          Abstract

          Macrophages are key players in the development of the majority of renal diseases and are therefore ideal cellular vectors for site specifically targeting gene therapy to inflamed glomeruli. Macrophages can be genetically modified using viral vectors ex vivo then re-introduced into the body where they can home to the diseased site. This review summarises current experience in efficiently targeting modified macrophages to the inflamed glomerulus focussing on the factors controlling macrophage localisation, macrophage gene transfer methods, in vivo gene delivery and results of recent investigations using modified macrophage gene therapy for glomerular disease.

          Bone-marrow-derived macrophages genetically modified to produce IL-10 reduce injury in experimental glomerulonephritis.

          Macrophages are intimately involved in the development of immune-mediated inflammation, including glomerulonephritis. We have transduced primary cultures of macrophages to express IL-10 and tested the ability of these cells to control rat nephrotoxic nephritis (NTN), a model of human glomerulonephritis. Ad-IL-10-transduced bone-marrow-derived macrophages (BMDM) produced large amounts of IL-10 in culture, and their TNF-alpha production was decreased in response to interferon-gamma and LPS. Transduced macrophages were injected into the renal artery of rats, 6 h after the induction of NTN, where they localized efficiently to inflamed rat glomeruli. Delivery of IL-10-expressing macrophages to nephritic rats produced a marked reduction in albuminuria compared with unmodified NTN or injection of Ad-null-transduced BMDM. IL-10 treatment decreased the number of glomerular ED1- and ED3-positive cells, MHC class II expression, and the number of fibrinoid lesions. Interestingly, anti-inflammatory changes in the Ad-IL-10-injected kidney were mirrored by changes in the contralateral kidney. These results highlight that Ad-IL-10-transduced macrophages infiltrate inflamed glomeruli and reduce the severity of glomerular inflammation, emphasizing the value of local delivery of genetically modified macrophages in the manipulation of inflammatory disease.
