Melittin: A promising therapeutic agent for rheumatoid arthritis treatment.

Rheumatoid Arthritis (RA) is a globally prevalent chronic disease that presents significant challenges in terms of curability. The etiology and onset of RA are not readily identifiable, and as the disease advances, it is characterized by joint pain, swelling, and damage, potentially resulting in paralysis. The adverse effects associated with existing pharmacological treatments are considerable, and prolonged use may pose significant health risks. Melittin, a naturally occurring anti-rheumatic compound, has garnered increasing scholarly interest. Melittin has demonstrated the potential to significantly augment the therapeutic efficacy of certain first-line pharmacological agents while minimizing adverse effects, thereby rendering it appropriate for prolonged use. Melittin's mechanisms of action in treating RA encompass anti-inflammatory effects, immunomodulatory effects, analgesic effects, reduction of cardiovascular disease risk, and organ-protective effects, targeting multiple aspects of RA to alleviate symptoms. Clarifying the biological functions of melittin and its mechanisms in treating RA can provide valuable insights for the application of melittin in the intervention of RA disease progression. However, melittin can cause allergic reactions, hemolysis, and cytotoxicity in the body, which limit its application. Research has shown that strategies including melittin-based nanomodification, immunoconjugation, and structural regulation can improve the specificity of melittin, decrease cytotoxicity, and mitigate the lytic effects on non-target cells of bee venom. These findings suggest that melittin holds promise for clinical applications. This article provides a comprehensive overview of the disease progression associated with RA, examines the biological properties of Mmelittin, and discusses therapeutic strategies for utilizing melittin in the treatment of rheumatoid arthritis. The objective is to mitigate the toxic side effects of melittin while enhancing its targeted anti-inflammatory effects, thereby investigating its potential clinical value in the prevention of rheumatoid arthritis.
