Title: Increased responsiveness to macrophage-activating factor (MAF) after alteration of macrophage membranes. Author: Piessens WF, Remold HG, David JR. Journal: J Immunol; 1977 Jun; 118(6):2078-82. PubMed ID: 325137. Abstract: Guinea pig macrophages pretreated with the esterase inhibitor, antithrombin III (AT III) show increased responsiveness to macrophage-activating factor (MAF) as demonstrated by their enhanced cytotoxicity for tumor cells. Other proteins that are not esterase inhibitors did not enhance the effect of MAF on the macrophage. Enhancement of MAF activity was also obtained when macrophages were preincubated with the cell surface reactant, diazotized sulfanilic acid (DSA). These studies indicate that the effect of MAF can be enhanced by chemical modifications of the macrophage membrane. They also provide further evidence to support the hypothesis that an esterase on the macrophage membrane modulates this cell's responsiveness to lymphocyte mediators.[Abstract] [Full Text] [Related] [New Search]
