  1. HELLO! Cell-Cell Interactions! HOWDY!

  2. Communicating with your neighbors:Cell-Cell Gaps

  3. Communicating with your neighbors:Cell-Cell Gaps

  4. We’re getting dehydrated! Communication between distant cells I wonder if I should pee out this water or save it?

  5. Communication between distant cells Hormones!

  6. “Hormones are like a fleeting scent or whispered phrase from someone you are attracted to – a tiny signal, but one that makes your cheeks flush and your heart pound”

  7. We’re getting dehydrated! STEP 1: Signal Reception Okay got it! Huh?

  8. Let’s get ready to fight! (or run away!)

  9. Signal Reception • Ligand = • Signal Receptor =

  10. Signal Reception • Receptors are dynamic! • Receptors can be blocked!

  11. STEP 2: Signal Processing (Transduction)

  12. Signal Transduction via G-Protein • G protein = SIGNAL RECEPTOR ENZYME

  13. Signal Transduction via Enzyme – Linked Receptors

  14. Signal Transduction via Enzyme – Linked Receptors

  15. Signal Response

  16. Unicellular Organisms Vibrio Fisheri

  17. Unicellular Organisms Pseudomonas aeruginosa

  18. Cell Communication Breakdown http://learn.genetics.utah.edu/content/begin/cells/badcom/
