IL22

IL22 encodes a cytokine that acts on tissues such as epithelial barriers. It can support barrier defense and repair, while its effects depend on the tissue and inflammatory setting.

THE TEACHING CONNECTION

Barrier defense, repair and excess tissue growth

Barrier defense, repair and excess tissue growth

IL22 encodes a cytokine that acts on tissues such as epithelial barriers. It can support barrier defense and repair, while its effects depend on the tissue and inflammatory setting.

How Dr. Purser connects the pieces

Dr. Purser discusses IL-22 in mucosal protection, psoriasis, ulcerative-colitis and pregnancy-related inflammatory contexts. These different roles explain why simply describing a cytokine as good or bad is incomplete. A variant cannot establish barrier failure or predict a pregnancy complication.

Where the VARS Triad and MTHFR Daily fit

In Dr. Purser’s treatment framework, the VARS Triad—VARS Glutathione, VARS SOD and VARS Catalase—together with MTHFR Daily is a central consideration when homocysteine or cytokine issues are involved. He emphasizes VARS Glutathione as a foundational functional-support component across his genetic SNP teaching. The individual gene lesson explains how its pathway connects to that broader approach.

This describes the Purser treatment model, not proof that a product corrects a variant or treats every associated condition. Product choice, formulation, sequence and amount depend on the individual assessment, existing medicines, current findings and tolerance.
