The first EU-Simia Japan meeting took place at CNRS headquarters in Paris on 27-28 October 2025, gathering over 100 scientists specialising in primate biomedical research. Japanese researchers presented work on immunology, development, neurodegenerative diseases and decision-making mechanisms, while European and North American colleagues shared progress in vaccine therapies and neuro-technologies. 

The 2025 Nobel Prize in Physiology or Medicine was awarded to three researchers — Shimon Sakaguchi, Mary E. Brunkow and Fred Ramsdell — for discovering how the immune system is kept in check, based on studies in mice.

Researchers in Japan have tested a new drug that provides powerful pain relief in mice and monkeys, without the dangers of opioids.  

Research from Japan showed that a combination of two naturally occurring bacteria eliminated tumours in mice, even without the assistance of the immune system.

A Japanese study conducted on fruit flies found that immune cells attacking cancer cells release signals that can actually cause tumours to grow more aggressively.
