To elucidate the role of cell adhesion molecules in the pathogenesis of insulin-dependent diabetes mellitus and to determine the predominant lymphocytic homing pathway(s) involved in the selective lymphocytic infiltration of pancreatic islets (insulitis), nonobese diabetic mice were treated with monoclonal antibodies specific for the L-selectin and integrin alpha 4 lymphocyte adhesion molecules.

|
This tissue-specific inhibition of inflammation may be attributed to differences between the pancreas and salivary gland in their expression of endothelial ligands for L-selectin (peripheral vascular addressin) and for integrin alpha 4 (mucosal addressin cell adhesion molecule 1 and vascular cell adhesion molecule 1).
|

|
Mucosal addressin cell adhesion molecule 1 is highly expressed by vessels within the inflamed islets but was not detected in the salivary glands.

|
Therapeutic treatment with anti-L-selectin after the onset of insulitis from 10 to 14 weeks of age delayed the onset but failed to prevent spontaneous insulin-dependent diabetes mellitus, whereas anti-integrin alpha 4 treatment resulted in a significant and long-lasting suppression of the disease.

The alpha 4 beta 1-integrin (CD49d, CD29) constitutively expressed on leukocytes regulates cell migration to inflammatory sites, cell activation, and development through its interactions with two alternate ligands, vascular cell adhesion molecule-1 (VCAM-1; CD106) expressed on cytokine-activated endothelium, dendritic and stromal cells, and the extracellular matrix protein fibronectin.

Another alpha 4-integrin receptor, alpha 4 beta 7, expressed on leukocytes also binds VCAM-1 and fibronectin (FN), and controls homing to mucosal tissues through its interactions with mucosal vascular addressin MAdCAM-1.

This protection is associated with a marked decrease in the severity and incidence of insulitis and in the expression of the adhesion molecules MAdCAM-1 and ICAM-1 on the venules of pancreatic islets.

These data suggest a central role for TNF-alpha in the mediation of insulitis and of the subsequent destruction of insulin-secreting beta-cells observed in NOD mice.

Both in vitro and in vivo studies in NOD mice strongly suggest that the mucosal (alpha 4 beta 7/MAdCAM-1) adhesion system and alpha 4-integrin/VCAM-1 appear to be prominent pathways for insulitis development.

To determine whether lymphocyte homing to lymphoid organs is involved in the pathogenesis of diabetes in nonobese diabetic (NOD) mice, we blocked the function of the mucosal addressin cell adhesion molecule-1 (MAdCAM-1), which is a vascular addressin-mediating lymphocyte homing into mucosal lymphoid tissues, in these mice.

Although both subsets infiltrated the pancreas and elicited multiple adhesion receptors (peripheral lymph node addressin, mucosal addressin cell adhesion molecule-1, LFA-1, ICAM-1, and VCAM-1) on vascular endothelium, entry/accumulation of Th1 cells was more rapid than that of Th2 cells, and only Th1 cells induced diabetes.
|
23 |
10072490
|
In vitro, Th1 cells were also distinguished from Th2 cells by the capacity to synthesize several chemokines that included lymphotactin, monocyte chemoattractant protein-1 (MCP-1), and macrophage inflammatory protein-1alpha, whereas both subsets produced macrophage inflammatory protein-1beta.
|

|
Some of these chemokines as well as RANTES, MCP-3, MCP-5, and cytokine-response gene-2 (CRG-2)/IFN-inducible protein-10 (IP-10) were associated with Th1, but not Th2, pancreatic infiltrates.

Interactions of the integrins alpha(4)beta(7) with its cognate ligand mucosal addressin cell adhesion molecule-1 (MAdCAM-1) play a crucial role in the development of mucosa-associated lymphoid organs, in the generation of mucosal immune responses, and in diverse pathological processes such as chronic inflammatory bowel disease and type I diabetes.

Here, we completely blocked adoptive transfer of diabetes and reduced spontaneous disease incidence from 71% to 17% by simultaneously administering a combination of antibodies directed against alpha4, beta2, and beta7 integrins and their ligands VCAM-1, MAdCAM-1, and ICAM-1 for 52 and 28 days, respectively.

The reduced insulitis may be due to reduced expression of adhesion molecules since decreased numbers of islet-associated blood vessels expressing CD106 and MAdCAM-1 were detected following Linomide treatment.

|
Furthermore, short term Linomide treatment (3 or 7 days), which did not alter the number of infiltrating cells, was found to inhibit the production of TNF-alpha which is known to induce the expression of CD106 and MAdCAM-1.
