LINGO1 (Leucine Rich Repeat and Ig Domain Containing 1): LINGO1 is a protein that plays a critical role in neural development, especially in the myelination of neurons. It functions as a negative regulator of oligodendrocyte differentiation and myelination. LINGO1 has been linked to neurodegenerative diseases such as multiple sclerosis and Parkinson’s disease. Inhibiting LINGO1 is being studied as a potential therapeutic strategy to promote remyelination and support neural repair in these conditions.
