SELECTIVE REMOVAL OF AGE-MODIFIED CELLS FOR TREATMENT OF ATHEROSCLEROSIS
20190328876 · 2019-10-31 ·

A method of treating atherosclerosis comprises removing AGE-modified cells from a patient. The AGE-modified cells include erythrocytes, intima cells, endothelial cells, smooth muscle cells, macrophages, and foam cells. A variety of techniques, such as ultrasound and binding with an anti-AGE antibody, may be used to identify and remove the AGE-modified cells.

System and method for selecting and culturing cells

A cell processing system includes at least one processor connectable to a source container filled with a biological fluid, the at least one processor including a spinning membrane configured to receive and separate target cells from the biological fluid, the target cells exiting at a first outlet, one or more containers selectively connected to the first outlet; and, and a magnet. The system also includes a controller coupled to the at least one processor and configured to operate the spinning membrane to receive biological fluid from the source container and to direct the target cells to one of the one or more containers, to pause to permit magnetic particles to be associated with the target cells, and to operate the spinning membrane to receive the contents of one of the one or more containers with the magnet applied to the target cells associated with the magnetic particles.

20190298908 · 2019-10-03 ·

This invention is directed to a process for depleting one or more targeted substances such as toxins, proteins such as one or more immune checkpoint inhibitors (ICI), or a combination thereof from a subject. Immune checkpoint inhibitors (ICI), such as PD-1 protein, PD-1 ligand (PD-L1), CTLA-4, LAG-3, TIM3 and others are known to be involved in inhibition of T-cell activation in tumor patients. This invention is also directed to a device for depleting ICI such as PD-1 protein, PD-1 ligand (PD-L1) including soluble PD-L1 (sPD-L1), PD-L2, CTLA-4 including soluble form sCTLA-4, LAG-3, TIM3, or toxins from a subject. This invention is further directed to the use of the process and the devices for treating medical conditions such as cancers, other diseases and substance overdose.

Systems and methods for use and control of an automated separator with adsorption columns

Blood treatment systems and methods are provided for combining a blood separation system and an adsorption device. The blood separation system is configured to separate a blood component from blood, while the adsorption device is configured to receive at least a portion of the separated blood component and process it. The blood separation system includes a fluid flow element and a controller. The fluid flow element is configured for flowing the separated blood component into the adsorption device. The controller controls the fluid flow element based at least in part on one or more processing parameters. The processing parameters include a maximum flow rate of the separated blood component flowed into the adsorption device, a maximum pressure of the separated blood component flowed into the adsorption device, and/or the volume of fluid in a location of the system.

IMMUNOADSORPTION
20190269800 · 2019-09-05 · ·

Upon administration of rAAV vectors the humoral immune response (neutralizing antibodies) is the first barrier that needs to be overcome. Surprisingly it was found that by using immunoadsorption for depletion of immunoglobulins from the blood (plasma), subjects can be highly efficiently treated with rAAV vectors, i.e. obtain highly efficient transduction after rAAV vector administration, in spite of the presence of high levels of nAb.
