概括

我们开发了一种新的纳米粒子系统,以耗尽瘤中髓状原型抑制细胞 (MDSC). 这种方法增强了T细胞的透,并提高了癌症免疫疗法的有效性,特别是免疫检查点阻塞 (ICB) 疗法.

科学领域:

免疫学免疫学免疫学
在瘤学瘤学.
纳米技术纳米技术

背景情况:

骨髓系衍生抑制细胞 (MDSCs) 是瘤微环境的关键调节者.
MDSCs可以抑制抗瘤免疫反应,并限制免疫检查点阻塞 (ICB) 治疗的疗效.

研究的目的:

开发一个有针对性的药物输送系统,以减少瘤内的MDSCs.
研究该系统在增强抗瘤免疫力和ICB治疗方面的潜力.

主要方法:

发展带有静态载荷的半孔二氧化纳米粒子 (PEG-MSN-Stattic).
将PEG-MSN-Stattic注射到瘤部位.
评估MDSC枯竭,T淋巴细胞透和ICB治疗的疗效.

主要成果:

PEG-MSN-静态有效耗尽了内MDSCs.
这种枯竭导致T淋巴细胞越来越多地入瘤微环境.
这种方法表明,有可能提高ICB治疗的疗效.

结论:

通过PEG-MSN-Stattic提供Stattic的向输送是调节瘤微环境的可行策略.
这种方法有望通过克服MDSC介导的抑制来改善癌症免疫治疗结果.

Tumor Immunotherapy

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Mesenchymal Stem Cells

Mesenchymal Stem Cells

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...
