  1. B cell contact antigen → helper T cell is activated → clonal selection occurs

  2. body cell becomes infected with a virus → new viral proteins appear → class I MHC molecule-antigen complex displayed on cell surface

  3. self-tolerance of immune cells → B cells contact antigen → cytokines released

  4. complement is secreted → B cell contacts antigen → helper T cell activated → cytokines released
