Abstract: The methods and compositions described herein address the need in the art by providing peptides and polypeptides comprising a growth factor binding domain. In some embodiments, the peptides have an amino acid sequence that is at least 80% identical to one of SEQ ID NOS:1-7, 13-15, 49-50, or 66-70, or a fragment thereof; wherein the peptide is less than 300 amino acids in length.

Abstract: Aspects of the present disclosure provide methods and compositions for treatment of autoimmune disorders including, for example, multiple sclerosis and rheumatoid arthritis. Also disclosed are methods for promoting wound healing. Certain aspects are directed to antiinflammatory cytokines operatively linked to an albumin protein. Further aspects relate to methods for delivering an anti-inflammatory cytokine to a lymph node.

Abstract: The disclosure is directed to methods of inhibiting coronavirus infection using a hydrocarbon stapled peptide which is a peptidomimetic of the human angiotensin-converting enzyme 2 (hACE2). The hydrocarbon stapled peptide binds to the receptor binding domain (RBD) of a coronavirus spike protein (S) and inhibits binding of the coronavirus to hACE2 expressed on the surface of host cells.

Abstract: Aspects of the disclosure are directed to methods, systems, and compositions for detecting antibodies capable of binding to angiotensin II. Certain aspects comprise detection of antibodies capable of binding to angiotensin II in a sample from a subject, where the subject has or has had a coronavirus infection, such as a SARS-CoV-2 infection. Also disclosed are vaccine compositions comprising a portion of SARS-CoV-2 Spike protein, where such compositions do not induce generation of angiotensin II-binding antibodies.

Abstract: Provided herein are nanoparticles to encapsulate therapeutic agents and methods of use thereof for intracellular delivery and disease treatment. In particular, the present disclosure provides polymersomes for use in the delivery of therapeutic agents, e.g. stapled peptides, to diseased (e.g. cancer) cells.

Abstract: Peptides that specifically bind erythrocytes are described. These are provided as peptidic ligands having sequences that specifically bind, or as antibodies or fragments thereof that provide specific binding, to erythrocytes. The peptides may be prepared as molecular fusions with therapeutic agents, tolerizing antigens, or targeting peptides. Immunotolerance may be created by use of the fusions and choice of an antigen on a substance for which tolerance is desired. Fusions with targeting peptides direct the fusions to the target, for instance a tumor, where the erythrocyte-binding ligands reduce or entirely eliminate blood flow to the tumor by recruiting erythrocytes to the target.

Abstract: The methods and compositions described herein address the need in the art by providing compositions and methods for a therapy with an antibody that is specifically targeted to and/or retained intra- or peri-tumorally, limiting systemic exposure and reducing side-effects. Accordingly, aspects of the disclosure relate to a composition comprising an immunotherapeutic antibody operatively linked to an extracellular matrix (ECM)-affinity peptide. An ECM-affinity peptide is one that has affinity for an extracellular matrix protein.

Abstract: Several embodiments of the present disclosure relate to therapeutic compositions configured to target the liver of a subject and that are useful in the treatment or prevention of one or more of transplant rejection, autoimmune disease, food allergy, and immune response against a therapeutic agent. In several embodiments, the compositions are configured to target the liver and deliver antigens to which tolerance is desired. In several embodiments, the compositions are configured for clearance of a circulating protein or peptide or antibody associated with one or more of the above-mentioned maladies. Methods and uses of the compositions for induction of immune tolerance are also disclosed herein.

Abstract: Several embodiments of the present disclosure relate to glycotargeting therapeutics that are useful in the treatment of transplant rejection, autoimmune disease, food allergy, and immune response against a therapeutic agent. In several embodiments, the compositions are configured to target the liver and deliver antigens to which tolerance is desired. Methods and uses of the compositions for induction of immune tolerance are also disclosed herein.

Abstract: Provided herein are polymer materials that find use in, for example, delivery of short-chain fatty acids. In particular, polymers are provided that form stable nanoscale structures and release their payload, for example, by cleavage of a covalent bond (e.g., via hydrolysis or enzymatic cleavage). The polymers are useful, for example, for delivery of payloads (e.g., SCFAs) to the intestine for applications in health and treatment of disease, and have broad applicability in diseases linked to changes in the human microbiota including inflammatory, autoimmune, allergic, metabolic, and central nervous system diseases, among others.

Abstract: Hydrodynamic methods for conformally coating non-uniform size cells and cell clusters for implantation, thus preventing immune rejection or inflammation or autoimmune destruction while preserving cell functionality. A method for conformally coating cells and c clusters with hydrogels that are biocompatible, mechanically and chemically stable and porous, with an appropriate pore cut-off size. The methods of the invention are advantageously reproducible and result in a relatively high yield of coated versus non-coated cell clusters, without compromising cell functionality. Conformal coating devices configured to perform the methods of the invention, methods of optimally utilizing said devices and purifying the coated islets, and coated biomaterials made by said methods.
