This study comprehensively discusses the molecular structure, enzymatic functions, and signaling pathways associated with LACC1. Notably, the M-CSF/AKT/mTOR/LACC1 pathway primarily regulates cellular autophagy. Additionally, the PPARα/RXR/PPRE/LACC1, miR-211-5p/KDM2B/LACC1, LACC1/AMPK/NLRP3, LACC1/NF-kB, LACC1/MAPK, LACC1/ROS/NOD2/PIPK2, LACC1/JAK-STAT, and LACC1/CCL5 signaling pathways are significantly involved in modulating inflammatory responses. Furthermore, the article provides a comprehensive summary of the pathogenic mechanisms and recent advancements in research concerning LACC1 in immune diseases, metabolic disorders, infectious diseases, and neurological conditions. In conclusion, LACC1 serves as a pivotal immune-metabolic hub, offering new insights and potential therapeutic targets for the study of related diseases.
