It’s been a busy few weeks for those who wish to explain the role of primates in research. Last week the NIH held a workshop on “Ensuring the Continued Responsible Oversight of Research with Non-Human Primates” (watch it back here). The Congressionally mandated workshop resulted from report language that was associated with a PETA campaign. PETA hoped the workshop would question whether primates should be used in research at all. Instead PETA were disappointed when many experts came together to talk about how primates remained important to medical and scientific research. Days before the event, PETA activist, Professor John Gluck, wrote to the New York Times to criticise the use of primates in research. Speaking of Research posted a response – “The ethics and value of responsible animal research” – that was signed by over 100 scientists. Other organisations have subsequently written back to the newspaper with letters published this week.
Over in the UK, a group of 21 academics (primarily anthropologists) including Sir David Attenborough (notable broadcaster and naturalist) wrote to the online-only Independent newspaper to call for an end to certain neuroscience experiments involving primates. This provoked a backlash from the research community, who accused him of being “seduced by pseudoscience“. They may have had a point – Attenborough’s letter, organised by Cruelty Free International, backed itself up with a recent paper “Non-human primates in neuroscience research: The case against its scientific necessity” (authored by two staff at Cruelty Free International). The UK Expert Group for Non-Human Primate Neuroscience Research told The Independent:
“We are disappointed to see that David Attenborough and a number of scientists have been misled by the pseudoscience in the paper by CFI, an organisation intent on ending research with all animals, not just primates. “
The paper (by Bailey & Taylor, 2016) itself suggests that several medical advances – such as Deep Brain Stimulation – did not rely on animal studies. This would not seem to match what can be seen in the academic literature, indeed Alim Benabid, who won a Lasker Award for his role in developing the technique noted the important role of animal models, including primates.
There are many other events which have played into a frustration by primate researchers, but the response was huge. Understanding Animal Research coordinated a letter on the role of primates in research. Within a few days hundreds of primate researchers and neuroscientists had signed up. Notable signatories included: Sir John Gurdon, who won the 2012 Nobel Prize in Physiology or Medicine, and the 2009 Albert Lasker Basic Medical Research Award, for their work in reprogramming mature cells into early stem cells; Sir John E Walker, who won the 1997 Nobel Prize in Chemistry for elucidating the mechanisms behind the synthesis of ATP; Professor Mahlon DeLong and Alim Benabid, who jointly won the 2014 Lasker-DeBakey Clinical Medical Research Award for their research developing Deep Brain Stimulation as a surgical treatment for Parkinson’s (the same discovery that the Bailey & Taylor, 2016, paper suggested did not require primates); and Professor Miguel Nicolelis, whose Walk Again project allowed a young paraplegic in an exo-skeleton to kick a football.
Over twenty organisations, including Speaking of Research, the Society for Neuroscience (SFN), and the American Psychological Association (APA) signed their support ( a full list of signatories can be found here). The letter was published by the UK newspaper, The Guardian, on 13th September (and the following day in print), along with an accompanying article.
Furthermore, around 400 researchers also signed on to the letter:
Nonhuman primates have long played a key role in life-changing medical advances. A recent white paper by nine scientific societies in the US produced a list of fifty medical advances from the last fifty years made possible through studies on nonhuman primates. These included: treatments for leprosy, HIV and Parkinson’s; the MMR and hepatitis B vaccines; and earlier diagnosis and better treatment for polycystic ovary syndrome and breast cancer.
The biological similarities between humans and other primates means that they are sometimes the only effective model for complex neurodegenerative diseases such as Parkinson’s. More than ten million people suffer from Parkinson’s worldwide, and a recent study estimated that one in three people born in 2015 will develop dementia in their lifetime. Primate research offers treatments, and hope for future treatments, to patients and their families. Already over two hundred thousand Parkinson’s patients have had their life dramatically improved thanks to Deep Brain Stimulation surgery, which reduces the tremors of sufferers. This treatment was developed from research carried out in a few hundred monkeys in the 1980-90s.
Given that primates are intelligent and sensitive animals, such research requires a higher level of ethical justification. The scientific community continues to work together to minimise the suffering of primates wherever possible. We welcome the worldwide effort to Replace, Refine and Reduce the use of primates in research.
We, the undersigned, believe that if we are to effectively combat the scourge of neurodegenerative and other crippling diseases, we will require the careful and considered use of nonhuman primates. Stringent regulations across the developed world exist to ensure that primates are only used where there is no other available model – be that the use of a mouse or a non-animal alternative and to protect the wellbeing of those animals still required. The use of primates is not undertaken lightly, however, while not all primate research results in a new treatment, it nonetheless plays a role in developing both the basic and applied knowledge that is crucial for medical advances.

While, the letter itself is published. Understanding Animal Research are continuing the accept signatories from neuroscientists and primate researchers (signatories must be from academia and must hold a PhD, MD or equivalent). These are being updated on a regular basis on their website.

Already they are up to over 550 signatories – just one week after they started collecting (considerably more than the 21 signatories that Cruelty Free International managed in their letter, and with a lot more expertise in the area of Neuroscience).
