Abstract:

The present invention relates to antibodies, e.g., full length antibodies or antigen binding fragments thereof, that specifically bind to BCMA (B-Cell Maturation Antigen) and/or CD3 (Cluster of Differentiation 3). The invention also relates to antibody conjugates (e.g., antibody-drug-conjugates) comprising the BCMA antibodies, compositions comprising the BCMA antibodies, and methods of using the BCMA antibodies and their conjugates for treating conditions associated with cells expressing BCMA (e.g., cancer or autoimmune disease). The invention further relates to heteromultimeric antibodies that specifically bind to CD3 and a tumor cell antigen, (e.g., bispecific antibodies that specifically bind to CD3 and BCMA). Compositions comprising such heteromultimeric antibodies, methods for producing and purifying such heterodimeric antibodies, and their use in diagnostics and therapeutics are also provided.

Abstract:

Systems and methods are described herein for a media guidance application that detects, and responds to, a user's review of video content on a media device. The media guidance application detects a rewind operation during playback of a video comprising a media asset. In response, the media guidance application determines if the playback position reached during the rewind operation occurs during a first break in the media asset and, if so, identifies objects depicted in the video at the playback position, and presents auxiliary video relating to an object at a second break in the media asset.
