In vivo production and systemic delivery of therapeutic antibodies by engineered cells might advantageously replace injection of purified antibodies for treating a variety of life-threatening diseases, including cancer, acquired immunodeficiency syndrome, and autoimmune diseases. We report here that skin fibroblasts retrovirally transduced to express immunoglobulin genes can be used for sustained long-term systemic delivery of cloned antibodies in immunocompetent mice. Importantly, no anti- idiotypic response against the ectopically expressed model antibody used in this study was observed. This supports the notion that skin fibroblasts can potentially be used in antibody-based gene/cell therapy protocols without inducing any adverse immune response in treated individuals.
