RNA‐Binding Protein RBM25 Targets the mRNA Stability of GTPase Rab22a to Restrict Viral Entry and Infection

Advanced Science, EarlyView.
This study identifies RNA‐binding protein RBM25 as a broad‐spectrum antiviral factor acting independently of type I interferon. It blocks viral entry by suppressing GTPase Rab22a via the RC3H1‐mediated destabilization of Rab22a mRNA. Viral downregulation of RBM25 enhances GTPase Rab22a expression and viral entry, revealing an unreported post ...

Microtiter Hemagglutination-Inhibition Assay for Staphylococcal Enterotoxin B [PDF]

Applied Microbiology, 1967
The rapid microtiter technique was investigated as a means of facilitating the detection of staphylococcal enterotoxin B. With this technique, many samples were assayed simultaneously, and readable results were obtained in 3 hr. Other advantages of this method, in addition to speed, were the small quantity of reactants used, ease of reading, and ...

Molecular Dynamics‐Guided Sterol Engineering of mRNA‐Lipid Nanoparticles Reprograms Biodistribution and Enhances Spleen‐Selective Immunity

Advanced Science, EarlyView.
Sterol engineering enables precise control of mRNA lipid nanoparticles by tuning membrane organization. Replacing cholesterol with bile acid‐derived sterols redirects protein expression from the liver to the spleen. Notably, CA‐20 LNP enhances antigen‐specific immune responses while exhibiting a favorable safety profile, highlighting sterols as a ...

Syphilis Seroprevalence and Associated Risk Factors in HIV-infected Individuals

Mediterranean Journal of Infection, Microbes and Antimicrobials, 2020
Introduction: Syphilis co-infection is common in patients living with human immunodeficiency virus (HIV)/AIDS due to the common route of transmission. In Turkey, both syphilis and HIV seroprevalences have been increasing in recent years. In our study, it

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Characterization and immunogenicity of nanoparticle vaccines displaying embecovirus spike proteins

Biotechnology Progress, EarlyView.
Virus‐like particle vaccines displaying spike proteins from OC43, HKU1 A, and HKU1 B were evaluated in mice for their ability to elicit antibodies against the spike proteins from OC43, HKU1 A, HKU1 B, and HKU1 C. Abstract Endemic human coronaviruses OC43 and HKU1 cause widespread respiratory infections and can be associated with severe illness in ...
