Abstract
The immunohistological localization of peroxisome proliferator-activated receptor a (PPARa) and PPAR g was examined in 28 pilosebaceous units in 10 paraffin-embedded normal human skin specimens. Rabbit polyclonal antibody against human PPARa and monoclonal antibody against human PPARg were used as specific primary antibodies. The nuclear and cytoplasmic expression of PPARa was detected in basal to differentiated sebocytes. In contrast, the expression of PPARg was confined to nuclei of suprabasal to early-differentiated sebocytes. The nuclear PPARg expression was present only occasionally in the basal sebocytes. These results suggest that PPARa and PPARg are integral parts of sebocyte differentiation in human sebaceous glands.
