Infiltrating CD4⁺/CD45R⁺ cells do not express other BCR markers. A, Cells were analyzed for cell surface Igκ (B) and Igλ (C) expression using flow cytometry. CD45R⁺CD4⁺ cells did not express either Igκ or Igλ. However, some CD4⁻CD45R⁺ cells (B cells) were identified that expressed Igκ(B) or Igλ(C). Data shown are representative of four separate animals.
