**作者**: Terry J. Hornick, Christopher D.M. Fletcher
**摘要**: 该研究通过免疫组化分析证实TLE1在滑膜肉瘤中高表达(敏感性>90%)，而在其他软组织肿瘤(如神经鞘瘤、孤立性纤维性肿瘤)中表达较低，提示TLE1可作为滑膜肉瘤的特异性诊断标志物。研究还讨论了TLE1在鉴别诊断中的应用价值。

**作者**: Kosemehmetoglu K, Folpe A.L.
**摘要**: 通过组织芯片技术评估TLE1在多种间叶源性肿瘤中的表达，发现其在滑膜肉瘤中高度敏感且特异(阳性率约95%)，但在部分恶性周围神经鞘瘤和上皮样肉瘤中偶见假阳性。研究强调需结合其他标志物(如EMA、CK)进行综合诊断。

**摘要**: 比较TLE1与SS18-SSX融合基因检测在滑膜肉瘤诊断中的效能。结果显示，TLE1免疫组化的敏感性与分子检测相当(约92%)，但特异性略低(约85%)。建议在高分化或疑难病例中联合使用TLE1与分子检测以提高准确性。

**Background of TLE1 Antibody**
The Transducin-Like Enhancer of Split 1 (TLE1) antibody is a diagnostic tool targeting the TLE1 protein, a member of the Groucho/TLE family of transcriptional corepressors. TLE1 regulates gene expression by interacting with transcription factors, notably inhibiting Wnt and Notch signaling pathways, and plays roles in cell differentiation, apoptosis, and embryonic development.
In clinical pathology, TLE1 gained prominence as an immunohistochemical (IHC) marker for synovial sarcoma, a soft-tissue malignancy. Overexpression of TLE1 in synovial sarcoma correlates with the SS18-SSX fusion gene, a hallmark genetic alteration. Nuclear positivity for TLE1 aids in distinguishing synovial sarcoma from histologic mimics like malignant peripheral nerve sheath tumors or solitary fibrous tumors. However, TLE1 expression is not entirely specific; it may occur in other tumors (e.g., endometrial stromal sarcoma) or non-neoplastic tissues.
Research applications extend to studying TLE1's role in cancer biology, particularly its involvement in oncogenic pathways and epigenetic regulation. Recent studies also explore its expression in non-small cell lung carcinoma subsets and neurological disorders. Despite its utility, TLE1 interpretation requires context with morphology and ancillary markers (e.g., SS18-SSX FISH) to enhance diagnostic accuracy. Its reliability and ease of use in IHC make TLE1 a valuable, though supplementary, tool in tumor classification and molecular research.
