Aziz has said that his future research interests will focus on viral, gene, and stem cell therapy to treat Parkinson's and similar movement disorders.

 to conduct a systemic review into Aziz’s research. Macleod accidentally sent an email intended for a colleague to animal rights group. The e-mail stated he felt that Deep Brain Stimulation was an “area of weakness often trumpeted as a success, but which in reality is probably a failure”. He asked for “advice” and suggested he would "avoid, play a straight bat or price [himself] out of the market” for the review requested.

Animal Aid said about the e-mail “He [Dr Macleod] feared that an objective investigation of the associated animal research would expose the treatment's shortcomings. He was determined to avoid being drawn into the front line of the vivisection debate.”

Dr Macleod claimed that he stood by his choice not to do the review “I was not comfortable taking part in a study which was motivated by a desire to undermine Aziz.”

Britain has "probably the most violent and absurd animal rights movement in the world", he told The Guardian.

Defence of cosmetics testing

In an interview published on March 4, 2005, Aziz condoned testing cosmetics on animals, a practice banned in the UK since 1998 and due to be banned across the European Union

 by 2009. He said that to argue cosmetics testing is wrong is "a very strange argument," and that "[p]eople talk about cosmetics being the ultimate evil. But beautifying oneself has been going on since we were cavemen. If it's proven to reduce suffering through animal tests, it's not wrong to use them. To say cosmetics is an absolute evil is absurd."

Other scientists who use animals in research have "distanced themselves" from Aziz's remarks. Clive Page, a researcher at the University of London, said: "I don't think we can justify using animals for cosmetics research. [Prof Aziz], like myself and a few others who talk out about this have worked very hard to try and explain to the public why we do medical research on animals and why it's still necessary. To muddy the waters by bringing back an issue of using animals for something that's not actually approved in the UK is perhaps unfortunate."

There's no movement from the scientific community or the cosmetics industry to have it brought back in. I can't see it being particularly relevant apart from being his personal view."

Felix

An animal rights campaign has formed around a seven-year-old macaque monkey that Aziz has used in his research. Named Felix by Aziz himself, he is one of 100 purpose-bred monkeys used in animal experiments by Oxford University. Felix was featured in a November 2006 BBC documentary about Aziz's work, "Monkeys, Rats and Me." The monkey was shown being "shaped," that is, being encouraged to perform certain tasks by having food and water withheld, in advance of having the symptoms of Parkinson's disease

 on the Parkinsonian symptoms and on his ability to perform the tasks. He will be destroyed at the end of the experiment, which could continue for several years.

Since the BBC documentary aired, SPEAK, a British animal rights campaign formed in 2002, has focused on the "Fight for Felix" as a symbol of their efforts to halt the construction of a new £20 million animal-testing facility in South Park Road, Oxford.
