The present invention describes methods of preparing a cell composition for treating cancer in a human being by obtaining lymphocytes from a partially or fully HLA-matched healthy donor, activating and expanding T cells reactive to neo-antigens (i.e. new epitopes resulting from somatic mutations in the cancer cell), and enriching for tumor-specific T cells that are not reactive against non-tumor tissue of the cancer patient. Provide herein are lymphocyte compositions comprising partially or fully HLA-matched healthy donor T cells reactive to neo-antigens. Also provided herein are methods of treating human cancer with such neo-antigen-specific, non-alloreactive T cells.

In some embodiments, a product, such as a thermoset, has a polyhexahydrotriazine and a self-polymerized cross-linkable polymer. In some embodiments, a product is the reaction product of a diamine, an aldehyde, and a compound having an α,β-unsaturated electron withdrawing moiety.

The present invention relates to a resin composition, and a brake pad friction material made of the resin composition. The resin composition according to the present invention has high heat resistance and excellent processability, and thus enables the preparation of a brake pad friction material that is capable of securing improved durability and stable brake performance.

An impact resistant polyhexahydrotriazine polymer, processes of forming an impact resistant polyhexahydrotriazine polymer, and an article of manufacture comprising an impact resistant polyhexahydrotriazine polymer are disclosed. The impact resistant polyhexahydrotriazine polymer includes at least one hexahydrotriazine group and at least one chain comprising an allylic portion and a styrenic portion. Variations in the chain control properties of the impact resistant polymer. The process of forming the impact resistant polyhexahydrotriazine polymer includes reactions between formaldehyde and at least two classes of monomer that form hexahydrotriazine groups and impact resistant chains. Adjusting relative monomer concentrations controls properties of the impact resistant polyhexahydrotriazine polymer. The article of manufacture contains a material that has an impact resistant polymer. Impact resistance of the impact resistant polyhexahydrotriazine polymer is dependent upon variation in relative amounts of monomers used in its synthesis.
