Cellular aspects of the immunomodulating activity of a proprietary mistletoe extract (Eurixor) standardized for mistletoe lectin-1 (ML-1) were investigated in patients suffering from mammary carcinoma (n = 20). Regular subcutaneous injections of the different dosages (0.5 and 1.0 ng ML-1/kg body weight, twice a week, for 5 weeks) yielded statistically significant increases of defined peripheral blood lymphocyte subsets (helper T-cells, natural killer (NK)-cells) which are generally believed to be involved in antitumor activity. Moreover, administration of either ML-1 concentration resulted in enhanced expression of activation markers such as interleukin-2 receptors and HLA/DR-antigens on peripheral blood T-lymphocytes. This study suggests that regular subcutaneous administration of both ML-1 concentrations (0.5 and 1.0 ng/kg body weight) can efficiently stimulate the cellular immune system of cancer patients.

Viscum album lectin 1 (Viscumin) is one of the most important plant-based protein of potential adjuvant in cancer treatment. Therefore, the use of nano-biosensor technology as a novel emerges of biosensors is crucial to detect this modal agent in pharmacological study. Molecular imprinted polymer using 9-mer peptides sequence (epitope) was applied as a template.

Mistletoe lectin-1 (ML1) is a nature-derived macromolecular cytotoxin that potently induces apoptosis in target cells. Non-specific cytotoxicity to normal cells is one of the major risks in its clinical application, and we therefore propose to encapsulate ML1 in a nanocarrier that can specifically release its cargo intratumorally, thus improving the efficacy to toxicity ratio of the cytotoxin. We investigated the encapsulation of ML1 in ultrasound-sensitive liposomes (USL) and studied its release by high-intensity focused ultrasound (HAccessedIFU).

Background: Extracts from (VE) are used in the complementary cancer therapy in Europe for decades. VE contain several compounds like the mistletoe lectins (MLs) 1-3 and viscotoxins and also several minor ingredients. Since mistletoe lectin 1 (ML-1) has been described as the main component of VE harboring antitumor activity, purified native or recombinant ML-1 has been recently used in clinical trials.

Ethnopharmacological Relevance: Mistletoe has been used since ancient times in Europe mostly for medicinal purposes. Since 1917, mistletoe preparations have been applied in cancer therapy and today are the most frequently used complementary medicine in tumor treatment. The main cytotoxic constituents of Viscum album are lectins and viscotoxins.
