Therefore, as an immunological therapy for malignant tumors, it is conceivable to activate cancer immune cells (white blood cells) and efficiently target these anti-tumor cells. However, it has been reported that patients with cancer generally have a decline in their immune function as the cancer progresses, and the presence of immunosuppressive factors that suppress the immune response (Tr) in patients' bodies. has been reported to activate suppressor T cells and suppressor macrophages.

It must be said that if the immune system is in such a suppressed state, it will be difficult to efficiently induce anti-tumor cells in the body. Taking the patient's leukocytes out of the body, releasing them from the immunosuppressive state, and efficiently targeting and activating anti-cancer cells outside the body is considered to be a new highly effective immunotherapy. .

Killer T cells are thought to play a major role in anti-cancer immunity among anti-tumor cells, and intensive research is being carried out to activate them outside the body. That is, the peripheral blood leukocytes of a 7'C cancer patient taken out of the body are sensitized to the excised 'fc patient's tumor cells, activating the patient's leukocytes and specifically damaging only the patient's tumor cells,

Any hydrophobic carrier can be used. The shape of the insoluble carrier is
Any known shapes such as particulate, fibrous, hollow fiber, and membrane shapes can be used. As the granular or spherical insoluble carrier, those having a particle size of 1 micron to 3000 microns can be used. If the particle size is less than 1 micron, it will be difficult to separate 111 m from activated leukocytes. In particular, if the particle size is 50 microns or more, activated leukocytes can be easily separated by filtration, but if the particle size is 3,000 microns or more, the contact area of the carrier unit M amount with the leukocytes decreases. Undesirable. The particle size is preferably 80 to 2000 microns. The specific gravity of the spherical insoluble carrier is 1.07.
If this is the case, separation from activated leukocytes can be easily performed by centrifugation or standing still. In addition, when a hollow fiber-like porous carrier is used, the flat membrane-like b has a pore size of 0.05 to 0.05 to 0.05, which allows cells to pass through but medium components to freely pass through.
If a bone with a diameter of 10 microns is used, it will bind to the 10,000 sides of the membrane, supply nutrients to the white blood cells from the other side of the membrane, and stimulate and activate high-δ white blood cells.

In particular, porous carriers in the form of flat membranes or hollow fibers with pore diameters of 0.1 to 5 microns can be used favorably.
