Abstract: Dear Professor Persson, The article published recently by Max Bennett in your journal is a misleading account of a well-documented history of the discovery of non-adrenergic, non-cholinergic nerves and of purinergic signalling (see Burnstock 2006, 2007, 2012a,b). One review was published in Acta Physiologica together with Bertil Fredholm, Alan North and Alex Verkhratsky (Burnstock et al. 2010). The first paper to describe non-adrenergic, non-cholinergic neurotransmission to the guinea-pig taenia coli was a team effort under my direction, where Max Bennett was involved together with Graeme Campbell and Mollie Holman (Burnstock et al. 1964). The first paper suggesting that ATP was a neurotransmitter in non-adrenergic, non-cholinergic nerves was Burnstock et al. 1970, where Max Bennett was not involved. In his article, Bennett states ‘I was employed by Burnstock to establish a technique for recording from excitable cells, called the sucrose gap’ and ‘this did not take long’. This technique was developed 3 years earlier, when I was a postdoc at the National Institute of Medical Research in the UK (Burnstock & Straub 1958). I was subsequently invited by Edith Bülbring in the Dept of Pharmacology, Oxford, to study the electrophysiology of the guinea-pig taenia coli with the sucrose gap technique. Bennett should perhaps have also considered quoting Burnstock (1972) for the initial hypothesis and Webb et al. (1993) where we described the cloning and characterisation of the first P2Y G-protein-coupled receptor (P2Y1). The author of the article published recently in Acta Physiologica, Max Bennett, was employed by me as a part-time electronic technician, while completing a degree in Engineering in 1961 when the discovery of non-adrenergic, non-cholinergic transmission was made. Later, when I recognised that Max Bennett was a highly intelligent and promising scientist, I was allowed at that time to enrol him for an MSc, although he was without any formal training in biology, and subsequently for a PhD, both under my personal supervision.
