In a first aspect, the present invention relates to new recombinant artificial polypeptides allowing cytoplasmic signaling in cells containing the same. In particular, the present invention relates to a system for transmitting signals containing a recombinant polypeptide containing a domain with a first binding partner selected from an artificial ligand and a receptor binding an artificial ligand, a transmembrane domain and a cytoplasmic signaling domain whereby the domain with the binding partner and the cytoplasmic signaling domain are a combination of domains not naturally occurring in an organism and the second binding partner for specific forming of the binding pair. In a further aspect, a nucleic acid molecule comprising a nucleic acid sequence encoding the polypeptide according to the present invention as well as a vector, cell, cell line or host cell containing said vector are provided. In addition, the present invention relates to the use of the recombinant polypeptide according to the present invention in treating cancer or autoimmune disease or allowing immune modulation of a subject as well as for use to change the status of cells when applying the specific second binding partner of the first binding partner present in the recombinant polypeptide according to the present invention.

The present disclosure is related to compositions that include polynucleotides encoding chimeric receptors, methods of delivering polynucleotides encoding chimeric receptors to immune cells, and methods of using immune cells encoding chimeric receptors to treat or prevent cancer.

Provided herein are compositions which exhibit novel therapeutic capabilities and allow to reduce the off-target effect of therapeutic antibodies. The compositions include recombinant proteins that if expressed by a T cell can efficiently recruit therapeutic antibodies to their site of action.

The present disclosure relates to methods of treating a patient with a cancer by administering to the patient a composition comprising CAR T cells and a small molecule linked to a targeting moiety by a linker. The disclosure also relates to compositions for use in such methods.

Provided herein are anti-CD24 antibodies that selectively bind human CD24 expressed in cancer cells, but not human CD24 expressed in non-cancerous cells, and the use of such antibodies in cancer therapy.

The present invention generally relates to diagnostic assays using cell cultures, in particular to chimeric antigen receptor (CAR) expressing reporter cell assays to analyze samples, in particular patient samples, to diagnose cancer by quantifying the expression of tumor antigens and/or predicting clinical response to cancer immunotherapies. A further aspect of the present invention is to improve safety of e.g., cancer immunotherapies.

Provided are methods for activating an antigen-presenting cell and eliciting an immune response by inducing an inducible pattern recognition receptor adapter, or adapter fragment, and CD40 activity. Also provided are nucleic acid compositions comprising sequences coding for chimeric proteins that include an inducible CD40 peptide and an inducible pattern recognition receptor adapter or adapter fragment.

The present disclosure relates to methods of treating a patient with a cancer by administering to the patient a composition comprising CAR T cells and a small molecule linked to a targeting moiety by a linker. The disclosure also relates to compositions for use in such methods.

The present application discloses a composition comprising a MUC1* extra cellular domain peptide attached to a surface and an immune cell that bears a receptor that binds to the peptide.

The present disclosure is related to compositions that include polynucleotides encoding chimeric receptors, methods of delivering polynucleotides encoding chimeric receptors to immune cells, and methods of using immune cells encoding chimeric receptors to treat or prevent cancer.
