Methods and materials for generating and using complexes that contain erythrocytes coupled to polypeptides, and particularly to erythrocyte-polypeptide complexes that can interact with biological molecules, are provided herein.

The present disclosure is directed, in some embodiments, to methods and compositions of comprising a cell having a non-internalizing receptor, and a nanoparticle surface-modified with a ligand that binds to the non-internalizing receptor.

The present invention relates to processes and systems for preparing nanoparticles, cellular or viral membranes and/or cellular or viral membrane coated nanoparticles using or comprising, inter alia, a multi-inlet vortexing reactor, tangential flow filtration (TFF) and/or a high shear fluid processor such as a microfluidizer (or a microfluidizer processor). The present invention also relates to the nanoparticles, cellular or viral membranes and/or cellular or viral membrane coated nanoparticles prepared by the present processes and systems, and the uses and/or applications of the nanoparticles, cellular or viral membranes and/or cellular or viral membrane coated nanoparticles.

The present disclosure provides ex vivo armed T cell (EAT) compositions that comprise multi-specific (e.g., bispecific) antibodies that bind to CDS and at least one additional target antigen (e.g., antigen that is expressed by tumor cells and/or a DOTA label). The EAT compositions of the present technology are useful for adoptive immunotherapy in a subject in need thereof.

The present invention relates to a use of CD133 involved in resistance to an EGFR-targeting agent in colon cancer. The CD133 protein may be used as a novel target protein for diagnosing and treating resistant cancer as well as general cancer.

Described are conjugates of nucleic acid nanotubes and cells by linking the nanotubes to a cell surface moiety. Devices, kits, systems, and methods comprising the nanotube cell conjugates are also described.

Provided herein are peptide amphiphiles (PAs). In some embodiments, provided herein are targeting PAs comprising a PA backbone and a targeting moiety. In some embodiments, the peptide amphiphiles are assembled into nanofibers. In some embodiments, provided herein are cells coated with a targeting PA or a nanofiber comprising the same, and methods of use thereof

The present invention relates to methods for developing engineered immune cells such as T-cells for immunotherapy that have a higher potential of persistence and/or engraftment in host organism. IN particular, this method involves an inactivation of at least one gene involved in self/non self recognition, combined with a step of contact with at least one non-endogenous immunosuppressive polypeptide. The invention allows the possibility for a standard and affordable adoptive immunotherapy, whereby the risk of GvH is reduced.

Provided herein are engineered cells, comprising: a chemical or biological moiety covalently bound to a cell surface glycan, wherein the chemical or biological moiety is selected from the group consisting of small molecule, polynucleotide, polypeptide, and antibody. Also provided are compositions comprising these engineered cells and methods of making and using the same.

The present invention relates to a use of CD133 involved in resistance to an EGFR-targeting agent in colon cancer. The CD133 protein may be used as a novel target protein for diagnosing and treating resistant cancer as well as general cancer.
