Immune Cell Trafficking Pathway in Autoimmune Diseases - Visual Guide #2205000 (License: Personal Use)

The image depicts the systemic migration of immunoreactive T cells expressing integrin α4β1, originating in lymph nodes, entering circulation, and homing to inflammatory hubs before infiltrating target organs such as the brain (multiple sclerosis), pancreas (Type 1 diabetes), and gut (inflammatory bowel disease). Arrows indicate directional trafficking, with labeled anatomical structures and molecular markers clarifying pathogenic pathways in autoimmunity.

Used in medical education, patient-facing autoimmune disease resources, or clinical research pages to explain T-cell-mediated pathogenesis; matches user intent for understanding disease mechanisms or immunotherapy targets.
