    • The invention relates to a method for the preparation of efficient antigen-presenting human γδ T cells, to the γδ T cells prepared by such a method, and to their use in immunotherapy, vaccination, vaccine development and diagnostics. Similar to dendritic cells (DCs) in potency and efficacy, these human γδ T cells process antigens and present antigenic peptides to αβ T cells and induce antigen-specific responses (proliferation and differentiation) in naïve αβ T cells. γδ T cells are easily purified from peripheral blood, acquire "maturation" status (expression of essential adhesion, co-stimulatory and major histocompatibility complex molecules) within 1 day of in vitro culture under stimulation and induce strong primary and secondary T helper cell and cytotoxic T cell responses. The γδ T cells may be used in a method of treatment of tumors or chronic or recurrent infectious diseases, in identification of novel tumor or pathogen-derived antigens, and in the diagnosis of the immune competence of a patient.
    • 本发明涉及一种制备有效的抗原呈递人类β细胞的方法,涉及通过这种方法制备的γdT细胞,以及它们在免疫治疗,疫苗接种,疫苗开发和诊断中的应用。 类似于树突状细胞(DCs)的效力和功效,这些人类T细胞处理抗原并将抗原肽存在于β细胞中并诱导幼稚T细胞中的抗原特异性应答(增殖和分化)。 β细胞可以从外周血中轻松纯化,在刺激前1天内获得“成熟”状态(必需粘附,共刺激和主要组织相容性复合物分子的表达),诱导强的初级和辅助性T辅助细胞 细胞毒性T细胞应答。 βT细胞可用于治疗肿瘤或慢性或复发性传染病,鉴定新型肿瘤或病原体衍生的抗原以及诊断患者免疫能力的方法。
