BSAVA Petsavers Article: Validation of an ELISA assay for measurement of the metabolite of serotonin, 5‐hydroxyindole acetic acid (5‐HIAA), in canine urine

Journal of Small Animal Practice, EarlyView.
Objectives Serotonin (5‐hydroxytryptophan), implicated in a number of canine diseases, has a very short half‐life in the serum. Urine concentration of its breakdown product 5‐hydroxyindole acetic acid after an 8 hour fast is a more reliable measure of circulating serotonin in humans.

Spatial and multi‐omic profiling reveals pericyte‐derived CCL19 as a key prognostic factor in CNS lymphoma

HemaSphere, Volume 10, Issue 6, June 2026.
Abstract Biological mechanisms underlying clinical heterogeneity in central nervous system lymphoma (CNSL) are largely unknown. While previous studies suggest the chemokine CLL19 as a crucial factor for the formation of CNSL in murine models, its role in human disease remains elusive.
