Immunoglobulins in hypertrophic scars and keloids.
Immunoglobulins A, G, and M were localized in normal skin, hypertrophic scars, keloids, and mature scars by the direct immunofluorescent antibody method. All three immunoglobulins appeared increased in the lesions above levels observed in normal skin. Extractions of the immunoglobulins from the same type of tissues also suggested an increase above levels from normal skin. The data suggest attritional leakage of several plasma proteins from the microvasculature in the lesions. No one immunoglobulin appears significantly increased in the lesions compared with others.
