In this study, we performed a novel, comprehensive analysis of the kinetics of expansion of components of the HIV-specific CD8+ T cell response in 21 acutely infected individuals. Epitope-specific T cell responses expanded asynchronously during primary infection in all subjects. The most rapidly expanded responses peaked as early as 5 days following symptomatic presentation and were typically of very limited epitope breadth. Responses of additional specificities expanded and contracted in subsequent waves, resulting in successive shifts in the epitope immunodominance hierarchy over time. Sequence variation and escape were temporally associated with the decline in magnitude of only a subset of T cell responses, suggesting that other factors such as Ag load and T cell exhaustion may play a role in driving the contraction of HIV-specific T cell responses. These observations document the preferential expansion of CD8+ T cells recognizing a subset of epitopes during the viral burst in acute HIV-1 infection and suggest that the nature of the initial, very rapidly expanded T cell response may influence the efficiency with which viral replication is contained in acute\/early HIV infection.<\/jats:p>","DOI":"10.4049\/jimmunol.0803658","type":"journal-article","created":{"date-parts":[[2009,5,19]],"date-time":"2009-05-19T21:00:29Z","timestamp":1242766829000},"page":"7131-7145","source":"Crossref","is-referenced-by-count":89,"title":["Kinetics of Expansion of Epitope-Specific T Cell Responses during Primary HIV-1 Infection"],"prefix":"10.1093","volume":"182","author":[{"given":"Emma L","family":"Turnbull","sequence":"first","affiliation":[{"name":"Viral Immunology Group, Jenner Institute, University of Oxford , Compton,","place":["United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"MaiLee","family":"Wong","sequence":"additional","affiliation":[{"name":"Viral Immunology Group, Jenner Institute, University of Oxford , Compton,","place":["United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuyi","family":"Wang","sequence":"additional","affiliation":[{"name":"Departments of Medicine and Microbiology, University of Alabama , Birmingham, AL 35294"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiping","family":"Wei","sequence":"additional","affiliation":[{"name":"Departments of Medicine and Microbiology, University of Alabama , Birmingham, AL 35294"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicola A","family":"Jones","sequence":"additional","affiliation":[{"name":"Viral Immunology Group, Jenner Institute, University of Oxford , Compton,","place":["United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karen E","family":"Conrod","sequence":"additional","affiliation":[{"name":"Viral Immunology Group, Jenner Institute, University of Oxford , Compton,","place":["United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diana","family":"Aldam","sequence":"additional","affiliation":[{"name":"Centre for Sexual Health and HIV Research, Mortimer Market Centre , London,","place":["United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jo","family":"Turner","sequence":"additional","affiliation":[{"name":"Centre for Sexual Health and HIV Research, Mortimer Market Centre , London,","place":["United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Pellegrino","sequence":"additional","affiliation":[{"name":"Centre for Sexual Health and HIV Research, Mortimer Market Centre , London,","place":["United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brandon F","family":"Keele","sequence":"additional","affiliation":[{"name":"Departments of Medicine and Microbiology, University of Alabama , Birmingham, AL 35294"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ian","family":"Williams","sequence":"additional","affiliation":[{"name":"Centre for Sexual Health and HIV Research, Mortimer Market Centre , London,","place":["United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George M","family":"Shaw","sequence":"additional","affiliation":[{"name":"Departments of Medicine and Microbiology, University of Alabama , Birmingham, AL 35294"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Persephone","family":"Borrow","sequence":"additional","affiliation":[{"name":"Viral Immunology Group, Jenner Institute, University of Oxford , Compton,","place":["United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2009,6,1]]},"reference":[{"key":"2025032715464992000_R1","first-page":"4650","article-title":"Temporal association of cellular immune responses with the initial control of viremia in primary human immunodeficiency virus type 1 syndrome.","volume-title":"J.
