The Oregon National Primate Research Center (ONPRC) is at the forefront of providing hope for patients who face life-threatening conditions.

Take Batten disease, a fatal neurodegenerative disorder for which there is no cure. In 2018, researchers at the ONPRC identified a naturally occurring mutation in Japanese macaques that mimics Batten disease in people; this specific species of macaque is the only known nonhuman primate model in which the condition occurs naturally. The ONPRC team’s long-term stewardship and care of this unique research species continue to provide hope for curing a terminal disorder.

Similarly, recent news about the development of the first personalized gene therapy for “Baby KJ” catalyzed a new treatment pathway toward individualized therapies for rare diseases. The integrative research approach included new approach methodologies (NAMs) and studies in long-tailed macaques (LTMs) to assess safety before treatment (Musunuru et al., 2025).

Both examples emphasize the continuing need for research with animals.

If the United States is serious about making our country healthy, we must protect the full research ecosystem that makes discovering causes, preventions, treatments and cures possible. That structure includes NAMs and research with NHPs when no other scientific models are appropriate. Anything less stands to jeopardize scientific rigor, safety and validity, stall movement toward future breakthroughs and even stop work that holds the promise of improved health for our nation and world.
