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.

Malectin Alleviates Endoplasmic Reticulum Stress in Gestational Diabetes Mellitus via Glycoprotein Quality Control Mechanisms

Advanced Science, EarlyView.
Malectin alleviates high glucose‐induced ER stress and damage in placental trophoblasts, a function dependent on its six critical carbohydrate‐binding residues. In a GDM mouse model, administration of TAT‐Malectin ameliorated hyperglycemia and placental ER stress and prevented fetal macrosomia.

Alpha 1-Antitrypsin Deficiency: A Disorder of Proteostasis-Mediated Protein Folding and Trafficking Pathways

International Journal of Molecular Sciences, 2020
Human cells express large amounts of different proteins continuously that must fold into well-defined structures that need to remain correctly folded and assemble in order to ensure their cellular and biological functions.

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.

Tumor‐Derived Alpha‐1 Antitrypsin Promotes Liver Metastasis of Colorectal Cancer Through the Neutrophil Extracellular Traps–CCDC25 Pathway

Advanced Science, EarlyView.
ABSTRACT Liver metastasis is a leading cause of mortality in colorectal cancer (CRC), where the inflammatory tumor microenvironment, specifically neutrophil infiltration, significantly promotes metastatic colonization. This study reveals a pro‐metastatic role for alpha‐1 antitrypsin (A1AT) in CRC liver metastasis via a dual mechanism involving ...

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

Pregnancy and alpha-1 antitrypsin deficiency [PDF]

Postgraduate Medical Journal, 1987
Summary A 29 year old patient with alpha-1 antitrypsin deficiency and bullous emphysema became pregnant against the advice of her physicians. Despite a mid-trimester pneumothorax requiring the insertion of a chest tube, she went on to deliver a healthy child under epidural anaesthesia using a midforceps technique. Vaginal delivery is not

Therapy for Myhre Syndrome: Goals, Misconceptions, and Current Agents

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre Syndrome (MYHRS, MIM #139210) is a rare, multisystem connective tissue disorder caused by recurrent heterozygous gain‐of‐function pathogenic variants in the SMAD4 gene, a key player in TGF‐β signaling and a regulator of extracellular matrix homeostasis.

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 ...
