… other roles. These categories answer different questions. Follow the pathway Dr. Purser groups immune discussions around signals such as IL-6, TNF-alpha, IL-1 beta, IL-17, IL-23, and interferons. CCL2/MCP-1 and IL-8/CXCL8 are chemokines; …

… which matters for the normal relaxation of blood vessels. Follow the pathway Dr. Purser follows ADMA, nitric oxide synthase, endothelial function, and oxidative stress. DDAH1 is not a cytokine, even when it appears in a discussion of vasc…

…tivate macrophages and organize defense against infection. Follow the pathway Dr. Purser connects the Th1 immune response with macrophage activation, antigen presentation, and inflammation. He discusses the interaction of IFN-γ with TNF-al…

…nce; 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 method matt…

… same gene can have many variants with different 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 con…

…ch cells are involved and what is happening in the tissue. Follow the pathway Dr. Purser discusses IL-10 promoter variants and the balance between immune defense and regulation. This teaching connects IL-10 with macrophages, T cells, and o…

… IL-12 combines p40 with p35; IL-23 combines p40 with p19. Follow the pathway Dr. Purser explains why the shared p40 subunit connects the Th1 and Th17 immune pathways. This also helps explain the difference between treatments that target p…
