Exam 9: Cytokines

Matching The tumor necrosis factor (TNF) family of proteins includes several soluble and membrane proteins that share structural homologies. All members of this family bind to members of the TNF-receptor family of molecules expressed on cell surfaces. TNF-R family members are structurally homologous to one another and utilize similar signal transduction pathways. For each description of a TNF or a TNF-R family member in questions , select the term listed in options A-E that best matches it. -Expressed on many cells types, its cytoplasmic tail includes a death domain, binds TNF-receptor associated death domain (TRADD), and initiates a pro-apoptotic signaling cascade.

For each of the following descriptions of a chemokine or chemokine receptor, select the chemokine or chemokine receptor (A-G) that most closely matches it. -Important in dendritic cell and T cell localization in lymph nodes
