Molecular determinants of cancer response to immunotherapy are described, as are systems and tools for identifying and/or characterizing cancers likely to respond to immunotherapy.

Targeting or binding peptides to neutrophil elastase for specific targeting of activated neutrophils includes amino acid sequences substantially similar to a reactive center loop portion of alpha-1 anti-trypsin (AAT).

Provided herein are methods for the production of native and reconstituted hyaluronan (HA) complexes containing pentraxin-3 (PTX3) and heavy chain 1 (HC1) of inter alpha inhibitor (IαI). Compositions containing the complexes and therapeutic methods using the complexes are provided. Combinations and kits for use in practicing the methods also are provided.

The present disclosure presents a general approach to engineering existing protein-protein interactions through domain addition and evolution. The disclosure teaches the creation of novel fusion proteins that include knottin peptides where a portion of the knottin peptide is replaced with a sequence that has been created for binding to a particular target. Such fusion proteins can also be bispecific or multi specific in that they can bind to and/or inhibit two or more receptors or receptor ligands. Knottins may be fused with an existing ligand (or receptor) as a general platform tor increasing the affinity of a ligand-receptor interaction or for creating a multi specific protein. In addition, the fusion proteins may comprise a knottin peptide fused to another protein where the other protein facilitates proper expression and folding of the knottin.

The present invention relates to, inter alia, an engineered cell (e.g., iPSC, IPS-derived NK, or NK cell) comprising a disrupted B2M gene and an inserted polynucleotide encoding one or more of SERPINB9, a fusion of IL15 and IL15Rα, and/or HLA-E. The engineered cell can further comprise a disrupted CIITA gene and an inserted polynucleotide encoding a CAR, wherein the CAR can be an anti-BCMA CAR or an anti-CD30 CAR. The engineered cell may further comprise a disrupted ADAM17 gene, a disrupted FAS gene, a disrupted CISH gene, and/or a disrupted REGNASE-1 gene. Methods for producing the engineered cells are also provided, and therapeutic uses of the engineered cells are also described. Guide RNA sequences targeting described target sequences are also described.
