重組抗CD20單克隆抗體工程細(xì)胞珠的構(gòu)建
[Abstract]:Malignant lymphoma is an immune cell tumor of the lymphoid tissue of the lymph node and the junction, which is derived from the malignant transformation of lymphocytes or histiocytes, of which the non-Hodgkin's lymphoma (NHL) is more difficult to cure. The cure rate of the disease is only 25% after radiotherapy and chemotherapy, and therefore, a new treatment scheme is needed for the treatment of recurrent, intractable low-grade or follicular non-Hodgkin's lymphoma. In the treatment of B-cell lymphoma, the CD20 molecule is an ideal target antigen, expressed above 95% of the normal or deteriorated B-cell surface. It is initially expressed in the pre-B-lymphocyte (pre-B) stage, and the end of the differentiation of the B-cell terminal into the plasma cell has been considered to be a unique identification of the surface of the B-cell. Anti-CD20 monoclonal antibodies bind to CD20 on B-cells and elicit an immune response to B-cell lysis, which may include complement-dependent cytotoxicity (CDC) and antibody-dependent cell-mediated cytotoxicity (ADCC)[2]. The use of monoclonal antibodies against B-cell lymphoma antigen CD20 molecules is an important protocol for the treatment of non-Hodgkin's lymphoma. Through the global multi-center clinical trial, the survival rate of the tumor patients is obviously improved, the quality of life of the patients is obviously improved, the curative effect of the life cycle is prolonged, and the drug has the characteristics of small toxic and side reaction, compared with the standard tumor treatment drugs adopted at present. To date, at least 500,000 non-Hodgkin's lymphoma patients have received treatment with anti-CD20 monoclonal antibodies, one of the world's most successful antibody drugs, Rituximab for treatment of non-Hodgkin's lymphoma, produced by Roche,[[I]], has a global sales of around $6 billion in 2011, and it is clear that the development of such a drug will provide significant benefits for patients with tumors, and can bring huge economic and social benefits to the biotechnology company for the development of such drugs, and has a wide market prospect. The purpose of this project is to construct an engineering cell bead to express the active ingredient, that is, the recombinant anti-CD20 monoclonal antibody has the same amino acid sequence as the rituximab. A light chain and a heavy chain gene fragment of a recombinant anti-CD20 monoclonal antibody, including a signal peptide, was synthesized according to the literature, and inserted into a pREA202 mammalian cell expression vector, respectively, to construct a vector p REA202/ REA202L and a p REA202/ REA202H expressing an antibody light chain and a heavy chain, respectively. CHO-DG44 cells are co-transfected with the vector of the constructed expression antibody light chain and the heavy chain through the liposome, the positive clone is screened by the G418 resistance, the clone of the high-expression antibody is screened by ELISA, and then the cell strain CHO-REA 202 with a high expression antibody is finally obtained by using the MTX step-by-step pressure screening and cloning. The preliminary identification of the engineering cell line shows that the expression product is intact anti-CD20 monoclonal antibody, and the expression ability of the antibody can reach 20 to 23PCD (pg/ cell/ day). the cell bank is established by the cell line, and after the cell bank of the working cell is recovered, the cell bank is continuously transmitted and cultured, and the stability of the engineering cell is examined. According to the results of the study, the seed cell culture stage was transferred to one generation, and the production and culture stages were each incubated for 48 hours as a generation. The cells were passaged for 60 passages, and the cells of 0, 10, 20, 40 and 60 passages were collected. The results showed that in the course of the passage of CHO-REA202, the DNA sequence of the heavy chain gene of the REA202 protein was not changed; the level of the copy number of the heavy chain gene of the REA202 protein did not change significantly; the growth characteristics, the doubling time and the morphology of the cells did not change significantly; The expression level of the REA202 protein did not change significantly. The results show that the CHO-REA202 of the engineering cell has good passage stability and is in accordance with the requirements for the passage stability of the cell in the Chinese Pharmacopoeia.
