A targeted treatment for IgA nephropathy at last?

Eurekalert - Jun 07 2021 - 00:06
Due to the immunological pathogenesis of IgA nephropathy, patients used to be given immunosuppressive therapy; however, this was shown to have no long-term benefit over optimal supportive therapy. Promising data from the interim analysis of a Phase II study with iptacopan now show that the targeted inhibition of a specific factor of the immune system allows a specific approach to therapy for IgAN without burdening patients with the severe side effects of immunosuppression.

A mechanism through which 'good' viruses kill 'bad' bacteria and block their reproduction

Eurekalert - Jun 07 2021 - 00:06
Researchers at Tel Aviv University discovered a process by which a "good" virus selectively destroys the DNA of "bad" bacteria, thereby stopping its reproduction. The discovery may assist in the development of treatments against antibiotic-resistant bacteria that cause infectious diseases.

Lung sonography is an useful guide to lung decongestion in HD patients at high CV risk

Eurekalert - Jun 07 2021 - 00:06
In hemodialysis patients at high cardiovascular risk, including patients with coronary artery disease and heart failure, lung congestion, a condition predisposing to decompensated heart failure and pulmonary edema, is much common. By means of ultrasound examination of the lungs, the degree of lung congestion can be estimated relatively easily, and the therapy aimed at lung decongestion can be adapted individually.

Dapagliflozin provides kidney protection even in cases of FSGS kidney disease

Eurekalert - Jun 07 2021 - 00:06
Many patients with the rare kidney disease FSGS require dialysis in the course of the disease, despite anti-inflammatory corticosteroid therapies. The DAPA-CKD study showed a significant benefit in renal outcomes for chronic kidney disease patients with and without diabetes mellitus, following treatment with dapagliflozin, an SGLT-2 (sodium dependent glucose co-transporter 2) inhibitor [1]. A subgroup analysis of the DAPA-CKD study [2] suggests that the beneficial effect of dapagliflozin extends to patients with FSGS.

Targeted COVID-19 therapy: What can we learn from autoimmune kidney diseases?

Eurekalert - Jun 07 2021 - 00:06
That viruses and bacteria can trigger autoimmune processes is well known. In autoimmune disease, the immune system attacks the body's own cells, which can become life-threatening, for example in lupus nephritis. In COVID-19, the same autoantibodies (antiphospholipid (aPL) antibodies) have been found repeatedly in lupus patients - a new study even describes a specific site of attack site where aPL antibodies could trigger a self-reinforcing continuous loop of autoantibody production and cause very severe COVID-19 courses.

COVID-19 as systemic disease: What does that mean for kidneys?

Eurekalert - Jun 07 2021 - 00:06
Renal tropism or virus detection can be associated with severe course, greater incidence of acute kidney injury (AKI) and earlier death - yet the immediate role of the virus in the kidney has not been clarified. An essential role in AKI is played by the overall combination of pneumonia/ARDS, cytokines and complement, ischemia hemodynamics and hypercoagulopathy/ microembolism. The high rate of AKI in COVID-19 patients is also conspicuous in comparison to other infectious diseases.

COVID-19: Long-term consequences for the kidneys can be expected

Eurekalert - Jun 07 2021 - 00:06
It was realized early on in the pandemic that kidney values can predict a severe COVID-19 course [1]. A new concern is that molecular tissue changes caused by the virus could lead in the long term to kidney injury, not only in COVID-19 patients who have suffered acute kidney injury, but also in those who have experienced renal dysfunction during acute disease. Kidney experts stress the importance of nephrological aftercare following COVID-19 illness.

Popularity runs in families

Eurekalert - Jun 07 2021 - 00:06
To investigate the role genes play in the evolution of social structure, Rice University researchers created an experiment they likened to the 1998 film 'The Truman Show.' Genetically identical versions of 20 fruit flies were placed in 98 controlled enclosures, and video cameras recorded their interactions. The study in this week's Nature Communications revealed the same clones occupied the same social positions in each enclosure, regardless of living conditions, providing evidence that popularity is heritable.

Bioinspired acid-catalyzed C2 prenylation of indole derivatives

Eurekalert - Jun 07 2021 - 00:06
Biomimetic catalysis is an emerging concept that emulates key features of enzymatic process. Prenylation is a ubiquitous process found in almost all living organisms. Inspired by the enzymatic mechanism, researchers developed a selective C2 prenylation of indoles via chemical catalysis, which can be applied to late-stage diversification of tryptophan-based peptides and concise synthesis of tryprostatin B.

A few common bacteria account for majority of carbon use in soil

Eurekalert - Jun 07 2021 - 00:06
Fewer than ten common bacterial taxa are responsible for the majority of soil carbon cycling, a team led by researchers at Northern Arizona University announced. The study, which used a technique quantitative stable isotope probing, identified several soil microbial groups that play an outsized role in carbon processing and CO2 release, and suggests that communities found in wild soil may contain functional redundancies.

Researchers identify a molecule critical to functional brain rejuvenation

Eurekalert - Jun 07 2021 - 00:06
A new study from a CUNY ASRC Neuroscience Initiative team has identified a molecule called ten-eleven-translocation 1 (TET1) as a necessary component in the repair of myelin, which protects nerves and facilitates accurate transmission of electrical signals. The discovery could have important implications in treating neurodegenerative diseases and for molecular rejuvenation of aging brains in healthy individuals.

Pandemic prevention measures linked to lower rates of Kawasaki disease in children

Eurekalert - Jun 07 2021 - 00:06
Rates of Kawasaki disease -- a condition that creates inflammation in blood vessels in the heart and is more common in children of Asian/Pacific Island descent -- have substantially decreased in South Korea during the COVID-19 pandemic.The decrease could be due to mask-wearing, hand-washing, school closures and physical distancing, suggesting Kawasaki disease may be prompted by infectious agents.The cause of Kawasaki disease is unknown, though it may be an immune response to acute infectious illness.

Applying mathematics takes 'friendship paradox' beyond averages

Eurekalert - Jun 07 2021 - 00:06
In network science, the famous "friendship paradox" describes why your friends are (on average) more popular, richer, and more attractive than you are. But a slightly more nuanced picture emerges when we apply mathematics to real-world data.

An 'atlas' of the brain's choroid plexus across the lifespan

Eurekalert - Jun 07 2021 - 00:06
Choroid plexus tissue, anchored in each of the brain's ventricles and bathed in cerebrospinal fluid, is a small but influential player in the brain. It's now been spatially inventoried with single-cell RNA sequencing, cataloguing its cell types and gene expression patterns in each ventricle during early development, adulthood, and old age.
