 AB    Drugs that reduce viral production or prevent viral spread by
       interference with the host's cellular components are unlikely to induce
       resistance, in contrast to treatment modalities that interact with the
       HIV-1 life cycle. Two features make L-cycloserine (L-CS) a candidate
       drug of this kind: (a) L-CS is a potent inhibitor of the sphingolipid
       pathway (b) sphingolipids, galactocerebrosides, and sulfatides have been
       shown, by others, to bind gp120. In a feasibility and efficacy study, we
       have found that L-CS inhibits HIV-1 replication in a CD4+ lymphoid cell
       line (CEM) as documented by the reduction of syncytium formation, the
       number of HIV-1 infected cells, and p24 protein production. This
       observation may lead to a new strategy for the treatment of HIV-1
       infection.
