Interaction of human lymphocytes and viruses in vitro.
Interaction between phytohaemagglutinin (PHA) stimulated human lymphocytes and two DNA viruses (adenovirus type 5 and herpes simplex virus type 1) considered to be closely connected with lymphoid tissues has been studied. The fate of the same viruses was investigated also in non-stimulated separated lymphocytes for comparative purposes. To elicit this interaction infectivity titrations, immunofluorescent technique and electron microscopy were used. The production of viral antigens was investigated by complement fixation. It has been shown that in PHA-stimulated lymphocytes from peripheral blood of healthy donors adenovirus type 5 is capable to replicate in its infectious form. Prolongation of the interval between stimulation and infection of cells significantly influenced the dynamics of replication. Non-stimulated lymphocytes produced antigens but no infectious particles.
