Function of monocytes and monocyte-derived macrophages in α1-antitrypsin deficiency.

α1-antitrypsin deficiency is the most widely recognised genetic disorder causing chronic obstructive pulmonary disease (COPD). Mutant Z α1-antitrypsin expression has previously been linked to intracellular accumulation and polymerisation of this proteinase inhibitor. Subsequently, this has been described to underlie an exaggerated endoplasmic reticulum stress response and enhanced nuclear facto...

α1-Antitrypsin deficiency: count me in please!

Respiratory medicine is facing formidable challenges in the 21st century. Indeed, most respiratory medical research is becoming interconnected, translational and transnational, all embedded within so-called “planetary health” [1]. However, renewing estimates and trends from classical, descriptive epidemiology, including how many patients of a given condition are around, and how many are expecte...

Oxidative metabolism in cord blood monocytes and monocyte-derived macrophages.

Little is known about phagocytosis-associated oxidative metabolism in mononuclear phagocytes from the human neonate. We investigated this phenomenon in monocytes from the cord blood of term newborn infants by measuring generation of superoxide anion (O2-) and hydroxyl radical (X OH) after stimulation with opsonized zymosan or phorbol myristate acetate. Production of these microbicidal oxygen me...

Circulating polymers in α1-antitrypsin deficiency.

Most individuals carry two wild-type M alleles of the SERPINA1 gene which encodes a1-antitrypsin. 95% of severe deficiency of a1-antitrypsin is associated with the Z allele (Glu342Lys; denoted PiZZ in the homozygote), and with the retention and polymerisation of a1-antitrypsin within hepatocytes [1]. These polymers are contained within periodic acid–Schiff-positive, diastase-resistant inclusion...

Molecular Mechanism of Z α1-Antitrypsin Deficiency*

The Z mutation (E342K) of α1-antitrypsin (α1-AT), carried by 4% of Northern Europeans, predisposes to early onset of emphysema due to decreased functional α1-AT in the lung and to liver cirrhosis due to accumulation of polymers in hepatocytes. However, it remains unclear why the Z mutation causes intracellular polymerization of nascent Z α1-AT and why 15% of the expressed Z α1-AT is secreted in...
