Despite all precautionary actions and the possibility of using vaccinations to counteract infections caused by human papillomaviruses (HPVs), HPV-related cancers still account for approximately 5% of all carcinomas. Worldwide, many women are still excluded from adequate health care due to their social position and origin. Therefore, immense efforts in research and therapy are still required to counteract the challenges that this disease entails. The special thing about an HPV infection is that it is not only able to trick the immune system in a sophisticated way, but also, through genetic integration into the host genome, to use all the resources available to the host cells to complete the replication cycle of the virus without activating the alarm mechanisms of immune recognition and elimination. The mechanisms utilized by the virus are the metabolic, immune, and hormonal signaling pathways that it manipulates. Since the virus is dependent on replication enzymes of the host cells, it also intervenes in the cell cycle of the differentiating keratinocytes and shifts their terminal differentiation to the uppermost layers of the squamocolumnar transformation zone (TZ) of the cervix. The individual signaling pathways are closely related and equally important not only for the successful replication of the virus but also for the onset of cervical cancer. We will therefore analyze the effects of HPV infection on metabolic signaling, as well as changes in hormonal and immune signaling in the tumor and its microenvironment to understand how each level of signaling interacts to promote tumorigenesis of cervical cancer.
尽管采取了所有预防措施,并且有可能使用疫苗来对抗人乳头瘤病毒 (HPV) 感染,但 HPV 相关癌症仍约占所有癌的 5%。在全球范围内,由于社会地位和出身,许多女性仍然无法获得足够的医疗保健。因此,仍然需要在研究和治疗方面做出巨大努力,以应对这种疾病带来的挑战。HPV 感染的特殊之处在于,它不仅能够以复杂的方式欺骗免疫系统,而且还能够通过遗传整合到宿主基因组中,利用宿主细胞的所有可用资源来完成病毒的复制周期,而不会激活免疫识别和消除的警报机制。病毒利用的机制是其操纵的代谢、免疫和激素信号通路。由于病毒依赖于宿主细胞的复制酶,它还会干预分化角朊细胞的细胞周期,并将其终末分化转移到宫颈的鳞柱状转化区 (TZ) 的最上层。各个信号通路不仅对病毒的成功复制,而且对宫颈癌的发生都密切相关且同等重要。因此,我们将分析 HPV 感染对代谢信号的影响,以及肿瘤及其微环境中激素和免疫信号的变化,以了解每个信号水平如何相互作用以促进宫颈癌的肿瘤发生。
