21. Defensins form a family of microbicidal and cytotoxic peptides made by neutrophils. 22. These pathways are the cytotoxic protein pathway and the Fas ligand pathway. 23. Advances in cytotoxic drugs, pharmacogenetics and targeted drug design show promise. 24. The molecule has been shown to have both cytotoxic and antitumor properties. 25. Other components have cardiotoxic, cytotoxic and neurotoxic effects. 26. Dendritic cells can be stimulated to activate a cytotoxic response towards an antigen. 27. Azathioprine ( Prometheus'Imuran ), is the main immunosuppressive cytotoxic substance. 28. Hematologic neoplasms incidences are most frequent during cytotoxic treatments. 29. Additionally, the leaves, stems, bark, and pollen are cytotoxic . 30. They also mediate chemotaxis, inflammation, and generation of cytotoxic oxygen radicals.
