概括

这项研究介绍了一种使用DSPE-PEG2k的"粘"策略,以创建用于向化疗的有效细胞膜伪装纳米颗粒. 这些纳米颗粒显示出改善瘤积累和强大的抗癌效应,降低了毒性.

科学领域:

生物医学工程生物医学工程
纳米技术纳米技术
药物运输药物运输药物运输

背景情况:

同位体原药纳米组件 (HDPN) 提高了化疗药物选择性,但缺乏有效的瘤向.
细胞膜伪装的纳米粒子 (CM-NP) 通过同源向增强瘤积累.
在制备CM伪装的HDPN方面存在挑战,原因是疏水性-疏水性亲和力较差.

研究的目的:

开发一种方法来制备细胞膜伪装的同质原药纳米组件 (CM-HDPN),以增强瘤向.
研究DSPE-PEG2k作为"粘合剂"的作用,以改善HDPN与癌细胞膜 (CM) 之间的亲和力.
评估CM量对CM-HDPN的性能和治疗疗效的影响.

主要方法:

使用DSPE-PEG2k作为两性链接器,以增强帕克利塔塞尔 (PTX) HDPN与CM之间的亲和力.
优化了CM量,以达到1:0.25的药物-膜重量比,以获得稳定的CM-HDPN制剂.
在体内评估瘤积累,细胞内化,药物释放和抗瘤疗效.

主要成果:

添加20%的DSPE-PEG2k显著改善了HDPN和CM之间的亲和力.
稳定的CM-HDPN在优化的CM负载下成功准备.
CM-HDPNs表现出增强的同源向,导致高瘤积累和快速内化.
在瘤微环境中释放的反氧反应性PTX产生了强大的抗瘤活性,毒性最小.

结论:

DSPE-PEG2k"粘合"策略有效地克服了准备CM伪装HDPN的挑战.
与非伪装的HDPN相比,CM-HDPN显示出优越的瘤向性和治疗疗效.
这种方法为开发针对癌症化学疗法的先进纳米配方提供了一个有希望的平台.

Targeted Cancer Therapies

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Treatment Resistant Cancers

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
