演講題目:快速有效預測CAR-T/NK療效及副作用
演講摘要:準確迅速地預測CAR T/NK細胞治療的臨床效能及其毒副作用是當今免疫細胞治療中未解決的關鍵問題之一。目前,沒有任何一個單一參數可以精準有效地預測CAR T/NK的臨床療效及其可能存在的毒副作用。隨著免疫細胞治療的高速發展,我們可以推測臨床醫生在選擇不同藥企相似的CAR T/NK細胞產品時將面臨困境。 醫療市場缺乏高通量并排評估不同藥企相似的CAR T/NK細胞產品對同一適應癥病人的臨床效能及其毒副作用。 該研究中,我們通過高通量,定量檢測CAR T/NK免疫突觸的質量來預測其臨床效能和毒副作用。該技術,可能為免疫細胞的個體化,精準治療引入新的臨床檢測指標及新的預測工具。

演講題目:人羊膜干細胞旁分泌作用促進皮膚組織再生機制的研究
演講摘要:移植干細胞促進組織修復,除了其分化為所修復組織的細胞外,也許更重要的方式是干細胞的旁分泌作用改善受損組織的微環境,啟動組織自身干細胞增殖和分化來修復損傷。已有研究表明干細胞可產生微泡,其內含有各種活性蛋白因子、還可以含有mRNA、miRNA甚至線粒體等細胞器。這將對損傷組織微環境產生非常大的影響。人羊膜干細胞包括羊膜間充質干細胞和羊膜上皮干細胞,人羊膜干細胞是最具活力的干細胞之一,具有很強的增殖能力和分化潛能,還具有很強的旁分泌能力。人羊膜干細胞的移植將會明顯影響損傷組織的微環境,促進受損組織的修復。我們對人羊膜干細胞進行了mRNA和miRNA測序,分析了其可能產生的旁分泌活性蛋白質,并通過搜集含有其旁分泌產物的培養液,分別作用于皮膚角質形成細胞、皮膚成纖維細胞和血管內皮細胞,研究其旁分泌作用對它們的影響。發現其旁分泌產物能不同程度的促進這些細胞的增殖、遷移和分化,并研究了產生這些作用的主要分子,用這些分子在體外作用于皮膚角質形成細胞、皮膚成纖維細胞和血管內皮細胞,進行進一步的研究,同時通過動物實驗在整體水平進行研究,深入探討羊膜干細胞旁分泌作用促進皮膚再生的分子機理。期望以后能通過這些分子直接改善受損組織的微環境,促進組織的再生,達到治療皮膚損傷的目的。

演講題目: Research and application of mesenchymal stem cells: My 20-Year Journey
演講摘要:Mesenchymal stem cells (MSCs) were first defined as a group of cells which were of self-renewal ability, were able to be culture-expanded for a prolonged period of time, and are able to differentiate into various lineages of connective progenies originated from embryonic mesoderm including bone, cartilage and adipose tissues. These cells were first isolated from bone marrow; subsequently, MSCs isolated from other sources such as liposuction fat, synovial tissues and trabecular bone have been reported by other investigators. Recently, it was reported that certain population of stem cells in human bone marrow, although low in frequency, were able to differentiate into cells and tissues originated from not only mesoderm, but also ectoderm.
In our laboratory, we have successfully isolated and culture-expanded MSCs from human bone marrow and umbilical cord blood using negative immuno-selection and limiting dilution methods. Surface phenotype of these cells was performed using flow cytometry and surface marker phenotype was characteristic of MSCs. These MSCs were able to differentiate into progenies originated from all three germ layers including osteoblasts, chondrocytes, adipocytes, neuroglial cells and hepatocytes. In vitro functionality of these differentiated progenies was also demonstrated. Particularly, MSC-differentiated hepatocytes have been shown to be able to secrete urea and uptake of low density lipoproteins is also noted in these MSC-differentiated hepatocytes.
There are various applications of MSCs in biomedical research both in vitro and in vivo. The in vitro model of MSC culture can serve as an excellent model to study the control of differentiation as well as the cell fate in each lineage. Novel genes and proteins that control differentiation can also be explored in this model. Besides, it can also be used for screening of new drugs and compounds. Most important of all, MSCs are indispensable in the study of cell therapy, tissue engineering and regenerative medicine.
Over the years, we have published more than one hundred peer-reviewed research articles to report our findings regarding the molecular mechanisms that govern the fate choice and differentiation, as well as the plasticity andapplications of MSCs. In particular, our efforts made to elucidate how MSCs sense and respond to biophysical and mechanical stimuli have substantially contributed to the understanding of mechanobiology in MSCs.
In summary, it is foreseeable that in the near future, MSCs will revolutionize the treatment of a variety of diseases. Therefore, more efforts should be made to further elucidate the basic science of MSCs to accelerate their clinical translation from bench to bedside.

演講題目:Use CRISPR Gene Editing To Improve CAR-T/TCR-T Adoptive Immunotherapy For Cancers (CRISPR/CAS9技術用于促進腫瘤CAR-T/TCR-T細胞的過繼性免疫治療)
演講摘要:CAR-T 治療白血病和淋巴瘤已進入商業化進程。然而,不同于血液系統腫瘤,實體腫瘤的免疫治療更為復雜,難度更高,并且需研發新的技術攻克。CAR-T /TCR-T 治療實體腫瘤需多方面的突破, 尤其是靶的特異性, 克服腫瘤微環境的抑制及提高T細胞本身的質量。基因編輯技術,尤其是CRISPR/CAS9簡單高效基因編輯技術的高速發展,對CAR-T/TCR-T攻克實體瘤提供了廣泛的應用前景。本報告介紹了如何通過應用CRISPR/CAS9基因編輯技術對CART或TCR-T進行改造來制備通用型或功能增強型CAR-T或TCR-T并用于臨床。我們發現, 敲除內源性TCR的TCR-T在體外實驗或小鼠腫瘤模型中,可以達到和親和力增強型TCR一樣好的效果而不用擔心脫靶副作用。同時,應用不同的小鼠腫瘤模型,通過應用CRISPR/CAS9基因編輯技術敲除免疫檢查點分子PD1, CTLA4和Tim-3可明確增強CART或TCR-T療效,尤其把PD1-CD28轉換分子與Tim-3敲除同時應用。通過復雜的T細胞修飾,有望對腫瘤過繼性免疫治療有突破性進展。帶PD1-CD28轉換分子的Tim-3敲除的TCR-T細胞不但可以抵制腫瘤誘導的T細胞功能低下,在體外還可抵抗TGFb,Adenosine和抑制性T細胞(Treg)的抑制作用。

TOPIC: Developing CAR Treg for Treating Autoimmune Disease
SUMMARY:The recent FDA approvals of the first two CAR T cell treatments for blood cancers (Kymriah? and Yescarta?) mark the beginning of a new era. This is a fast progressing area. We can expect that there will be continuation of success on CAR-T in the blood cancers with reduced toxicity, reduced rate of relapse etc. There will be breakthrough on solid tumors by the CAR-T therapy, and off-the-shelf treatment will become a reality. In addition, the technology of genetically modified T cells will move beyond oncology. The Development of CAR-Treg cell therapy to target autoimmune diseases and induction of tolerance will likely be the next wave. At TxCell, we are developing CAR Treg for autoimmune disease and organ transplant rejection. HLA A2 appears to be an ideal target for organ transplant rejection, as HLAs are membrane-bound protein specifically expressed on the transplanted tissues, HLA A2 expression level is high, it can robustly induce CAR-Treg activity. It has high allelic frequency--about 25% transplanted organs are HLA A2 mismatched in North America. We are developing HLA A2 CAR-Treg therapy for organ transplant rejection and will start the first ever clinical trial using CAR-Treg cells. We have shown that HLA A2 CAR-Treg cells can prevent GVHD in a mouse model. Other proof of concept data will also be presented.

演講題目:全自動、全封閉CAR-T細胞的制備工藝探討
演講摘要:CAR-T細胞治療在血液惡性腫瘤的臨床試驗中表現出了巨大的潛力。但是T細胞的體外基因修飾涉及到諸多步驟,尤其是在新藥監管模式的要求下,要在GMP條件下制備出合格的CAR-T細胞、而且這樣的制備工藝還必須能滿足未來產業化的要求,就成為了一個CAR-T細胞發展中必須克服的障礙。
國家食品藥品監督管理總局藥品審評中心近日發布了關于《細胞制品研究與評價技術指導原則》(試行版),不僅正式明確了CAR-T細胞按照藥品評審原則監管,而且在制備工藝上明確指出了“全封閉、全自動”的發展要求。楊林博士將針對CAR-T細胞的工業制備,結合自身的發展經驗,進行系統闡述和比較,為CAR-T細胞產業的工業化發展,指明方向。
