Quizplus · Accepted Answer

Clonal selection can be stimulated by both foreign and self antigens. The process of clonal selection involves the replication and selection of B cells, which occurs in response to stimulation by any antigen, whether it is foreign or self. However, in the case of self-antigens, there are additional mechanisms in place to prevent the activation of autoreactive B cells, which could lead to autoimmune diseases.
