The present disclosure provides methods for predicting and thereby treating cancer or increasing the efficacy of an anti-cancer medication, in part by measuring checkpoint proteins on extracellular vesicles released from non-cancer cells. These checkpoint proteins promote cancer progression and/or compensate for the loss of signal from the checkpoint proteins being inhibited by the checkpoint inhibitory therapy. Compositions and methods of treatment are also provided.

The invention relates to methods to evaluate in one single assay the biocompatibility of materials based on the simultaneous determination of the phagocytosis, cell activation and cell death produced by said materials, preferably, in peripheral blood or other human cells and proximal fluids. The invention also relates to a kit to perform the method of the invention.

A lipidated secondary antibody is disclosed. Particles comprising same are also disclosed.

The invention features a substrate and compositions, kits, devices, and methods employing the substrate that produces an isolated population of cells from a general population. The isolated population is enriched for one or more target populations. Substrate is can be liquefied and allows recovery of unlabeled, viable, and functional cells.

Disclosed are a novel therapeutic means effective and practical against cancer, and a novel substance useful as such a therapeutic means. Provided are novel peptides derived from a partial region of HMGN1, HMGN2, HMGN4 or HMGN5, and anti-cancer agents and anti-cancer effect enhancers containing the peptide as an active ingredient. The peptide of the present invention has an anti-tumor effect even independently, and exerts a remarkably excellent anti-tumor effect particularly when used in combination with an immune checkpoint regulator, or an anti-CD4 antibody or antigen-binding fragment thereof.

Methods and compositions are described that can be used as a pre-treatment for HIV therapies.

The present invention provides monovalent antibodies with a long half-life when administered in vivo, methods of making such monovalent antibodies, pharmaceutical compositions comprising such antibodies, and uses of the monovalent antibodies.

Fusion polypeptides including at least one Fc binding domain linked to at least one integrin binding domain are provided. In some embodiments, the at least one Fc binding domain is one or more Fc binding domains from Protein A, Protein G, or Protein Z and the at least one integrin binding domain comprises one or more fibronectin type III domains (for example repeats 12-14 of fibronectin type III domains and optionally the connecting segment of fibronectin). Protein complexes including the polypeptide and one or more antibodies are also provided. Methods of using the polypeptide and/or polypeptide:antibody complex are provided, including treating a subject with a tumor, inducing an immune response to a tumor, and/or targeting an antibody to a tumor cell.

Disclosed herein is a personalized tumor vaccine comprising attenuated cancer cells and a method of using said personalized tumor vaccine to treat cancer.
