Because immune mechanisms are implicated in atherogenesis, we investigated the T-lymphocyte subset and factors related to its activation after acute arterial ligation (22 ligated and 13 non-ligated specimens). Ligated arteries produced heat-shock protein 65 (hsp65) and were infiltrated with activated T cells (mostly dendritic, CD3+, CD4-, CD8-, and gamma/delta T-cell-receptor bearing). The protein was found with dendritic T cells, with immunogold-labelled hsp65 beside the dendritic processes. Thus, the immune reaction after acute arterial injury may be associated with binding and recognition of in-situ hsp65 by dendritic gamma/delta T-cells.
