- Monoclonal antibodies and antibody fragments are widely used in therapeutics and diagnoses. While mammalian cells serve as the host cells for antibody production, insect cells can produce large quantities of secretory antibodies in serum-free suspension cultures. The effects of lithium on the processes of autophagy and apoptosis in mammalian cells are well chronicled. In the present study, stably transformed insect cells, which produce an engineered antibody molecule, were cultured with lithium chloride in a serum-free medium. Treatment with lithium chloride induced autophagy and apoptosis in recombinant insect cells and led to increases in the yields of secreted antibodies.
