Accordingly, dysfunctional axonal transport is linked to many nervous system conditions. Therefore, being able to image and quantify this dynamic process in live neurons of animal disease models is beneficial for understanding neuropathology and testing new therapies at the preclinical level. As such, intravital approaches have been developed to assess cargo movement in the hindlimb sciatic nerves of live, anaesthetised mice. Here, we describe an adapted method for in vivo imaging of axonal transport in intact median and ulnar nerves of the rodent forelimb. Injection of a fluorescently labelled and non-toxic fragment of tetanus neurotoxin (HCT) into the mouse forepaw permits the identification of signalling endosomes in intact axons of median and ulnar nerves. Through immunofluorescent analysis of forelimb lumbrical muscles and median\/ulnar nerves, we confirmed that HCT is taken up at motor nerve terminals and predominantly locates to motor axons. We then showed that the baseline trafficking of signalling endosomes is similar between the median\/ulnar nerves and the sciatic nerve in adult wild-type mice. Importantly, this adapted method can be readily tailored for assessment of additional cargoes, such as mitochondria. By measuring transport in forelimb and hindlimb nerves, comparative anatomical and functional analyses can be performed in rodent disease models to aid our understanding of peripheral nerve disease pathogenesis and response to injury.<\/jats:p>","DOI":"10.1042\/ns20220098","type":"journal-article","created":{"date-parts":[[2023,1,6]],"date-time":"2023-01-06T10:00:58Z","timestamp":1672999258000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["<i>In vivo<\/i> imaging of axonal transport in peripheral nerves of rodent forelimbs"],"prefix":"10.1042","volume":"7","author":[{"given":"Qiuhan","family":"Lang","sequence":"first","affiliation":[{"name":"1Department of Neuromuscular Diseases and UCL Queen Square Motor Neuron Disease Centre, Queen Square Institute of Neurology, University College London, London WC1N 3BG, U.K."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giampietro","family":"Schiavo","sequence":"additional","affiliation":[{"name":"1Department of Neuromuscular Diseases and UCL Queen Square Motor Neuron Disease Centre, Queen Square Institute of Neurology, University College London, London WC1N 3BG, U.K."},{"name":"2UK Dementia Research Institute, University College London, London WC1E 6BT, U.K."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3782-9045","authenticated-orcid":false,"given":"James\u00a0N.","family":"Sleigh","sequence":"additional","affiliation":[{"name":"1Department of Neuromuscular Diseases and UCL Queen Square Motor Neuron Disease Centre, Queen Square Institute of Neurology, University College London, London WC1N 3BG, U.K."},{"name":"2UK Dementia Research Institute, University College London, London WC1E 6BT, U.K."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","published-online":{"date-parts":[[2023,1,19]]},"reference":[{"key":"2023012316104823100_B1","doi-asserted-by":"publisher","first-page":"292","DOI":"10.1016\/j.neuron.2014.10.019","article-title":"Axonal transport: cargo-specific mechanisms of motility and regulation","volume":"84","author":"Maday","year":"2014","journal-title":"Neuron"},{"key":"2023012316104823100_B2","doi-asserted-by":"publisher","first-page":"161","DOI":"10.1038\/nrn3380","article-title":"Axonal transport deficits and neurodegenerative diseases","volume":"14","author":"Millecamps","year":"2013","journal-title":"Nat.
