  • Publication number: 20260226170
    Abstract: Provided herein are designs of multi-specific polypeptides for binding target cells and engaging T cells. In some embodiments, the multi-specific polypeptide comprises a first binding domain that specifically binds to a T cell receptor beta variable region (TCR?V), or a T cell receptor alpha variable region (TCR?V) expressed on the T cell, and a second binding domain that specifically binds to an antigen (e.g., CD19) on the target cell, and a Fc region. In some embodiments, both the first and the second binding domains are located on the same polypeptide chain of the Fc region (e.g., a Fc region polypeptide chain comprising a Knob mutation). These multi-specific polypeptides are not only effective in killing the target cells, but also expands early memory populations that maintains and/or replenishes effector populations over time.

  • Patent number: 12657371
    Abstract: Systems as described herein may include document scanning to identify problems with the documents. A document scanning system may determine a scope of a document scan. The system may initiate a silent mode of a browser application and send a request to access an enterprise document repository. The system may be granted read-only access and determine page elements associated with a document within the scope. Based on the page elements, the system may use a machine learning model to determine an indication of one or more problems with a document. Accordingly, the system may generate a health report for each document within the scope of the document scan.

  • Publication number: 20260066151
    Abstract: Disclosed is a cable assembly including at least one conductor and a metal sheath disposed over the at least one conductor, the metal sheath including a continuous strip of metal having a plurality of revolutions. A first revolution of the plurality of revolutions may include a first section having a curved profile extending into an interior cavity of the metal sheath, and a second section extending from the first section, the second section extending along a lengthwise axis, wherein a length of the second section, along the lengthwise axis, is at least two times as large as a diameter of the first section when the metal sheath is in a linear configuration. The first revolution may further include a third section extending from the second section, the third section including a free end terminating within a recess defined by a curved profile of a first section of an adjacent revolution.
