…osis. Follow the pathway Dr. Purser discusses Th1 and Th17 cells, TNF-alpha, IL-6, IL-17, and oxidative stress around active lesions. He connects this with the blood–brain barrier and the energy demands of affected cells while separately d…

…the process of dissolving clots, alongside homocysteine and blood-vessel inflammation. These are interacting risk considerations; a common PAI-1 variant is not the same as having a clot or needing a blood-thinning treatment. Bring these qu…

Explore macrophage inflammatory protein-1 beta, CCR5, T cells, natural killer cells, and monocytes. Understand the connection CCL4, also called MIP-1 beta, is a chemical signal that attracts immune cells, particularly through CCR5. It is r…

…, from the outer surface of certain bacteria. It appears on cell surfaces and also circulates as soluble CD14. Follow the pathway Dr. Purser explains how CD14 works with MD-2 and TLR4 to activate inflammatory signals such as NF-κB. This co…

… panel can include immune messengers, chemokines that guide cell movement, receptors that receive signals, and proteins with other roles. These categories answer different questions. Follow the pathway Dr. Purser groups immune discussions …

…NA sequence; it is not a direct measurement of IFN-γ in the blood. Follow the pathway Dr. Purser connects regulatory variation with the Th1 immune pathway, macrophage activation, and inflammatory signaling. The exact allele and testing met…

…ollow 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 symptoms. Bring thes…

…, linking an initial danger response with downstream immune-cell activity. Bring these questions to your visit Ask which result is being discussed: a genetic variant, a measured protein level, or a diagnosed condition. How does it fit with…

…n the messenger, its component parts, and the receiver on a cell. IL-23 helps sustain Th17 activity, making it relevant to discussions of psoriasis, inflammatory bowel disease, and some inflammatory joint conditions. Bring these questions …

Explore epithelial alarmins, the ST2 receptor, ILC2 cells, IL-5, IL-13, and type 2 immunity. Understand the connection IL-33 is an alarm signal stored in some barrier cells. Injury or stress can release it, helping alert the immune system …

…osinophilic asthma and other eosinophil-related conditions. Blood eosinophil counts, clinical symptoms, and the underlying diagnosis matter when considering therapies aimed at IL-5 or its receptor. Bring these questions to your visit Ask w…

…on TLR2 is a pattern-recognition receptor that helps immune cells detect components of microbes and damaged tissue. It often works with TLR1 or TLR6. Follow the pathway Dr. Purser follows TLR2 signaling through MyD88 and NF-κB into cytokin…
