概括

人类端粒酶逆转录酶 (hTERT) 免疫表达在B细胞慢性淋巴细胞白血病 (B-CLL) 骨髓淋巴细胞中明显高于良性淋巴细胞. 需要进一步的研究来确定hTERT是否可以预测B-CLL患者的预后.

科学领域:

在瘤学瘤学.
血液学血液学血液学
细胞生物学细胞生物学

背景情况:

人类端粒酶逆转录酶 (hTERT) 在正常的原始细胞,瘤细胞和B细胞慢性淋巴细胞白血病 (B-CLL) 细胞中表达.
hTERT表达是B-CLL的潜在预后因素,与较差的结果有关.

研究的目的:

分析和比较hTERT免疫表达在B-CLL骨髓 (BM) 淋巴细胞和良性流淋巴细胞.
调查B-CLL和反应性淋巴细胞之间hTERT核染色模式的潜在差异.

主要方法:

标准细胞学分析和hTERT免疫表达的免疫细胞化学评估.
分析了来自25名B-CLL患者的BM淋巴细胞和来自18名反应性淋巴细胞症患者的多流淋巴细胞.

主要成果:

与良性输液淋巴细胞相比,在B-CLL患者中观察到hTERT核 (TN) 免疫阳性BM淋巴细胞的显著更高的百分比和得分值.
在B-CLL淋巴细胞中TN免疫阳性呈现为许多突出或大点和扩散染色.
良性输液淋巴细胞只显示了一个或几个TN免疫阳性核点.

结论:

淋巴细胞的hTERT免疫表达在B-CLL和良性反应性淋巴细胞之间有显著差异.
需要进一步调查,以确定TN淋巴细胞免疫阳性是否可以识别预后较差的B-CLL亚组,并确定可靠的诊断差异.

B Cell Activation and Differentiation

B Cell Activation and Differentiation

The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
