  • Publication number: 20240139251
    Abstract: Disclosed herein are methods of producing tumor antigen-specific T cells and uses thereof. In the present method, peripheral blood mononuclear cells (PBMCs) isolated from a subject are cultivated with bi-specific antibodies (BsAbs) in a culture medium so as to produce the tumor antigen-specific T cells from the PBMCs. Also provided in the present disclosure are tumor antigen-specific T cells produced by the present method, and uses thereof in treating subjects suffering from cancers.

  • Publication number: 20240113639
    Abstract: A power conversion circuit for driving motor and a control method thereof are provided. The control method includes: comparing a control command with a carrier wave to acquire a PWM signal; identifying whether a phase difference between the output voltage and current falls within a range; if the phase difference falling within the range, determining whether a zero-sequence voltage is positive or negative according to the output voltage and current; injecting the zero-sequence voltage into the control command to acquire a synthesized command, and detecting maximum and minimum voltage values of the synthesized command after a period; according to the zero-sequence voltage determined to be positive or negative, selecting the maximum or minimum voltage value to perform a logic reversal operation; after stopping injecting the zero-sequence voltage, acquiring an output expected value; and comparing the output expected value with the carrier wave for adjusting a duty ratio of PWM signal.

  • Patent number: 11913025
    Abstract: Provided are methods of inducing differentiation and/or proliferation of T cells and uses thereof. In the present method, peripheral blood mononuclear cells (PBMCs) isolated from a subject are cultivated with bi-specific antibodies (BsAbs) in a culture medium so as to differentiate the PBMCs into the T cells. Each of the T cells has an anti-tumor antigen moiety and an anti-CD3 moiety on its surface. Also provided are methods and pharmaceutical kits for treating subjects suffering from cancers.

  • Patent number: 11680107
    Abstract: The present disclosure relates to a biodegradable and thermosensitive hydrogel composition comprising a diblock PLGA-PEG copolymer and a triblock PLGA-PEG-PLGA copolymer. A method for treating or alleviating one or more symptoms of a disease and a method for delivering an active agent are also provided.

  • Patent number: 11571476
    Abstract: The present invention relates to an anti-tumor/anti-tumor-associated fibroblast (TAF)/anti-hapten trispecific antibody (TsAb). The anti-hapten domain enables TsAb to arm various hapten-conjugated anti-cancer drugs (nanocarrier drugs, small molecule drugs, protein drugs, and radioactive drugs). The anti-tumor domain enables TsAb-armed drugs to target tumor cells, while the anti-TAF domain enables the TsAb-armed drugs to target TAFs. The present invention allows the simultaneous killing of tumor cells and TAFs by various drugs through arming with TsAb.

  • Patent number: 11369690
    Abstract: Disclosed herein is a bi-specific antibody that specifically directs a therapeutic agent to a cancer cell by targeting a tumor antigen of the cancer cell, and thereby suppressing the growth of the cancer or blocking the invasion or metastasis of the cancer. The bi-specific antibody of the present disclosure includes a first antigen binding site that binds to polyethylene glycol (PEG); and a second antigen binding site that binds to a target ligand, such as a tumor antigen.

  • Publication number: 20210292438
    Abstract: A monomeric bispecific polyethylene glycol (PEG) engager that includes an anti-PEG Fab fused to a disulfide stabilized scFv that specifically binds to a cell surface antigen. The PEG engager, in the absence of PEG, remains monomeric upon binding to the cell surface antigen on a cell and remains on the surface of the cell. Also disclosed is a method for treating cancer by administering a PEG engager followed by a PEGylated anti-cancer agent. Further disclosed is a method for diagnosing a cell-mediated disorder by administering a PEG engager followed by a PEGylated diagnostic agent.
