Reduced deaf1 mRNA expression during STZ-induced diabetes mellitus inhibits foxp3+regulatory T-cells differentiations in rat’s pancreatic lymph nodes

Alex Kamyshny, Denis Putilin, Vita Kamyshna


We studied to determine the effect of the levels of Deaf1 mRNA expression on the nature of Foxp3+ Treg cells differentiation during experimental STZ-induced diabetes mellitus (EDM) in rats PLN. To determine the level of Deaf1 mRNA expression was performed RT-PCR in real-time by thermocycler CFX96â„¢ Real-Time PCR Detection Systems. The Foxp3+-immunopositive lymphocytes were determined using an indirect immunofluorescence technique with using a monoclonal rat antibody. We established that development of EDM was accompanied by decreased the expression levels of the transcriptional regulator Deaf1 4,2â€fold in rats PLN with 3-week EDM and 2,5â€fold in rats with 5-week EDM. Reduced Deaf1 mRNA expression during EDM associated with an decreased of total amount of Treg in the PLN, led to changes of distribution into individual classes of FoxP3+ lymphocytes and FoxP3 concentration in immunopositive cells.
