概括

阿勒姆图祖马布有效地降低了 CD4 阳性 T 细胞和爱斯坦-巴尔病毒 DNA 在一个患有全身慢性活性 EBV 疾病的患者,接受全源干细胞移植. 这表明,阿勒姆图祖马布可能会在移植前加速EBV感染细胞的清除.

科学领域:

免疫学免疫学免疫学
血液学血液学血液学
病毒学病毒学

背景情况:

阿莱姆图祖马布向CD52,用于异源造血干细胞移植 (allo-HSCT) 中的移植与宿主疾病 (GVHD) 预防.
系统性慢性活跃的爱斯坦-巴尔病毒疾病 (sCAEBV) 涉及感染EBV的CD4阳性T细胞,在alo-HSCT中构成挑战.

研究的目的:

在 allo-HSCT 之前报告一个用基于 alemtuzumab 的 GVHD 预防治疗的 sCAEBV 病例.
评估阿勒姆图祖马布在减少EBV感染细胞的疗效及其对GVHD预防的影响.

主要方法:

一名26岁的患有sCAEBV的妇女在allo-HSCT之前从HLA匹配的兄弟姐妹那里接受了阿勒姆图祖马布 (0.16毫克/公斤).
流细胞计监测了表达CD52的CD4阳性T细胞和EBV-DNA负载.
标准的调节方案和移植后的免疫抑制进行了管理.

主要成果:

阿勒姆图祖马布的使用导致CD4阳性T细胞的快速下降和无法检测的EBV-DNA水平.
该患者成功接受了allo-HSCT,没有GVHD或严重感染.
移植时阿勒姆图祖马布的血清度为0.36μg/mL.

结论:

在 allo-HSCT 之前,早期的阿勒姆图祖马布治疗可能会在 sCAEBV 患者中增强 EBV 感染细胞的消除.
这种方法可能会减少长期的移植后免疫抑制.
阿勒姆图祖马布在接受allo-HSCT的sCAEBV患者中作为GVHD预防的一部分显示出希望.

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...

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.
