Hypothesis
Alterations in gene expression relating to the immune system would be present in SHIV-infected animals despite the lack of clinical signs.
Conclusion
The study found significant gene expression differences in SHIV-infected monkeys compared to uninfected ones, indicating altered immune function.
Supporting Evidence
- Gene expression data showed significant variations between SHIV-infected and uninfected monkeys.
- SHIV-infected monkeys exhibited altered expression in genes related to immune regulation.
- Microarray analysis confirmed that gene expression patterns were distinct between infected and control groups.
Takeaway
Even though the monkeys looked healthy, their genes were behaving differently because of the virus, which could affect how they respond to other infections.
Methodology
Splenic tissue from SHIV-infected and uninfected Rhesus macaques was analyzed using cDNA microarray and real-time PCR.
Potential Biases
Potential bias due to the small sample size and the specific demographic of the monkeys studied.
Limitations
The study involved a small sample size and focused only on male Rhesus macaques of Indian origin.
Participant Demographics
Four adult male Indian-origin Rhesus macaques were SHIV-infected, compared to four unexposed male controls.
