Monoclonal antibodies (mAbs) that focus on the spike protein of SARS-CoV-2 are effective in preventing the development of severe COVID-19. Omicron subvariants BQ.11 and XBB.15's successful evasion of neutralization by therapeutic monoclonal antibodies has prompted a recommendation against their use in treatment. However, the antiviral effects of administered monoclonal antibodies in patients are still poorly characterized.
A prospective analysis of 320 serum samples from 80 immunocompromised patients with mild to moderate COVID-19, treated with either sotrovimab, imdevimab/casirivimab, cilgavimab/tixagevimab, or nirmatrelvir/ritonavir, investigated the neutralization and antibody-dependent cellular cytotoxicity (ADCC) responses against the D614G, BQ.11, and XBB.15 variants. (1S,3R)-RSL3 A reporter assay was employed to measure live-virus neutralization titers and quantify antibody-dependent cellular cytotoxicity.
Only Sotrovimab's serum neutralization and ADCC activity is effective against the BQ.11 and XBB.15 strains of the virus. Relative to D614G, sotrovimab's neutralization capacity against the BQ.11 and XBB.15 variants is significantly diminished by 71-fold and 58-fold, respectively. However, a relatively minor reduction is observed in ADCC activity, decreasing by 14-fold for BQ.11 and 1-fold for XBB.15.
Our research indicates that sotrovimab demonstrates activity against BQ.11 and XBB.15 in patients who have received treatment, suggesting its potential as a valuable therapeutic option.
Sotrovimab, based on our findings, proves active against BQ.11 and XBB.15 variants in treated individuals, implying it may be a valuable therapeutic option for consideration.

A complete assessment of polygenic risk score (PRS) models for childhood acute lymphoblastic leukemia (ALL), the most frequent pediatric cancer, has not been performed. Existing PRS models for ALL were built on significant genetic locations found in genome-wide association studies (GWAS), in contrast to the demonstrably improved predictive capabilities of genomic PRS models for various complex diseases. While Latino (LAT) children in the United States are at the greatest risk for ALL, the potential for transferring PRS models to this particular demographic has not been studied. Our study involved the construction and subsequent evaluation of genomic PRS models, using GWAS data from non-Latino white (NLW) individuals or from a combined ancestry group. Held-out NLW and LAT samples exhibited comparable performance with the top PRS models (PseudoR² = 0.0086 ± 0.0023 for NLW and 0.0060 ± 0.0020 for LAT). The predictive accuracy of the LAT samples could be enhanced by conducting GWAS specifically on LAT samples (PseudoR² = 0.0116 ± 0.0026) or by including data from multi-ancestry samples (PseudoR² = 0.0131 ± 0.0025). While cutting-edge genomic models exist, their prediction accuracy does not surpass that of a conventional model utilizing all documented ALL-associated genetic markers in the available literature (PseudoR² = 0.0166 ± 0.0025), including locations from GWAS populations inaccessible for training our genomic PRS models. Our findings propose that expanded and more inclusive genome-wide association studies (GWAS) are critical for genomic prediction risk scores (PRS) to yield useful results for the entire population. Furthermore, the comparable performance across populations might indicate a more oligogenic architecture for ALL, where some loci with significant effects could be common to various populations. Upcoming PRS models, which abandon the supposition of infinite causal loci, may result in improved PRS performance for all.

The mechanism of membraneless organelle formation is thought to involve liquid-liquid phase separation (LLPS). The centrosome, central spindle, and stress granules exemplify such organelles. New research has brought to light that coiled-coil (CC) proteins, including the centrosomal proteins pericentrin, spd-5, and centrosomin, may possess the capacity for liquid-liquid phase separation (LLPS). CC domains exhibit physical features which could make them the driving force behind LLPS, but their direct participation in this process is unclear. We created a coarse-grained simulation platform to study the propensity for liquid-liquid phase separation (LLPS) in CC proteins, where interactions promoting LLPS stem only from the CC domains themselves. This framework indicates that the physical characteristics defining CC domains are sufficient to instigate protein liquid-liquid phase separation. To determine the influence of CC domain quantity and multimerization state on LLPS, a framework has been meticulously crafted. We find that phase separation occurs in small model proteins, each with a mere two CC domains. Increasing the concentration of CC domains, up to a maximum of four per protein, could partially improve the probability of LLPS. We find that trimer- and tetramer-forming CC domains show a dramatically greater tendency for liquid-liquid phase separation (LLPS) than dimer-forming coils. This indicates a more pronounced effect of multimerization on LLPS than the number of CC domains per protein. These findings, based on the data, provide support for the hypothesis that CC domains are responsible for protein liquid-liquid phase separation (LLPS), suggesting implications for future studies aimed at identifying the LLPS-driving regions in centrosomal and central spindle proteins.
The liquid-liquid phase separation of coiled-coil proteins has been hypothesized to be associated with the formation of membraneless cellular structures, including the centrosome and central spindle. The mechanisms by which these proteins undergo phase separation are poorly understood, especially regarding their specific properties. A modeling framework was developed to explore coiled-coil domains' potential role in phase separation, demonstrating their sufficiency in driving this process within simulations. Furthermore, we demonstrate the critical role of multimerization status in enabling these proteins' phase separation capabilities. The findings of this work suggest that the impact of coiled-coil domains on protein phase separation should be examined further.
Coiled-coil protein liquid-liquid phase separation is a suspected mechanism in the creation of membraneless organelles, including the centrosome and central spindle. The features of these proteins that could induce their phase separation are largely uncharted. We constructed a modeling framework to examine the possible part coiled-coil domains play in phase separation, and confirmed the sufficiency of these domains to drive this phenomenon in our simulations. We also demonstrate the critical role of multimerization status in the phase separation capabilities of these proteins. multiple infections This study highlights the potential significance of coiled-coil domains in protein phase separation.
