WebSep 13, 2024 · In this review, we discussed the NK cell phenotypes and its effector function and impact of the tumor microenvironment on effector and cytolytic function of NK cells. We also summarized various NK cell-based immunotherapeutic strategies used in the past and the possibilities to improve the function of NK cell for the better clinical outcome. WebApr 21, 2011 · Furthermore, CD11b + SP NK cells showed high cytolytic function. Such a variety of characteristics demonstrates that human NK cells in different developmental stages have special functions. On the basis of these results, we developed and functionally characterized a new model for the development of human NK cells. Materials and methods

WebA defect in cytolytic function may result in overstimulation of the immune system leading to the multi-organ failure seen in MAS. The pro-inflammatory cytokine environment, particularly IL-6, has been shown to decrease NK … Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. Water can enter the cell by diffusion through the cell membrane or through selective membrane channels called aquaporins, which greatly facilitate the flow of water. It occurs in a hypotonic environment, where water moves into the cell by osmosis and cause…
