The present invention relates to a monoclonal mouse antibody produced by the hybridoma cell deposited under ICLC accession number ICLC PD n? 16001. Furthermore, the invention relates to an antibody comprising a heavy chain variable region comprising complementarity determining regions CDRH1, CDRH2 and CDRH3, and a light chain variable region comprising complementarity determining regions CDRL1, CDRL2 and CDRL3, wherein CDRH1, CDRH2, CDRH3, CDRL1, CDRL2, and CDRL3 comprise the amino acid sequences GFTFSSFGMH (SEQ ID NO: 1), YISSGSGNFYYVDTVKG (SEQ ID NO: 43), STYYHGSRGAMDY (SEQ ID NO: 3), SASSSVSSMYWY (SEQ ID NO: 4), DTSKMAS (SEQ ID NO: 5), and QQWSSYPPIT (SEQ ID NO: 6), respectively. In addition, the invention relates to antibodies recognizing the same epitope.

The present invention relates to a novel chimeric antigen receptor comprising a CD99 region which participates in immune synapse stabilization as a backbone of the chimeric antigen receptor, an immune cell comprising the same, and the uses thereof. CD99-based CAR-T cells are capable of forming very stable immune synapses with tumor cells compared to conventional backbone-based CAR-T cells and can exhibit improved tumor therapeutic efficiency, so they can be useful for immune cell therapy for the treatment of cancer.

Provided herein are tumor-antigen VCX/Y specific peptides and engineered VCX/Y specific T cell receptors. Also provided herein are methods of generating VCX/Y-specific immune cells and their use for the treatment of cancer. In addition, the VCX/Y-specific peptides may be used as a vaccine.

The disclosure provides a chimeric antigen receptor (CAR) polypeptide having an antigen binding domain comprising an extracellular lectin which specifically binds to glycoproteins expressed on the surface of target cells. Also provided herein are engineered lymphocytes expressing the CAR polypeptide, a nucleic acid molecule encoding the CAR polypeptide, and methods of treating cancer.

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 invention provides compositions and methods for administering a therapeutic agent to a patient, such as pharmaceutical compositions containing a blood product and a therapeutic agent selected from an anthracycline anti-cancer agent (e.g., doxorubicin), a topoisomerase inhibitor, an oxazaphosphinanyl anti-cancer agent, a nitro-aryl anti-cancer agent, a thiol-reactive functional-group agent, a nitric oxide modulator, a platinum-based antineoplastic compound, acrylamide, acrylonitrile, bis(4-fluorobenzyl)trisulfide, a cardiac glycoside, an anti-mitotic agent (e.g., paclitaxel), a nucleoside analog, an EGFR inhibitor, or an anti-microbial agent.

The present invention provides an epitope peptide of a RAS G13D mutant, an antigen presenting cell expressing the epitope peptide, a tumor vaccine containing the antigen presenting cell, and a use of the tumor vaccine in the prevention or treatment of a tumor having RAS G13D mutation. The present invention also provides a T cell receptor (TCR) specifically recognizing a RAS G13D mutant, a conjugate and a fusion protein containing the TCR, an immune cell expressing the TCR, a T cell drug containing the immune cell, and a use of the T cell drug in the prevention or treatment of a tumor having RAS G13D mutation.

The present disclosure provides compositions and methods for the delivery of immune cells to treat un-resectable or non-resected tumor cells and tumor relapse. The compositions comprise (i) a structure comprising an injectable polymer or scaffold comprising pores; (ii) lymphocytes disposed within the structure, (iii) at least one lymphocyte-adhesion moiety associated with the structure; and (iv) at least one lymphocyte-activating moiety associated with the structure, and optionally an immune stimulant.

Provided herein are methods for generating TILs that can then be employed in the treatment of patients having a cancer (e.g., a pediatric cancer, a uveal melanoma or mesothelioma).
