Document Summary
Categorizing by distance and by form of signal and receptor. The frequent role of small, monomeric g proteins. Cascades from plasma membrane to the nucleus. Virus have to stick to a cell before they can enter. Antibodies coat the virus, preventing them from entering the cell. Killer t-cell takes about a week to produce for a specific virus, directly communicates with cell (sending signal to cell that is instructing it) Organize cell signaling by describing by distance and delivery of signal. Synaptic signaling two cells almost in contact, one releases a diffusible substance. Endocrine signaling signal produced by any cell for any cell ( distributed throughout the body through bloodstream, distance can be far) Perocrine signaling local signaling, cells communicating with close by cells (larger distance than synaptic) Autocrine signaling cell producing signal may have receptor for the signal (self signaling) Killer t-cells can interact with juxtacrine signaling and synaptic signaling.
