Although other co-viral infections could also be considered influencing factors, cervical human papillomavirus (HPV) infection is the main cause of cervical cancer. Metagenomics have been employed in the NGS era to study the microbial community in each habitat. Thus, in this investigation, virome capture sequencing was used to examine the virome composition in the HPV-infected cervix. Based on the amount of HPV present in each sample, the results revealed that the cervical virome of HPV-infected individuals could be split into two categories: HPV-dominated (HD; ≥60%) and non-HPV-dominated (NHD; <60%). Cervical samples contained traces of several human viral species, including the molluscum contagiosum virus (MCV), human herpesvirus 4 (HHV4), torque teno virus (TTV), and influenza A virus. When compared to the HD group, the NHD group had a higher abundance of several viruses. Human viral diversity appears to be influenced by HPV dominance. This is the first proof that the diversity of human viruses in the cervix is impacted by HPV abundance. However, more research is required to determine whether human viral variety and the emergence of cancer are related.
虽然其他共感染病毒也可能被认为是影响因素,但宫颈人乳头瘤病毒(HPV)感染是宫颈癌的主要原因。宏基因组学已在 NGS 时代被用于研究每个栖息地的微生物群落。因此,在这项研究中,采用病毒组捕获测序来检测 HPV 感染宫颈中的病毒组组成。根据每个样本中 HPV 的数量,结果表明 HPV 感染个体的宫颈病毒组可以分为两类:HPV 占主导地位(HD;≥60%)和非 HPV 占主导地位(NHD;<60%)。宫颈样本中存在多种人类病毒的痕迹,包括传染性软疣病毒(MCV)、人类疱疹病毒 4(HHV4)、扭转型肠病毒(TTV)和甲型流感病毒。与 HD 组相比,NHD 组有几种病毒的丰度更高。人类病毒多样性似乎受到 HPV 优势的影响。这首次证明 HPV 丰度会影响宫颈中人类病毒的多样性。然而,需要进一步的研究来确定人类病毒多样性和癌症的发生是否有关。
