Libraries of immunoglobulins which each have one or more amino acid modifications in at least one structural loop region of such immunoglobulins, where the modified loop region specifically binds to an epitope of an antigen to which an unmodified immunoglobulin does not significantly bind.

The disclosure provides, in part, follistatin polypeptides that are suitable for use in local administration and methods for use.

CAR-T cells for cancer therapy are provided with an antibody that recognizes the MAGE-A4-derived-peptide/HLA-A2 complex. The antibody includes the VH amino acid sequence of SEQ ID NO: 36 and the VL amino acid sequence of SEQ ID NO: 38. The antibody preferably is provided with the amino acid sequence of SEQ ID NO: 32. Such CAR-T cells can be used in CAR infusion therapy in which a cancer-specific intracellular antigen is used.

The invention relates to methods of identifying compounds that modulate mTORC1 activity in a cell by modulating the activity of SAMTOR, as well as to the use of such identified compounds in the modulation of mTORC1 and the treatment of diseases and conditions characterized by aberrant mTORC1 activity.

A conjugate of a physiologically active polypeptide and immunoglobulin Fc with attenuated immune response is disclosed. Also disclosed are a method for preparing the conjugate, a composition for reducing an immune response including the conjugate, and a method for reducing the immune response of the physiologically active polypeptide. A method for maintaining the reduction in the intrinsic binding affinity of the conjugate for an Fc gamma receptor and/or a complement, and a composition including the conjugate are also disclosed.

Provided is a method for preparing genetically-modified T cells expressing chimeric antigen receptor, comprising: (i) a step of preparing non-proliferative cells holding a viral peptide antigen, which are obtained by stimulating a group of cells comprising T cells using an anti-CD3 antibody and an anti-CD28 antibody followed by culturing in the presence of the viral peptide antigen and a treatment for causing the cells to lose their proliferation capability; (ii) a step of obtaining genetically-modified T cells into which a target antigen-specific chimeric antigen receptor gene has been introduced using a transposon method; (iii) a step of mixing the non-proliferative cells prepared by step (i) with the genetically-modified T cells obtained by step (ii), and co-culturing the mixed cells; and (iv) a step of collecting the cells after culture.
