2-cell signaling Flashcards
1
Q
What is cell signaling?
A
communication between cells via chemical messengers
2
Q
4 main types of signaling?
A
- contact dependent
- paracine
- synaptic
- endocrine
3
Q
types of local signaling:
A
- autocrine
- contact dependent
- paracrine/synpatic
4
Q
which signaling is long distance?
A
endocrine
5
Q
what is paracrine signaling
A
cell responds to signaling molecules locally released by a signaling cell
6
Q
in paracrine signaling, what happens to ligands?
A
normally quickly degraded by enzymes/removed by neighboring cells
7
Q
what is autocrine signaling?
A
type of paracrine signaling where the signaling cell and the target cell are the same
8
Q
what is synaptic signaling
A
a specialized form or paracrine signaling, involving neurotransmitters as signals
