项目摘要

Abstract Angioimmunoblastic T-cell lymphoma (AITL) is a rare and aggressive type of peripheral T-cell lymphoma. The majority of patients with AITL are diagnosed at an advanced stage, and have poor prognosis, even with aggressive chemotherapies. Because there has been no improvement in the survival rate of AITL patients over the past two decades ever since the disease was first characterized, there is an urgent need for the discovery and development of an effective treatment. A novel therapeutic target for AITL is the CXCR5-CXCL13 signaling axis, which plays a prominent role in AITL lymphomagenesis, proliferation, and metastasis. By antagonizing CXCR5, Dr. Lolis (PhD, Professor of Pharmacology) and Dr. Foss (MD, Professor of Medicine and of Dermatology) are developing novel therapeutics to treat AITL. They have identified a promising CXCR5 antagonist with decent potency, toxicity profile, and pharmacokinetics for clinical trial in AITL patients. This project is to develop a CXCR5-specific Positron Emission Tomography (PET) imaging probe to explore the pharmacokinetics and pharmacodynamics of the experimental drug. Our research team comprises investigators from Yale PET Center and Yale Cancer Center, and will harness the unique research resources in these centers. Successful completion of this project will set the stage for the clinical trial of the experimental CXCR5 antagonist in AITL patients with the right dose range. Furthermore, as CXCR5 is overexpressed in other types of cancers, i.e., B-cell lymphoma, other T follicular helper cell-mediated lymphomas, prostate cancer, breast cancer, colon cancer, and non-small cell lung carcinoma, the CXCR5 PET imaging probe will also be instrumental in the study of these human diseases.

抽象的血管免疫母细胞 T 细胞淋巴瘤 (AITL) 是一种罕见且具有侵袭性的外周 T 细胞淋巴瘤。大多数 AITL 患者确诊时已属晚期，即使已确诊，预后也较差积极的化疗。因为AITL患者的生存率并没有改善自从该疾病首次被定性以来的过去二十年里，迫切需要发现这一疾病并开发有效的治疗方法。 AITL 的一个新治疗靶点是 CXCR5-CXCL13 信号轴，在 AITL 淋巴瘤发生、增殖和转移中发挥重要作用。经过 Lolis 博士（药理学教授）和 Foss 博士（医学博士，医学教授）拮抗 CXCR5 和皮肤科）正在开发治疗 AITL 的新疗法。他们发现了一种有前途的 CXCR5 具有良好效力、毒性特征和药代动力学的拮抗剂，可用于 AITL 患者的临床试验。这该项目是开发一种CXCR5特异性正电子发射断层扫描（PET）成像探针来探索实验药物的药代动力学和药效学。我们的研究团队包括来自耶鲁PET中心和耶鲁癌症中心的研究人员，并将利用独特的研究资源在这些中心。该项目的成功完成将为该实验的临床试验奠定基础 AITL患者中CXCR5拮抗剂的剂量范围合适。此外，由于 CXCR5 在其他类型的癌症，即 B 细胞淋巴瘤、其他滤泡辅助性 T 细胞介导的淋巴瘤、前列腺癌 CXCR5 PET 成像探针可用于癌症、乳腺癌、结肠癌和非小细胞肺癌也有助于研究这些人类疾病。
