Primates share certain characteristics with humans. What are these characteristics that make them valuable in research?

• A. Immunological similarities and susceptibility to similar diseases, making them valuable
• B. Identical genomes
• C. Immune to all human diseases
• D. No similarities to humans

Answer: (A)

Primates are valuable in research because their immune systems and disease responses are closely aligned with humans, making studies of infections, vaccines, and therapies more predictive for people. Their immune cells, signaling pathways, and genetic regulation of immunity operate in ways that resemble human biology, so how diseases progress and how the body responds to treatments tends to mirror human outcomes more closely than in many other animals. They are not genetically identical to humans, and they aren’t immune to all human diseases, but the strong immunological and disease- response similarities provide a much more relevant model for translating findings to human health.
