Royal jelly (RJ)

Royal jelly is a complex biological secretion produced by the hypopharyngeal and mandibular glands of worker honey bees (Apis mellifera), serving as the primary nutritional source for larvae and the exclusive diet of the queen bee (PMID: 30130494). It is a heterogeneous mixture composed of water, proteins (notably Major Royal Jelly Proteins or MRJPs), lipids (specifically 10-hydroxy-2-decenoic acid), carbohydrates, and vitamins (PMID: 28814854). While it is widely studied for its pharmacological potential, royal jelly is a natural product mixture rather than a specific molecular therapeutic target like a receptor or enzyme. Its bioactive components are reported to modulate various physiological pathways, including estrogen receptor signaling and antioxidant defense mechanisms, contributing to its anti-inflammatory and anti-aging properties (PMID: 31591341). Clinical interest in royal jelly focuses on its potential for managing menopausal symptoms, metabolic syndrome, and wound healing, although it is not a drug target itself. A significant therapeutic challenge is its high allergenicity, as it can induce severe hypersensitivity reactions and anaphylaxis in susceptible individuals (PMID: 25561231).

Royal jelly functions as a multi-component bioactive substance rather than a target; its lipid component 10-HDA acts as a fatty acid that can modulate estrogen receptors, while MRJPs exhibit growth factor-like effects on various cell types (PMID: 22110774).
