三、作用机制

免疫激活双通路

1、固有免疫激活:

温和皂苷水佐剂提取自南美皂树 (Quillaja saponaria Molina)的水溶性皂苷成分,属于三萜皂苷类化合物,具有共同的三萜骨架结构。该皂苷能对T细胞依赖性与非依赖性抗原均产生强效佐剂效应,并可显著增强CD8+细胞毒性淋巴细胞反应,提升黏膜抗原免疫应答。

温和皂苷水佐剂能增强免疫器官中免疫细胞的分化和增殖能力,通过增加天然免疫细胞的数量,促进天然免疫细胞的分化和成熟,降低免疫抑制分子的表达,促进免疫效应细胞增殖,从而发挥其免疫增强效应。同时温和皂苷水佐剂与抗原通过胞吞作用方式进入抗原递呈细胞, 在温和皂苷水佐剂介导的内体膜破坏后,裂解的蛋白质抗原可以通过蛋白酶体机制在胞质溶胶中进一步加工成更小的肽片段。降解的肽通过转运蛋白分子易位到内质网中,在内质网中促进它们与新合成的MHC-I分子结合,从而通过高尔基体囊泡迁移到细胞表面。最后,与 MHC-I分子相关的暴露在DC (树突状细胞)表面上的肽表位通过T细胞受体呈递给幼稚的 CD8+T细胞 (交叉呈递)。提供共刺激信号,分泌细胞因子,引起免疫应答。

I. Product Positioning

Core Characteristics

Mild Saponin Aqueous Adjuvant is a highly purified, concentrated saponin adjuvant that can also serve as a universal immune enhancer. It appears as a pale yellow or amber clear transparent liquid, with highly purified immunologically active substances as the main component and a pH value of 4.0–6.5. It is safe, non-toxic and metabolizable, effectively induces immune responses in the body, exhibits strong immune effects against both T-cell-dependent and T-cell-independent antigens, and produces a remarkable mucosal immune response.

Technical Breakthroughs

1. Raw Material Innovation: Through raw material screening, a standardized raw material grading system has been established, with batch-to-batch consistency CV < 3%.

2. Process Upgrading: A new technical route for saponin production is adopted, resulting in higher saponin purity and a 50% cost reduction compared with imported products.

III. Mechanism of Action

Dual Pathway Immune Activation

1. Innate Immune Activation

Mild Saponin Aqueous Adjuvant is derived from the water-soluble saponin fraction of Quillaja saponaria Molina, belonging to triterpenoid saponins with a common triterpene skeleton structure. It exerts potent adjuvant effects on both T-cell-dependent and T-cell-independent antigens, significantly enhances CD8⁺ cytotoxic lymphocyte responses, and boosts mucosal antigen immune responses.

Mild Saponin Aqueous Adjuvant enhances the differentiation and proliferation of immune cells in immune organs. By increasing the number of innate immune cells, promoting their differentiation and maturation, reducing the expression of immunosuppressive molecules, and stimulating the proliferation of immune effector cells, it exerts an immune-enhancing effect. Meanwhile, the adjuvant and antigen enter antigen-presenting cells via endocytosis. Following endosomal membrane disruption mediated by the adjuvant, the degraded protein antigens are further processed into smaller peptide fragments in the cytosol through the proteasome pathway. The degraded peptides are translocated into the endoplasmic reticulum via transporter molecules, where they facilitate binding to newly synthesized MHC class I molecules, which then migrate to the cell surface via Golgi vesicles. Finally, peptide epitopes associated with MHC class I molecules exposed on the surface of DCs (dendritic cells) are presented to naive CD8⁺ T cells via the T-cell receptor (cross-presentation), providing co-stimulatory signals, secreting cytokines, and triggering an immune response.

Safety Advantages

1. Low-Toxicity Design: Highly allergenic impurities such as polysaccharides, polyphenols and tannins are removed (removal rate ≥95%).

2. Acute oral toxicity in rats: LD₅₀ > 5000 mg/kg b.w., EPA Toxicity Category IV.

3. Acute dermal toxicity in rats: LD₅₀ > 4000 mg/kg b.w.
