Functionalized aluminum hydroxide-based self-adjuvanted nanovaccine orchestrates antitumor immune responses via Dectin-1 signaling.

Self-adjuvanted vaccine delivery platforms possess potential for targeted delivery of antigens and initiation of potent immune responses. Although aluminum-containing adjuvants have been approved and widely used in human vaccines, their effectiveness in inducing Th1-type immune responses is far from satisfactory. To facilitate antigen delivery and activate potent antitumor immune responses, a self-adjuvanted nanovaccine (CPBG-Al@OVA) is constructed by functionalizing aluminum hydroxide with β-1,3-glucan, which recognizes pattern recognition receptors via Dectin-1.

OMVs have been recognized as potent natural immune adjuvants and drug delivery vehicles. Photothermal therapy that triggers immunogenic cell death further stimulates the immune system by releasing damage-associated molecular patterns.

Cognitive impairment in the schizophrenia spectrum: exploring the relationships of the g-factor with sociodemography, psychopathology, neurodevelopment, and genetics.

Background: Cognitive impairment constitutes a prevailing issue in the schizophrenia spectrum, severely impacting patients' functional outcomes. A global cognitive score, sensitive to the stages of the spectrum, would benefit the exploration of potential factors involved in the cognitive decline.

Methods: First, we performed principal component analysis on cognitive scores from 768 individuals across the schizophrenia spectrum, including first-degree relatives of patients, individuals at ultra-high risk, who had a first-episode psychosis, and chronic schizophrenia patients, alongside 124 healthy controls.

Serum metabolic profiles in quails: Effects of age, breed, and sex.

Over the past decade, metabolomic research in livestock and poultry has gained considerable momentum; however, quail metabolomics still lags behind that of livestock species such as chickens, pigs, and cattle. Quails are important models due to their low-cost protein sources-both eggs and meat-and practical benefits such as minimal space requirements, high egg production, disease resistance, and rapid reproduction. Therefore, it is necessary to systematically understand the effects of various factors on quail metabolism to provide a theoretical basis for accurate feeding and breeding practices.

Glycoengineered extracellular vesicles released from antibacterial hydrogel facilitate diabetic wound healing by promoting angiogenesis.

Diabetic wounds have become a global healthcare burden owing to impaired angiogenesis and persistent infections. Extracellular vesicles (EVs) can improve diabetic wounds, though their targeting ability is limited. In this study, we investigated the performance of a novel hydrogel dressing comprised of gelatin methacryloyl, glycoengineered EVs, and polylysine in treating infected diabetic wounds.
