In situ quantification of T-lymphocyte subsets and Langerhans cells in the inflammatory infiltrate of atopic eczema.
Tissue from the acute, non-infected eruption of sixteen atopic eczema subjects was subjected to an indirect immunoperoxidase technique using monoclonal antibodies recognizing T-lymphocyte subsets, Langerhans cells and natural killer cells. Over half the cells infiltrating the dermis were T lymphocytes, including a large majority of helper T cells and relatively few suppressor T cells. Langerhans cells were present in significant proportions in the dermis and probably reflected increased antigen presentation within the affected skin. There was no evidence of increased natural killer cell presence. This study suggests that type IV hypersensitivity may be implicated in the aetiology of atopic eczema.
