[Myeloperoxidase of neutrophils and its possible role in lipid peroxidation processes in arteriosclerosis]
Abstract:
Activity of blood plasma myeloperoxidase (MPO) of neutrophil leucocytes and acetyl hydroperoxides was studied in families of atherosclerosis patients. The neutrophil MPO activity was decreased and the blood plasma content of acetyl hydroperoxides was increased in subjects with hereditary predisposition to atherosclerosis. The role of MPO and its possible pathogenetic action as a generator of the active forms of oxygen in atherosclerosis and its complications has been discussed.
Insights
Atherosclerosis patients with a hereditary predisposition showed decreased neutrophil myeloperoxidase (MPO) activity and increased acetyl hydroperoxides. This suggests MPO
Area of Science:
- Biochemistry
- Cardiovascular Research
- Genetics
Context:
- Investigates biomarkers in families of atherosclerosis patients.
- Focuses on neutrophil myeloperoxidase (MPO) and acetyl hydroperoxides.
- Examines hereditary predisposition to atherosclerosis.
Purpose:
- To study the activity of blood plasma myeloperoxidase (MPO) and acetyl hydroperoxides in families of atherosclerosis patients.
- To identify potential biomarkers associated with hereditary atherosclerosis.
- To explore the role of MPO in the pathogenesis of atherosclerosis.
Summary:
- Neutrophil MPO activity was found to be decreased in individuals with a hereditary predisposition to atherosclerosis.
- Blood plasma acetyl hydroperoxide levels were elevated in subjects with a hereditary predisposition to atherosclerosis.
- The study discusses the potential role of MPO as an active oxygen species generator in atherosclerosis.
Impact:
- Provides insights into the biochemical mechanisms underlying hereditary atherosclerosis.

Protein Modifications in the RER
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal sequences.
Peroxisomes
Protein Import into the Peroxisomes
Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...

Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...
