# Protocol for immunodetection of α-synuclein pathology in paraffin-embedded liver tissues from murine models of Parkinson’s disease

## TL;DR

This paper provides a detailed protocol for detecting α-synuclein pathology in mouse liver tissues, which could help understand Parkinson’s disease progression.

## Contribution

A novel protocol for immunodetecting α-synuclein in paraffin-embedded murine liver tissue using fluorescence microscopy.

## Key findings

- The protocol enables detection of both total and modified α-synuclein in liver tissues.
- The method can be adapted for use in human liver tissue studies.
- The approach supports investigations into the liver’s role in α-synuclein clearance in Parkinson’s disease.

## Abstract

The accumulation of α-synuclein (α-Syn) pathology in peripheral tissues of Parkinson’s disease (PD) has attracted growing scientific interest in recent years. Here, we present a protocol for the immunodetection of α-Syn pathology in murine liver tissue from models of PD using fluorescence microscopy. We describe steps for liver isolation, fixation, embedding, and immunodetection using an array of antibodies targeting α-Syn. This approach offers valuable applications for studying PD in transgenic mouse models and could be adapted for human liver tissue.
