MMP-10 Regulates Collagenolytic Activity of Alternatively Activated Resident Macrophages
Matrix metalloproteinase-10 (MMP-10) is expressed by macrophages and epithelium in response to injury, but its functions in wound repair are unknown. We observed increased collagen deposition and skin stiffness in Mmp10(-/-) wounds, with no difference in collagen expression or reepithelialization. Increased collagen deposition in Mmp10(-/-) wounds was accompanied by less collagenolytic activity...
متن کاملAlternatively activated macrophages in infection and autoimmunity.
Macrophages are innate immune cells that play an important role in activation of the immune response and wound healing. Pathogens that require T helper-type 2 (Th2) responses for effective clearance, such as parasitic worms, are strong inducers of alternatively activated or M2 macrophages. However, infections such as bacteria and viruses that require Th1-type responses may induce M2 as a strate...
متن کاملLy6Chigh Monocytes Become Alternatively Activated Macrophages in Schistosome Granulomas with Help from CD4+ Cells
Alternatively activated macrophages (AAM) that accumulate during chronic T helper 2 inflammatory conditions may arise through proliferation of resident macrophages or recruitment of monocyte-derived cells. Liver granulomas that form around eggs of the helminth parasite Schistosoma mansoni require AAM to limit tissue damage. Here, we characterized monocyte and macrophage dynamics in the livers o...
متن کامل[Alternatively activated macrophages in helminth infections].
Macrophages not only initiate and modulate immune responses, but also are the final effector cells. Recent studies suggested that macrophages conventionally associated with IFN-gamma dominant Th1-type responses and also playing an essential role in the Th2-type inflammatory response, exhibit a quite different activation from the classically activated macrophages (CAM Phi) stimulated during Th1-...
متن کاملAlternatively activated macrophages derived from monocytes and tissue macrophages are phenotypically and functionally distinct.
Macrophages adopt an alternatively activated phenotype (AAMs) when activated by the interleukin-4receptor(R)α. AAMs can be derived either from proliferation of tissue resident macrophages or recruited inflammatory monocytes, but it is not known whether these different sources generate AAMs that are phenotypically and functionally distinct. By transcriptional profiling analysis, we show here tha...
