Fusion of the viral envelope, or infected cell membranes with uninfected cell membranes, is an essential step in the viral life cycle. Recent studies involving the human immunodeficiency virus type 1(HIV-1) demonstrated that synthetic peptides (designated DP-107 and DP-178) derived from potential helical regions of the transmembrane (TM) protein, gp41, were potent inhibitors of viral fusion and infection. A computerized antiviral searching technology (C.A.S.T.) that detects related structural motifs (e.g., ALLMOTI 5, 107x178x4, and PLZIP) in other viral proteins was employed to identify similar regions in the Epstein-Barr virus (EBV). Several conserved heptad repeat domains that are predicted to form coiled-coil structures with antiviral activity were identified in the EBV genome. Synthetic peptides of 16 to 39 amino acids derived from these regions were prepared and their antiviral activities assessed in a suitable in vitro screening assay. These peptides proved to be potent inhibitors of EBV fusion. Based upon their structural and functional equivalence to the known HIV-1 inhibitors DP-107 and DP-178, these peptides should provide a novel approach to the development of targeted therapies for the treatment of EBV infections.

The invention relates to a preparation method and application of an autologous CAR (chimeric antigen receptor)-T cell.

A biomedical device assembly, such as a stent, for the targeted treatment of a tissue, such as the inhibition of restentosis. The stent is coated with an antigen, which is an example of a lock. The antigen can be bound by a labelled antibody, which is an example of a key and an effector. The antibody is preferably labelled with a radioactive source. According to one method of preparing the biomedical device assembly, after the stent has been placed in the blood vessel of the subject, the antibody is injected. The antibody then binds to the antigen on the stent, thereby localizing the radioactive source to the area to be treated, for example for restenosis. Other biomedical devices, such as a coil, an artificial valve or a vascular graft, could also be used in the place of the stent. The biomedical device could be placed in another biological passageway, such as the gastrointestinal tract, an airway or the genitourinary tract.
