Popis: | Murine lupus in NZB/NZW ( B W ) mice is characterized by immune-complex glomerulonephritis and lymphocytic infiltration of several organs, including the kidney. We recently showed that treatment of B W mice with F(ab′)2 anti-CD4 monoclonal antibody retards autoimmunity by inhibiting the function of CD4+ cells and not by depleting them. To determine if treatment with F(ab′)2 anti-CD4 prevented lymphocytic infiltration of kidneys or simply inhibited the function of the infiltrating lymphocytes, long-term survivors of treatment with F(ab′)2 anti-CD4 and intact anti-CD4 were sacrificed for immunohistochemical analysis of their kidneys. Untreated B W mice had large lymphocytic aggregates under the surface epithelium of the renal calyces. Most of these lymphocytes were CD4+ T cells, but CD8+ T cells and B cells were also present. In contrast, treatment with either intact anti-CD4 or F(ab′)2 anti-CD4 substantially reduced, and in many cases prevented, the development of renal infiltrates. Treatment with either form of anti-CD4 not only inhibited renal infiltration by CD4+ T cells, but also prevented the accumulation of CD8+ T cells and B cells. These observations suggest a role for the CD4+ T cell in the accumulation of lymphocytes in target organs. |
