Cell Communication: 2 Types
Definition

1. Direct Contact

a. Small molecules move between cells

b. Extracellular cell-cell recognition, matching of receptors (cell contacts target cell)

 

2. Communication through signaling molecules

A. Local (short distance)

a. Paracrine (growth factors) (molecules that affect nearby cells because they are taken up quickly before they die)

b. Synaptic (neurotransmitters)

B. Long distance

a. Endocrine (hormones sent)

-Steroid hormones are lipids, thus they can go through the lipid bilayer unhindered. The hormones then bind to receptors in the cytosol, the hormone-receptor bond then binds to the DNA inducing change in the gene activity

 

Signaling: 3 stages

1. Reception  2. Transduction  3. Response

=activation of cell response, a gene is turned OFF or ON

 

Amplification-just one cell sending a signal can be amplified to make a lot happen in the body, and quickly
