Provided herein are T-cell receptor (TCR) fusion proteins (TFPs), T-cells engineered to express one or more TFPs, and methods of use thereof for the treatment of diseases, including cancer.

A vaccine comprising a pharmaceutically acceptable carrier and bacteria which presents at least one cancer-associated antigen is disclosed. The bacteria are not genetically modified to express the at least one cancer-associated antigen. Uses thereof are also disclosed.

Disclosed herein is a Chlamydia-activated B cell (CAB) platform. Also disclosed is a method of enhancing a population of B cells, comprising exposing said B cells to Chlamydia spp. under conditions suitable to enhance the population of B cells, such that expansion and differentiation of said B cells takes place, and said B cells are exposed or crosslinked to an antigen. Also disclosed are methods of producing said CABs, and treating a subject in need thereof with said CABs.

The present disclosure provides customizable enucleated erythroid cells or enucleated cells that can be engineered to include, on their surface, a loadable exogenous antigen-presenting polypeptide, wherein the loadable exogenous antigen-presenting polypeptide comprises one or more amino acid substitutions. In some embodiments, the one or more amino acid substitutions stabilize the loadable exogenous antigen-presenting polypeptide on the cell surface. In some embodiments, the loadable exogenous antigen-presenting polypeptide is stabilized on the cell surface in the absence of a polypeptide bound to the loadable exogenous antigen-presenting polypeptide. In some embodiments, the loadable exogenous antigen-presenting polypeptide comprises an exogenous displaceable polypeptide bound to the loadable exogenous antigen-presenting polypeptide. In some embodiments, the loadable exogenous antigen-presenting polypeptide is stabilized on the cell surface upon release of the displaceable polypeptide.

A method for obtaining a plurality of pluripotent adult olfactory stem cells (APOSCs) includes isolating the APOSCs, culturing the isolated APOSCs in a sphere culture medium, and collecting the cultured APOSCs that express Bmi-1 (B-lymphoma moloney murine leukemia virus insertion region-1), Oct-4 (Octamer-binding transcription factor 4), Sox-2 (Sex-determining region Y (SRY)-box 2), Nanog, SSEA-4 (Stage-specific embryonic antigen-4), ki67, c-Myc, KLF-4 (Kruppel Like Factor 4), K14 (Cytokeratin 14) and ICAM-1 (Intercellular Adhesion Molecule 1).

A silicified cell replica includes a silicified cell or a silicified subcellular fragment. The silicified cell replica may be used to induce an immunological response, treat a bacterial infection, or treat a patient with cancer.

Some aspects of this disclosure provide engineered exopolysaccharide-associated proteins, engineered bacteria expressing such proteins, and engineered biofilms comprising such proteins. Some aspects of this disclosure provide methods for engineering exopolysaccharide-associated proteins, and for the generation of engineered bacteria and biofilms expressing or comprising such proteins. Some aspects of this disclosure provide compositions and methods useful for the generation of vaccines and the vaccination of subjects, for delivering molecules of interest to a target site, for example, a surface, for purification of molecules of interest, for example, from bioreactors comprising engineered bacteria as provided herein, and for bioremediation applications, such as the cleanup of environmental pollutants.

A method for the repair of a unit, by specific diagnosis of the undesired state, and its appropriate repair, using said specific diagnosis as a means to repair in an appropriate way said unit. The diagnosis and repair processes may involve chemical, physical, or mechanical means. The units being diagnosed and repaired include live matter (e.g. human beings, animals, plants) as well as non-live matter (e.g. buildings, electronic equipment, polymer materials).

The present invention relates generally to the field of ocular therapeutics and the development thereof for use in humans and animals including mammals and birds. More particularly, it relates to subunit vaccines that are effective against pathogens causing infections thereof for use in humans and animals including mammals and birds. The present invention specifically provides a novel vaccine formulation suitable for ocular immunization comprising a subunit vaccine antigen in an amount to provoke a protective immune response and at least two adjuvants of which one is corpuscular. It further provides a method for inducing a local and systemic immune response and methods for preventing recurrence of ocular infections and/or modulates the occurrence and/or severity of sequels.
