Myelotoxicity is a medical condition that causes the decrease of the production of cells responsible for immunity (leukocytes), carrying oxygen (erythrocytes), and/or for normal blood clotting (thrombocytes) due to bone marrow suppression.
Myeloperoxidase (MPO) is a peroxidase enzyme found most abundantly in white blood cells neutrophil granulocytes.
Myeloperoxidase (MPO) processes a critical role that protects our body against the invasion of microorganisms.
In cellular levels, myeloperoxidase (MPO) plays a critical role as a local mediator of tissue damage by stimulating the production of proinflammatory cytokines to protect the cell against foreign pathogens in the induction of acute phase of infection.
In other words, MPO deficiency induces the exaggerates of the inflammatory response that affects neutrophil functions including cytokine production in the acute phase of infection that can lead to chronic low-grade inflammatory disease.
MPO deficiency has been found in patients with diabetes mellitus, pregnancy, iron deficiency, renal transplantation, thrombotic diseases, lead poisoning, obstructive jaundice, disseminated cancers, hematologic disorders, and neoplasms.
However, genetic preposition may be the primary condition that causes the onset of PMO deficiency.
Dr. Roma Pahwa wrote, "Primary MPO deficiency is inherited as an autosomal recessive disorder and is generally present with varying degree of severity and clinical features. A number of point germline mutations resulting in MPO deficiency have been detected in the primary form".
And, " Some of these mutations are associated with the defective posttranslational processing of the MPO precursor protein and others with pre-translational defects caused by mutations in the regulatory portion of the MPO gene".
On finding a potential compound for the treatment of neutropenia, researchers examined the effects of Tussilago farfara L. polysaccharides on the immune response of lung cancer animal model.
The study included selected C57Bl/6 mice with Lewis lung carcinoma treated by conventional cisplatin/paclitaxel polychemotherapy before administrating additional Tussilago farfara L. polysaccharides.
According to the tested analysis, Tussilago farfara L. polysaccharides not only reduced the side effects of cisplatin/paclitaxel polychemotherapy induced myelotoxicity associated with moderated neutropenia but also enhanced the efficacy of the chemo drugs activity.
