The non-human primate model of tuberculosis.

Area of Science:

• Comparative medicine
• Infectious disease research
• Primate models

Background:

• Non-human primates (NHPs) share significant genomic, physiological, and immunological similarities with humans.
• There is a growing emphasis on utilizing NHPs for modeling human diseases, particularly tuberculosis (TB).

Purpose of the Study:

• To review recent advances in the use of non-human primate models for tuberculosis research.
• To highlight the utility of NHPs in studying TB pathogenesis, immune responses, and preclinical testing.

Main Methods:

• Macaques are infected with Mycobacterium tuberculosis (Mtb) via various routes and doses.
• Disease outcomes in NHPs range from latent infection to acute TB, mimicking human conditions.

Main Results:

• NHP models recapitulate the spectrum of human TB, including latent and active disease.
• These models are crucial for preclinical evaluation of novel TB vaccines and therapeutics.
• NHPs enable investigation into key TB biology questions, such as the impact of hypoxia and latent TB reactivation.

Conclusions:

• Non-human primates, particularly macaques, are highly relevant models for human tuberculosis.
• The NHP model is instrumental for advancing our understanding of TB pathogenesis and developing effective interventions.
