…al-thalamo-cortical circuits, dopamine, and inhibitory GABA signaling. He also explores behavioral therapy, medicines, and selected specialist interventions rather than reducing tics to one gene or nutrient. Bring these questions to your v…

…also called eotaxin-1, guides eosinophils toward tissues by signaling through CCR3. Eosinophils are immune cells involved in allergies and defense against some parasites. Follow the pathway Dr. Purser connects eosinophil recruitment with a…

…or MIP-1 alpha, helps call immune cells into tissue through receptors including CCR1 and CCR5. Normal recruitment supports defense and repair; persistent recruitment can contribute to inflammation. Follow the pathway Dr. Purser discusses m…

…ls toward organized immune structures. It works through the receptor CXCR5. Follow the pathway Dr. Purser explains how CXCL13 and CXCR5 help B cells and follicular helper T cells meet in lymph-node germinal centers. He connects ongoing act…

…Th1 immune pathway, macrophage activation, and inflammatory signaling. The exact allele and testing method matter when discussing a result, and an association does not establish disease. Bring these questions to your visit Ask which result…

…rent meanings. Follow the pathway Dr. Purser follows IFN-γ signaling into T-cell and macrophage activity and the relationship between inflammation and oxidative stress. A genotype needs to be considered alongside measured findings and symp…

…ser explains the relationship between IL-4, IL-13, and IL-4 receptor alpha. He discusses this pathway in allergic and eosinophilic conditions and distinguishes targeted medicines from the body’s antioxidant system. Bring these questions to…

…epair. It can signal through membrane-bound or soluble IL-6 receptors and the gp130 signaling protein. Follow the pathway Dr. Purser discusses classic signaling, trans-signaling, JAK/STAT3, and the liver’s production of C-reactive protein.…

…ses persist. Follow the pathway Dr. Purser connects TGF-β1 signaling with fibroblasts, collagen deposition, immune regulation, and oxidative stress. Its protective and harmful effects depend on tissue context, timing, and the rest of the i…

…e pathway Dr. Purser explains the connection between HMGB1, receptors such as RAGE and TLR4, NF-κB signaling, and ongoing tissue inflammation. He also discusses oxidative stress and the body’s antioxidant defenses. Bring these questions to…
