Why some antigens will only induce response resulting in IgM antibodies?

Responses against highly conserved mammalian proteins are often weak and mailny resulting in IgM antibodies, owning to lack of stimulation of T cells (Goding 1993). However, there are also exceptions. In case of conserved mammalian antigens, use a species which is more distant evolutionary e.g. Hens.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
