Rising cases of Non melanoma skin carcinoma (NMSC) and escalating levels of ultraviolet radiations have underlined a profound correlation with the elevating levels of environmental detoriation and increasing health issues. However, the availability of therapeutics has not aided in controlling the recurrence rates of skin carcinoma. Frequent administration of therapeutics with higher chances of facial deformity escalates the patient's treatment expenses. Thus, this study initiates a low cost effective and biodegradable therapy by exploring four formulations with combinations of silver nanoparticles (AgNPs), sericin (isolated from cocoons of Antherea mylitta) and chitosan. Subsequently, various ethosomal formulations were evaluated as a platform for transdermal delivery vehicle for efficient skin intervention therapeutics. Characterization using UV visible spectroscopy, Dynamic light scattering, Fourier Infrared spectroscopy, X-ray dispersion, Transmission electron microscopy, Fluorescence assisted cell sorting and in vitro studies were done and it was inferenced that equal combination of AgNPs and sericin facilitated to combat the morphological and cellular deformation of the epidermoid A431skin carcinoma cells. The overproduction of superoxide (O and nitric oxide (NO) radicals consequently depolarized the mitochondrial membrane potential triggering apoptosis and necrosis. The in vivo experiments exhibited the stimulation of IgM secretion with T cell-mediated immune response. Therefore, this study proposes a novel approach for treatment of NMSC using biocompatible formulations delivered through ethosomes.
非黑色素瘤皮肤癌 (NMSC) 的病例不断增加,紫外线辐射水平不断上升,这与环境恶化程度的加深和健康问题的增加有很大的相关性。然而,治疗方法的可用性并没有帮助控制皮肤癌的复发率。频繁使用具有更高面部畸形风险的治疗方法会增加患者的治疗费用。因此,本研究通过探索四种含有银纳米粒子 (AgNPs)、丝胶(从家蚕茧中分离得到)和壳聚糖的组合的制剂,提出了一种低成本、有效的生物降解疗法。随后,我们评估了各种醇质体制剂作为经皮传递载体的平台,以实现高效的皮肤干预治疗。通过紫外可见光谱、动态光散射、傅里叶变换红外光谱、X 射线分散、透射电子显微镜、荧光辅助细胞分选和体外研究进行了表征,结果表明,AgNPs 和丝胶的等比例组合有助于对抗表皮样 A431 皮肤癌细胞的形态和细胞变形。超氧化物 (O 和一氧化氮 (NO) 自由基的过度产生导致线粒体膜电位去极化,从而触发细胞凋亡和坏死。体内实验显示,IgM 分泌得到刺激,伴有 T 细胞介导的免疫反应。因此,本研究提出了一种使用通过醇质体传递的生物相容性制剂治疗 NMSC 的新方法。
