Lymphoblastoid cell lines established from patients suffering from bipolar manic depression have been used to study the possible involvement of cation transport in the aetiology of this illness. No significant difference was found in the K+ fluxes mediated by the ouabain-sensitive sodium pump, the diuretic-sensitive cotransport system and the passive leak pathway of cell lines established from either control or bipolar subjects. The mean value for the specific binding of 3H-ouabain (sodium pump site number) was significantly higher in the bipolar group (approximately 30%) than in the control group.

Introduction: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a very rare disease, with unique diagnostic challenges and often dismal outcome. There are no widely accepted treatment guidelines available. Lymphoma-like regimens with or without autologous or allogenic transplantation were the cornerstone of most therapeutic concepts.

Introduction: Angioimmunoblastic T-cell lymphoma (AITL) is a rare and aggressive lymphoma with a poor prognosis. AITL is associated with Epstein-Barr virus (EBV)-positive B cells in most cases, suggesting a possible role for the virus in the pathobiology of AITL. Cell lines from AITL patients do not exist and models of human AITL are needed.

In this Highlights article, we present insights into the use of simple cell lines in neuroinflammation research, highlighting key findings from our recent investigations. Simple cell lines, including HEK, PC12, SHSY5Y, and N2a cells, provide valuable insights into critical signaling pathways and hidden facets of the neuroinflammatory landscape. Focusing on specific outcomes, including the impact of interleukin-6 (IL-6) and acid-sensing ion channels (ASIC1a), the study sheds light on neuroinflammatory processes.

Nanosafety assessment, which seeks to evaluate the risks from exposure to nanoscale materials, spans materials synthesis and characterisation, exposure science, toxicology, and computational approaches, resulting in complex experimental workflows and diverse data types. Managing the data flows, with a focus on provenance (who generated the data and for what purpose) and quality (how was the data generated, using which protocol with which controls), as part of good research output management, is necessary to maximise the reuse potential and value of the data. Instance maps have been developed and evolved to visualise experimental nanosafety workflows and to bridge the gap between the theoretical principles of FAIR (Findable, Accessible, Interoperable and Re-usable) data and the everyday practice of experimental researchers.
