Chromium release assays from the lymphoid organs of patients C, R, and K.

Results from the bulk SMCs or TMCs and from one white pulp (WP) or germinal center (GC) of the 24 tested for each patient are shown. Partially compatible B-lymphoblastoid cell lines were infected with wild-type vaccinia (wt; ○) or recombinant vaccinia viruses expressing gag, pol, and env (●) and used as targets. The HLA molecules shared between patient and target cells are shown in Table 1.
