Abstract: Provided herein are compositions, methods and uses involving antibodies that bind to ErbB, a receptor tyrosine kinase, and modulate the activity of ErbB. Also provided are uses and methods for treating disorders, such as cancer, by administering to subject an antibody that binds to ErbB.

Abstract: The present disclosure provides methods for modulating the interaction between a TAM ligand and a lipid membrane containing phosphatidyl serine (PtdSer). In one example, such methods use a TAM receptor agonist having a PtdSer-containing lipid bilayer membrane with Gas6 and/or Protein S bound to the membrane to activate signaling from one or more TAM receptors and treat an autoimmune disease. In another example, methods are provided for treating a subject with a pathological condition characterized by overactivation of TAM signaling and/or reduction in Type I IFN response, such as infection by an enveloped virus, by use of agents that decrease the interaction between a TAM ligand and PtdSer. Also provided are methods for classifying a virus as susceptible to anti-TAM therapy. Methods of identifying an agent that blocks virus infectivity are also provided.

Abstract: Provided herein are ALK regulators for the treatment of diseases and disorders. For example, presented herein are ALK regulators, e.g., ALK activators, and methods of treatment and/or prevention of diseases, including neurodegenerative, neuromuscular and cognitive diseases or disorders, and methods of enhancing cognitive abilities using ALK regulators, e.g., ALK activators. Also provided herein are ALK regulators, e.g., ALK inhibitors, and methods of treatment and/or prevention of diseases such as hyperproliferative and neoplastic disorders associated with cells that express ALK, e.g., cells that exhibit increased or constitutive levels of ALK tyrosine phosphorylation using such ALK regulators, e.g., ALK inhibitors. Pharmaceutical compositions of said ALK regulators, e.g, ALK activators and inhibitors are likewise provided.

Abstract: Provided herein, in one aspect, are antibodies that immunospecifically bind to a human KIT antigen comprising the fourth and/or fifth extracellular Ig-like domains (that is, D4 and/or D5 domains), polynucleotides comprising nucleotide sequences encoding such antibodies, and expression vectors and host cells for producing such antibodies. The antibodies can inhibit KIT activity, such as ligand-induced receptor phosphorylation. Also provided herein are kits and pharmaceutical compositions comprising antibodies that specifically bind to a KIT antigen, as well as methods of treating or managing a KIT-mediated disorder or disease and methods of diagnosing a KIT-mediated disorder or disease using the antibodies described herein.
