Recombinant lactic acid bacteria (LAB), in particular lactococci and lactobacilli, have gained increasing interest as mucosal delivery vehicles in recent years. With the development of mucosal vaccines, studies on LAB expression systems have been mainly focused on the generation of genetic tools for antigen expression in different locations. Recombinant LAB show advantages in a wide range of aspects over other mucosal delivery systems and represent an attractive candidate for the delivery of therapeutic and prophylactic molecules in different applications. Here, we review the recent data on the use of recombinant LAB as mucosal delivery vectors and the associated health benefits, including the prevention and treatment of inflammatory bowel diseases (IBDs), autoimmune disorders, and infections by pathogenic microorganisms from mucosal surfaces. In addition, we discuss the use of LAB as vehicles to deliver DNA directly to eukaryotic cells. Researches from the last 5 years demonstrate that LAB as vectors for mucosal delivery of therapeutic molecules seem to be a realistic therapeutic option both in human and animal diseases.
