This webinar introduces the use of the human immunodeficiency virus (HIV) in the huNOG mouse for better preclinical drug candidate selection and combotherapy profiling. HIV is a human specific virus targeting human CD4 positive circulating lymphocytes. During the past 10 years, the development of the reconstitution of a fully functional human immune system in NOG mice (huNOG) has provided the opportunity to setup HIV huNOG mouse models.

After 15 weeks of reconstitution, huNOG mice can be infected intraperitoneally with HIV, and 3-4 weeks later, in vivo profiling of new anti-HIV drug candidates can be initiated. Typically, we assess efficacy, resistance, rebound, latency and combotherapy, as HIV infection leads to a stable and elevated viral load in the blood. Conventional HAART therapy for 3 weeks decreases by 95% the circulating viral load, and treatment cessation induces a rebound as observed in HIV/AIDS patients. Different HIV strains can be used for the successful infection of huNOG. Cytolytic and cytopathic effects have been studied on hu-CD4 positive lymphocytes from HIV mice.

In addition, we will report on various routes of infection and the development of a vaginal infection protocol which allow the profiling of anti-HIV vaginal gels. HuNOG models have an important role in all aspects of HIV research including, but not restricted to, the characterization of successful medical anti-HIV prevention strategies, the evaluation of new treatment regimens, and the evaluation of novel HIV eradication strategies.
