Okay, in order to answer this question, let's talk about iga.
00:04
Okay, that is an antibody that is secreted by plasma cells, like all antibodies.
00:10
Okay, so iga is expressed like on mucosal surfaces.
00:18
Okay, they are going to have this structure when they are secreted by in mucosal, well, this is going to be after they are secreted, but on mucosal surfaces, they are going to have a dimer arrangement.
00:33
It means like this.
00:37
But they are going to form dimers after they get to the surface of a tissues.
00:41
So iga accounts for more than two -thirds of the body's total immunoglobulin production.
00:47
And as i already said, they are going to have the function of mucosal surfaces protection.
00:54
So this iga is going to be useful as an important first line barrier limiting the access of intestine antigenes to the gut mucosa...
