The present disclosure relates to compositions and methods for restoring endothelial glycocalyx. Exemplary compositions include nanoparticle compositions of preassembled glycocalyx.

Provided antibodies or antigen-binding fragment thereof specific for the variant exon v9 of the CD44 gene (CD44v9), antibody-drug-conjugate (ADC), and other derivative comprising the antibodies or antigen-binding fragment. Provided nucleic acid molecules encoding the same, and methods of making the same. Further provided pharmaceutical compositions comprising the same, and the use of the same in treating diseases or in the manufacture of a medicament for the treatment of the diseases, such as cancer.

A recombinant nucleic acid expression construct including a first nucleic acid sequence region encoding a chimeric antigen receptor (CAR), a second nucleic acid sequence region encoding a checkpoint inhibitory molecule, and a third nucleic acid sequence region encoding an immune stimulatory cytokine. A recombinant nucleic acid expression construct encoding the CAR specifically recognizes CD44v6, and includes a PD1 checkpoint inhibitory molecule, and an immune stimulating cytokine. Further aspects relate to genetically modified cells, including a recombinant nucleic acid expression construct encoding the CAR, wherein the cells are preferably immune cells, more preferably NK cells or cytotoxic T lymphocytes or T helper cells. Medical use of the cells may be in the treatment of a medical disorder associated with the presence of pathogenic cells expressing CD44v6, preferably cancer cells, more preferably cancer stem cells of solid or liquid malignancies.

An antibody recognizing the O-acetylated-GD2 ganglioside for the treatment of Cancer Stem Cells (CSC) cancer, a pharmaceutical composition including the antibody for treating a CSC cancer and a method for treating a CSC cancer in a patient in need thereof, the method including administering the antibody to the patient. A method for diagnosing a CSC, the use of the O-acetylated-GD2 ganglioside as a biomarker of CSC cancer, and a method for predicting the response of a subject affected with CSC cancer to a treatment with the antibody or the composition are also described.

Ligand-cytotoxic drug conjugates, pharmaceutical compositions, preparation methods, and pharmaceutical uses thereof are provided. More specifically, a ligand-cytotoxic drug conjugate of general formula Pc-(X-Y-D).sub.n is provided. The ligand-cytotoxic drug conjugate can be used to treat cancer via receptor modulation.

Disclosed herein are non-myeloablative antibody-toxin conjugates and compositions that target cell surface markers and related methods of their use to effectively conditioning a subject's tissues (e.g., bone marrow tissue) prior to engraftment or transplant. The compositions and methods disclosed herein may be used to condition a subject's tissues in advance of, for example, hematopoietic stem cell transplant and advantageously such compositions and methods do not cause the toxicities that are commonly associated with traditional conditioning methods.

Provided herein are methods of treating a subject with cancer using a therapeutically effective amount of one or more one or more tumor-specific antibody-IR700 molecules. The methods can further include administering to the subject a therapeutically effective amount of (a) one or more CTLA4 antibody-IR700 molecules, one or more PD-L1 antibody-IR700 molecules, or combinations thereof, (b) one or more reducing agents, (c) one or more immunoactivators, or combinations of a, b, and c, for example, either simultaneously or substantially simultaneously with the tumor-specific antibody-IR700 molecules, or sequentially (for example, within about 0 to 24 hours). The method also includes irradiating the subject or cancer cells in the subject (for example, a tumor or cancer cells in the blood) at a wavelength of 660 to 740 nm at a dose of at least 1 J/cm.sup.2. The use of one or more reducing agents can reduce edema resulting from treatment.

The present disclosure relates to a truncated body of IL7R. The amino acid sequence of the truncated body of IL7R s a sequence shown in SEQ ID NO. 1. A T cell expressing a chimeric antigen receptor containing the truncated body of IL7R can effectively kill a tumor cell.

A system and method for coupling a cutting slate atop a cooler lid. The cutting slate can be used to allow a user to cut, slice, and prepare food on the cutting slate without damaging the top of the cooler. The cutting slate can be coupled or secured to the cooler.

Antibodies are provided that alter the TLR4 signaling pathway to produce an immunosuppressive effect. The antibodies are useful for the treatment or prevention of an unwanted immune response in a subject, such as autoimmune disease, transplant rejection, and allergic reactions.
