Oral vaccine produced from transgenic plants

ABSTRACT

An important feature of immune system in general and gastrointestinal immune system in particular is the mobility of member cells. In DNA recombination technique, bacteria like E. coli are often used to make recombination protein including vaccine . The advantage of the bacteria is manipulating easily with their gene. There are two major methods to transfer gene in plants. One is based on Agrobacterium tumefactions, a bacterium that naturally live in the soil, which is able to transfer a number of DNA including one of its plasmids to plant cells to integrate into the plant's genome at cell nucleus. The other is transformation by Agrobacterium which is more common used to make vaccine transgenic plants
