The present disclosure relates to chimeric antigen receptors (CARs), which bind to Globo series antigens (e.g. Globo H, SSEA-3 or SSEA-4), including an antigen-binding fragment (Fab) or a single-chain variable fragment (scFv). Further, the present methods are also provided for administering CARs to a subject in an amount effective to inhibit cancer cells.

A method for producing CAR-M1 macrophages expressing a chimeric antigen receptor in vitro and in vivo includes using a conjugate of a non-viral gene delivery system and a chimeric antigen receptor gene. The CAR-M1 macrophages are produced in vivo by delivering genes encoding a chimeric antigen receptor and IFN-?, specifically to macrophages in the body, and thus does not require culturing and preparing an in-vitro cellular therapeutic agent, thus reducing the manufacturing costs of therapeutic agents. The CAR-M1 macrophages are a safer therapy since a non-viral vector is used, as compared to the production of CAR-M1 macrophages by gene delivery using a viral vector, and are a novel therapeutic candidate having the advantage of high anticancer efficiency for solid cancers, due to CAR-M1 macrophages in which intrinsic properties of macrophages infiltrating solid cancers and cancer cell phagocytosis are improved.

The present invention is inter alma concerned with a T cell receptor fusion construct comprising two specific peptidic moieties, one of these two moieties binding to the spike protein from coro-naviruses and binding to ACE2, in particular the spike proteins from SARS-CoV-2 and/or SARS-CoV-1, and one of these moieties being a protein of the T cell receptor complex. A vector comprising the genetic information encoding the T cell receptor fusion construct is also part of the present invention, as well as a process of transfecting or transducing T cells and a modified T cell comprising the T cell receptor fusion construct. Importantly, the present invention also relates to a T cell receptor fusion construct, a vector or a modified T cell for use in the treatment of a disease and in particular for use in the treatment of a disease caused by a coronavirus such as e.g. COVID-19 or SARS.

An inducible chimeric antigen receptor and its application relate to the field of immune therapy. The inducible antigen receptor includes a single-chain variable fragment (scFv) antibody against human CSF1R, a truncated hIgG1 hinge region SH, a T cell co-stimulatory signaling molecule, and a T cell cytoplasmic signaling domain. Transcription of the chimeric antigen receptor is regulated by an inducible expression element tet operator. The induce chimeric antigen receptor molecules can be used to modify T lymphocytes, eliminating the cytokine storm problem of CAR-T cells in the treatment of Alzheimer's disease (AD), and achieving target treatment of AD.
