[Antiviral properties of recombinant human lymphotoxin].

Study of the antiviral properties of recombinant human lymphotoxin obtained from Escherichia coli SG20050/pLT21 strain by microbiological synthesis showed this lymphotoxin to inhibit vesicular stomatitis virus on M-19 cells and exert a synergistic effect with recombinant human gamma-interferon. The drug exhibited no anti-HIV1 activity in experiments with MT4 cells pretreated with the virus or the drug itself; on the contrary, HIV1 reproduction in these cells was enhanced at low concentrations of the recombinant lymphotoxin.
