IMMUNOLOGY & INFLAMMATION MODEL

Collagen-Induced Arthritis (CIA) Mouse Model

The documented CIA platform uses DBA/1 mice and type II collagen immunization for rheumatoid-arthritis pharmacology studies involving T- and B-cell biology.

Documented efficacy programs include small molecules, degraders, and antibody-based interventions with serial clinical, immune, and histopathology readouts.

MODEL OVERVIEW

A data-rich arthritis model for immune-mediated pharmacology.

CIA studies in DBA/1 mice can combine longitudinal arthritis scoring and paw-thickness measurements with serum immunoglobulins, inflammatory cytokines, immune-cell profiling, and joint histopathology.

TYPICAL APPLICATIONS

What this model can support.

01

Therapeutic efficacy

Evaluate small molecules, degraders, antibodies, and other candidate interventions against arthritis progression.

02

Humoral response

Serial serum total IgG and anti-type II collagen IgG1 measurements can be incorporated into the study design.

03

Immune-cell profiling

Spleen FACS analysis can quantify T-cell, B-cell, myeloid, neutrophil, plasma-cell, and related immune populations.

04

Joint pathology

Histopathology workflows can include HE, TRAP, and Safranin O/Fast Green staining for joint and bone changes.

COMMON READOUTS

Readouts selected around the study question.

Endpoints are finalized with the selected model, species or strain, treatment design, and partner laboratory before study placement.

Disease activity

Arthritis score, body weight, and hind-paw thickness across induction and efficacy phases.

Immunoglobulins

Serum total IgG and anti-type II collagen IgG1 by ELISA.

Cytokines & FACS

Inflammatory cytokines and protocol-defined spleen immune-cell populations by flow cytometry.

Histopathology

HE, TRAP, Safranin O/Fast Green, and quantitative histology scoring where included.

The exact induction schedule, treatment window, reference arm, sampling plan, and pathology package are confirmed during technical review.
