Glycogen synthase kinase 3 (GSK-3) controls T-cell motility and interactions with antigen presenting cells [post]

2019 unpublished
Objective: The threonine/serine kinase glycogen synthase kinase 3 (GSK-3) targets multiple substrates in T-cells, regulating the expression of Tbet and PD-1 on T-cells. However, it has been unclear whether GSK-3 can affect the motility of T-cells and their interactions with antigen presenting cells. Results: Here, we show that GSK-3 can regulate T-cell motility. Inhibition of GSK-3, by small molecule SB415286, reduced T-cell motility in terms of distance and displacement. Although SB415286

These data indicate show that the inhibition of GSK-3 can influence the motility of T-cells and interactions with other cells without affecting the dwell times of cells that make productive contacts.
