2. R= SH syntheses of which were reported by Robins and coworker~~% over 10 years before their immunostimulatory properties were discovered. These low molecular weight nucleosides have been shown to act as intracellular mitogens in murine splenic B lymphocytes4 and appear to be relatively T-cell-independent activators of a subset of human B cells committed to the expression of IgM, IgG, or IgA i~ otypes.~ In addition, these ...
