proteins. We have identified two of these cellular proteins, and we are characterizing the DNA/protein interactions that are critical for viral reactivation. We are also deciphering Rta's function by investigating its mechanisms of interaction with heterologous viral proteins. Finally, we are committed to determining the molecular regulation of progression of the viral lytic cycle in which many of the viral oncogenes are expressed.
