概括
乳腺癌患者接种SARS-CoV-2疫苗会产生强大的抗体和T细胞记忆反应. 一些患者可能缺乏抗原特异性T细胞,这表明尽管抗体水平高,但可能存在敏感性.
科学领域:
- 免疫学 免疫学 免疫学
- 在瘤学瘤学.
- 疫苗学 疫苗学 疫苗学
背景情况:
- 癌症患者的免疫力受损,需要了解疫苗反应.
- 在接受治疗的乳腺癌患者中评估SARS-CoV-2疫苗免疫性至关重要.
研究的目的:
- 评估乳腺癌患者对SARS-CoV-2疫苗接种的幽默和细胞免疫反应.
- 为了将免疫反应与临床结果相关联,并探索微生物群的关联.
主要方法:
- 对23名乳腺癌患者进行前性观察性研究.
- 分析IgG抗体水平,B细胞计数和T细胞表型 (原始,记忆,TEMRA) 在基线,第二剂后和增强剂后.
- 使用MHC I Dextramer试剂对抗原特异性CD8+ T细胞反应的评估.
- 使用sPLS-DA.微生物群的概况.
主要成果:
- 接种疫苗后IgG抗体和CD19+B细胞显著增加.
- 转向记忆T细胞表型,包括CD8+TEMRA细胞的扩张.
- 55.5%的患者在增强后发展出抗原特异性CD8+T细胞;一个没有这种反应的患者患有轻微的SARS-CoV-2感染.
- 显著的微生物特征 (例如,Alistipes, Romoutsia) 与高抗体反应相关.
结论:
- 在接受治疗的乳腺癌患者中,SARS-CoV-2疫苗接种具有免疫性和耐受性.
- 抗原特异性CD8+T细胞反应和抗体水平是互补的,但与免疫标记物没有直接关联.
- 微生物群与免疫相互作用需要进一步研究,以优化瘤学中的疫苗接种策略.

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
