Diabetes is one of the major chronic diseases diagnosed worldwide with a common
complication of diabetic nephropathy (DN). There are multiple possible mechanisms
associated with DN. Aldose reductase (AR) and Toll-like receptor 4 (TLR4) may be
involved in the occurrence and development of DN. Here, we describe the
distribution of AR and TLR4 in cells and renal tissues of diabetic rats through a
quantum dot (QD)-based immunofluorescence technique and conventional
immunohistochemistry. As a new type of nanosized fluorophore, QDs have been
recognized in imaging applications and have broad prospects in biomedical
research. The results of the reported study demonstrate that both the AR and the
TLR4 proteins were upregulated in the renal tissues of diabetic rats. Further, to
explore the relationship between AR and TLR4 in the pathogenesis of DN, a
dual-color immunofluorescent labeling technique based on QDs was applied, where
the expressions of AR and TLR4 in the renal tissues of diabetic rats were
simultaneously observed - for the first time, as far as we are aware. The
optimized QD-based immunofluorescence technique has not only shown a satisfying
sensitivity and specificity for the detection of biomarkers in cells and tissues,
but also is a valuable supplement of immunohistochemistry. The QD-based
multiplexed imaging technology provides a new insight into the mechanistic study
of the correlation among biological factors as well as having potential
applications in the diagnosis and treatment of diseases.
