Beyond eosinophil depletion: long-term clinical trajectory and durability of response to benralizumab in patients with severe eosinophilic asthma and CRSwNP: an 18-month real-world study (the BANDOR study)

BackgroundThe management of patients with severe eosinophilic asthma and chronic rhinosinusitis with nasal polyps requires therapies capable of inducing stable remission. While benralizumab is an established treatment for severe asthma, randomized cont…

Single-cell transcriptome sequencing analysis of peripheral blood mononuclear cells reveals immune signatures in patients with polymyalgia rheumatica

BackgroundPolymyalgia rheumatica (PMR) is an auto-inflammatory disease or autoimmune disease that involves multiple immune cells. In this study, single-cell transcriptome sequencing (scRNA-seq) combined with cellular communication analysis were used to…

Efficacy and safety analysis of consolidation immunotherapy following definitive concurrent chemoradiotherapy for locally advanced esophageal squamous cell carcinoma

BackgroundDefinitive concurrent chemoradiotherapy (dCRT) is standard for locally advanced esophageal squamous cell carcinoma (ESCC), but recurrences remain common. Evidence for consolidation immunotherapy after dCRT is limited. This study evaluated the…

Serum and cerebrospinal fluid biomarkers for risk stratification of hospitalized neonates and young infants with suspected serious bacterial infections: a secondary analysis of a prospective cohort study

BackgroundImproved risk stratification strategies for neonates and young infants are urgently needed to reduce the substantial mortality burden associated with infectious diseases, particularly in low- and middle-income settings. Evidence supporting th…

Targeting TLR4 alleviates the progression of experimental autoimmune encephalomyelitis by regulating central resident cells and Th1/Th17 cell differentiation

Multiple sclerosis (MS) is an autoimmune demyelinating disease characterized by neuroinflammation. Toll-like receptor 4 (TLR4) is a receptor for damage-associated molecular patterns, such as high-mobility group box 1 (HMGB1) and plays a role in innate …

Impaired immune surveillance exposes the germinal center as a niche for gammaherpesvirus-associated B cell lymphomagenesis

BackgroundGammaherpesviruses establish lifelong latency in B cells and are linked to multiple human lymphoid malignancies, including Epstein-Barr virus (EBV)–associated lymphomas that arise at significantly increased frequency in settings of impaired i…

Add-on sirolimus in refractory iMCD-TAFRO: a TAFRO-enriched 8-patient case series with paired single-cell profiling

IntroductionAnti–IL-6 therapy with tocilizumab (TCZ) is ineffective in a proportion of patients with idiopathic multicentric Castleman disease (iMCD), particularly the TAFRO subtype, and rescue options remain limited. Evidence for mTOR inhibition comes…

Fetal bovine and calf serums differ in their contents of endocannabinoids, unsaturated fatty acids, monoacyl-glycerols, N-acyl-ethanolamines, oxylipins, and cytokines

Cell culture relies heavily on serum supplementation, but serum composition makes it difficult to ensure reproducibility and consistency of experimental results. Consequently, research10 groups must test multiple batches to ensure the functionality and…
