Abstract:
The architecture of lymphoid microenvironments depends upon complex interactions between several stromal cell types. We describe in this report the cloning of a cDNA which encodes a novel membrane molecule containing two external Ig-like domains. It is expressed at the junction between endothelial cells including HEV. It is also expressed by platelets and MHC class II+ antigen presenting cells in thymic medulla and T-cell areas in peripheral lymphoid organs. These cells which lack in RelB-deficient mice include tissue-derived dendritic, epithelial cells and macrophages. Thus, this molecule might contribute to the organization of cell junctions in different microenvironments.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Immunoglobulin-like Cell Adhesion Molecules
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...
Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...
Antigen Presenting Cells
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...
