Pioneering Tissue Research in Childhood Arthritis

TRICIA is a UK-wide collaborative network advancing research into juvenile idiopathic arthritis through minimally invasive tissue sampling and cutting-edge analytics.

Our Research

Understanding inflammation in childhood arthritis through tissue-based research

TRICIA supports a programme of clinical and translational research in juvenile idiopathic arthritis (JIA), with a focus on synovial tissue sampling and analysis. Our aim is to enable precision pathology through the integration of clinical data, laboratory findings, and patient experience.

What We Study

Our research explores the cellular and molecular mechanisms underpinning inflammation in JIA. This includes:

We use a combination of minimally invasive ultrasound-guided biopsies, histology, spatial omics, and advanced bioinformatics.

How We Work

TRICIA facilitates research across multiple NHS sites, supported by:

  • Standardised biopsy protocols and data pipelines

  • Shared access to tissue and data platforms

  • Integration with national research initiatives (e.g. CLUSTER, IMID-Bio)

  • Patient and public involvement in design, review, and communication

Our infrastructure supports both discovery science and translational research aligned with clinical need.

MAPJAG

MAPJAG is our clinical observation study exploring how inflammation in the joints and gut is connected in children with JIA. It is a non-interventional study using ultrasound-guided biopsies and gut sampling to investigate immune responses and microbial profiles.

This study supports:

  • Tissue sample collection at multiple time points

  • Integration with spatial transcriptomics and microbiome profiling

  • Recruitment from paediatric rheumatology centres across the TRICIA network
