The present invention relates to methods for administering therapeutic doses of bispecific T-cell engaging molecules for the treatment of cancer in a patient. The administration methods reduce the incidence and/or severity of adverse events, such as cytokine release syndrome, and entail administering to a patient a priming dose of the bispecific T-cell engaging molecule by continuous intravenous infusion over a period of days followed by administration of a therapeutic dose of the bispecific T-cell engaging molecule by a bolus intravenous infusion at dosing intervals of at least a week.

The disclosure is directed to methods and compositions relating to genetically engineered cells expressing chimeric antigen receptors, where the cells are mobilized lymphocytes.

Provided herein is a method of treating a subject who has multiple myeloma. A single infusion of chimeric antigen receptor (CAR)-T cells comprising an anti-BCMA CAR comprising a polypeptide is administered to the subject. In certain embodiments, the dose of CAR-T cells administered to the subject is from 1.010.sup.5 to 5.010.sup.6 of CAR-T cells per kilogram of the subject's mass. The method of treatment is effective in obtaining and maintaining minimal residual disease negativity status, as well as other beneficial clinical outcomes related to efficacy and safety.

Dendritic cells containing tumor lysate loaded particles are prepared. The dendritic cells present tumor antigens to elicit the Major Histocompatibility Complex class I pathway and can be used as a vaccine to treat cancer, including ocular melanoma.

The present disclosure relates to vaccine formulations and their use in treating and preventing Chagas Disease.

A CAR-immunocyte targeting an NKG2D ligand can be used in the preparation of a drug. The drug is used for: (i) removing the senescent cell, the NKG2D ligand in the senescent cell being up-regulated by 2-20 times, preferably 4-15 times, more preferably 10-20 times the normal cell; (ii) delaying individual senescence; and/or (iii) preventing and/or treating age-related diseases. The CAR-immunocyte targeting the NKG2D ligand is capable of specifically removing the senescent cell having high expression of the NKG2D ligand, and has higher in-vivo security.

Provided are a polypeptide and nucleic acid for encoding the polypeptide, a nucleic-acid construct, an expression vector, and a host cell containing the nucleic acid, an antigen-presenting cell presenting the polypeptide on the surface of the cell, and immune effector cell thereof, a pharmaceutical composition containing the polypeptide, a vaccine containing the nucleic acid, the nucleic acid construct, the expression vector, the host cell, the antigen-presenting cell, and the immune effector cell, and an antibody recognizing the polypeptide. Also provided is a therapeutic method using the polypeptide, the nucleic acid, the pharmaceutical composition, the vaccine, and the antibody. Also provided are a diagnosis method and diagnosis apparatus for detecting the described polypeptide. Also provided is an application of the polypeptide in preparing a vaccine, a tumor diagnosis kit, or a pharmaceutical composition, and an application of the polypeptide or the nucleic acid as a test target in tumor diagnosis.

Disclosed herein are methods and compositions for treating cancer by eliciting an immune response by administering dendritic cells expressing heterologous proteins. In some embodiments, a dendritic cell comprises one or more heterologous nucleic acid molecules encoding for CD40L and CXCL13. In some embodiments, the dendritic cell further comprises a heterologous nucleic acid molecule encoding for CD93. In yet additional embodiments, the dendritic cells expressing heterologous proteins are activated.

The success of anti-tumor immune responses requires effector T cells to infiltrate solid tumors, a process guided by chemokines. Herein, we demonstrate that in vivo post-translational processing of chemokines by dipeptidylpeptidase 4 (DPP4, also known as CD26) limits lymphocyte migration to sites of inflammation and tumors. Inhibition of DPP4 enzymatic activity enhanced tumor rejection by preserving biologically active CXCL10, and increasing trafficking into the tumor by lymphocytes expressing the counter-receptor CXCR3. Furthermore, DPP4 inhibition improved adjuvant-based immunotherapy, adoptive T cell transfer and checkpoint blockade. These findings provide the first direct in vivo evidence for controlling lymphocyte trafficking through CXCL10 cleavage and support the use of DPP4 inhibitors for stabilizing the biologically active form of chemokines as a strategy to enhance tumor immunotherapy.

Provided are methods, kits and compositions related to toxicity associated with administration of cell therapy for the treatment of diseases or conditions, e.g., cancer, including methods for use in predicting and treating a toxicity. In some embodiments, the toxicity is a neurotoxicity or cytokine release syndrome (CRS), such as a severe neurotoxicity or a severe CRS. The methods generally involve detecting a parameter of a biomarker or individually a parameter of each biomarker in a panel of biomarkers, such as a concentration, amount or activity, and comparing the detected parameter to a reference value for the parameter to determine if the subject is at risk for developing the toxicity, such as neurotoxicity or CRS or severe neurotoxicity or severe CRS. In some embodiments, the methods further involve administering an agent or therapy for treating, ameliorating, preventing, delaying and/or attenuating the development of the toxicity, such as neurotoxicity or CRS, such as severe neurotoxicity or severe CRS.
