Complex of a protein comprising zinc oxide-binding peptides and zinc oxide nanoparticles, and use thereof

The present invention relates to a complex of a protein comprising zinc oxide-binding peptides and zinc oxide nanoparticles, to the use thereof as a drug delivery carrier for manufacturing medicines, and to a vaccine composition and a contrast agent comprising the composite. The protein comprising zinc oxide-binding peptides significantly improves the in vivo availability of zinc oxide-binding peptides, and therefore the complex of the present invention can be used not only as a drug delivery carrier for in vivo drug delivery or intracellular drug delivery, but also for in vivo imaging or cell imaging. The complex can be used for producing separating agents for effectively separating biological materials, therapeutic agents for hyperthermia, etc., contrast agents for MRI, and beads applicable to biosensors.

AUGMENTATION OF PERSONALIZED TUMOR SPECIFIC ADAPTIVE IMMUNITY THROUGH EXTRACORPOREAL REMOVAL OF IMMUNE BLOCKING FACTORS
20220040088 · 2022-02-10 · ·

Disclosed are means, methods and compositions of matter useful for amplification of adaptive immune responses towards neoplastic tissue. In one embodiment, immunization of a patient is performed by a means comprising of administering either an exogenous vaccine or stimulation of immunogenicity of the tumor so as to cause release of antigens/increased exposure of antigens, thus resulting in an “endogenous” vaccine. Subsequent to vaccination a patient is treated by an immunopheresis procedure, in order to allow for removal of “blocking factors” produced by the tumor or produced by cells programmed by tumors to produce said blocking factors. In one embodiment further immunization is performed subsequent to removal of said blocking factors in order to allow for enhancement of adaptive immune responses
