… Understand the connection CCL3, 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 t…

…nderstand the connection CCL5, also called RANTES, attracts immune cells through receptors including CCR1, CCR3, and CCR5. It participates in the normal response to infection and tissue injury. Follow the pathway Dr. Purser discusses CCL5 …

…13, also called BCA-1, helps guide B cells 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 g…

…ta is a type I interferon involved in antiviral defense and immune regulation. It is different from interferon-gamma, which belongs to the type II interferon group. Follow the pathway Dr. Purser discusses interferon-beta in the context of …

…rferon-gamma, or IFN-γ, is a type II interferon produced by immune cells including T cells and natural killer cells. It helps activate macrophages and organize defense against infection. Follow the pathway Dr. Purser connects the Th1 immun…

…thway Dr. Purser connects regulatory variation with the 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 diseas…

…regulation. Understand the connection IL-10 helps regulate immune responses and limit excessive inflammation. Its effects depend on which cells are involved and what is happening in the tissue. Follow the pathway Dr. Purser discusses IL-1…

…plains why the shared p40 subunit connects the Th1 and Th17 immune pathways. This also helps explain the difference between treatments that target p40 and treatments that target only the IL-23 p19 subunit. Bring these questions to your vis…

…es. Understand the connection IL-13 participates in type 2 immune signaling, including mucus production, allergic inflammation, and changes in barrier tissues. It works closely with IL-4 but is a distinct signal. Follow the pathway Dr. Pu…

…his receptor complex through MyD88 and NF-κB signaling into immune activity. A receptor-related variant and an IL-18 blood measurement answer different questions. Bring these questions to your visit Ask which result is being discussed: a g…

…and the IL-1 receptor response. This teaching also connects immune alarms with oxidative stress and explains why blocking a signaling pathway differs from supporting antioxidant defenses. Bring these questions to your visit Ask which resul…
