癌癥疫苗研發(fā)的新選擇 已有1人參與
|

poly-ICLC在臨床上多用于肽疫苗,DC疫苗和全細(xì)胞疫苗,主要用于多種癌癥疫苗的開發(fā),多個(gè)項(xiàng)目已進(jìn)入2期臨床。在癌癥疫苗中添加poly-ICLC可增強(qiáng)疫苗誘導(dǎo)的抗腫瘤T細(xì)胞和NK細(xì)胞反應(yīng),從而有助于腫瘤消退或根除。 然而,poly-ICLC 除了具有觸發(fā)強(qiáng)大免疫反應(yīng)的功能外,還可能具有劑量依賴性全身發(fā)熱和凝血異常等副作用。可喜的是,我國(guó)現(xiàn)在開發(fā)了安全高效的ε-poly-ICLC,為癌癥疫苗的開發(fā)提供了新的選擇。有意向的公司或?qū)嶒?yàn)室可私信 。 2025-10-19 |
| polyiclc的作用原理是模擬病毒,從而激活人的免疫系統(tǒng),本質(zhì)上是誘使身體認(rèn)為受到了攻擊。這會(huì)促使免疫系統(tǒng)產(chǎn)生強(qiáng)大的反應(yīng),包括激活自然殺傷細(xì)胞和b細(xì)胞等多種免疫細(xì)胞,以及產(chǎn)生干擾素和細(xì)胞因子等重要信號(hào)分子。 polyiclc在癌癥和傳染病市場(chǎng)擁有獨(dú)特的定位,可以為新的和已獲批的疫苗(包括樹突細(xì)胞疫苗)增加顯著的臨床價(jià)值,在復(fù)發(fā)性膠質(zhì)母細(xì)胞瘤和前列腺癌方面獲得的數(shù)據(jù)尤其令人興奮。 |
