A method for overcoming immune suppression includes the steps of inducing production of naïve T cells and restoring T cell immunity. A method of vaccine immunotherapy includes the steps of inducing production of naïve T cells and exposing the naïve T cells to endogenous or exogenous antigens at an appropriate site. Additionally, a method for unblocking immunization at a regional lymph node includes the steps of promoting differentiation and maturation of immature dendritic cells at a regional lymph node and allowing presentation of processed peptides by resulting mature dendritic cells, thus, for example, exposing tumor peptides to T cells to gain immunization of the T cells. Further, a method of treating cancer and other persistent lesions includes the steps of administering an effective amount of a natural cytokine mixture as an adjuvant to endogenous or exogenous administered antigen to the cancer or other persistent lesions; preferably the natural cytokine mixture is administered in combination with thymosin.
一种克服免疫抑制的方法包括诱导产生幼稚 T 细胞和恢复 T 细胞免疫的步骤。疫苗免疫疗法的方法包括诱导产生幼稚 T 细胞和在适当部位使幼稚 T 细胞接触内源性或外源性抗原。此外,一种解除区域淋巴结免疫障碍的方法包括以下步骤:促进区域淋巴结未成熟树突状细胞的分化和成熟,并允许由此产生的成熟树突状细胞呈现处理过的多肽,从而,例如,将肿瘤多肽暴露给T细胞,以获得T细胞的免疫。此外,一种治疗癌症和其他顽固性病变的方法包括以下步骤:施用有效量的天然细胞因子混合物作为内源性或外源性给药抗原的辅助剂,以治疗癌症或其他顽固性病变;优选天然细胞因子混合物与胸腺肽联合施用。
