Lactate dehydrogenase A (LDHA) is upregulated in spinal cord injury (SCI), driving immune responses and metabolic changes. Inhibiting LDHA may offer a therapeutic strategy for SCI.
Area of Science:
- Neuroscience
- Metabolic Regulation
- Immunology
Background:
- Lactate metabolism and lactylation are implicated in neurological disorders.
- The role of lactylation in spinal cord injury (SCI) is not well understood.
- Lactate dehydrogenase A (LDHA) is a key enzyme in lactate metabolism.
Purpose of the Study:
- To investigate the role of lactylation-related genes in SCI.
- To identify potential diagnostic biomarkers and therapeutic targets for SCI.
Main Methods:
- Bioinformatic analysis of SCI transcriptomes (GEO database).
- Identification of differentially expressed lactylation-related genes (DE-LRGs).
- Validation in rat SCI models using immunofluorescence and Western blot.
Main Results:
- LDHA was significantly upregulated in SCI and linked to T cell infiltration.
- LDHA promoted immune activation, metabolic reprogramming, and stress responses in SCI.
- LDHA inhibition attenuated SCI-induced inflammation and immune cell infiltration.
Conclusions:
- LDHA is a key regulator in SCI pathogenesis, involving metabolic reprogramming and immune modulation.
- LDHA shows promise as a diagnostic biomarker and therapeutic target for SCI.
