Antigens and “foreignness”

Antigens and “foreignness”

Antigens and “foreignness”. Antigens (or, more properly, immunogens ) have a series of features which confer immunogenicity. One of these features is “foreignness.” So, we can infer that – most often – antigens – ultimately – originate externally.
