探讨树突状细胞(DC)与细胞因子诱导的杀伤细胞(CIK)共培养对前列腺癌(PCa)细胞的免疫效果。从健康献血者外周血中提取外周血单个核细胞(PBMCs),诱导并共培养DC和CIK细胞,观察DC、CIK及DC-CIK细胞/组的增殖和表型变化。通过向腹腔注射PC3 PCa细胞构建模型大鼠,将成功的50例分为阴性对照组、化疗组、DC组、CIK组和DC-CIK治疗组(每组10只),观察肿瘤进展。DC-CIK组白细胞介素-12(IL-12)((103.67 ± 2.77) pg/mL)和干扰素-γ(IFN-γ)((730.09 ± 23.52) pg/mL)的分泌浓度高于DC组和CIK组;在培养12至20天内,DC-CIK组中CIK的增殖高于CIK组。
DC-CIK组CD3 + / CD56 + 和CD8 + 的阳性率(PR)高于CIK组,而CD45RA + 的阳性率低于CIK组。在靶效比为10:1/20:1/50:1时,DC-CIK组的杀伤率高于DC组和CIK组(P < 0.05)。治疗后,化疗组、DC组和CIK组大鼠体重显著降低(P < 0.05),而阴性对照组和DC-CIK组未见显著变化(P > 0.05)。治疗25天后,DC-CIK组肿瘤大小显著小于阴性对照组、化疗组、DC组和CIK组;DC-CIK组肿瘤组织坏死面积也显著大于阴性对照组、化疗组、DC组和CIK组(P < 0.05)。DC与CIK共培养能显著促进CIK细胞增殖,增加IL-12和IFN-γ分泌,增强免疫细胞活性及抗肿瘤能力,在抗PCa肿瘤免疫治疗中显示出潜力。
It was to explore the immune outcome of co-culture of dendritic cells (DC) and cytokine-induced killer cells (CIK) on prostate cancer (PCa) cells. Peripheral blood mononuclear cells (PBMCs) were extracted from healthy blood donors. DC and CIK cells were induced and co-cultured. The proliferation and phenotypic changes of DC, CIK, and DC-CIK cells/groups were observed. Model rats were constructed by injecting PC3 PCa cells into the abdominal cavity. The successful 50 cases were divided into a negative control group, a chemotherapy group, a DC group, a CIK group, and a DC-CIK treatment group (each consisting of 10 rats) to observe tumor progression. The secreted concentrations of interleukin-12 (IL-12) ((103. 67 ± 2. 77) pg/mL) and interferon-γ (IFN-γ) ((730. 09 ± 23. 52) pg/mL) were higher in DC-CIK group as against DC and CIK groups; the proliferation of CIK was higher in DC-CIK group as against CIK within 12 to 20 days of culture. The positive rate (PR) of CD3 + / CD56 + and CD8 + was higher and that of CD45RA + was lower in DC-CIK group as against CIK.
The killing rate of the DC-CIK group was higher than that of the DC and CIK groups at a target effect ratio of 10:1/20:1/50:1 (P < 0. 05). After the treatment, the body weight of rats in the chemotherapy group, DC group, and CIK group was significantly reduced (P < 0. 05), while no significant changes were observed in the negative control group and DC-CIK group (P > 0. 05).
After 25 days of treatment, the tumor size in the DC-CIK group was significantly smaller compared to the negative control group, chemotherapy group, DC group, and CIK group; the necrotic area of the tumor tissue in the DC-CIK group was also significantly larger than that in the negative control group, chemotherapy group, DC group, and CIK group (P < 0.
05). Co-culture of DC and CIK is excellent in enhancing the proliferation of CIK cells, increasing the secretion of IL-12 and IFN-γ, and enhancing the activity of immune cells and anti-tumor ability, showing its potential in anti-PCa tumor immunotherapy.
