Abstract

PURPOSE:The titled stimulating material having a stimulating agent capable of inducing powerful tumor damaging cells safely with good operability by contact with a peripheral leukocytes through covalent bonds to an insoluble carrier. CONSTITUTION:A leukocytic stimulating material for treating malignant tumors obtained by bonding a stimulating agent, e.g. lectin having the action of activating lymphocytes, particularly T lymphocytes, inducing tumorous cells by contact with peripheral leukocytic cells through covalent bonds to an insoluble carrier, e.g. a fibrous material such as agarose or dextran, in the form of particles, fibers, hollow fibers or membranes, etc. The resultant material has the ability to activate human leukocytes more powerfully in the state of bonded to the insoluble carrier without dissolving the stimulating agent in a culture medium. Activated leukocytes are mixed with human tumorous cells to destroy most of the tumorous cells by damage and induce powerful tumor damaging cells. Thus the material is effective for cancers of the stomach, lungs, the breast, liver, etc.

As is well known, it has been reported that killer T cells, NK cells, activated macrophages, K cells, and the like play important roles as antitumor cells that serve as an immune surveillance mechanism against malignant tumors in living organisms.

Therefore, as immunological therapy for malignant tumors,
It is considered that cancer patient immune cells (white blood cells) are activated to efficiently induce these anti-tumor cells. However, it has been reported that the immune function of cancer patients generally decreases as the cancer progresses, and the presence of immunosuppressive factors that suppress the immune response or the presence of suppressor T cells and suppressor macrophages in cancer patients. Induced activation has been reported.

It must be said that it is difficult to efficiently induce antitumor cells in living cancer patients whose immune capacity is in such a suppressed state. Therefore, it is thought that taking patient's leukocytes out of the body, which has been released from the immunosuppressive state, and efficiently inducing and activating antitumor cells outside the body will become a new and highly effective cancer immunotherapy.

Killer T cells are thought to play a major role in anti-cancer immunity, accounting for 41% of anti-tumor cells, and research has been intensively conducted to induce and activate them outside the body. In other words, the patient's tumor cells are sensitized to the cancer patient's peripheral blood white blood cells taken out of the body, and the patient's white blood cells are activated to produce killer T cells that specifically damage only the patient's tumor cells but not the patient's normal cells. This is an attempt to treat cancer by inducing it and returning it to the body of a cancer patient.

However, the killer T cells induced by this method are not strong enough to be expected to have a therapeutic effect, so they are cultured using T cell growth factor, a type of lymphoid, and are grown in large quantities. A method of administering the drug is being considered. Although this method is possible because T-cell growth factors can be industrially mass-produced through genetic engineering techniques9 and it has become a reality that large amounts of i-cell growth factors can be used, it is not possible to use killer T cells in vitro. There are problems such as cell deterioration due to long-term culture. In addition, there are various other problems that make it difficult to put it into practical use, such as the need for surgery with patient tumor cells to induce killer T cells, and the fact that killer T cells are only available in some cancer patients. There are many problems that need to be solved, such as the ability to induce cells but not the gold side, and the extremely complicated operation.

The present inventors have developed a new method for inducing and activating tumor-toxic cells, which is dramatically more practical than conventional methods.
Using readily available substances as stimulants, b1 was developed using various lymphocyte activating substances in order to find a method to induce and activate potent tumor-toxic cells in almost all cancer patients in a short period of time and with ease of use. I searched for. Among these lymphocyte activating substances, lectins have been shown to induce strong tumor-toxic cells, but these are generally high-molecular, heterologous proteins, have strong antigenicity, and are highly reactive to leukocytes. binds with affinity to

Therefore, after activating a patient's leukocytes with lectin, even if the activated leukocytes are thoroughly washed, the lectin will not be removed from the leukocyte membrane surface, and there is a high possibility that the lectin will be carried into the patient's body together with the leukocytes. It is important to avoid administering foreign proteins to patients. In addition, this tumor-toxic cell induction and activation method consists of operations such as collecting leukocytes from a cancer patient, culturing the leukocytes in an appropriate medium containing a stimulant, washing and collecting the activated leukocytes, and administering them to the patient. All operations must be performed aseptically and are quite complicated. Therefore, in order to make this therapy possible, the system must be devised and its operability improved.

As a result of intensive research in line with the above objectives, the present inventors surprisingly found that when human peripheral blood leukocytes were brought into contact with stimulation materials in which various leukocyte stimulants were covalently bonded to insoluble carriers, It was found that tumor-toxic cells were more strongly induced than when using a binding stimulant, and that the stimulant was not detected on the membrane surface of activated leukocytes. In other words, when the stimulant is not dissolved in the medium but bound to an insoluble carrier, it has the ability to more strongly activate human leukocytes, and when activated leukocytes are mixed with human tumor cells, they are cultured for 4 hours. The present inventors discovered that most tumor cells are damaged and destroyed, and that strong tumor-toxic cells are induced, leading to the completion of the present invention.

The insoluble carrier used in the present invention can be either a hydrophilic carrier or a hydrophobic carrier, but when a hydrophobic carrier is used, non-specific adsorption of serum components to the carrier occurs. gives better results. The shape of the insoluble carrier may be any known shape such as particulate, fibrous, hollow fiber, or membrane. As the granular or spherical insoluble carrier, those having a particle size of 1 micron to 3000 micron can be used. If the particle size is 1 micron or less, it is difficult to separate it from activated leukocytes. Particularly, if the particle size is 50 microns or more, it is possible to easily separate the particles from activated leukocytes, and if the particle size is 3000 microns or more, the contact area per unit weight of the carrier with the leukocytes decreases, so it is preferable. 0 More preferably, particles having a particle size of 80 to 2000 microns are suitable in the present invention. Further, if the specific gravity of the granular or spherical insoluble carrier is 1.07 or more, it can be easily separated from active leukocytes by centrifugation or standing still. In addition, when using a flat membrane-like or hollow fiber-like porous carrier, use one with a pore size of 0.05 to 10 S'cron, which does not allow cells to pass through but allows medium components to freely pass through. Nutrients can be supplied to the leukocytes from the outer surface of the membrane, and it is possible to stimulate and activate a high concentration of leukocytes. More preferably, a porous carrier having a pore size of 0.1 to 5 microns can be used successfully.

All known methods such as covalent bonding, ionic bonding, and physical adsorption can be used to identify the stimulant on the surface of the insoluble carrier, but considering the dissolution properties of the stimulant,
It is preferable to use it by fixing it with a covalent bond. For this purpose, known methods commonly used in immobilized enzymes and affinity chromatography can be used. For example, by activating agarose, sepharose, etc. with hydrogen bromide (CNBr), or by reacting silica glass beads with γ-aminopropyltriethoxysilane to obtain alkylamino glass, which is activated with glutaraldehyde, it can be used as a stimulant. A method such as bonding can be used. Furthermore, if necessary, a molecule (spacer) of any length may be introduced between the insoluble carrier and the stimulant.

Activation of peripheral blood leukocytes by a stimulant-bound insoluble carrier is
When carried out in a serum-containing medium, strong tumor-toxic cells can be induced. That is, a medium containing 2 to 20% of animal serum such as fetal bovine serum, bovine serum, horse serum, or human serum is prepared. Preferably, a medium containing 2 to 20% human serum is prepared. The medium in this case is a medium commonly used for animal cell culture, for example, RPM11640.
Medium, MEM medium, etc. can be used. However, RPM11640 medium supplemented with serum components such as serum albumin can also be used.

Peripheral blood leukocytes collected by various methods are suspended in the prepared medium at a cell concentration of 0.5 to 3 x 106 cells/ml, and an appropriate amount of a stimulant-bound insoluble carrier is added thereto.
Culture is carried out at a temperature of 25-45C. At temperatures below 25C, there is almost no effective activation of white blood cells;
Above this, the survival rate of leukocytes decreases. Cultivation can be easily carried out in a CO2 incubator using a commercially available plastic container for cell culture. After several hours of culture, leukocytes adhere to the surface of the stimulant-bound insoluble carrier particles and are activated.
