      Changes in T Cell Receptor Excision DNA Circle (TREC) Levels in HIV Type 1-Infected Subjects Pre- and Post-Highly Active Antiretroviral Therapy 

      Touloumi, G.; Pantazis, N.; Karafoulidou, A.; Mandalaki, T.; Goedert, J. J.; Kostrikis, Leontios G.; Hatzakis, Angelos E. (2004)
      The T cell receptor excision DNA circle (TREC) level is an independent predictor of HIV-1 disease prognosis. We studied the temporal changes in TREC levels prior to and after highly active antiretroviral therapy (HAART) ...

      Effect of recent thymic emigrants on progression of HIV-1 disease 

      Hatzakis, Angelos E.; Touloumi, G.; Karanicolas, R.; Karafoulidou, A.; Mandalaki, T.; Anastassopoulou, C. G.; Zhang, L.; Goedert, J. J.; Ho, David D.; Kostrikis, Leontios G. (2000)
      Background. The concentration of T-cell receptor-rearrangement excision DNA circles (TREC) in peripheral-blood T cells is a marker of recent thymic emigrant αβ T cells. We studied the predictive ability of measurements of ...

(2014)
      Background: In Europe, a continuous programme (SPREAD) has been in place for ten years to study transmission of drug resistant HIV. We analysed time trends of transmitted drug resistance mutations (TDRM) in relation to the ...

      Quantitation of human immunodeficiency virus type 1 DNA forms with the second template switch in peripheral blood cells predicts disease progression independently of plasma RNA load 

      Kostrikis, Leontios G.; Touloumi, G.; Karanicolas, R.; Pantazis, N.; Anastassopoulou, C. G.; Karafoulidou, A.; Goedert, J. J.; Hatzakis, Angelos E. (2002)
      There are several forms of human immunodeficiency virus type 1 (HIV-1) DNA in peripheral blood T cells and lymph nodes in untreated HIV-1-infected individuals and in patients whose plasma HIV-1 RNA levels are suppressed ...

      T cell receptor excision circles and HIV-1 2-LTR episomal DNA to predict AIDS in patients not receiving effective therapy 

      Goedert, J. J.; O'Brien, T. R.; Hatzakis, Angelos E.; Kostrikis, Leontios G. (2001)
      Objective: To determine whether improved prediction of AIDS-free survival following HIV-1 seroconversion is achieved by measuring HIV-1 2-LTR episomal DNA (2-LTR) circles and T cell receptor rearrangement excision circles ...
