      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 ...

      Global genetic variation of HIV-1 infection 

      Anastassopoulou, C. G.; Kostrikis, Leontios G. (2006)
      Variability, both at the population (interhost) as well as at the individual (intrahost) level is a key property of HIV that stems mainly from the inherent infidelity of the reverse transcriptase enzyme that the virus uses ...

      Hepatitis C infection among intravenous drug users attending therapy programs in Cyprus 

      Demetriou, Victoria L.; Van De Vijver, D. A. M. C.; Hezka, Johana; Kostrikis, Leontios G.; Savvopoulou, Natasa; Georgiades, Neoklis; Charilaou, Charis C.; Argyriou, Argyris; Pavlou, Tina; Platritis, Kyriakos; Veresies, Kyriakos L. (2010)
      The most high-risk population for HCV transmission worldwide today are intravenous drug users. HCV genotypes in the general population in Cyprus demonstrate a polyphyletic infection and include subtypes associated with ...

      Molecular epidemiology of hepatitis C infection in cyprus: Evidence of polyphyletic infection 

      Demetriou, Victoria L.; Van De Vijver, D. A. M. C.; Kostrikis, Leontios G.; Chimonides, S.; Evgeniou, N. A.; Hadjigeorgiou-Vounou, E.; Koliou-Mazeri, M.; Papakyriakou, P.; Petsas, L.; Potamitis, G. (2009)
      The genetic diversity of the hepatitis C virus (HCV) in Cyprus is investigated for the first time in this study. Nucleotide sequence analysis of the CORE-E1 and NS5B regions of the HCV genome was performed on blood plasma ...
