Ligand Availability Protocols

Meaning

Ligand Availability Protocols are clinical strategies specifically designed to optimize the concentration and presentation of signaling molecules (ligands), such as hormones or growth factors, to their respective target receptors. This involves not only managing the total circulating level of a hormone but also ensuring its unbound, biologically active fraction is maximized. The protocols aim to overcome limitations imposed by binding proteins, such as Sex Hormone-Binding Globulin (SHBG), or inefficient transport mechanisms. Maximizing free hormone availability is crucial for effective cellular signaling.
