The present disclosure provides antibodies that bind complement C1s protein; and nucleic acid molecules that encode such antibodies. The present disclosure also provides compositions comprising such antibodies, and methods to produce and use such antibodies, nucleic acid molecules, and compositions.

Embodiments of the present invention relate to compositions and methods for treatment of subjects in need of or having a bone marrow transplant. Certain embodiments describe compositions and methods for treatment of conditions associated with bone marrow transplantations in a subject, for example, Graft versus Host Disease (GvHD) or bone marrow transplantation rejection. Some embodiments concern early or immediate bone marrow transplantation rejection. Certain embodiments relate to compositions and uses of alpha1-antitrypsin (1-antitrypsin, AAT) and carboxyterminal peptide derivatives thereof and/or compositions and uses of serine protease inhibitors, immunomodulators or anti-inflammatory agent activity similar to that of AAT.

A device for containment of an organ ex vivo and confluent distribution of an ultrasound field to the organ during ex vivo machine perfusion may include a container, a plurality of ultrasound transducers mounted to the container, and a power generator in operable communication with each of the ultrasound transducers. The container may define a reservoir and a plurality of apertures extending through a wall of the container and in communication with the reservoir, with the reservoir being configured for receiving the organ therein. Each of the ultrasound transducers may extend through a respective aperture of the plurality of apertures and may be configured for delivering ultrasound energy into the reservoir and to a respective portion of the organ therein. The power generator may be configured for selectively powering the ultrasound transducers to deliver ultrasound energy.
