Assessment of Carrot Callus as Biofactories of an Atherosclerosis Oral Vaccine Prototype.

Atherosclerosis is a pathology leading to cardiovascular diseases with high epidemiologic impact; thus, new therapies are required to fight this global health issue. Immunotherapy is a feasible approach to treat atherosclerosis and given that genetically engineered plants are attractive hosts for vaccine development; we previously proved that the plant cell is able to synthesize a chimeric protein called CTB:p210:CETPe, which is composed of the cholera toxin B subunit (CTB) as immunogenic carrier and target epitopes from the cholesteryl ester transfer protein (CETP) and apolipoprotein B100 (p210). Since CTB:p210:CETPe was expressed in tobacco at sufficient levels to evoke humoral responses in mice, its expression in carrot was explored in the present study looking to develop a vaccine in a safe host amenable for oral delivery; avoiding the purification requirement.

Carrot cells: a pioneering platform for biopharmaceuticals production.

Carrot (Daucus carota L.) is of importance in the molecular farming field as it constitutes the first plant species approved to produce biopharmaceuticals for human use. In this review, features that make carrot an advantageous species in the molecular farming field are analyzed and a description of the developments achieved with this crop thus far is presented.
