Therapeutic intervention in inflammatory pathologies and cancer : understanding the anti-inflammatory properties of Viscum album

Abstract : Recent advances in immunology research have led us towards more promising approaches and strategies to manipulate the immune response to prevent or treat the diseases related to immune dysfunction such as autoimmune, inflammatory pathologies and malignant diseases. Although, immuno inflammation is a basal physiological phenomenon required to eliminate the causative agent and to initiate the healing process, it is a physiopathological symptom in a diverse conditions of infectious, autoimmune and tumoral origin. Various therapeutic strategies have been developed in order to reduce inflammation and pain, including the treatment with cytokine neutralizing antibodies, molecular antagonists, intravenous immunoglobulins, corticosteroids, non-steroid anti-inflammatory drugs (NSAID) and several others. In addition to these well known anti-inflammatory therapeutic strategies, treatment with various phytotherapeutics has also contributed enormously to control inflammation and pain, associated with various severe inflammatory disorders and cancer. Viscum album (VA) preparations, commonly known as European mistletoe, are extensively used as complementary therapy in cancer for decades. However the mechanisms of action have been partially understood. Several mutually non-exclusive mechanisms have been proposed such as anti-tumor properties which involve the cytotoxic properties, induction of apoptosis, inhibition of angiogenesis and several other immunomodulatory mechanisms. This study reveals anti-inflammatory mechanism as another important mechanism of action of these phytotherapeutics, which is responsible for their therapeutic benefit and addresses the molecular mechanisms in the pro-inflammatory axis of COX-2 and PGE2 using in vitro experimental model of human lung adenocarcinoma. The present work contributes for a better understanding of mechanisms of action of Viscum album preparations underlying their therapeutic benefit and allows us to revitalize the therapeutic strategies used in treatment of inflammatory disorders and cancer.
