Cytotoxic activity of HIV-specific and heterologous CTL clones derived from patient 0407 during primary HIV infection.
(A) CTL activity of T-cell micropopulations derived by limiting dilution was tested against autologous targets infected with a panel of recombinant vaccinia viruses expressing HIV-1 proteins. The significance threshold was set at 10% specific cytolytic activity. (B) DNA sequence of the CDR3 (V[D]J) region of the TCR β chain from the 4 CTL clones shown in A. The sequences used to design clonotype-specific probes are boxed. Nomenclature of TCRBV families is according to Arden et al.31
