Central insulin resistance has been determined to play an important role in the progress of AD. However, the mechanism underlying the development of disrupted insulin signalling pathways in AD is unclear. Suppressor of cytokine signalling 3 (SOCS3) is a member of the SOCS protein family that acts as a negative modulator of insulin signalling in sensitive tissues, such as hepatocytes and adipocytes. However, little is known about its role in neurological diseases. Recent evidence indicates that the level of SOCS3 is increased in the brains of individuals with AD, especially in areas with amyloid beta (Aβ) deposition, suggesting that SOCS3 may regulate the central insulin signalling pathways in AD. Here, we discuss the potential role of SOCS3 in AD and speculate that SOCS3 may be a promising therapeutic target for the treatment of AD.
