Impact of COVID-19 on the thyroid gland : an update

Scappaticcio, Lorenzo ; Pitoia, Fabián ; Esposito, Katherine ; Piccardo, Arnoldo ; Trimboli, Pierpaolo

In: Reviews in Endocrine and Metabolic Disorders, 2020, p. 13

Coronavirus disease 2019 (COVID-19) is the pandemic of the new millennium. COVID-19 can cause both pulmonary and systemic inflammation, potentially determining multi-organ dysfunction. Data on the relationship between COVID-19 and thyroid have been emerging, and rapidly increasing since March 2020. The thyroid gland and the virus infection with its associated inflammatory-immune responses are...

Antimicrobial effects of antipyretics

Zimmermann, Petra ; Curtis, Nigel

In: Antimicrobial Agents and Chemotherapy, 2017, vol. 61, no. 4, p. -

Antipyretics are some of the most commonly used drugs. Since they are often coadministered with antimicrobial therapy, it is important to understand the interactions between these two classes of drugs. Our review is the first to summarize the antimicrobial effects of antipyretic drugs and the underlying mechanisms involved. Antipyretics can inhibit virus replication, inhibit or promote...

Cathepsin B increases ENaC activity leading to hypertension early in nephrotic syndrome

Larionov, Alexey ; Dahlke, Eileen ; Kunke, Madlen ; Rodriguez, Luis Zanon ; Schiessl, Ina M. ; Magnin, Jean‐Luc ; Kern, Ursula ; Alli, Abdel A. ; Mollet, Geraldine ; Schilling, Oliver ; Castrop, Hayo ; Theilig, Franziska

In: Journal of Cellular and Molecular Medicine, 2019, vol. 23, no. 10, p. 6543–6553

The NPHS2 gene, encoding the slit diaphragm protein podocin, accounts for genetic and sporadic forms of nephrotic syndrome (NS). Patients with NS often present symptoms of volume retention, such as oedema formation or hypertension. The primary dysregulation in sodium handling involves an inappropriate activation of the epithelial sodium channel, ENaC. Plasma proteases in a...

The human transmembrane protease serine 2 is necessary for the production of group 2 influenza A virus pseudotypes

Ferrara, Francesca ; Molesti, Eleonora ; Böttcher-Friebertshäuser, Eva ; Cattoli, Giovanni ; Corti, Davide ; Scott, Simon D. ; Temperton, Nigel J.

In: Journal of molecular and genetic medicine, 2013, vol. 7, p. 309-314

The monomer of influenza haemagglutinin is synthesized as a single polypeptide precursor that during maturation is cleaved by proteases into two active subunits. Other studies have demonstrated that the human Transmembrane Protease Serine 2 (TMPRSS2) can cleave the HA of human seasonal influenza viruses. Consequently, we have investigated the use of human Transmembrane Protease Serine 2 to...

Factors that influence the immune response to vaccination

Zimmermann, Petra ; Curtis, Nigel

In: Clinical Microbiology Reviews, 2019, vol. 32, no. 2, p. e00084-18

There is substantial variation between individuals in the immune response to vaccination. In this review, we provide an overview of the plethora of studies that have investigated factors that influence humoral and cellular vaccine responses in humans. These include intrinsic host factors (such as age, sex, genetics, and comorbidities), perinatal factors (such as gestational age, birth weight,...

Physiological and Molecular Responses to Altered Sodium Intake in Rat Pregnancy

Eisele, Nicole ; Klossner, Rahel ; Escher, Geneviève ; Rudloff, Stefan ; Larionov, Alexey ; Theilig, Franziska ; Mohaupt, Markus G. ; Mistry, Hiten D. ; Gennari‐Moser, Carine

In: Journal of the American Heart Association, 2018, p. -

In pregnancy, a high plasma volume maintains uteroplacental perfusion and prevents placental ischemia, a condition linked to elevated maternal blood pressure (BP). Reducing BP by increasing Na+ intake via plasma volume expansion appears contra‐ intuitive. We hypothesize that an appropriate Na+ intake in pregnancy reduces maternal BP and adapts the renin‐angiotensin system in a...
