Animal models for HIV AIDS: a comparative review.
Human immunodeficiency virus (HIV), the causative agent for acquired immune deficiency syndrome, was described over 25 y ago. Since that time, much progress has been made in characterizing the pathogenesis, etiology, transmission, and disease syndromes resulting from this devastating pathogen. However, despite decades of study by many investigators, basic questions about HIV biology still remain, and an effective prophylactic vaccine has not been developed. This review provides an overview of the viruses related to HIV that have been used in experimental animal models to improve our knowledge of lentiviral disease. Viruses discussed are grouped as causing (1) nonlentiviral immunodeficiency-inducing diseases, (2) naturally occurring pathogenic infections, (3) experimentally induced lentiviral infections, and (4) nonpathogenic lentiviral infections. Each of these model types has provided unique contributions to our understanding of HIV disease; further, a comparative overview of these models both reinforces the unique attributes of each agent and provides a basis for describing elements of lentiviral disease that are similar across mammalian species.
