Passive transfer of immune protection against tumor growth with CD4+ T cells. Recipient mice were inoculated with ID8 tumor cells on the day after cell transfer. Growth of ID8 tumors was inhibited in mice transferred with AMHR2-CD-specific (a) LNCs and (b) splenocytes. (c) At 190 days after splenocyte transfer and inoculation, mean tumor weights were lower in recipients of AMHR2-CD-specific splenocytes compared to recipients of OVA-specific splenocytes. Transfer of purified AMHR2-CD-specific (d) CD4+ T cells but not (e) B220+ B cells inhibited ID8 tumor growth. Asterisks indicate statistical significance. Error bars show ±SE.
