The present invention generally relates to systems and methods for targeted removal of a substance or biomolecule such as a protein from a biological fluid, such as blood. In some cases, the blood may be withdrawn from a subject, treated, and returned to the subject. Previous techniques for removal of biological materials from blood, such as hemodialysis and plasmapheresis, were generally non-specific (i.e., they removed a multitude of proteins/toxins from the blood). By contrast, novel methods and devices described herein are capable of removing specific or single substances such as proteins from biological fluids such as blood in a specific manner. Such highly specific protein removal has a broad array of clinical applications, including treatment of inflammatory conditions and autoimmune diseases.

Provided herein are bedside, parenterally patient connected, closed-loop and complete systems and methods for cell purification.

The invention relates to a system, comprising: a) a sample processing unit, comprising an input port and an output port coupled to a rotating container having at least one sample chamber, the sample processing unit configured provide a first processing step to a sample or to rotate the container so as to apply a centrifugal force to a sample deposited in the chamber and separate at least a first component and a second component of the deposited sample; and b) a sample separation unit coupled to the output port of the sample processing unit, the cell separation unit comprising separation column holder (42), a pump (64) and a plurality of valves (1-11) configured to at least partially control fluid flow through a fluid circuitry and a separation column (40) positioned in the holder, the separation column configured to separate labeled and unlabeled components of sample flowed through the column.

The disclosure provides an apparatus for processing a blood sample, a device for cells preparation and a method thereof. The disclosure can be used for blood separation, cell culture and preparation of cells. The apparatus mainly uses a weight sensor to have the weight and some liquid sensors. By optimizing the connection relationship of each device in the whole equipment, simplifying the operation process of the equipment, coordinating each step of the device, reducing the production cost, integrating the steps of PBMC cell separation and magnetic bead separation, the method makes the cell preparation process more intelligently automated, the operation simpler, the cell pollution reduced and the success rate of cell preparation improved. It has broad application prospects and huge market value.

The invention is directed to the removal of serum gal-3 from circulation by plasmapheresis, comprising at least in part donor apheresis, using gal-3 binding agents in either a fixed bed, or in a form easily removed, such as by being complexed with magnetic particles. This method, on its own, brings a sharp reduction and relief from the inflammation and fibroses that can be induced by circulating gal-3. The process may be combined with the administration of gal-3 binding agents, such as modified citrus pectin, to further lower unbound gal-3 levels, to the point where gal-3 in the tissues may be addressed. This method may also be combined with removal of TNF receptors to provide an effective treatment for cancer.

The present invention relates to compositions and methods for destroying target cells in a patient using photodynamic therapy. In particular, the present invention provides a photosensitizing agent based on a small molecular weight (<50 kDa) protein or peptide or a small molecule that is conjugated to a phthalocyanine dye, such as IRDye 700DX.

The invention provides methods of making immune effector cells (e.g., T cells, NK cells) that can be engineered to express a chimeric antigen receptor (CAR), and compositions and reaction mixtures comprising the same.
