Mitoxantrone – an anthraquinone antibiotic with antitumor activity applied for the treatment of multiple sclerosis
Journal Title: Advances in Hygiene and Experimental Medicine - Year 2014, Vol 68, Issue
Abstract
Mitoxantrone is an antineoplastic agent approved for clinical use in the secondary progressive phase of multiple sclerosis (MS). Several scientific reports indicate that mitoxantrone acts through the induction of short-term cell lysis at high concentrations and long-term induction of programmed cell death at lower concentrations of antigen-presenting cells. In this paper, we present the potential cytotoxic effects of mitoxantrone on the cells of the immune system, whose activity is associated with their degenerative effects on axonal myelin sheaths. The article also evaluates the results from the hospital treatment of patients diagnosed with MS. The presented data indicate that, apart from the cytostatic properties, mitoxantrone also exhibits side effects of its clinical application. This drug has high cardiotoxicity, and is associated with decreased left ventricular ejection fraction and increased risk of congestive heart failure. Therefore researchers are currently looking for new substances that can reduce the toxic effects of mitoxantrone in healthy tissues, resulting in the generation of reactive oxygen species during its metabolism.

Tc1-mediated contact sensitivity reaction, its mechanism and regulation
The contact hypersensitivity reaction (CHS) to haptens is a classic example of cell-mediated immune response. In the effector phase, two stages can be distinguished: an early component, that appears only 2 hours after su...
