PLOD1 and thyroiditis: The FSH receptor belongs to a subgroup of G-protein-coupled, seven-transmembrane receptors,34 consisting of receptors for the luteinizing hormone (LH)35 and thyroid stimulating hormone (TSH).36 Based on the present approach, the conjugation of a NIR-II fluorophore to the paralogous LH or TSH in the future could allow imaging of specific target cells expressing LH receptors (theca, luteal, and mature granulosa cells in the ovary and Leydig cells in the testes) and TSH receptors (thyroid nodules).
