Abstract: The present invention concerns the development of vesicles that could be used for generation of vaccines or as compound delivery vehicles.

Abstract: The invention is based on a platform for vaccination and/or antibody generation. The invention is based on the display of small molecular immunogenic compounds on the coat of variant surface glycoproteins (VSG) on trypanosomes which results in a highly effective immune response when used as a vaccine or in immunization for antibody production. The herein disclosed antigenic particles are applicable for producing antibodies or can be directly used as vaccines for the treatment of various medical conditions. Most preferably the invention relates to the VSG based vaccines specific for dependency causing substances for the treatment of addiction or avoidance of adverse events during drug abuse. Other applications include methods and uses involving the disclosed compounds and compositions for a treatment or prevention of cancer, infectious disease, contagious neurodegenerative diseases, non-communicable disorders (e.g.

Abstract: The present invention concerns the field of antibodies. More specifically, it relates to an antibody which specifically binds to a hapten being fentanyl or a derivative thereof, said antibody binding to the hapten with an equilibrium dissociation constant (Kd) of at most 1.000 pM, at most 800 pM, at most 600 pM, at most 400 pM, at most 200 pM, at most 100 pM or at most 75 pM, wherein the binding pocket for the hapten comprises amino acids from all three complementary determining regions (CDRs) of each chain. The present invention also relates to a polynucleotide encoding said antibody, a vector or expression construct comprising the polynucleotide, a host cell comprising the polynucleotide or the vector or expression construct or a non-human transgenic organism comprising said polynucleotide or said vector or expression construct.
