Abstract: Compositions comprising an MHC ligand peptide covalently attached to an MHC class II molecule are provided herein. In some compositions, the MHC ligand peptide is covalently attached to the MHC class II molecule by a peptide linker, wherein the MHC ligand peptide or the peptide linker comprises a first cysteine, wherein the MHC class II a chain or a portion thereof or the MHC class II ? chain or a portion thereof comprises a second cysteine, and wherein the first cysteine and the second cysteine form a disulfide bond such that the MHC ligand peptide is bound in a peptide-binding groove formed by the MHC class II a chain or the portion thereof and the MHC class II ? chain or the portion thereof. Also provided are nucleic acids encoding such compositions and methods for using such compositions to elicit an immune response in a subject.

Abstract: The present invention provides a novel class of antibodies and antigen binding fragments thereof that bind the extracellular domain of ErbB3 receptor and inhibit various ErbB3 functions. For example, the antibodies and antigen binding fragments described herein are capable of binding to the receptor designated ErbB3 and inhibiting EGF-like ligand mediated phosphorylation of the receptor. Such antibodies and antigen binding fragments thereof have the useful characteristic of inhibiting the proliferation of cancer cells expressing ErbB3.

Abstract: The disclosure provides, among other aspects, neutralizing antibodies and portions thereof that bind to ActRIIB and uses for same.

Abstract: The present invention provides, inter alia, a method for cell-specific modulation of a target antigen. The method comprises contacting a target cell having the target antigen on the surface of the target cell with: (a) first multi-specific antigen-binding polypeptide comprising: (i) a cell-specific antigen binding domain (C1), (ii) a target antigen binding domain (T1); and (b) a second multi-specific antigen-binding polypeptide comprising: (i) a cell-specific antigen binding domain (C2), (ii) a target antigen binding domain (T2); wherein C1 and C2 interact with the same cell-specific antigen, and the cell-specific antigen and the target antigen are on the same target cell. Pharmaceutical compositions and kits thereof are also included in the present invention.

Abstract: A method, computer program product, and system for detecting and fencing off a failed entity instance so that failover time in the computing system is reduced. Upon detection of a failed entity, for example a failed process, a signal handler invokes an operating system interface to fence off the failed instance from modifying its persistent state, so that the entity may be re-instantiated prior to termination of the failed instance. This approach reduces failover time and eliminates split-brain problems without compromising access to the failed instance to obtain diagnostic information, core dumps, and the like.
