概括

在成人T细胞白血病/淋巴瘤 (ATLL) 中,免疫球蛋白和免疫受体氨酸基抑制动机域 (TIGIT) 表达的T细胞免疫受体增加与较差的生存率有关. 这一发现强调了TIGIT作为ATLL患者潜在的预后标志物.

科学领域:

免疫学免疫学免疫学
在瘤学瘤学.
病理学病理学病理学

背景情况:

成人T细胞白血病/淋巴瘤 (ATLL) 是一种具有不良预后的侵袭性癌症.
具有免疫球蛋白和免疫受体氨酸基抑制动机域 (TIGIT) 的T细胞免疫受体是一种免疫检查点受体,与各种癌症有关.
目前,ATLL中TIGIT的预后意义尚不清楚.

研究的目的:

调查ATLL中TIGIT表达的临床病理影响.
为了确定TIGIT表达是否作为ATLL患者的预后标记.

主要方法:

用免疫组织化学检测ATLL患者样本中的TIGIT表达.
临床病理学数据和整体存活率与TIGIT表达相关分析.
进行单变量和多变量分析以评估预后价值.

主要成果:

在研究的84名患者中,在25%的患者中检测到TIGIT的表达.
观察到TIGIT表达与临床特征之间存在部分关联,包括sIL-2R,CD86和GITR.
与TIGIT阴性患者 (MST 18.7 个月) 相比,TIGIT阳性患者的整体存活率明显较低 (MST 8.9 个月).
在单变量和多变量分析中,TIGIT表达是总生存的独立预后因素.

结论:

TIGIT表达是成年T细胞白血病/淋巴瘤的显著负面预后标志物.
需要进一步的研究来阐明TIGIT在ATLL中的临床和生物作用.

Non-LTR Retrotransposons

Non-LTR Retrotransposons

As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
