Figure 2From: Lymphotoxin-beta receptor blockade reduces CXCL13 in lacrimal glands and improves corneal integrity in the NOD model of Sjögren's syndrome FACS analysis of leukocytes in lacrimal glands, spleen and blood. FACS analysis was performed on leukocytes from lacrimal-glands, spleen and in peripheral blood taken from NOD mice after treatment from 10 to 20 weeks with either MOPC-21 control protein (n = 7 mice) or LTBR-Ig (n = 8 mice), as indicated. Gating for marginal zone B-cells or MZB (B220+/CD23-int/CD21-hi) is depicted for spleen cells (a) with the MZB region indicated (red circle, third dot-plot). Treatment with LTBR-Ig reduced MZB in spleen but not lacrimal glands (b), reduced the percent of B-cells approximately 4-fold, whereas the percentage of B-cells in peripheral blood increased (c), reduced the B-cell to T-cell ratio in lacrimal glands (d) and reduced the percentage of CD11c cells among non-T non-B-cells (e). Similar experiments (treatment 8 - 16 weeks) were performed at least four times. LTBR-Ig; lymphotoxin-beta receptor-mouse immunoglobulin (Fc) chimeric inhibitor; MZB, marginal zone B-cell; NOD, non-obese diabetic.Back to article page
