Contribution of long-lived plasma cells to antibody-mediated allograft rejection.

Persistent alloantigens derived from allograft tissues can be recognized by the host's alloreactive immune system. This process enables cognate B cells to differentiate into plasma cells, which secrete donor-specific antibodies that are key drivers of antibody-mediated allograft rejection. A subset of these plasma cells can survive for extended periods in a suitable survival niche and mature into long-lived plasma cells (LLPCs), which are a cellular component of humoral memory.

Evolving Treatment Landscape of Frontline Therapy for Metastatic Urothelial Carcinoma: Current Insights and Future Perspectives.

Cisplatin-based chemotherapy has long been the standard first-line (1L) treatment for metastatic urothelial carcinoma (mUC). However, up to 50% of patients with mUC may be ineligible for cisplatin owing to comorbidities, necessitating alternative primary treatment options. Immune checkpoint inhibitors (ICIs) have emerged as a vital alternative for those unable to receive cisplatin.

Methods: A retrospective cohort study was conducted with BD patients diagnosed according to ICD-10-CM codes F31.

Esophageal ILC2s mediate abnormal epithelial remodeling in eosinophilic esophagitis via Areg-EGFR signaling.

Eosinophilic esophagitis (EoE) is a chronic allergic disorder characterized by eosinophilia and epithelial thickening, resulting in dysphagia. While emerging evidence implicates increased frequencies of group 2 innate lymphoid cells (ILC2s) and increased interleukin (IL)-33 expression in EoE pathogenesis, the precise mechanisms remain unclear. In this study, we investigated the role of ILC2s in EoE pathogenesis.

Longitudinal multi-trajectory phenotypes of severe eosinophilic asthma on type 2 biologics treatment.
