概括
大多数扩散性大B细胞淋巴瘤 (DLBCL) 风险因素并没有因细胞起源 (COO) 而有所不同. 然而,酒精使用,社会经济地位 (SES) 和阿司匹林使用与DLBCL亚型有明显的关联.
科学领域:
- 在瘤学瘤学.
- 血液学 血液学 血液学
- 流行病学 流行病学
背景情况:
- 扩散性大B细胞淋巴瘤 (DLBCL) 是一种异构的淋巴状恶性瘤.
- 基因表达特征识别基于来源细胞 (COO) 的独特DLBCL亚型:生殖中心B细胞 (GCB) 和激活B细胞 (ABC).
研究的目的:
- 根据COO调查DLBCL风险因素的潜在病因异质性.

Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
Differentiation of Common Myeloid Progenitor Cells
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
