Monocytes/macrophages constitute important contributors of cancer-associated inflammation. Through their plasticity and capacity to become polarised by tumours towards less activatory and more immunosuppressive (M2) phenotypes, tumour-associated macrophages (TAM) are thought to support tumour progression. Orchestrated by T helper 2 (Th2)-biased stimuli, macrophage recruitment, activation and po...
Biologically active conformations of the IgG1 Fc homodimer are maintained by multiple hydrophobic interactions between the protein surface and the N-glycan. The Fc glycan modulates biological effector functions, including antibody-dependent cellular cytotoxicity (ADCC) which is mediated in part through the activatory Fc receptor, FcγRIIIA. Consistent with previous reports, we found that site-di...
Natural killer (NK) cells are critical for innate tumor immunity due to their specialized ability to recognize and kill neoplastically transformed cells. However, NK cells require a specific set of cytokine-mediated signals to achieve optimal effector function. Th1-associated cytokines promote effector functions that are inhibited by the prototypic Th2 cytokine IL4 and the TGFβ superfamily memb...
this study examined the effects of collaborative strategic reading and direct instruction in persuasion on iranian high school students persuasive writing and attitudes. students in three intact classes were assigned to one of three treatment conditions: collaborative strategic reading and direct instruction in persuasion or direct instruction in persuasion or a control group. treatment effects...
The effects of the photoreactive GTP analogue GTP-gamma-azidoanilide on rat liver plasma-membrane adenylate cyclase are described. U.v. irradiation in the presence of the analogue abolished activation by any effector or combination of effectors that function via the activatory G protein. Partial protection against this inhibition was given by F- and guanosine 5'-[gamma-thio]triphosphate. It is ...
