<scp>LGR</scp> signaling and metabolic regulation: A new frontier in addressing insulin resistance and diabetes treatment

LGR signaling plays a crucial role in metabolic regulation by coordinating muscle-neuron-adipose tissue crosstalk. In response to a high-sugar diet, muscle-derived BMP signaling activates neuronal Bursicon, which stimulates insulin secretion and enhances adipose insulin sensitivity. This evolutionarily conserved pathway underscores LGR4 as a promising therapeutic target for insulin resistance and diabetes.
