AllerMAbs.jpg

艾乐美生物科技有限公司(AllerMAbs Co., Ltd.)成立于2015年,是台湾一家专注于生产高亲和力、高纯度并具有过敏原特异性的嵌合人类IgE单克隆抗体的生物公司。公司创办人团队在科研过程中发现市面上缺乏多样的IgE单克隆抗体,特別是具有过敏原特异性的人IgE 单抗。如果能制备出这种抗体,将有助于IgE 相关领域的研究工作。因此,AllerMAbs公司团队开始思考与研究利用基因克隆动物来制造人类 IgE 抗体的可行性,经过数年的努力于 2014年开发出人类IgE 抗体基因嵌入小鼠,通过杂交瘤技术 (Hybridoma technology),成功地研制出分泌嵌合人类IgE 单抗的 IgE 杂交瘤与纯化 IgE 抗体。经测试,此种嵌合人类IgE 单抗的物化性质与对免疫细胞的活性,皆与人类IgE 抗体一致,研究成果于2015 年发表在国际学术期刊上。

 

AllerMAbs的产品解决了目前人类IgE抗体不易制备的问题,让嵌合人类IgE抗体可以成为人类IgE抗体的替代品,并提供一个更稳定、更符合血清IgE检测系统的校正品,让临床血清IgE的检测结果更加准确与可靠。

 

其利用动物基因转殖技术,将组成人类IgE抗体分子的ε重链(Heavy chain)和κ轻链(Light chain)的编码基因(Encoding genes),分別嵌入(Knock-in)小鼠胚胎干细胞(Embryonic stem cells, ES cells)的γ1重链和κ轻链基因的位置,接着把胚胎干细胞分別植入孕母鼠体内,并将其带有嵌入基因之成鼠交互配种,最后得到带有人类IgE抗体重链和轻链基因的基因嵌入小鼠(HεκKI mice),且体内能制造完整的嵌合人类IgE抗体分子。

Dendritics.jpg

Dendritics公司主要关注人类树突状细胞,希望找到能够促使CD34+造血前体细胞转化为树突状细胞(在GM-CSF和TNF-alpha存在的情况下)的细胞因子。在1992-2005年间,大量的研究使得研究者对人类树突状细胞的产生、细胞通路、C-type凝集素受体的功能及Toll-like受体的活性有了更深的理解。

 

DENDRITICS was started in 2005 by former members of SCHERING PLOUGH Laboratory for Immunological Research (LIR) in Dardilly, France. From their long experience at LIR, the team members of DENDRITICS have gathered complementary scientific and technological knowledge in different areas of immunology. The initial focus of LIR was in the biology of B lymphocytes, elaboration of human monoclonal antibodies, and in cytokine discovery (IL-3, IL-4, IL-7, IL-10, IL-17, GM-CSF) together with our colleagues of DNAX Research Institute in Palo Alto, California.

 

Our interest in cytokines led to the finding that human dendritic cells (DCs) could be generated in vitro from CD34+ hematopoietic progenitors cultured in the presence of GM-CSF and TNF-alpha.

 

The period from 1992 to 2005 saw the specialization of LIR in DC biology and was fuelled by a large-scale effort to discover and study the function of genes specifically expressed by these cells. This program led to a number of findings that contributed in particular to understanding the heterogeneity of DCs, the pathways regulating DC migration, the function of C-type lectin receptors in DCs and the activity of Toll-like receptors in DCs. Many novel genes were discovered through screening of cDNA libraries or through monoclonal antibodies raised against DCs.
