Rabbit Cells

Postby Condraz23 » Sat Oct 14, 2006 11:21 pm

Physiologically, rabbit cells and human cells are very similar. Therefore, how does the body realize that rabbit cells do not belong in the body?

Thanks.

I believe that there is no identical structure of every single cell from different species, even from a species, even from an individual. For example, spermatozoon is recognized as foreign cell by immuno-competent cells because these cells never "see" spermatozoa during their education or antigen-dependent maturation.

Thus, rabbit cell, whatever it is, will be a foreign one to human body. That's why we can yield human antibodies or antisera from rabbit. If rabbit cell is recognized as self-cell, the exposure will generate immuo-tolerance, we cannot yield anything.

The recognition process can be done by pattern-recognition mechanism or protein-surface identification by MHC.
