Background of invention
Adoptive cellular immunotherapy is meant through infusion self or homospecificity, non-specific antineoplastic immune effector cell, the treat-ment of direct killing tumour cell or virus.Adoptive cellular immunotherapy has got into clinical application; And become the fourth-largest tumor therapeuticing method after operation, radiotherapy, chemotherapy; The CIK cell therapy in the adoptive immunotherapy particularly, cell proliferation rate is fast, killing activity is high because of having, the clinical application spinoff is little etc., and advantage has been widely used in clinical.
CIK cell (Cytokine Induced Killer) refer initially to only accounts for the CD3 of 1-5% in normal human's peripheral blood
+CD56
+The T lymphocyte.The CIK cell of clinical application is through amplification in vitro, with CD3
+CD56
+, CD3
+CD8
+, CD4
+Being main heterogeneous cell mass, is a kind of immune effector cell that wide spectrum kills the knurl vigor that has efficiently, also is the most effectively one of the tumor biotherapy cell of generally acknowledging in the world at present.
The overall efficient of all kinds of T effector cell treatment solid tumors of using vitro culture clinically separately all do not surpass 30%.Wherein to have immunosuppressive agent be major reason to tumour patient.Tumour immunity suppresses the important node-CD4 of network in recent years
+CD25
+FOxp3
+(regulatory T cells, effect Treg) comes into one's own regulatory T cells day by day.In tumor mice, the Treg cell quantity obviously raises.More and more evidences shows that the increase of Treg cell becomes one of major reason that causes tumour immunity escape and restriction immunotherapy of tumors curative effect in the tumor mice.So important step to Treg regulation and control becoming immunotherapy of tumors.
Natural Treg is a thin subgroup of T lymph with immunoregulation effect, accounts for CD4
+The 5%-10% of T cell plays a part to keep the tolerance of body autoimmunization.And increase or during increased functionality, body will be in a kind of state of hyperimmunization tolerance when Treg quantity in the body.Confirm that at present various tumour patients all can detect Treg quantity has the trend of increasing.
Treg performance immune suppression function maybe be through following approach: 1. Treg plays a role through direct cells contacting, or comes the retarding effect cell through secreting the SC factors such as IL-10, TGF-β; 2. retarding effect property CD4
+T cell, CD8
+The activation of T cell, propagation; 3. or via pore-forming protein and granzyme B approach direct killing CD4
+T cell, CD8
+The T cell; 4. the function that suppresses BMDC (DC) through the downward modulation transcription factor NF-KB, suppresses the generation of costimulatory molecules CD80, CD86, CD40 and TNF-α, IL-12; 5. reduce the quantity of the NKG2D acceptor of expressing in CIK or the NK cell, the TGF-β of generation suppresses the cytotoxicity of NK cell; 6. the B cell of suppressor T cell dependence produces Tegeline; 7. suppressing immune effector cell assembles to the tumor by local microenvironment.The effect of Treg cell inhibiting had both occurred in effector cell's activatory initial the unloading phase, occurred in the final effect stage of responsiveness cell performance killing tumor cell effect again, Treg cell pairing effect sexual cell propagation, kills the knurl ability very strong inhibition is all arranged.
Treg exists with the ratio less than 5% in normal human's PMBC (PBMC), but this ratio improves in tumour patient.In addition, IL-2 used during vitro culture CIK cell can induce Treg cell proliferation, and a large amount of IL-10 of justacrine suppress CIK cell proliferation thus, reduce its cell killing ability.Therefore press for to remove and cultivate the Treg cell that transforms in preceding Treg cell, the culturing process, to improve the kill capability of CIK cell.
(Immunomagnetic bead, IMB) technology is a kind of immunological technique that is equaled proposition in 1979 by John Ugelstar to immunomagnetic beads.IMB is the ball-type magnetic particle that is coated with monoclonal antibody, can combine with the target material specifically to make it to have magnetic responsiveness.This technology is widely used in many aspects in medical hygiene field, and has caused the revolution on the bioseparation technology thus.The remarkable advantages that the IMB technology is different from Flow Cytometry is that it can guarantee form and the telotism of separated target cell.That immunomagnetic bead technique also has simultaneously is highly sensitive, specificity is high, detection speed is fast, good reproducibility, simple to operate and do not need expensive advantages such as plant and instrument.Carrying out cellular segregation with the IMB technology has dual mode, and a kind of is that the method for directly from cell mixture, isolating target cell is called positive the separation; The method that makes target cell be able to purifying with the irrelevant cell of IMB removal is called negative the separation.Therefore can utilize immunomagnetic beads that the Treg cell among the PBMC is removed.
Foxp3 is specific expressed on the T cell for research proof such as Rudensky in 2003, and Foxp3 is that Treg cell development institute is essential, in the growth of modulating T cell, plays important effect.Foxp3 is the cytocerastic important switch of Treg.Do not have the Treg cell without Foxp3, so we can utilize the activity that suppresses Foxp3, the generation of Treg cell in the control CIK cell cultures.
IL-21 is the IL-2 family member, mainly by CD4
+T emiocytosis is all found its acceptor on T cell, NK cell, B cell.IL-21 can promote the propagation and the function of T cell, NK cell, and can promote CD8
+The cell antitumor action.IL-21 can suppress CD4
+CD25
+The expression of main attemperator's transcription factor Foxp3 of Treg reduces CD4
+The T cytodifferentiation forms the Treg cell, thereby correspondingly suppresses the generation of Treg cell.Therefore we utilize the immunological magnetic bead sorting technology before the CIK cell cultures, to remove the Treg cell, add IL-21 in the culturing process, reduce CD4
+The T cell be differentiated to form the Treg cell, to improve the immunotherapy effect of CIK cell.
Well-known IFN-γ, CD3 monoclonal antibody, IL-2 are the major cytokine that stimulates CIK, but the preceding IL-2 that addressed can induce Treg cell proliferation, and a large amount of IL-10 of justacrine suppress CIK cell proliferation thus, reduce its cell killing ability.We find also that in CIK cell preparation process adding IFN-γ stimulates, and apoptosis can take place PBMC, has influenced the amplification of cell, so IL-2, IFN-γ should not add too much.And PHA to PBMC induce effect identical with IFN-γ, and have efficiently short proliferation function, can be used as the strong activator of T cell, promote the immunologically competent cell precursor to transform to immunologically competent cell.Therefore we recommend to substitute part IFN-γ with PHA.The toxicity of CIK cell needs to improve, and Sodium Selenite is cheap, can improve the toxicity of CIK cell, so we add Sodium Selenite when being recommended in the CIK cell cultures.
