研究概要

本研究表明,Pola 治疗改变了肿瘤中 M 细胞和 NK 细胞的浸润,凸显了这些固有免疫细胞对 Pola 抗肿瘤活性的重要贡献。

中文摘要

在DB(DLBCL细胞系)异种移植模型中,Pola诱导巨噬细胞和自然杀伤(NK)细胞浸润,并参与其抗肿瘤作用。此外,Pola诱导DB细胞释放多种损伤相关分子模式,并在离体共培养条件下增强免疫细胞迁移。同系小鼠模型也证实先天免疫细胞参与Pola的作用。

本研究表明,Pola治疗可改变肿瘤中巨噬细胞和NK细胞的浸润,凸显这些先天免疫细胞对Pola抗肿瘤活性的关键贡献。 试验注册:作者确认本稿件无需进行临床试验注册。

展开英文摘要原文

In the DB (DLBCL cell line) xenograft model, Pola induced infiltration of macrophages and natural killer cells, which contributed to the antitumor effect of Pola. Moreover, Pola induced the release of several damage-associated molecular patterns from DB cells and enhanced the migration of immune cells under ex vivo co-culture conditions. A syngeneic mouse model also confirmed the involvement of innate immune cells in the Pola effect.

This study demonstrates that Pola treatment alters M and NK cell infiltration in tumors, highlighting these innate immune cells' essential contribution to Pola's antitumor activity. TRIAL REGISTRATION: The authors have confirmed clinical trial registration is not needed for this submission.
