Cell Communication

Cell Communication

1. Three Stages of signaling

   • Reception
     • Transduction
       • Response
     • G-Protein
       • vary in prtn types
     • Tyrosine Kinase
       • mbrn receptor atch P to tyrosines
     • Ion Channel
       • gate areas alw/block ions

2. local regulators

   • paracine
     • mult cells get/rct to mol
   • synaptic
     • elct sig trgs neurotrns mols carrying chem sig

3. long distance

   • hormones
     • cells rlse hrmn thru circ stm to target cells

4. intercellular receptors

   • in nucleus/cytplsm
   • hydrophobic
   • chem msnger thru plasma membrn
