- Asthma is a chronic inflammatory disease affecting over 300 million people worldwide. This disease has multiple underlying etiologies, and a major endotype of asthma is characterized by cellular and molecular signatures of type 2 (allergic) inflammation. In this study we conducted bronchoscopies with airway segmental allergen challenge in allergic asthmatics to dissect airway responses to allergen. Using mass cytometry and single-cell RNA sequencing, we characterized with high resolution the airway immune landscape before and after allergen challenge and the heterogeneity present between subjects. This heterogeneity generally falls along a type 1/ type 2 axis. In type 2 high individuals, we identified allergen-reactive Th2 cells by using TCR sequences to barcode clonal T cell populations in single-cell genomic and activation-induced marker expression assays. These potentially pathogenic Th2 cell clones were present systemically and expanded following allergen challenge, connecting local lung inflammation to systemic clonal Th2 cell dynamics. Th2 cell airway ingress was coordinated with myeloid cell expression of T cell chemoattractants including CCL17 and CCL22. This study provides insight into the molecular and cellular components of allergen-induced tissue inflammation in asthma. Deeper resolution of the T cell response to aeroallergens may inform novel diagnostic and therapeutic strategies for asthma and other allergic airway diseases. - Source: PubMed

CSF leukocytes as an inflammatory marker have not been explored in HD. We explored high-precision CSF-leukocyte counts across different HD stages in the multicenter prospective biosample HD study HDClarity and their association with CSF neurofilament light chain (NFL) and cytokine and chemokine patterns. - Source: PubMed

Gao YuÁsbjörnsdóttir BirnaVinther-Jensen TuaVon Essen Marina RodeHellem Marie Nathalie NickelsenHjermind Lena EEjlerskov PatrickLandwehrmeyer G BernhardSellebjerg FinnNielsen Joergen ErikLewerenz Jan - Plant-derived compounds can be transformed by the human gut microbiota into postbiotic metabolites with distinct structures and biological activities, providing insight into the mechanisms underlying the pharmacological effects of medicinal plants. Among them, 5-(3',4'-dihydroxyphenyl)-γ-valerolactone (DHPV), a microbial metabolite of procyanidins, has emerged as a promising bioactive molecule with therapeutic potential. This study evaluated the potential application of synthetically produced DHPV in inflammatory conditions, focusing on its effects on inflammatory responses and wound-healing processes in skin and mucosal cell models, including keratinocytes, dermal fibroblasts, and vaginal epithelial cells. Cell viability after DHPV treatment was assessed using the MTT assay. Anti-inflammatory activity was examined in TNF-α/IFN-γ-stimulated HaCaT keratinocytes, LTA-stimulated NHDF fibroblasts, and TNF-α-stimulated VK2 vaginal epithelial cells. The effect on wound healing was evaluated using a keratinocyte scratch assay, while LC-MS-based metabolomic profiling was performed in TNF-α/IFN-γ-stimulated HaCaT cells. DHPV significantly reduced the release of pro-inflammatory mediators in all tested models, including IL-6, IL-8, CCL2, CCL22, and CCL5 in HaCaT keratinocytes; CCL2, IL-6, and IL-8 in NHDF fibroblasts; and IL-8 in VK2 cells. DHPV showed a favorable safety profile at the tested concentrations and markedly enhanced keratinocyte migration, indicating pro-regenerative activity. Metabolomic analysis revealed effects on tyrosine, histidine, and tryptophan metabolism, pathways related to cell proliferation, migration, and antioxidant defense. Overall, DHPV demonstrated anti-inflammatory and pro-healing properties, supporting its potential as a bioactive compound for inflammatory skin and mucosal conditions. - Source: PubMed

This study aimed to investigate the effects of Leishmania tropica, the main agent of cutaneous leishmaniasis (CL) in Türkiye, on the polarization of primary human macrophages. Primary monocytes were isolated from human peripheral blood and differentiated into macrophages using GM-CSF. The cells were infected with L. tropica promastigotes, analyzed after 48 h. Polarization was evaluated through morphological changes, flow cytometry for surface markers (CD80, CD163, CD206, CD209), and qPCR for gene expression of M1 (NOS2, IDO1, IRF4) and M2 (ARG1, CCL22, CCL1) markers. An infection rate of 56.5% was achieved, with infected macrophages shifting from a spindle-like morphology to a rounded and granular appearance. Flow cytometry revealed a significant decrease in the expression of M1 marker CD80 and M2 markers CD206 and CD209 (p < 0.01), while CD163 expression showed a non-significant increase. qPCR analyses demonstrated a significant down regulation of M1-related genes and a significant upregulation of the M2-related gene ARG1 (p < 0.05). The findings suggest that L. tropica infection induces a shift in macrophage polarization from an M1-like phenotype toward an M2-like phenotype, with partial resemblance to an M2c-like profile, though the concurrent decrease in CD206 and CD209 underscores the complexity of the phenotype and indicates that the activated state does not conform neatly to any single M2 subtype. This shift likely serves as an immune escape strategy, promoting parasite persistence and influencing the chronicity of CL. Further studies incorporating additional M2c subtype markers, multiple time points, and functional assays are needed. - Source: PubMed

Taymaz NevinAl-Omar AhmedAlizadeh HamidAsadi MiladÖzbilgin AhmetÖzbel YusufTöz Seray - Topical postbiotic emollient (Strain CX) has shown efficacy for mild-to-moderate atopic dermatitis (AD) in a previous study; however, treatment responses according to allergic comorbidity status have not yet been explored. We conducted a analysis to evaluate the differential therapeutic effects of Strain CX in patients with AD stratified by the presence or absence of allergic comorbidities. This analysis was derived from a randomized, double-blind, vehicle-controlled trial (Clinical Research Information Service of South Korea, KCT0007876). A total of 98 patients with mild-to-moderate AD were stratified into placebo (n = 33), AD without allergic comorbidities (n = 29), and AD with allergic comorbidities (n = 36) groups. The primary outcomes were the Investigator's Global Assessment (IGA) score and the proportions of participants achieving 25% or 50% improvement in the Eczema Area and Severity Index (EASI), assessed at weeks 4 and 8. The secondary outcomes included a range of skin-related clinical and molecular measures, along with additional evaluations of serum inflammatory and allergic biomarkers as laboratory measures in the per-protocol analysis set. At week 8, 55.2% (16/29) of participants in the AD without allergic comorbidities group achieved an IGA score of 0 or 1 with ≥ 1 point reduction, compared to 30.6% (11/36) in the AD with allergic comorbidities group ( = 0.0272). Both Strain CX intervention groups showed significant improvements in skin parameters, including EASI, skin moisture, and transepidermal water loss. Notably, the AD with allergic comorbidities group solely exhibited significant reductions in systemic inflammatory markers, including sIL-2R (mean, -231.19; 95% confidence interval [CI], -378.82 to -83.57 pg/mL), CCL17 (-127.05; 95% CI, -251.80 to -2.31 pg/mL), and CCL22 (-578.40; 95% CI, -939.31 to -217.49 pg/mL). Clinical skin responses improved more in patients with AD without allergic comorbidities, while immunomodulatory benefits were observed in those with allergic comorbidities. These findings support patient stratification based on allergic comorbidity status for personalized Strain CX treatment strategies.
