margination

 [mar″jĭ-na´shun]
accumulation and adhesion of leukocytes to the epithelial cells of blood vessel walls at the site of injury in the early stages of inflammation.

mar·gin·a·tion

(mar'ji-nā'shŭn),
A phenomenon that occurs during the relatively early phases of inflammation; as a result of dilation of capillaries and slowing of the bloodstream, leukocytes tend to occupy the periphery of the cross-sectional lumen and adhere to the endothelial cells that line the vessels.

The importance of certain stressors has been underscored: communication problems, social and cultural differences, economic problems, unemployment or poorly paid jobs, social margination, perception of discrimination, and, especially, the loss of social and family support (Hovey, 1999; Vargas-Willis & Cervantes, 1987).
