LRRTM2 and hydrops fetalis: Key findings include: a) SGLT2 inhibitors downregulate pro-inflammatory genes in adipose tissue, reducing immune cell infiltration and ferroptosis; b) Genetic evidence highlights CXCL10 as a mediator of anti-inflammatory effects, with its inhibition linked to reduced HF risk; c) LRRTM2, a protein associated with synaptic formation, emerged as a critical mediator, with genetic links to reduced HF risk via SGLT2 inhibition.
