Cell Signaling
An elective that follows the biochemistry course. It starts with the parts every pathway is built from, then takes the pathways one family at a time.
Unit 1 · How a cell knows anything
- Signals and How Far They Travel Cut every nerve to a loop of gut, drip acid on it, and the pancreas still answers. Who told it?
- Finding a Signal: NGF, EGF and the Bioassay A scrap of tumor, a chick nerve ganglion, and a halo of fibers in a day: how do you find a molecule you cannot see?
- Binding: Affinity, Occupancy and Dose–Response Naloxone reverses a morphine overdose without reacting with morphine at all. What are the two drugs competing for?
- A Field Guide to Receptors Acetylcholine starts a muscle twitch and slows a heart. Same molecule: what decides what it means?
- Circuits: Amplification, Feedback, Adaptation and Switches One photon changes a rod's current by about a picoamp. How does one molecule get that loud, and how does the cell make it stop?
