Immunoglobulin E, the potential accelerator of comorbid psoriasis and atherosclerosis.

Immunoglobulin (Ig) E is a key mediator in the induction and maintenance of allergic inflammation, characterized by a Th2-dominated immune response. Recently epidemiological studies have showed that elevated serum total IgE levels or an increased abundance of mast cells (MCs) at the lesion site are observed in psoriatic patients with cardiovascular diseases (CVD), such as atherosclerosis. Although the underlying mechanisms by which IgE synergizing with MCs in promoting these chronic immune-inflammatory diseases remain unclear, the interleukin (IL)-23/IL-17 axis appears to play a crucial role in comorbidity of psoriasis and atherosclerosis.

A highly sensitive and fast-response fluorescence nanoprobe for in vivo imaging of hypochlorous acid.

Fluorescent probes for in vivo hypochlorous acid (HClO) imaging often face challenges of low selectivity and high cytotoxicity, largely due to poor analyte recognition and water-insoluble aromatic skeletons. To address this, we synthesized fluorescein hydrazide by introducing a spiro-lactam unit into fluorescein, which offers high emission intensity and molar absorption. The five-membered heterocycle in fluorescein hydrazide is selectively disrupted by HClO, enhancing the conjugated system and electron delocalization of the fluorophore, resulting in highly sensitive fluorescence detection of HClO.

Regulating gypsum scaling-induced wetting in membrane distillation by heterogeneous crystallization: Role of filter media.

Mineral scaling and scaling-induced wetting are critical issues in membrane distillation (MD) during treatment of saline wastewaters. Gypsum scaling and scaling-induced wetting in MD were successfully regulated by heterogeneous crystallization with in-line granular filtration in this study. Stable water recovery increased from 32.

-Glucan-modified nanoparticles with different particle sizes exhibit different lymphatic targeting efficiencies and adjuvant effects.

Particle size and surface properties are crucial for lymphatic drainage (LN), dendritic cell (DC) uptake, DC maturation, and antigen cross-presentation induced by nanovaccine injection, which lead to an effective cell-mediated immune response. However, the manner in which the particle size and surface properties of vaccine carriers such as mesoporous silica nanoparticles (MSNs) affect this immune response is unknown. We prepared 50, 100, and 200 nm of MSNs that adsorbed ovalbumin antigen (OVA) while modifying -glucan to enhance immunogenicity.
