My efforts were inspired by early work showing a retroviral etiology for leukemias in various animals, including non-human primates. My two main approaches were to develop criteria for and methods for detection of viral reverse transcriptase and to identify growth factors that could support the growth of hematopoietic cells. These efforts finally yielded success following the discovery of IL-2 and its use to culture adult T cell lymphoma\/leukemia cells.<\/jats:p>","DOI":"10.1186\/1742-4690-2-17","type":"journal-article","created":{"date-parts":[[2005,3,3]],"date-time":"2005-03-03T07:25:50Z","timestamp":1109834750000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":142,"title":["The discovery of the first human retrovirus: HTLV-1 and HTLV-2"],"prefix":"10.1186","volume":"2","author":[{"given":"Robert C","family":"Gallo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2005,3,2]]},"reference":[{"key":"63_CR1","doi-asserted-by":"crossref","first-page":"5059","DOI":"10.1016\/S0021-9258(18)99476-7","volume":"242","author":"RC Gallo","year":"1967","unstructured":"Gallo RC, Perry S, Breitman TR: The enzymatic mechanisms for deoxythymidine synthesis in human leukocytes.
