    摘要: Provided herein are methods of identifying a protein capable of binding a ligand, the method comprising: (a) contacting the ligand with two or more samples comprising a plurality of proteins in a solution; (b) separating the proteins bound to the ligand (“bound proteins”) from the proteins that are not bound to the ligand (“unbound proteins”) in each sample; (c) denaturing and digesting the bound proteins to form a plurality of peptides in each sample; (d) quantifying a plurality of molecular features contained in the plurality of peptides in each sample, wherein the molecular features are defined as having a mass to charge ratio, retention time, and peak intensity as measured by mass spectrometry; and (e) ranking the molecular features that exhibit a statistically significant difference in quantity between the samples contacted with the ligand and a sample that is not contacted with the ligand (“statistically significant molecular feature”).

    摘要: The present invention relates to oncolytic vaccinia viruses which have been modified to promote anti-tumor immunity and/or reduce host immunity and/or antibody response against the virus. It is based, at least in part, on the discovery that oncolytic vaccinia virus (i) bearing a genome deletion of a gene that reduces T cell immunity (interleukin-18 binding protein); (ii) treated with a sialidase enzyme which is believed to reduce TLR2 activation and therefore the antibody response; (iii) carrying a gene that enhances cytotoxic T lymphocyte induction (e.g., TRIF) and/or (iv) reduces tumor myeloid-derived suppressor cells by reducing prostaglandin E2 reduces tumor growth. Accordingly, the present invention provides for immunooncolytic vaccinia viruses and methods of using them in the treatment of cancers.
