Functions of SETD7 during development, homeostasis and cancer

2019

A controlled organ homeostasis is essential to sustain the integrity of any living organism. This homeostasis relies on stem cells, which maintain themselves and give rise to the various types of differentiated cells. It is well established that the differentiation of pluripotent embryonic stem cells (ESCs) depends on major changes in transcriptional programs. Covalent modifications of DNA, RNA and proteins are instrumental in setting up the genetic programs associated with cell fates. Another important mechanism for regulation of gene expression is protein localisation and stability. In addition to ubiquitination, SUMOylation and phosphorylation, methylation of proteins is an important det…

Time to activin on pathogenic T cells

2020

In multiple sclerosis (MS), Th17 cells are critical drivers of autoimmune central nervous system (CNS) inflammation and demyelination. Th17 cells exhibit functional heterogeneity fostering both pathogenic and nonpathogenic, tissue-protective functions. Still, the factors that control Th17 pathogenicity remain incompletely defined. Here, using experimental autoimmune encephalomyelitis, an established mouse MS model, we report that therapeutic administration of activin-A ameliorates disease severity and alleviates CNS immunopathology and demyelination, associated with decreased activation of Th17 cells. In fact, activin-A signaling through activin-like kinase-4 receptor represses pathogenic t…

The integration of autophagy and cellular trafficking pathways via RAB GAPs.

2015

Macroautophagy is a conserved degradative pathway in which a double-membrane compartment sequesters cytoplasmic cargo and delivers the contents to lysosomes for degradation. Efficient formation and maturation of autophagic vesicles, so-called phagophores that are precursors to autophagosomes, and their subsequent trafficking to lysosomes relies on the activity of small RAB GTPases, which are essential factors of cellular vesicle transport systems. The activity of RAB GTPases is coordinated by upstream factors, which include guanine nucleotide exchange factors (RAB GEFs) and RAB GTPase activating proteins (RAB GAPs). A role in macroautophagy regulation for different TRE2-BUB2-CDC16 (TBC) dom…

Guidelines Have a Key Role in Driving HCV Elimination by Advocating for Simple HCV Care Pathways.

2021

The availability of pangenotypic direct-acting antivirals for treatment of hepatitis C (HCV) has provided an opportunity to simplify patient pathways. Recent clinical practice guidelines have recognised the need for simplification to ensure that elimination of HCV as a public health concern remains a priority. Despite the move towards simplified treatment algorithms, there remains some complexity in the recommendations for the management of genotype 3 patients with compensated cirrhosis. In an era where additional clinical trial data are not anticipated, clinical guidance should consider experience gained in real-world settings. Although more experience is required for some pangenotypic the…

Managing stress during the coronavirus disease 2019 pandemic and beyond: Reappraisal and mindset approaches

2020

The novel coronavirus disease 2019 (COVID‐19) pandemic is a global public health crisis of a scale not previously experienced in modern times (Kickbusch et al., 2020). Governmental ‘lockdown’ measures aimed at minimizing virus transmission including ‘stay at home’ orders, closure of businesses and places of congregation, and travel restrictions have had a substantive societal impact that permeates almost every facet of daily life (Gostin & Wiley, 2020; Shanafelt, Ripp, & Trockel, 2020). These widespread changes represent considerable sources of stress in the population and will have deleterious effects on mental and physical health going forward. As nations begin to emerge from ‘lockdown’, …

Kawasaki disease epidemic: pitfalls

2020

AbstractRecent reports have described in the pediatric population a new type of hyperinflammatory response manifested following contact with SARS-CoV-2, with some of the clinical features attributable to Kawasaki disease (KD). The purpose of this commentary is to remark on a possible recent association between SARS-CoV-2 and KD. Although today little is known about the etiology of KD, the most accepted hypothesis is that of a probable viral etiology, therefore, even the SARS-CoV-2 virus could trigger, in genetically predisposed subjects, an exaggerated inflammatory response that is clinically evident like the one described in KD.

Acute cholecystitis during COVID-19 pandemic: a multisocietary position statement

2020

AbstractFollowing the spread of the infection from the new SARS-CoV2 coronavirus in March 2020, several surgical societies have released their recommendations to manage the implications of the COVID-19 pandemic for the daily clinical practice. The recommendations on emergency surgery have fueled a debate among surgeons on an international level.We maintain that laparoscopic cholecystectomy remains the treatment of choice for acute cholecystitis, even in the COVID-19 era. Moreover, since laparoscopic cholecystectomy is not more likely to spread the COVID-19 infection than open cholecystectomy, it must be organized in such a way as to be carried out safely even in the present situation, to gu…
