The role of amphipathic and cationic helical peptides in Parkinson's disease.

Peptides are attracting a growing interest for therapeutic applications in biomedicine. In Parkinson's disease (PD), different human endogenous peptides have been associated with beneficial effects, including protein aggregation inhibition, reduced inflammation, or the protection of dopaminergic neurons. Such effects seem to be connected to the spatial arrangement of peptide side chains, and many of these human molecules share common conformational traits, displaying a distinctive amphipathic and cationic helical structure, which is believed to be crucial for their activities.

Prognostic performance of early immune and endothelial activation markers in mild-to-moderate COVID-19 outpatients: a nested case-control study.

Introduction: Evidence on the association of biomarkers of host response to infection with COVID-19 clinical outcomes has focused mainly on hospitalized patients. We investigated the prognostic performance of 39 immune and endothelial activation markers measured early in the course of disease to predict the development of severe COVID-19 and hospitalization.

Methods: We conducted a nested case-control study from a randomized clinical trial evaluating the efficacy of COVID-19 convalescent plasma in outpatients aged 50 years or older presenting with mild-to-moderate COVID-19.

Resilience and emergence of pneumococcal serotypes and lineages in adults post-PCV13 in Spain: A multicentre study.

Background: Streptococcus pneumoniae causes invasive pneumococcal disease (IPD) in adults. The introduction of pneumococcal conjugate vaccines (PCVs) has reduced vaccine serotypes but has also led to the rise of non-vaccine serotypes. The aim of this study was to analyse pneumococcal lineages and their association with recent changes in IPD among adults in Spain.

A unique strain to study gastric cancer development.

colonizes a majority of the human population worldwide and can trigger development of a variety of gastric diseases. Since the bacterium is classified as a carcinogen, elucidation of the characteristics of that influence gastric carcinogenesis is a high priority. To this end, the Mongolian gerbil infection model has proven to be an important tool to study gastric cancer progression.

How AI Could Help Us in the Epidemiology and Diagnosis of Acute Respiratory Infections?

Acute respiratory infections (ARIs) represent a significant global health burden, contributing to high morbidity and mortality rates, particularly in vulnerable populations. Traditional methods for diagnosing and tracking ARIs often face limitations in terms of speed, accuracy, and scalability. The advent of artificial intelligence (AI) has the potential to revolutionize these processes by enhancing early detection, precise diagnosis, and effective epidemiological tracking.

The Role of Digital Rectal Examination for Early Detection of Significant Prostate Cancer in the Era of Magnetic Resonance Imaging.

The role of digital rectal examination (DRE) in the early detection of significant prostate cancer (PCa) is being questioned in the era of magnetic resonance imaging (MRI). However, some men with suspected PCa may still be identified solely through DRE, even with low serum prostate-specific antigen (PSA) levels. Additionally, most predictive models designed to improve significant PCa diagnostic pathways incorporate DRE findings.

Aggregating amyloid resources: A comprehensive review of databases on amyloid-like aggregation.

Protein aggregation is responsible for several degenerative conditions in humans, and it is also a bottleneck in industrial protein production and storage of biotherapeutics. Bioinformatics tools have been developed to predict and redesign protein solubility more efficiently by understanding the underlying principles behind aggregation. As more experimental data become available, dedicated resources for storing, indexing, classifying and consolidating experimental results have emerged.

Diverse genomic and epidemiological landscapes of redundant pbp5 genes in Enterococcus spp.: Insights into plasmid mobilization, ampicillin susceptibility, and environmental interactions.

Genetic redundancy in bacteria plays a crucial role in enhancing adaptability and accelerating evolution in response to selective pressures, particularly those associated with rapid environmental changes. Aminopenicillins like ampicillin are important therapeutic options for Enterococcus infections in both humans and animals, with resistance mostly associated with pbp5 gene mutations or overexpression. While the occurrence of redundant pbp5 genes has been occasionally reported, the advantages for the host bacteria have not been explored in detail.

Building Up Functional Coiled-Coil-Based Supramolecular Assemblies for Biomedical and Biotechnological Applications.

The self-assembling nature of coiled-coils has brought this common structural motif into the spotlight of protein design since it offers a customizable framework for engineering innovative protein nanoparticles with tailored functionalities. We recently harnessed the self-assembling capabilities of ZapB, a bacterial coiled-coil protein, to build up fluorescent protein nanoparticles possessing remarkable affinity for antibodies. Here, we describe a complete workflow detailing the design, production, and characterization of such coiled-coil-based protein nanostructures.

Reversion of metabolic dysfunction-associated steatohepatitis by skeletal muscle-directed FGF21 gene therapy.

The highly prevalent metabolic dysfunction-associated steatohepatitis (MASH) is associated with liver steatosis, inflammation, and hepatocyte injury, which can lead to fibrosis and may progress to hepatocellular carcinoma and death. New treatment modalities such as gene therapy may be transformative for MASH patients. Here, we describe that one-time intramuscular administration of adeno-associated viral vectors of serotype 1 (AAV1) encoding native fibroblast growth factor 21 (FGF21), a key metabolic regulator, resulted in sustained increased circulating levels of the factor, which mediated long-term (>1 year) MASH and hepatic fibrosis reversion and halted development of liver tumors in obese male and female mouse models.

The small molecule ZPD-2 inhibits the aggregation and seeded polymerisation of C-terminally truncated α-Synuclein.

Protein aggregation, particularly the formation of amyloid fibrils, is associated with numerous human disorders, including Parkinson's disease. This neurodegenerative condition is characterised by the accumulation of α-Synuclein amyloid fibrils within intraneuronal deposits known as Lewy bodies or neurites. C-terminally truncated forms of α-Synuclein are frequently observed in these inclusions in the brains of patients, and their increased aggregation propensity suggests a role in the disease's pathogenesis.
