Abstract
Triggering receptor expressed on myeloid cells 2 (TREM2) is a membrane glycoprotein that plays a crucial role in the regulation of microglial survival, activation, phagocytosis, as well as in the maintenance of brain homeostasis and the inflammatory response to injury or neurodegeneration. This review provides a comprehensive overview of TREM2 structure and functions, highlighting the role of its variants in the development and progression of Alzheimer's disease (AD), a devastating neurodegenerative disease that affects millions of people worldwide. Additionally, the article discusses the potential of TREM2 as a therapeutic target in AD, analyzing the current state of research and future prospects. Given the significant challenges associated with the activation of TREM2, particularly due to its diverse isoforms and the delicate balance required to modulate the immune response without triggering hyperactivation, this review aims to enhance our understanding of TREM2 in AD and inspire further research into this promising yet challenging therapeutic target.
期刊介绍:
Molecular and Cellular Neuroscience publishes original research of high significance covering all aspects of neurosciences indicated by the broadest interpretation of the journal''s title. In particular, the journal focuses on synaptic maintenance, de- and re-organization, neuron-glia communication, and de-/regenerative neurobiology. In addition, studies using animal models of disease with translational prospects and experimental approaches with backward validation of disease signatures from human patients are welcome.
