Abstract

Sodium influx induced by hepatitis B virus (HBV) enhances activation of the NLRP3 inflammasome, in synergy with potassium efflux signals in macrophages. Here, we present a protocol for conducting patch-clamp assays to measure HBV-mediated sodium influx in THP-1 macrophages. We describe steps for differentiating, resting, and activating THP-1 macrophages and then outline the procedures for whole-cell patch-clamp recordings. For complete details on the use and execution of this protocol, please refer to Wang et al.1.

THP-1巨噬细胞中hbv介导的钠内流的全细胞膜片钳试验方案
乙型肝炎病毒(HBV)诱导的钠内流增强了NLRP3炎性体的激活,与巨噬细胞中的钾外排信号协同作用。在这里,我们提出了一种进行膜片钳试验的方案,以测量hbv介导的THP-1巨噬细胞中的钠内流。我们描述了分化、静息和激活THP-1巨噬细胞的步骤,然后概述了全细胞膜片钳记录的程序。有关本协议使用和执行的完整细节,请参考Wang等人1。
