    Area of Science:

    • Ophthalmology
    • Diabetology
    • Biochemistry

    Background:

    • Diabetic retinopathy is characterized by the loss of retinal mural cells (pericytes).
    • The enzyme aldose reductase is implicated in diabetic complications.

    Purpose of the Study:

    • To investigate the presence and localization of aldose reductase in retinal mural cells.

    Main Methods:

    • Immunohistochemical analysis using antibodies against human placental aldose reductase.
    • Examination of trypsin-digested human retinal vessels.

    Main Results:

    • Aldose reductase was detected in the cytoplasm of retinal mural cells.
    • The enzyme's presence was confirmed in human retinal vessels.

    Conclusions:

    • Aldose reductase is present in retinal mural cells, supporting its potential role in early diabetic retinopathy pathogenesis.
