…DMA), nitric oxide, blood vessels, and related blood-vessel pathways. Understand the connection DDAH1 is an enzyme that helps break down asymmetric dimethylarginine, or ADMA. ADMA can interfere with nitric oxide production, which matters f…

… T lymphocytes, biologic therapies, and related antioxidant pathways. Understand the connection Interferon-gamma, or IFN-γ, is a type II interferon produced by immune cells including T cells and natural killer cells. It helps activate macr…

…, genomic stability, and related DNA-repair and antioxidant pathways. Understand the connection RAD50 is a DNA repair protein, not a cytokine. It forms the MRN complex with MRE11 and NBS1, helping cells recognize and respond to double-stra…

…oxin exposure from questions about genetics and antioxidant pathways. How the pieces connect Lead, mercury, arsenic, and some pesticides are exposures that require an exposure history and appropriate testing. A gene result does not show th…

…athway helps support Th17 immune cells and their downstream cytokines, including IL-17. Follow the pathway Dr. Purser connects IL-23 receptor signaling with inflammatory bowel disease, psoriasis, and inflammatory joint pathways. Targeting …

…m. Your body normally recycles it through several metabolic pathways that require nutrients like: Vitamin B6 Vitamin B12 Folate Serine Glutathione When those pathways work properly, homocysteine stays in balance. But when the system becomes…

… Dr. Purser connects TNF-alpha, IL-1 beta, IL-6, and T-cell pathways with local tissue inflammation. He emphasizes that inflammatory signaling differs with the underlying condition, which is why symptoms alone cannot identify the cause. Br…

…Purser includes IL23R in his inflammatory bowel disease and psoriasis teaching. The gene, the cytokine IL-23 and the downstream cytokine IL-17A are related but distinct. An inherited marker does not measure receptor function in your tissues…

…ad and MTHFR Daily fit If you are exploring homocysteine or cytokines, Dr. Purser may discuss MTHFR Daily and the VARS Triad: VARS Glutathione, VARS SOD, and VARS Catalase. He gives glutathione a central place in his approach to antioxidant…

…stand the connection IL-1 beta, or IL1B, is an inflammatory cytokine that is activated through processes including the NLRP3 inflammasome and caspase-1. It participates in fever and the recruitment of immune cells. Follow the pathway Dr. P…

…R5 is a receptor on cells, rather than a freely circulating cytokine. It receives the CXCL13 signal and helps direct B cells and follicular helper T cells. Follow the pathway Dr. Purser connects this navigation system with germinal centers…

…eaching connects IL-10 with macrophages, T cells, and other cytokines instead of labeling every cytokine as simply good or bad. Bring these questions to your visit Ask which result is being discussed: a genetic variant, a measured protein …
