Research Interests

In collaboration with Dr. Goldring, Taylor and Kemeny, Dr. Anton has studied the impact of health beliefs, quality of life and the physician-patient relationship on the treatment intentions of inflammatory bowel disease patients.

 

The research tested a model of treatment decision-making in chronic illness that includes health beliefs, quality of life (disease activity and functional impairment), and relationship with the physician (shared or not). The findings suggest that an integrative consideration of relationship factors, health beliefs, and health status may help explain treatment intentions among the chronically ill. Other studies with Dr. Tache have investigated the role of central neuropeptides in an animal model of inflammatory bowel disease as a member of the PNI Task Force for the Cousins Center for PNI since 1990 For the past 7 years, his research has focused primarily on HIV pathogenesis in the gastrointestinal mucosa and prevention strategies.

Current research

Impact of co-receptor and HIV viral burden on gut mucosa
Principal Investigator: Anton
Agency: NIH/NIAID
Type: K24 AI 01610 Period: 4/1/00-3/31/05

The aims of the project are to optimize HIV quantitative tissue assays using endoscopic biopsies and characterization of mucosal mononuclear cells in the setting of HIV infection. The tools are to be used to correlate tissue viral burden with co-receptor expression in mucosa and investigate in vitro susceptibility to infection of mucosal cells from healthy and inflamed biopsies from HIV-negative subjects. Interventional trials using anti-inflammatory agents are planned. Mentoring is a large component of this project.

UCLA Center for AIDS Research (CFAR) Core for Mucosal Immunology
Principal Investigator: Chen
Agency: NIH/NIAID
Type: P30 AI-28697 Period: 9/1/99 - 6/30/03

The major goal of this project is to assist the development of HIV-related mucosal immunology projects as a Core facility including study design, patient access, assistance in IRB applications and tissue acquisition. This funding assists in providing the infrastructure for investigator access to mucosal tissue by supporting the development of reproducible methods for intestinal biopsy tissue acquisition and sample preparation.
