Ethnic differences in alpha‐1 antitrypsin deficiency allele frequencies may partially explain national differences in COVID‐19 fatality rates

The FASEB Journal, 2020
Infection rates, severity, and fatalities due to COVID‐19, the pandemic mediated by SARS‐CoV‐2, vary greatly between countries. With few exceptions, these are lower in East and Southeast Asian and Sub‐Saharan African countries compared with other regions.

The Relationship between Plasma Alpha-1-Antitrypsin Polymers and Lung or Liver Function in ZZ Alpha-1-Antitrypsin-Deficient Patients

Biomolecules, 2022
Alpha-1-Antitrypsin (AAT) is a protein of the SERPINA1 gene. A single amino acid mutation (Lys342Glu) results in an expression of misfolded Z-AAT protein, which has a high propensity to intra- and extra-cellular polymerization.

Potent Liver‐Tropic mRNA Lipid Nanoparticles: ApoE‐Mediated Delivery Through a Low‐Density Lipoprotein Receptor Independent Uptake Mechanism

Advanced Materials, EarlyView.
Helper and ionizable lipids play a crucial role in determining ApoE binding and subsequent liver tropism and LDLR‐mediated uptake. Ionizable lipids primarily govern the LDLR‐independent uptake pathway. This complementary interplay between lipid components ultimately governs LNP delivery performance and therapeutic efficacy in the liver.

Systemic modified messenger RNA for replacement therapy in alpha 1-antitrypsin deficiency

Scientific Reports, 2020
Alpha 1-antitrypsin (AAT) deficiency arises from an inherited mutation in the SERPINA1 gene. The disease causes damage in the liver where the majority of the AAT protein is produced.

A Protein‐Centric Strategy Coupled with Match‐Between‐Run Glycoproteomics Enables Discovery of Robust Site‐Specific Glycan Biomarkers for Hepatocellular Carcinoma

Advanced Science, EarlyView.
In this study, a highly robust N‐glycoproteomics (HRN) platform with a newly developed match‐between‐run scheme is used for biomarker discovery. This study proposes a protein‐centric strategy to prioritize proteins susceptible to aberrant glycosylation.

A rare case of alpha 1-antitrypsin deficiency associated with hypogammaglobulinemia and recurrent pulmonary thrombosis

Annals of Thoracic Medicine, 2014
Alpha 1-antitrypsin (AAT) belongs to the family of serpins (serine protease inhibitors). Loop sheet polymerization is the pathology behind serpinopathies which encompasses AAT, anti-thrombin III and neuroserpin deficiency.

Transplant with MZ genotype liver: what is the clinical pulmonary picture after 30 years? a case report and review of the literature

Journal of Medical Case Reports, 2023
Background Alpha-1 antitrypsin, also known as alpha1 proteinase inhibitor, is a protein 90% synthesized by hepatocytes. Alpha-1 antitrypsin deficiency should be suspected if patients have unexplained emphysema or liver disease in the absence of others ...

Structural characterization and conformational dynamics of alpha-1 antitrypsin pathogenic variants causing alpha-1-antitrypsin deficiency

Frontiers in Molecular Biosciences, 2022
Background: Alpha-1 antitrypsin deficiency (A1ATD) is a progressive lung disease caused by inherited pathogenic variants in the SERPINA1 gene. However, their actual role in maintenance of structural and functional characteristics of the corresponding α-1

ERAD Component MoHrd3 Facilitates Pathogenicity and Establishes a Direct Regulation on Autophagy in Magnaporthe Oryzae

Advanced Science, EarlyView.
MoHrd3 plays a crucial role in regulating the pathogenicity of Magnaporthe oryzae. As an ER‐associated degradation component, MoHrd3 involves in ER stress‐triggered autophagy. It facilitates the fusion between the autophagosome and the vacuole via enhancing the interaction between MoAtg8 and MoYpt7.
