How Dr. Purser combines inherited tendencies, current nutrient findings and conventional laboratory results without treating them as the same test.

Follow Dr. Purser’s teaching on folate, B12, sulfur pathways and antioxidant support around homocysteine.

Understand why Dr. Purser teaches glutathione, SOD and catalase as a connected antioxidant team.

Encodes the reduced folate carrier, a protein involved in transporting folates into cells.

ALPL encodes tissue-nonspecific alkaline phosphatase, an enzyme important to bone and tooth mineralization and vitamin B6 metabolism. Persistently low alkaline phosphatase can deserve a different evaluation from a general nutrient deficiency.

CCL11 encodes eotaxin-1, a chemokine best known for attracting eosinophils. Its receptor relationships connect it to allergic inflammation as well as broader research into immune signaling.

CCL2 encodes MCP-1, a chemokine that attracts monocytes toward sites of immune activity. Recruitment is a different task from the cytokines that activate those cells once they arrive.

CCL3 encodes MIP-1 alpha, a chemokine involved in attracting and activating immune cells. It is related to CCL4, or MIP-1 beta, but the two genes and proteins are distinct.

CCL4 encodes MIP-1 beta, a chemokine involved in attracting immune cells. It participates in a recruitment network that includes CCL2, CXCL8 and related chemokines.

CCL5, also called RANTES, is a chemokine that helps direct immune-cell movement. Chemokines tell cells where to go, which is different from measuring the total strength of an immune response.

CD40 encodes a receptor that participates in communication between immune cells, including T-cell help for B-cell responses. Its partner is CD40 ligand, encoded by CD40LG.
