Description

The amplification in vitro method of tumor infiltrating lymphocyte TIL
Technical field
The invention belongs to biological fields, are related to a kind of method of amplification in vitro tumor infiltrating lymphocyte TIL.
Background technology
Immunization therapy is a kind of emerging oncotherapy mode, has been listed in the 4th kind after operation, radiotherapy, chemotherapy Therapeutic modality gradually plays a significant role in the complex treatment of tumour.2010, U.S. FDA approval was first thin in the world The Provenge listings of born of the same parents' immunotherapeutic product, fully show value of the cellular immunotherapy in oncotherapy.
Tumor infiltrating lymphocyte (tumor-infiltrating lymphocyte, TIL) is present in mesenchyma stroma of tumors The heterogeneous lymphocyte population based on lymphocyte, be gathered in mostly around tumour or its interstitial in shell-like surround cancer Nest.Its main component is the T lymphocytes being present in mesenchyma stroma of tumors, and fraction is the unrestricted NK cells of MHC, common Characterized by expression T cell receptor (T cell receptor, TCR).TIL come from tumor tissue sections, can specific recognition swell self Tumor has the special restricted dissolving tumor promotions of MHC.The Rosenberg etc. of U.S. NCI is confirmed for the first time, from solid tumor mass The TIL of separation after IL-2 activation and large amplification, can be used for the treatment of advanced melanoma patient, therapeutic effect in vitro LAK (the lymphokine activatedkiller cells) cell therapy technology (document developed before significantly larger than: Expansion of human tumor infiltrating lymphocytes for use in immunotherapy trials.J Immunol Methods 1987).In recent years the more clinical tests report display delivered, til cell immunization therapy 20%~40% advanced melanoma can be cured, fully shows TIL as cellular immunotherapy means in oncotherapy Potentiality (document:A new approach to the adoptive immunotherapy of cancer with tumor- infiltrating lymphocytes.Science 1986)。
But there are 2 points of deficiencies for the method for amplification in vitro TIL at present:
