This study aimed to evaluate the immunomodulatory effect of the polysaccharide from (SCP-1-1) in RAW264.7 cells. SCP-1-1 with a molecular weight of 440.0 kDa consisted of glucose and mannose. The immunomodulatory assay results showed that SCP-1-1 could significantly enhance phagocytic ability, NO production, and some cytokines (TNF-α, IL-6, and IL-1β) secretion of RAW264.7 cell in a dose-dependent manner. Western blot analysis results demonstrated that SCP-1-1 could regulate the expression levels of the key proteins in the signaling pathways of RAW264.7 cell and might associated with NF-κβ and PI3K signaling pathway. These findings could contribute to elucidate the immunomodulatory activities of the polysaccharide from .
本研究旨在评估[具体来源]的多糖（SCP-1-1）对RAW264.7细胞的免疫调节作用。分子量为440.0 kDa的SCP-1-1由葡萄糖和甘露糖组成。免疫调节测定结果表明，SCP-1-1能以剂量依赖性方式显著增强RAW264.7细胞的吞噬能力、一氧化氮（NO）生成以及某些细胞因子（肿瘤坏死因子-α、白细胞介素-6和白细胞介素-1β）的分泌。蛋白质免疫印迹分析结果表明，SCP-1-1可调节RAW264.7细胞信号通路中关键蛋白的表达水平，可能与核因子κB（NF-κβ）和磷脂酰肌醇-3激酶（PI3K）信号通路有关。这些发现有助于阐明[具体来源]多糖的免疫调节活性。
