Münster. Cerebrospinal fluid (CSF) protects the central nervous system (CNS) and analyzing CSF aids the diagnosis of CNS diseases, but our understanding of CSF leukocytes remains superficial. Here, using single cell transcriptomics, SFB researchers identify a specific border-associated composition and transcriptome of CSF leukocytes. In an article published in Nature Communications, they show that multiple sclerosis (MS) – an autoimmune disease of the CNS – increases transcriptional diversity in blood, but increases cell type diversity in CSF including a higher abundance of cytotoxic phenotype T helper cells. A new analytical approach, named cell set enrichment analysis (CSEA) identifies a cluster-independent increase of follicular T helper (TFH) cells potentially driving the known expansion of B lineage cells in the CSF in MS. In mice, TFH cells accordingly promote B cell infiltration into the CNS and the severity of MS animal models. Immune mechanisms in MS are thus highly compartmentalized and indicate ongoing local T/B cell interaction.

One drug – different effects: Metabolism of immune cells influences mode of action and could be an indicator for side effects
Muenster – One person can eat large amounts of pasta and still be a small dress size while another looks at a piece of chocolate and puts on weight: metabolism varies between individuals – and this goes beyond a subjective feeling. What is apparent in the overall organism also applies to each cell: the metabolism […]...more
