摘要: Methods for delivering potentially therapeutic or prophylactic protein and peptide agents to mammalian cells are provided. The agents are delivered by mutant trypanosomatid protozoa that have been genetically manipulated to code for such protein or peptide agents. The mutant protozoa additionally lack certain enzymes within the heme biosynthetic pathway, making the mutants susceptible to porphyria and eventual lysis.
