Olive pollen is one of the most important causes of respiratory allergy, with Ole e 1 being the most clinically relevant sensitizing allergen. Peptide-based vaccines represent promising therapeutic approaches, but the use of adjuvants is required to strengthen the weak immunogenicity of small peptides. We propose the use of dendrimeric scaffolds conjugated to the T cell immunodominant epitope of Ole e 1 (OE109-130) for the development of novel vaccines against olive pollen allergy. Four dendrimeric scaffolds containing an ester/ether with nine mannoses, an ester succinimidyl linker with nine N-acetyl-glucosamine units or nine ethylene glycol units conjugated to OE109-130 peptide were designed, and their cytotoxicity, internalization pattern, and immunomodulatory properties were analyzed in vitro. None of the dendrimers exhibited cytotoxicity in humanized rat basophil (RBL-2H3), human bronchial epithelial Calu-3, and human mast LAD2 cell lines. Confocal images indicated that mannosylated glycodendropeptides exhibited lower colocalization with a lysosomal marker. Moreover, mannosylated glycodendropeptides showed higher transport tendency through the epithelial barrier formed by Calu-3 cells cultured at the air-liquid interface. Finally, mannosylated glycodendropeptides promoted Treg and IL10+Treg proliferation and IL-10 secretion by peripheral blood mononuclear cells from allergic patients. Mannosylated dendrimers conjugated with OE109-130 peptide from Ole e 1 have been identified as suitable candidates for the development of novel vaccines of olive pollen allergy.

肽糖蛋白是橄榄花粉过敏的潜在疫苗。

橄榄花粉是呼吸道过敏的最重要原因之一,Ole e 1是临床上最相关的致敏过敏原。基于肽的疫苗代表了有希望的治疗方法,但是需要使用佐剂来增强小肽的弱免疫原性。我们建议使用与Ole e 1(OE109-130)的T细胞免疫优势表位缀合的树枝状支架来开发针对橄榄花粉过敏的新型疫苗。设计了四个包含酯/醚和九个甘露糖的树状支架,一个具有九个与OE109-130肽缀合的N-乙酰基-葡萄糖胺单元或九个乙二醇单元的酯琥珀酰亚胺基接头,并分析了它们的细胞毒性,内在化模式和免疫调节特性体外。在人源化大鼠嗜碱性粒细胞(RBL-2H3),人支气管上皮Calu-3和人肥大LAD2细胞系中,没有任何树状聚合物显示出细胞毒性。共聚焦图像表明,甘露糖基化糖链肽表现出较低的与溶酶体标记物的共定位。此外,甘露糖基化糖链肽显示出通过在气液界面培养的Calu-3细胞形成的上皮屏障的更高的运输趋势。最后,甘露糖基化糖链肽肽促进过敏患者外周血单核细胞的Treg和IL10 + Treg增殖以及IL-10分泌。与来自Ole e 1的OE109-130肽缀合的甘露糖基化的树枝状大分子已被确定为开发新型橄榄花粉过敏疫苗的合适候选者。和人类肥大LAD2细胞系。共聚焦图像表明,甘露糖基化糖链肽与溶酶体标记物的共定位性较低。此外,甘露糖基化糖链肽显示出通过在气液界面培养的Calu-3细胞形成的上皮屏障的更高的运输趋势。最后,甘露糖基化糖链肽肽促进过敏患者外周血单核细胞的Treg和IL10 + Treg增殖以及IL-10分泌。与来自Ole e 1的OE109-130肽缀合的甘露糖基化的树枝状大分子已被确定为开发新型橄榄花粉过敏疫苗的合适候选者。和人类肥大LAD2细胞系。共聚焦图像表明,甘露糖基化糖链肽表现出较低的与溶酶体标记物的共定位。此外,甘露糖基化糖链肽显示出通过在气液界面培养的Calu-3细胞形成的上皮屏障的更高的运输趋势。最后,甘露糖基化糖链肽肽促进过敏患者外周血单核细胞的Treg和IL10 + Treg增殖以及IL-10分泌。与来自Ole e 1的OE109-130肽缀合的甘露糖基化的树枝状大分子已被确定为开发新型橄榄花粉过敏疫苗的合适候选者。甘露糖基化糖链糖肽通过在气液界面培养的Calu-3细胞形成的上皮屏障显示出更高的转运趋势。最后,甘露糖基化糖链肽肽促进过敏患者外周血单核细胞的Treg和IL10 + Treg增殖以及IL-10分泌。与来自Ole e 1的OE109-130肽缀合的甘露糖基化的树枝状大分子已被确定为开发新型橄榄花粉过敏疫苗的合适候选者。甘露糖基化糖链糖肽通过在气液界面培养的Calu-3细胞形成的上皮屏障显示出更高的转运趋势。最后,甘露糖基化糖链肽肽促进过敏患者外周血单核细胞的Treg和IL10 + Treg增殖以及IL-10分泌。与来自Ole e 1的OE109-130肽缀合的甘露糖基化的树枝状大分子已被确定为开发新型橄榄花粉过敏疫苗的合适候选者。
