Wasting syndrome and disruption of the somatotropic axis in simian immunodeficiency virus-infected macaques with Mycobacterium avium complex infection.

Mycobacterium avium is a common opportunistic infection of patients with acquired immunodeficiency syndrome (AIDS). We used the simian immunodeficiency virus (SIV)-infected rhesus macaque (Macaca mulatta) model to examine whether disseminated M. avium is associated with disruption of the somatotropic axis in AIDS.

Alterations in expression of monocyte chemotactic protein-1 in the simian immunodeficiency virus model of disseminated Mycobacterium avium complex.

Mycobacterium avium complex (MAC) infection is the most common disseminated bacterial infection in untreated patients with acquired immunodeficiency syndrome (AIDS). We investigated the potential role of monocyte chemotactic protein-1 (MCP-1) in the pathogenesis of disseminated MAC, using the simian immunodeficiency virus (SIV)/macaque model of AIDS. Macaques were inoculated with SIV, followed by challenge with a pathogenic AIDS isolate of M.
