概括

新的研究表明,支持解决问题的调解者可以准休眠的乳腺癌细胞及其支持位,防止复发. 这为转移性乳腺癌 (BC) 提供了一种潜在的新疗法,该疗法抵抗常规治疗.

科学领域:

在瘤学瘤学.
免疫学免疫学免疫学
细胞生物学细胞生物学

背景情况:

转移性乳腺癌 (BC) 可能从耐治疗的静止扩散瘤细胞 (QDTC) 复发.
富含I型原蛋白 (Col-I) 的纤维状 (FLN) 支持QDTC外生.
目前的疗法无法消除QDTC,留下了一个关键的未满足的需求.

研究的目的:

调查巨细胞中的亲解决媒介是否可以防止FLN形成和QDTC外生.
确定这些调解者是否可以针对QDTC及其利基市场,以防止BC复发.

主要方法:

The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Metastasis

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
