**Background of LRP5 Antibodies**
LRP5 (low-density lipoprotein receptor-related protein 5) is a transmembrane receptor critical in the Wnt/β-catenin signaling pathway, regulating processes like bone development, metabolism, and cell proliferation. Mutations in *LRP5* are linked to skeletal disorders (e.g., osteoporosis-pseudoglioma syndrome) and diseases such as cancer, diabetes, and retinal angiogenesis. LRP5 antibodies are tools or therapeutic agents designed to modulate this pathway.
In research, anti-LRP5 antibodies help dissect Wnt signaling mechanisms, either by blocking ligand-receptor interactions (antagonists) or stabilizing them (agonists). Therapeutically, they are explored for treating bone disorders, cancers (e.g., colorectal, breast), and metabolic diseases. For instance, inhibiting LRP5 may suppress tumor growth by disrupting Wnt-driven proliferation. Conversely, activating LRP5 could enhance bone formation in osteoporosis.
Monoclonal antibodies targeting LRP5 are in preclinical development, with challenges including specificity and avoiding off-target effects in related receptors (e.g., LRP6). Their clinical potential hinges on balancing pathway modulation with safety. Overall, LRP5 antibodies represent a promising yet complex avenue for precision medicine in diverse diseases.
