Oral Combinational Antiretroviral Therapy to Treat HIV-1 Infection in a Humanized Mouse Model
Published: April 30, 2024
Abstract
Source: Mu, W., et al. Oral Combinational Antiretroviral Treatment in HIV-1 Infected Humanized Mice. J. Vis. Exp. (2022).
This video demonstrates an assay to evaluate the effectiveness of oral combined antiretroviral therapy (oral cART) in a human immunodeficiency virus-1 (HIV-1)-infected humanized mouse model. A combination of drugs targeting HIV-1, including nucleoside reverse transcriptase inhibitors and integrase strand transfer inhibitors, is administered along with a nutritional supplement and antibiotics. Following the consumption of this mixture by the humanized mice infected with HIV-1, the effective suppression of viral replication is assessed through periodic examinations of the mice.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Humanized mice infected with HIV-1 NOTE: Humanized mice were constructed as previously described. The protocol is briefly described below. Purify CD34+ hematopoietic progenitor cells from the human fetal liver via anti-CD34 microbeads according to the manuf…
