Using a recombinant vaccinia virus (VV) that expresses E. coli β galactosidase (β-Gal) lo infect lymphocytes, we show that enzymometrically or immunologically delectable β-Gal expression is less pronounced among T cells than among B cells. VV infection caused growth inhibition of B cells, but barely affected T-cell proliferation in vitro. Moreover, the production of infectious viral particles was less pronounced in T lymphocytes. Kinetic studies revealed that after an initial dose-dependent growth inhibition, T cells continued lo proliferate without the doubling time being affected by VV infection. Nonetheless, the T cells do express proteins encoded by recombinant VV, such as β-Gal. or secrete soluble proteins such as interleukin-4 though at a lower efficiency at the per cell level than B lymphocytes. In conclusion, the physiology of T cells appears to be less perturbed by VV than that of B cells, although the virus is capable of directing expression of recombinant genes to T lymphocytes.
