Oct 24th, 2021 - The transient receptor potential (TRP) superfamily of ion channels is involved in the molecular mechanisms that mediate neuroimmune interactions and activities. Recent advancements in neuroimmunology have identified a role for TRP cation channels in several neuroimmune disorders including amyotropic lateral sclerosis, multiple sclerosis, and myalgic encephalomyelitis/chronic fatigue syndrome (M...

Oct 24th, 2021 - Besides coping with a disease with many uncertainties, people with relapsing-remitting multiple sclerosis face complex decisions concerning disease-modifying therapies (DMTs). In an interview study, we aimed to assess patients' experiences with DMTs. Problem-centred interviews were conducted with 50 people with relapsing-remitting multiple sclerosis in Germany using maximum variation sampling a...

Oct 24th, 2021 - Poly (ADP)-ribose polymerase (PARP) inhibitors have entered routine clinical practice for the treatment of high-grade serous ovarian cancer (HGSOC), yet the molecular mechanisms underlying treatment response to PARP1 inhibition (PARP1i) are not fully understood. Here, we used unbiased mass spectrometry based proteomics with data-driven protein network analysis to systematically characterize how...

Oct 24th, 2021 - Chromosome 22q11.2 deletion syndrome (22q11.2DS) is a multisystem disorder associated with multiple congenital anomalies, variable medical features, and neurodevelopmental differences resulting in diverse psychiatric phenotypes, including marked deficits in facial memory and social cognition. Neuroimaging in individuals with 22q11.2DS has revealed differences relative to matched controls in BOL...

Oct 24th, 2021 - Hepatocellular carcinoma (HCC) is the fifth most common neoplasm in the world. Chronic inflammation of liver and associated wound healing processes collectively contribute to the development of cirrhosis which further progresses to dysplastic nodule and then to HCC. Etiological mediators and ongoing manipulations at cellular level in HCC are well established; however, key protein interactions a...

Oct 24th, 2021 - In patients with glioblastoma, the average survival time with current treatments is short, mainly due to recurrences and resistance to therapy. This insufficient treatment success is, in large parts, due to the tremendous molecular heterogeneity of gliomas, which affects the overall prognosis and response to therapies and plays a vital role in gliomas' grading. In addition, the tumor microenvir...

Oct 24th, 2021 - During the past decade, there have been considerable advances in understanding of the genetic and morphogenic processes underlying cortical malformations and developmental brain tumours. Focal malformations are caused by somatic (postzygotic) variants in genes related to cell growth (ie, in the mTOR pathway in focal cortical dysplasia type 2), which are acquired in neuronal progenitors during n...

Oct 24th, 2021 - Galaxolide and tonalide are well-known polycyclic musks whose intensive use without limitations in numerous cleaning, hygiene, and personal care products has resulted in widespread direct human exposure via absorption, inhalation, and oral ingestion. Latest data shows that long-term, low-dose exposure to toxic chemicals can induce unpredictable harmful effects in a variety of living systems, ho...

Oct 23rd, 2021 - Podocytes are differentiated postmitotic cells which cannot be replaced after podocyte injury. The mechanism of podocyte repopulation after injury has aroused wide concern. Parietal epithelial cells (PECs) are heterogeneous and only a specific subpopulation of PECs has the capacity to replace podocytes. Major progress has been achieved in recent years regarding the role and function of a subset...

Oct 23rd, 2021 - Epigenetic mechanisms which play an essential role in normal developmental processes, such as self-renewal and fate specification of neural stem cells (NSC) are also responsible for some of the changes in the glioblastoma (GBM) genome. Here we develop a strategy to compare the epigenetic and transcriptional make-up of primary GBM cells (GIC) with patient-matched expanded potential stem cell (EP...

Oct 23rd, 2021 - Manipulation of the gut microbiome offers a promising treatment option for children with autism spectrum disorder (ASD) for whom functional gastrointestinal disorders (FGIDs) are a common comorbidity. Both ASD and FGIDs have been linked to dysfunction of the microbiome-gut-brain (MGB) axis. Dysfunction of this bidirectional network has the ability to impact multiple host processes including gas...

Oct 23rd, 2021 - The biological processes associated with postacute sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (PASC) are unknown. We measured soluble markers of inflammation in a SARS-CoV-2 recovery cohort at early (<90 days) and late (>90 days) timepoints. We defined PASC as the presence of 1 or more coronavirus disease 2019 (COVID-19)-attributed symptoms beyond 90 days...

Oct 23rd, 2021 - During pregnancy, the vertical transmission of the Zika virus (ZIKV) can cause some disorders in the fetus, called Congenital Zika Syndrome (CZS). Several efforts have been made to understand the molecular mechanism of the CZS. However, the study of CZS pathogenesis through infected human samples is scarce. Therefore, the main goal of this study is to identify and understand the biological proc...

Oct 22nd, 2021 - Noncirrhotic Portal Hypertension (NCPH) includes a spectrum of chronic liver diseases characterized by increased pressure within the portal circulation in the absence of cirrhosis. The complications from NCPH are similar to that of cirrhosis induced portal hypertension which includes the development of gastrointestinal varices, portal hypertensive gastropathy, splenomegaly, sepsis and ascites. ...

Oct 22nd, 2021 - Smith-Lemli-Opitz Syndrome (SLOS) is an autosomal recessive inborn error of metabolism secondary to cholesterol synthesis abnormalities that usually manifests with a combination of typical dysmorphology and intellectual disability. It is caused by homozygosity for pathological variants of DHCR7, whose protein product catalyzes the conversion of 7-dehydrocholesterol (7-DHC) to cholesterol. This ...

Oct 22nd, 2021 - Auto-immune hemolytic anemia (AIHA) is a heterogeneous syndrome in adults. This disease is associated with significant morbidity-mortality. First-line treatment with prolonged corticosteroid is well identified but there is not enough data about cyclosporine treatment in case of resistance or dependence on steroids. the cyclosporine showed efficacy in many immune cytopenic diseases in the light ...
