What does the Occludin and Claudin Antibodies IgG test measure?

Occludin and Claudin Antibodies IgG (TJ-IgG) is a clinical biomarker used in neurological-mental-health assessment. Occludin and claudins are transmembrane proteins integral to tight junctions in vascular endothelia, including those of the blood-brain barrier. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Occludin and Claudin Antibodies IgG?

Occludin and claudins are transmembrane proteins integral to tight junctions in vascular endothelia, including those of the blood-brain barrier. Tight junctions regulate paracellular permeability; their disruption has been implicated in barrier breakdown in models of neuroinflammation, stroke, and infection.

Why is Occludin and Claudin Antibodies IgG measured?

Antibodies to tight-junction proteins are measured as exploratory markers of blood-brain barrier compromise. The assay is not standardised across laboratories, and reactivity does not yet map to a specific disease diagnosis but may inform integrative treatment strategies aimed at reducing systemic inflammation.
