Tetravalent antibodies are more potent and efficacious erythropoiesis‐stimulating agents than erythropoietin in vivo

open access: yesProtein Science, Volume 35, Issue 2, February 2026.
Abstract Recent studies have shown that tetravalent antibodies are potent and efficacious agonists of the erythropoietin (EPO) receptor (EPOR) both in vitro and in vivo. To identify antibody‐based erythropoiesis‐stimulating agents (ESAs) with therapeutic potential, we evaluated various tetravalent antibody formats for EPOR agonism and key biophysical ...

The secreted staphylococcal biofilm protein Sbp forms biomolecular condensates in the presence of DNA

open access: yesProtein Science, Volume 35, Issue 2, February 2026.
Abstract Staphylococcus epidermidis is the leading cause of device‐related infections, primarily due to its ability to form biofilms, surface‐adherent bacterial communities that confer remarkable resistance to antibiotics and host defenses. Small basic protein, Sbp, is a 16‐kDa protein expressed by S.

Filomicelle‐Embedded Composite Hydrogels for Localized Gelation Within the Anterior Chamber of the Eye

open access: yesSmall, Volume 22, Issue 7, 2 February 2026.
A composite hydrogel (C‐gel) incorporating PEG‐b‐PPS filomicelles enables localized in situ gelation and sustained nanocarrier release within the anterior chamber. The filamentous structure promotes spatial confinement of multi‐arm polymer crosslinking, even upon injection into large aqueous volumes, and gradually transitions into spherical micelles ...

Yogurt Fortification With Lyophilized Liposomes Coencapsulating Vitamins D3 and B12: Physicochemical Characterization, Sensory Evaluation and Static In Vitro Digestion

open access: yesJournal of Food Science, Volume 91, Issue 2, February 2026.
ABSTRACT Liposomes are lipid‐based delivery systems of interest in pharmaceutical, food, and nutraceutical industries due to their ability to encapsulate bioactive compounds, such as vitamins, improving stability, solubility, and bioavailability. This study aimed to develop functional yogurt enriched with vitamins D3 and B12 by encapsulating these ...

Selection for Postponed Senescence in Drosophila melanogaster Reveals Distinct Metabolic Aging Trajectories Modifiable by the Angiotensin‐Converting Enzyme Inhibitor Lisinopril

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
Assessment of oxygen consumption rates in young, middle‐aged, and old flies from the Drosophila B lines and long‐lived O lines revealed a significant increase in metabolic rate with aging only in B flies. Lisinopril prevented the age‐related rise in metabolic rate in B female flies.

Broad Epigenetic Shifts in the Aging Drosophila Retina Contribute to Its Altered Diurnal Rhythmic Transcriptome

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
As flies age, their photoreceptor transcriptome is extensively reprogrammed, with about 40% of genes undergoing rhythmic expression changes. These transcriptional changes are accompanied by altered RNA Polymerase II occupancy, chromatin accessibility, and H3K4 methylation, without major changes to the occupancy of the core clock transcription factors ...
