NTSR2 (neurotensin receptor 2) is a G protein-coupled receptor that mediates diverse physiological functions through neurotensin signaling. The receptor plays a critical role in metabolic regulation, particularly in adipose tissue where NTS-NTSR2 signaling suppresses food intake by regulating ceramide metabolism and GDF15 production in white adipocytes 1. NTSR2 also functions as an anti-thermogenic mediator, reducing brown adipose tissue thermogenesis through ERK signaling pathways 2. In the nervous system, NTSR2 is primarily expressed in the brain and contributes to stress-related disorders, with involvement in post-traumatic stress disorder and fear memory processing 3. The receptor shows therapeutic potential in pain management, though SBI-810's analgesic effects specifically require NTSR1 rather than NTSR2 4. In hematological malignancies, NTSR2 expression is dysregulated, being overexpressed in B cell leukemia compared to healthy B lymphocytes 5. The receptor has been successfully targeted using CRISPR-Cas9 editing in primary human dorsal root ganglion neurons, demonstrating its accessibility for genetic manipulation 6. These findings establish NTSR2 as a promising therapeutic target across multiple disease contexts.
