Methods of protecting against neurodegeneration

The disclosure provides a method of preventing or reducing protein aggregates using combretastatin-A4 (CA4) or an analog thereof. The disclosure also provides methods of reducing the risk, delaying the onset, delaying or slowing the progression, or reversing the signs or symptoms of a neurodegenerative (or other age-progressive) disease using a combretastatin-A4 (CA4) or an analog thereof. The combretastatin-A4 (CA4) or an analog thereof may bind glial fibrillary acidic protein (GFAP). The combretastatin-A4 (CA4) or an analog thereof is described by compounds of Formula (I).

Inhibition of dendritic cell-driven regulatory T cell activation and potentiation of tumor antigen-specific T cell responses by interleukin-15 and MAP kinase inhibitor

The invention involves the discovery that if dendritic cells loaded with a tumor antigen are cultured in interleukin-15 (IL-15), or if T cells activated by the dendritic cells are cultured in IL-15, Treg activity that is specific for the tumor antigen is reduced. This reduction in Treg activity results in an increase in anti-tumor immune response. Another embodiment of the invention involves the discovery that incubating dendritic cells with a MAP kinase inhibitor in combination with IL-15 gives synergistic benefits when the dendritic cells are used to activate T cells. Dendritic cell and T cell compositions incubated with IL-15 or a MAP kinase inhibitor are provided.

Method of Coating Surfaces with Nanoparticles for Biological Analysis of Cells

A method of coating a surface with nanoparticles for biological analysis of cells that includes the steps of cleaning the surface with an oxidizing acid, treating the surface with an organosilane, coating the surface with nanoparticles, and then growing cells on the surface coated with the nanoparticles. The surface may be a glass surface, a silica-based surface, a plastic-based surface or a polymer-based surface. The nanoparticles may be gold-based nanomaterials.
