Objective
最近的研究揭示了立方体的佐剂活性及其作为抗原传递系统的潜在用途。为了进一步提高立方体的佐剂活性,本研究在立方体表面修饰了两种阳离子聚合物。 Methods本文通过在灵芝多糖立方体(GLPC)表面放置十六烷基三甲基溴化铵(CTAB)和聚二烯丙基二甲基氯化铵(PDDAC)两种分子,研究了表面化学对其佐剂活性的影响。 ResultsCTAB-或PDDAC修饰的GLPC可显著促进体液和细胞免疫应答,并通过树突状细胞(dc)的强烈激活促进CD3+CD4+或CD3+CD8+T细胞的增殖。PDDAC修饰的GLPC增强的免疫应答可能与DCs向引流淋巴结的成熟、脾脏和血清细胞因子的活化有关。 ConclusionPDDAC修饰有利于增强体液和细胞免疫应答,提示PDDAC-GLPC-OVA有可能成为疫苗的潜在佐剂。 |

Objective
Recent studies have revealed the adjuvant activity of cubosomes and their potential utility as an antigen delivery system. In this study, to further enhance the adjuvant activity of cubosomes, two cationic polymers are modified on the surface of cubosomes. MethodsHere, we exploit the effects of surface chemistry on the adjuvant activity of Ganoderma lucidum polysaccharide cubosomes (GLPC) by placing two kinds of molecules, that is, cetyltrimethylammonium bromide (CTAB) and poly(diallydimethyl ammonium chloride) (PDDAC), on their surface. ResultsCTAB- or PDDAC-modified GLPC were found to significantly promote humoral and cellular immune responses, as well as the proliferation of CD3+ CD4+ or CD3+ CD8+T cells through the powerful activation of dendritic cells (DCs). The enhanced immune responses of PDDAC-modified GLPC might be attributed to the maturation of DCs into draining lymph nodes and the activation of spleen and cytokines in serum. ConclusionPDDAC modification is beneficial for enhancing humoral and cellular immune response, suggesting that PDDAC-GLPC-OVA has the ability to be a potential adjuvant for vaccine. |
