- 1. M protein
- [A protein complex comprised of two heavy chains and two light chains. Monoclonal immunoglobulin (M protein) is found in abundance in patients who have multiple myeloma. The protein is not produced in response to an antigen, but it is expressed in malignant plasma cells and excreted into the blood and urine. ( NCI )] (UMLS (CSP) C0700271) =Amino Acid, Peptide, or Protein; Immunologic Factor
| - 2. MPP+
- [An active neurotoxic metabolite of 1-METHYL-4-PHENYL-1,2,3,6-TETRAHYDROPYRIDINE. The compound reduces dopamine levels, inhibits the biosynthesis of catecholamines, depletes cardiac norepinephrine and inactivates tyrosine hydroxylase. These and other toxic effects lead to cessation of oxidative phosphorylation, ATP depletion, and cell death. The compound, which is related to PARAQUAT, has also been used as an herbicide.
