Antrodia camphorata (AC) is a commonly used fungus in folk medicine for the treatment of viral hepatitis and cancer. AC polysaccharides (AC-PS) are reported to possess anti-inflammatory, anti-hepatitis B virus, and anticancer activities. In this study, we tested the in vivo effect of AC-PS on immune function by evaluating cytokine expression; on immunomodulation, by evaluating spleen cells; and on Schistosoma mansoni infection in mice. The induction of high levels of interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha (TNF-alpha) mRNA was detected in BALB/c mice after 2, 4, and 6 weeks of oral AC-PS administration. After 6 weeks of oral AC-PS administration to the BALB/c mice, the number of splenic dendritic cells, macrophages, and the surface expression of CD8 alpha+ and major histocompatibility class II I-A/I-E on dendritic cells increased. The CD4+/CD8+ ratio and number of B cells among splenocytes were also augmented. By using a disease model of parasitic infection, we found that AC-PS treatment inhibited S. mansoni infection in BALB/c mice. AC-PS appears to modulate the immune system of mice and has potential for preventing S. mansoni infection.
樟芝是一种民间医学中常用于治疗病毒性肝炎和癌症的真菌。据报道,樟芝多糖(AC-PS)具有抗炎、抗乙肝病毒和抗癌活性。在本研究中,我们通过评估细胞因子表达来测试AC-PS对免疫功能的体内作用;通过评估脾细胞来测试其对免疫调节的作用;并测试其对小鼠曼氏血吸虫感染的影响。在BALB/c小鼠口服AC-PS 2、4和6周后,检测到高水平的干扰素-γ(IFN-γ)和肿瘤坏死因子-α(TNF-α)mRNA的诱导。在BALB/c小鼠口服AC-PS 6周后,脾树突状细胞、巨噬细胞的数量以及树突状细胞上CD8α+和主要组织相容性复合体II类I-A/I-E的表面表达增加。脾细胞中B细胞的CD4+/CD8+比值和数量也增加。通过使用寄生虫感染疾病模型,我们发现AC-PS治疗可抑制BALB/c小鼠的曼氏血吸虫感染。AC-PS似乎可调节小鼠的免疫系统,并具有预防曼氏血吸虫感染的潜力。
