  In vivo programming of endogenous antibodies via oral administration of adaptor ligands

  摘要：

  Vaccination is a reliable method of prophylaxis and a crucial measure for public health. However, the majority of vaccines cannot be administered orally due to their degradation in the harsh gut environment or inability to cross the GI tract. In this study, we report the first proof-of-concept study of orally producible chemically programmed antibodies via specific conjugation of adaptor ligands to endogenous antibodies, in vivo. Pre-immuniztion with 2,4-dinitrophenyl (DNP), or the reactive hapten, 1,3-diketone (DK), or a novel reactive hapten, vinyl sulfone (VS) in mice, followed by oral administration of adaptor ligands composed of the hapten and biotin to the pre-immunized mice resulted in successful in vivo formation of the biotin-hapten-antibody complexes within 2 h. Pharmacokinetic evaluations revealed that apparent serum concentrations of programmed antibodies were up to 144 nM and that the serum half-lives reached up to 34.4 h. These findings show promise for the future development of orally bioavailable drug-hapten-antibody complexes as a strategy to quickly and easily modulate immune targets for aggressive pathogens as well as cancer.

  (EN) The invention provides new compositions and methods for qualitative and quantitative immunoassay employing cyclodextrin (CD), labels. The labels comprise a CD ''host'' molecule that includes a fluorescent or chemiluminescent ''guest'' molecule, with a ''coupling group'' available on the CD. The labels are used for labeling various substances such as ligands, antigens, and antibodies, to provided tracers for use in immunoassays and other ligand binding assays. Methods are disclosed for competitive, and noncompetitive ''sandwich'' type assays, as well as heterogeneous and homogeneous assays. The invention provides the following properties and advantages: 1) safer, nonradioactive tracers; 2) potentially higher signal efficiency and longer shelf life; 3) coupling groups for one-step labeling; 4) chemiluminescent detection for more sensitivity; 5) multiple CD labels for efficient labeling; 6) chemical/physical similarity for easier synthesis and use; 7) different colored labels with similar properties; 8) methods are readily automated for high volume applications. The invention also provides catalytic CD labels and methods.(FR) De nouvelles compositions et de nouvelles méthodes permettent de procéder à des essais immunitiares avec des marqueurs en cyclodextrine (CD). Les marqueurs comprennent une molécule ''hôte'' de CD qui contient une molécule ''invitée'' fluorescente ou chimioluminescente, avec un ''groupe de couplage'' agencé sur la CD. Les marqueurs sont utiles pour marquer diverses substances, telles que ligands, antigènes et anticorps, qui servent d'indicateurs lors d'essais immunitaires et d'autres essais par liaison avec des ligands. On décrit des procédés d'essais de type compétitif et non compétitif en ''sandwich'', ainsi que des essais hétérogènes et homogènes. Les propriétés et les avantages de l'invention sont: 1) indicateurs sûrs non radioactifs; 2) des signaux d'une efficacité potentiellement supérieure et une plus longue durée de conservation; 3) des groupes de couplage pour des marquages en une seule étape; 4) une détection chimioluminescente plus sensible; 5) des marqueurs multiples en CD qui assurent un marquage efficace; 6) similarité chimique/physique, qui facilite la synthèse et l'utilisation; 7) des marqueurs de couleurs différentes avec des propriétés similaires; 8) des procédés faciles à automatiser, pour des applications à des volumes importants. L'invention concerne également des procédés et des marqueurs en CD par catalyse.
