We present a preclinical gene therapy study for Farber disease employing a lentiviral vector (LV-huAC\/huCD25) in three enzymatically normal nonhuman primates. Autologous, mobilized peripheral blood (PB) cells were transduced and infused into fully myelo-ablated recipients with tracking for at least 1 year. Outcomes were assessed by measuring the AC specific activity, ceramide levels, vector persistence\/integration, and safety parameters. We observed no hematological, biochemical, radiological, or pathological abnormalities. Hematological recovery occurred by approximately 3 weeks. Vector persistence was observed in PB and bone marrow (BM) cells by qualitative and quantitative PCR. We did not observe any clonal proliferation of PB and BM cells. Importantly, AC-specific activity was detected above normal levels in PB and BM cells analyzed post-transplantation and in spleens and livers at the endpoint of the study. Decreases of ceramide in PB cells as well as in spleen and liver tissues were seen. We expect that this study will provide a roadmap for implementation of clinical gene therapy protocols targeting hematopoietic cells for Farber disease and other LSDs.<\/jats:p>","DOI":"10.1089\/hum.2010.195","type":"journal-article","created":{"date-parts":[[2011,1,31]],"date-time":"2011-01-31T09:31:00Z","timestamp":1296466260000},"page":"679-687","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":35,"title":["Autologous Transplantation of Lentivector\/Acid Ceramidase\u2013Transduced Hematopoietic Cells in Nonhuman Primates"],"prefix":"10.1177","volume":"22","author":[{"given":"Jagdeep S.","family":"Walia","sequence":"first","affiliation":[{"name":"University Health Network","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anton","family":"Neschadim","sequence":"additional","affiliation":[{"name":"University of Toronto","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Orlay","family":"Lopez-Perez","sequence":"additional","affiliation":[{"name":"University Health Network","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulfatah","family":"Alayoubi","sequence":"additional","affiliation":[{"name":"University of Toronto","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Fan","sequence":"additional","affiliation":[{"name":"University Health Network","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"St\u00e9phane","family":"Carpentier","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Paul Sabatier","place":["France"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melissa","family":"Madden","sequence":"additional","affiliation":[{"name":"University Health Network","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chyan-Jang","family":"Lee","sequence":"additional","affiliation":[{"name":"University Health Network","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fred","family":"Cheung","sequence":"additional","affiliation":[{"name":"Princess Margaret Hospital","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A.","family":"Jaffray","sequence":"additional","affiliation":[{"name":"University Health Network","place":["Canada"]},{"name":"University of Toronto","place":["Canada"]},{"name":"University of Toronto","place":["Canada"]},{"name":"Princess Margaret Hospital","place":["Canada"]},{"name":"University Health Network","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thierry","family":"Levade","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Paul Sabatier","place":["France"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
