OPTIMIZATION OF THE STRUCTURE OF PROTECTIVE FOREST PLANTATIONS AND THEIR SYSTEMS IN AGRICULTURAL LANDSCAPES OF UKRAINE

Optimization of the structure of protective forest plantations and their systems in agricultural landscapes of Ukraine

The intensification of agricultural production has significantly changed the structure of the land Fund, increased the ploughness and the proportion of arable land, causing intense processes of wind and water erosion.In such conditions, the role of protective forest plantations (PFP) of different purposes as the main stabilizing factor in agrofores

PD-L1: expression regulation

Programmed death-ligand Diaper Rash 1 (PD-L1), expressed on the surface of tumor cells, can bind to programmed cell death-1 (PD-1) on T cells.The interaction of PD-1 and PD-L1 can inhibit T-cell responses by decreasing T-cell activity and accelerating their apoptosis.Various cancers express high levels of PD-L1 and exploit PD-L1/PD-1 signaling to e
