Minimal deviation adenocarcinoma (MDA) of the uterine cervix, also referred to as malignant adenoma, is a rare subtype of cervical adenocarcinoma that exhibits histological characteristics resembling those of benign tumors, resulting in a low diagnostic rate and a lack of effective treatment options. The transcriptomic features of MDA at the single-cell resolution and within the tumor microenvironment (TME) remain unclear. In this study, we conducted single-cell transcriptomic analyses of MDA samples (Ca) and adjacent normal tissues (PCa). The present study reveals the prevalence of dendritic cells (DCs) and T cells in the carcinoma (Ca) of mammary ductal adenocarcinoma (MDA), with DCs undergoing significant metabolic reprogramming and immune stress. Additionally, our findings demonstrate the crucial involvement of DCs and T cells in the pathogenesis and metastatic progression of MDA, as evidenced by single-cell transcriptomic profiling of MDA and HPV samples. This resource provides a more profound understanding of the indolent nature of MDA and may prove useful in the development of MDA immunotherapy.
子宫颈微小偏离性腺癌(MDA),也称为恶性腺瘤,是宫颈腺癌的一种罕见亚型,其组织学特征类似于良性肿瘤,导致诊断率低且缺乏有效的治疗选择。MDA在单细胞分辨率和肿瘤微环境(TME)中的转录组特征仍不清楚。在本研究中,我们对MDA样本(Ca)和相邻正常组织(PCa)进行了单细胞转录组分析。本研究揭示了树突状细胞(DCs)和T细胞在乳腺导管腺癌(MDA)的癌组织(Ca)中的普遍性,其中DCs经历了显著的代谢重编程和免疫应激。此外,我们的研究结果表明,DCs和T细胞在MDA的发病机制和转移进展中起关键作用,MDA和HPV样本的单细胞转录组分析证明了这一点。该资源为深入了解MDA的惰性本质提供了更多信息,并可能在MDA免疫治疗的开发中证明有用。
