The present invention refers to cells from a subpopulation of progenitors of endothelial cells loaded with gold nanoparticles sensitive to excitation with infrared radiation with consequent release of thermal energy, to a composition having a plurality of these cells and to their use in the diagnosis and treatment of solid tumours thanks to the selective localization of the composition in the tumour mass, which can be thus identified easily for diagnostic purposes by marking the cells with appropriate marking agents, or treated by stimulation with pulsed laser beam up to the complete cauterization of the tumour mass for a targeted and highly effective therapeutic action.

A target tissue can be treated with a radioisotope. Some methods for treating a target tissue with a radioisotope include determining a distance between a target tissue and a surface of a matrix material to be positioned adjacent the target tissue and, based on the determined distance, determining an activity to be mixed with the matrix material to obtain a desired activity concentration. Some methods further include mixing the radioisotope with the matrix material. In some embodiments, the matrix material comprises bone cement, and the target tissue is a tumor in a bone. The radioisotope may be a beta-emitting radioisotope mixed in the cement at a concentration to form a radioactive cement.

The application describes a T-cell expressing a chimeric antigen receptor (CAR T-cell) containing superparamagnetic iron-based particles (loaded CAR T-cell) for use in treating a tumor. Said loaded CAR T-cell exhibits a reduced cytokine release upon binding to a cell of the tumor expressing an antigen being recognized by the CAR of the CAR T-cell, compared to a CAR T-cell not containing superparamagnetic iron-based particles (unloaded CAR T-cell) under the same conditions. Furthermore, an in vitro method of generating a CAR T-cell containing superparamagnetic iron-based particles is described, whereby such loaded CAR T-cells are generated.

Disclosed herein are methods of detecting tumors, monitoring cancer therapy, and selectively inhibiting the proliferation and/or killing of cancer cells utilizing a papilloma pseudovirus or a papilloma virus-like particle (VLP).

The present invention relates to myeloid derived suppressor cells (MDSCs) and using these cells in conjunction with nuclear medicine imaging methods to image cancer tumors. The MDSC cells are separated from blood and either radiolabeled with nuclear medicine agents or pretargeting agents and reinjected in patient. The cells preferentially concentrate in tumors allowing imaging of cancer tumors. The imaging technique can be used to image tumors for diagnosis and/or assessment of treatment response for cancer patients undergoing cancer treatments.

The present invention concerns a positron emission tomography (PET) contrast agent or imaging tracer comprising a red blood cell (RBC) internally labeled with 2-deoxy-2-(.sup.18F)fluoro-D-glucose (FDG); a method of preparing RBCs of a human or non-human animal for PET, comprising labeling RBCs in vitro with FDG to produce FDG-labeled RBCs; a method for in vivo imaging of RBCs using PET, comprising: introducing RBCs internally labeled with FDG (FDG-RBCs) into the circulatory system of a human or non-human animal subject in vivo; and PET imaging the introduced FDG-RBCs in the subject; a composition useful for labeling RBCs, and a kit for labeling RBCs.

A method for labeling exosomes with a radioactive substance using an amine group on surfaces of the exosomes includes providing a cell-derived exosome, treating a surface of the exosome with N-hydroxysuccinimide-azadibenzocyclooctyne (NHS-ADIBO), and mixing the treated exosome with N3-introduced chelator-radioactive substance to conduct a reaction between the chelator and an amine group present on the surface of the exosome, wherein the radioactive substance is introduced inside the exosome by the above reaction. The exosomes can be stably labeled at high labeling efficiency, and the exosomes can be favorably used as an agent for nuclear medicine imaging and therapeutic imaging for confirming the biological distribution of exosomes and whether the exosomes move to target organs and target diseases in animals including a human being.

Provided herein is the two component self-assembly single wall nanotube system and the single wall nanotube construct that is the second component. The two component self-assembly single wall nanotube system has a morpholino oligonucleotide with a targeting moiety followed by a single wall nanotube construct with second morpholino oligonucleotides complementary to the first morpholino oligonucleotides and one or both of a therapeutic or diagnostic payload molecule linked to the single wall nanotube construct

The present invention is directed generally to eukaryotic cells comprising single-celled organisms that are introduced into the eukaryotic cell through human intervention and which transfer to daughter cells of the eukaryotic cell through at least five cell divisions, and methods of introducing such single-celled organisms into eukaryotic cells. The invention also provides methods of using such eukaryotic cells. The invention further provides single-celled organisms that introduce a phenotype to eukaryotic cells that is maintained in daughter cells. The invention additionally provides eukaryotic cells containing magnetotactic bacteria.
