    • The invention relates to a protein complex for the delivery of an antigen to and across mucosal surfaces and the production of said complex in a host cell, such as a plant. Provided is a protein complex comprising at least two, preferably identical, subunits wherein at least one subunit is unaltered and at least one subunit is fused to a first molecule of interest and wherein the protein complex is able to interact with a cell surface receptor via said subunits. Also provided is a method for producing a protein complex according to the invention, comprising a) providing a host cell with a nucleotide sequence encoding an unaltered subunit and a nucleotide sequence encoding a molecule of interest, wherein at least one molecule of interest is fused to a subunit; b) culturing said host cell thereby allowing expression of said nucleotide sequences and allowing for assembly of the protein complex; c) isolating the complex; d) determining the binding of the complex to a cell surface receptor or to a molecule which mimics a cell surface receptor
    • 本发明涉及用于将抗原递送至粘膜表面并跨过粘膜表面并在宿主细胞如植物中产生所述复合物的蛋白质复合物。 提供了包含至少两个,优选相同的亚基的蛋白质复合物,其中至少一个亚基是未改变的,并且至少一个亚基与第一目的分子融合,并且其中所述蛋白质复合物能够通过所述蛋白质复合体与细胞表面受体相互作用 亚单位。 还提供了一种用于生产根据本发明的蛋白质复合物的方法,包括:a)向宿主细胞提供编码未改变亚基的核苷酸序列和编码目的分子的核苷酸序列,其中至少一个目的分子融合到 一个亚单位 b)培养所述宿主细胞,从而允许表达所述核苷酸序列并允许蛋白质复合物的装配; c)分离复合物; d)确定复合物与细胞表面受体或模拟细胞表面受体的分子的结合
