- Squamous cell carcinoma antigen (SCCA) a magnetic enrichment-assisted core-satellite surface-enhanced Raman scattering (SERS) biosensor for ultrasensitive squamous cell carcinoma antigen (SCCA) detection is reported. Magnetic nanoparticles functionalized with SCCA capture antibodies act as enrichment cores, while 4-mercaptobenzoic acid (MBA)-encoded Au@Ag core-shell nanoparticles conjugated with SCCA detection antibodies serve as SERS satellites. Target-mediated sandwich immunorecognition induces a dynamically assembled core-satellite structure, bringing plasmonic nanogaps into close proximity and generating reproducible electromagnetic hot spots for signal amplification. Magnetic pre-enrichment and controlled assembly help reduce nonspecific protein interference in serum and contribute to stable signal generation. The biosensor exhibited a monotonic concentration-dependent Raman response over the range of 1 fg/mL to 10¹¹ fg/mL and achieved a limit of detection (LOD) of 60.0 fg/mL. Quantitative determination of serum samples was performed using an independently established matrix-matched calibration curve. The platform was further validated using real human serum samples from early-stage lung SqCC patients (n = 8) and healthy controls (n = 8), showing higher SCCA concentrations in patient samples than in healthy controls and clear discrimination between the two groups. Overall, the proposed magnetic enrichment-assisted core-satellite SERS immunoassay provides a robust analytical strategy for sensitive SCCA quantification in complex serum matrices. - Source: PubMed

Xiao HongpingWang XinyingXue SiqiWu ZhongyuanHuang RongjunFan MinChen YuanmeiFeng Shangyuan - Psoriasis is a chronic inflammatory autoimmune skin disease for which no standardised and reliable molecular biomarkers of disease course or activity are currently available. Here, we aimed to identify serum biomarkers of psoriasis. Serum samples from 40 patients with psoriasis and 40 healthy volunteers were analysed using ELISA and Proximity Extension Assay proteomics. ELISA revealed significantly increased serum levels of AGO2 and APOA1 in psoriatic patients versus controls, with a strong association between APOA1 and psoriasis (OR = 20.72, 95% CI of 4.57-93.87, = 0.000137). Targeted serum proteomics additionally identified 35 differentially expressed proteins, including well-known psoriasis drivers (e.g., top upregulated IL17A and SERPINB4). The most downregulated was adrenomedullin (ADM, FC = -10.12). For 14 altered proteins, no previous direct associations with psoriasis were reported. Among them, DEFB103A_DEFB103B and DSG3 showed the best discrimination between psoriasis and control samples, while SERPINB4 correlated with psoriasis severity. APOA1, DEFB103A_DEFB103B, and DSG3 emerge as novel candidate circulating psoriasis biomarkers, and SERPINB4 as a biomarker of psoriasis severity. The functional role of DSG3 and other newly identified proteins (ACRV1, HAO1, ADH4, GPD1, GFER, PTGES2, DSG3, AFAP1L1, GALNT3, RASGRP2, MAP2K6, LXN, NBEAL2, and VPS54) in psoriasis requires further studies. - Source: PubMed

We perform single-cell RNA sequencing of lesional (LAD) and non-lesional (NAD) skin from 42 AD patients and 23 healthy controls (HC). Keratinocytes (KCs) are the predominant disease-relevant cell type. In healthy skin, KC differentiation follows a linear trajectory from basal KCs through seven differentiated stages to terminal keratinized cells. In LAD, this process is disrupted, showing a reversed terminal transition mainly driven by DK7 cells. APOD, LYZ and SERPINB4 emerge as LAD-specific regulators linked to IL-13/IL-22 responses, ER stress and oxidative damage. Mitochondrial and ER dysfunction are specifically enriched in LAD DK6 cells, indicating a key pathogenic compartment. Spatial transcriptomics and cell-cell interaction analysis further identify LAD-specific TWEAK signaling from IL-13 Th2/cycling T cells to Fn14 basal/differentiated KCs. Here, we reveal disrupted KC differentiation and immune signaling circuits in AD, highlighting potential therapeutic targets. - Source: PubMed

Current methods for predicting LNM after surgery are limited, necessitating the identification of reliable biomarkers. This study aimed to evaluate the diagnostic value of serum squamous cell carcinoma antigen (SCC-Ag) combined with cytokeratin fragment 21-1 (CYFRA 21-1) for identifying long-term LNM after cervical cancer surgery. - Source: PubMed
