Abstract:
Oxidized phosphatidylcholine (OxPC) found in multiple sclerosis brain lesions mediates neurodegeneration. Microglia are prominent responders to the OxPC insult, and thus, studying their protective or noxious functions is important to help halt neurodegeneration. Here, we present protocols including cell isolation and culture, animal surgeries, as well as tissue processing and isolation to study the microglia response to OxPC-mediated neurodegeneration in vitro and in vivo. For complete details on the use and execution of this protocol, please refer to Dong et al. (2021).
Insights
Oxidized phosphatidylcholine (OxPC) drives neurodegeneration in multiple sclerosis. This study details methods to investigate how microglia, key responders to OxPC, impact this process in vitro and in vivo.
Area of Science:
- Neuroscience
- Immunology
- Cell Biology
Background:
- Oxidized phosphatidylcholine (OxPC) is implicated in multiple sclerosis (MS) pathogenesis.
- OxPC accumulation in MS brain lesions contributes to neurodegeneration.
- Microglia are the primary immune cells in the brain and are key responders to OxPC.
Purpose of the Study:
- To present detailed protocols for studying microglia responses to OxPC.
- To investigate the role of microglia in OxPC-mediated neurodegeneration.
- To provide methods for both in vitro and in vivo investigations.
Main Methods:
- Cell isolation and culture techniques for microglia.
- Animal surgery protocols for experimental models.
- Tissue processing and sample isolation for analysis.
- In vitro and in vivo experimental setups to study OxPC effects.
Main Results:
- Established reproducible protocols for microglia isolation and culture.
- Developed methods for assessing microglia response to OxPC in vivo.
- Enabled detailed study of microglia's contribution to neurodegeneration.
Conclusions:
- The presented protocols facilitate the study of microglia's role in OxPC-induced neurodegeneration.
- Understanding microglia-OxPC interactions is crucial for developing MS therapies.
- These methods support further research into neuroprotective or neurotoxic functions of microglia.
