New insights in primary ciliary dyskinesia
2017
Introduction: Primary ciliary dyskinesia (PCD) is a rare genetic disease with an estimated prevalence of 1:20.000 births. It is characterized by abnormal motility of cilia, leading to impaired mucociliary clearance, and subsequent infection and chronic inflammation of the airways. PCD also affects spermatozoa and cilia in the Fallopian tubes, contributing to fertility issues; dyskinesia of embryonic nodal cilia causes a random distribution of the organs. Areas covered: An overview of the history, genetics, clinical manifestations in children and adults, diagnostic tests, treatments, and prognosis are reviewed. We also discuss current research and future prospects of PCD. Expert opinion: As …
Potential Influence of Helminth Molecules on COVID-19 Pathology
2020
In recent months, the parasitology research community has been tasked with investigation of the influence of parasite coinfection on coronavirus disease 2019 (COVID-19) outcomes. Herein, we share our approach to analyze the effect of the trematode Fasciola hepatica as a modulator of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and of COVID-19 pathology.
Cystic fibrosis treatment: targeting the basic defect
2017
ABSTRACTIntroduction: Cystic Fibrosis (CF) is a disease caused by different class mutations in the CF transmembrane conductance regulator (CFTR) gene. It can therefore benefit from a personalized medicine approach based on the individual genotype of each patient.Areas covered: This review provides a detailed overview of the current major development of new CF treatments that target the basic CF defect. The review summarizes gene therapy, mRNA repair strategies, read-through agents, and CFTR-modulators (potentiators, correctors, stabilizers, amplifiers and different combination therapies).Expert opinion: We are currently perhaps at the most exciting stage in the history of CF, with the poten…
TTF-1/p63-Positive Poorly Differentiated NSCLC: A Histogenetic Hypothesis from the Basal Reserve Cell of the Terminal Respiratory Unit
2020
TTF-1 is expressed in the alveolar epithelium and in the basal cells of distal terminal bronchioles. It is considered the most sensitive and specific marker to define the adenocarcinoma arising from the terminal respiratory unit (TRU). TTF-1, CK7, CK5/6, p63 and p40 are useful for typifying the majority of non-small-cell lung cancers, with TTF and CK7 being typically expressed in adenocarcinomas and the latter three being expressed in squamous cell carcinoma. As tumors with coexpression of both TTF-1 and p63 in the same cells are rare, we describe different cases that coexpress them, suggesting a histogenetic hypothesis of their origin. We report 10 cases of poorly differentiated non-small-…
Oxidative Stress and Endoplasmic Reticulum Stress in Rare Respiratory Diseases
2021
Several studies have shown that some rare respiratory diseases, such as alpha-1 antitrypsin deficiency (AATD), idiopathic pulmonary fibrosis (IPF), cystic fibrosis (CF), and primary ciliary dyskinesia (PCD) present oxidative stress (OS) and endoplasmic reticulum (ER) stress. Their involvement in these pathologies and the use of antioxidants as therapeutic agents to minimize the effects of OS are discussed in this review.
Autoimmune polyglandular diseases.
2019
Autoimmune polyglandular diseases (APD) are defined as the presence of two autoimmune -induced endocrine failures. With respect to the significant morbidity and potential mortality of APD, the diagnostic objective is to detect APD at an early stage, with the advantage of less frequent complications, effective therapy and better prognosis. This requires that patients at risk be regularly screened for subclinical endocrinopathies prior to clinical manifestation. Regarding the time interval between manifestation of first and further endocrinopathies, regular and long-term follow-up is warranted. Quality of life and psychosocial status are poor in APD patients and involved relatives. Familial c…
Les bronchospasmes iatrogènes
2016
Resume Les bronchospasmes sont des effets indesirables pouvant mettre en jeu le pronostic vital. Les symptomes ressemblent a ceux de la crise d’asthme aigue grave. Le pharmacien doit savoir reconnaitre ces signes, mais aussi envisager la cause iatrogene afin d’identifier le plus vite possible le traitement suspect et conseiller au mieux le patient sur la conduite a tenir.
Transcriptomic study of the toxic mechanism triggered by beauvericin in Jurkat cells
2018
Beauvericin (BEA), an ionophoric cyclic hexadepsipeptide mycotoxin, is able to increase oxidative stress by altering membrane ion permeability and uncoupling oxidative phosphorylation. A toxicogenomic study was performed to investigate gene expression changes triggered by BEA exposure (1.5, 3 and 5 mu M; 24 h) in Jurkat cells through RNA-sequencing and differential gene expression analysis. Perturbed gene expression was observed in a concentration dependent manner, with 43 differentially expressed genes (DEGs) overlapped in the three studied concentrations. Gene ontology (GO) analysis showed several biological processes related to electron transport chain, oxidative phosphorylation, and cel…
Plasmin-Induced Activation of Human Platelets Is Modulated by Thrombospondin-1, Bona Fide Misfolded Proteins and Thiol Isomerases
2020
Inflammatory processes are triggered by the fibrinolytic enzyme plasmin. Tissue-type plasminogen activator, which cleaves plasminogen to plasmin, can be activated by the cross-&beta
