以下是3篇关于TNNT2抗体的代表性文献摘要整理：
1. **文献名称**：*Autoantibodies against cardiac troponin T in patients with dilated cardiomyopathy*
**作者**：Caforio AL, et al.
**摘要**：本研究检测了扩张型心肌病(DCM)患者血清中抗心肌肌钙蛋白T(cTnT)的自身抗体，发现约30%患者存在IgG型抗TNNT2抗体。抗体阳性与心室功能恶化相关，提示其可能参与DCM的免疫病理机制。
2. **文献名称**：*High-sensitivity cardiac troponin T in early diagnosis of acute myocardial infarction*
**作者**：Reichlin T, et al.
**摘要**：研究评估了高灵敏度TNNT2抗体检测试剂在早期急性心肌梗死(AMI)诊断中的价值。结果显示，采用新型单克隆TNNT2抗体的检测方法较传统方法显著提高AMI诊断灵敏度(94% vs 78%)，尤其对症状发作3小时内患者更具临床意义。
3. **文献名称**：*TNNT2 mutations and aberrant splicing in familial hypertrophic cardiomyopathy*
**作者**：Mogensen J, et al.
**摘要**：通过免疫印迹和免疫组化分析携带TNNT2基因突变的肥厚型心肌病(HCM)家系，发现突变导致心肌细胞中肌钙蛋白T亚型比例异常。研究使用特异性TNNT2抗体证实突变引起肌丝钙敏感性改变，为基因型-表型关联提供分子证据。

The TNNT2 antibody targets cardiac troponin T (cTnT), a key regulatory protein within the cardiac troponin complex located on the thin filaments of striated muscle. This complex, comprising troponin T, I, and C, plays a central role in calcium-dependent regulation of myocardial contraction. TNNT2. encoded by the *TNNT2* gene, is expressed predominantly in cardiac tissue and exists as multiple isoforms due to alternative splicing. Antibodies against TNNT2 are critical tools in cardiovascular research and diagnostics, enabling the detection and quantification of cTnT in both experimental and clinical settings.
In research, TNNT2 antibodies are widely used to study cardiac development, contractile function, and disease mechanisms. Mutations in *TNNT2* are linked to inherited cardiomyopathies, such as hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM), making these antibodies valuable for investigating genotype-phenotype correlations. Clinically, cTnT is a gold-standard biomarker for myocardial injury, and anti-TNNT2 antibodies form the basis of immunoassays to diagnose acute myocardial infarction (AMI). These assays detect elevated cTnT levels in blood, reflecting cardiomyocyte damage.
TNNT2 antibodies are also employed in techniques like immunohistochemistry, Western blotting, and ELISA to assess protein expression, localization, and post-translational modifications. Their specificity ensures minimal cross-reactivity with skeletal muscle troponin T isoforms, enhancing diagnostic accuracy. Ongoing studies explore their utility in monitoring cardiotoxicity from chemotherapeutic agents and understanding heart failure pathophysiology. Overall, TNNT2 antibodies bridge basic science and clinical practice, advancing both mechanistic insights and patient care.
