So, cell signaling particularly occurs in four major types.
00:05
So, when we see the cell signaling types, we have the following.
00:09
So under cell signaling, the first one that comes is the contact dependent signaling.
00:15
Now, as the name says, it is a signaling that occurs when there is some sort of contact.
00:21
So, the signaling is dependent on the contact of the cells.
00:26
So that is about the contact dependent signaling.
00:28
Secondly, we have the paracrine signaling.
00:32
Now, when we speak about the paracrine signaling, this has the involvement of the paracrine in particular.
00:38
Thirdly, we have the synaptic signaling.
00:41
So, this is the third type of signaling followed by the last type of signaling, which is specifically called as the endocrine signaling.
00:50
Now, as the name suggests, this has an involvement of endocrine in order to have cell signals.
00:56
So, when we see about it in specific, we get the following gist out of it.
01:01
Now, particularly first one, that is contact dependent signaling, is the signaling that takes place when the signaling cells display a ligand or the ligand in particular on the surface and does not secrete it.
01:18
No physical connection or concentration particularly takes base, but the nearby cells, so there is signaling of cells that displays ligand on the surface written as s.
01:30
Nearby cells with the receptors written as r attack or attach directly to the ligand and cause the signaling in particular.
01:40
For example, juxtacrine signaling written as j .c.
01:45
Written as juxtacrine signaling, that is the contact dependent signaling...
