“…Also, plants have suitable post-translational machinery similar like mammalian-systems, and the recombinant protein folding in the endoplasmic reticulum (ER) were reported in earlier studies [ 7 , [10] , [11] , [12] , [13] , [14] ]. The plant-produced antigens can also be developed as vaccine candidates [15] , [16] , [17] , [18] , [19] , [20] , [21] . The vaccine candidates, monoclonal antibodies and other non-pharmaceutical proteins (industrial enzymes, growth factors, cytokines, anti-microbial peptides) produced in plants were summarized in recent reviews [ 7 , 22 , 23 ].…”
