A crosstalk triggered by hypoxia and maintained by MCP-1/miR-98/IL-6/p38 regulatory loop between human aortic smooth muscle cells and macrophages leads to aortic smooth muscle cells apoptosis via Stat1 activation.

Abstract
Hypoxia and inflammation are central characteristics of the abdominal aortic aneurysm (AAA), but the mechanisms for their relationship and actual role remain far from full understood. Here, we showed MCP-1 (monocyte chemotactic protein-1) induced by hypoxia in primary human Aortic Smooth Muscle Cells (hASMCs) increased the chemotaxis of THP-1 macrophages and MCP-1 induced IL-6 expression in THP-1 cells via downregulating miR-98 which directly targets IL-6. In addition, IL-6 positively feedback regulated MCP-1 expression in hASMCs via p38 signal that is independent on hypoxia, and inhibition of p38 signal blocked the effect of IL-6 on MCP-1 expression regulation. Moreover, IL-6 exposure time-dependently induces phASMCs apoptosis via Stat1 activation. Collectively, our data provide compelling evidence on the association between hypoxia and inflammation triggered by hypoxia and then mediated by MCP-1/miR-98/IL-6/p38 regulatory loop, which leads to hASMCs apoptosis via Stat1 activation to contribute to AAA formation and progression.

Abstract
RATIONALE Depletion of medial smooth muscle cell (SMC) is a major pathological characteristic of abdominal aortic aneurysm (AAA), although the mechanism by which these cells are eliminated remains incompletely understood. We reasoned that necroptosis, a recently described form of necrosis mediated by receptor-interacting protein kinase 3 (RIP3), may contribute to AAA pathology through the induction of SMC death and the significant production of inflammatory cytokines. OBJECTIVE To test the hypothesis that RIP3-mediated necroptosis is actively involved in aneurysm pathogenesis. METHODS AND RESULTS RIP3 and RIP1 levels were found to be elevated in human AAAs, most noticeably in SMCs. Elevations of RIP3 and SMC necrosis were also observed in the elastase-induced mouse model of AAAs. Deletion of one or both copies of Rip3 prevented AAA formation. By transplanting Rip3(+/-) aortae to Rip3(+/+) mice, we demonstrated that reduced Rip3 expression in arterial wall was the primary cause of aneurysm resistance. In vitro, adenoviral overexpression of RIP3 was sufficient to trigger SMC necroptosis. Protein kinase C-delta contributed to tumor necrosis factor-α-induced SMC necroptosis by regulating Rip3 expression. Furthermore, Rip3 deficiency impaired tumor necrosis factor-α-induced inflammatory gene expression in aortic SMCs, which was at least in part because of attenuation of p65 Ser536 phosphorylation. In vivo, the lack of RIP3 diminished activation of p65 in SMCs, implicating a necrosis independent function of RIP3 in aneurysms. CONCLUSIONS Enhanced RIP3 signaling in aneurysmal tissues contributes to AAA progression by causing SMC necroptosis, as well as stimulating vascular inflammation, and therefore may serve as a novel therapeutic target for AAA treatment.

Abstract
Ocular immune privilege (IP) limits the immune surveillance of intraocular tumors as certain immunogenic tumor cell lines (P815, E.G7-OVA) that are rejected when transplanted in the skin grow progressively when placed in the anterior chamber of the eye. As splenectomy (SPLNX) is known to terminate ocular IP, we characterized the immune mechanisms responsible for rejection of intraocular tumors in SPLNX mice as a first step toward identifying how to restore tumoricidal activity within the eye. CD8(+) T cells, IFNγ, and FasL, but not perforin, or TNFα were required for the elimination of intraocular E.G7-OVA tumors that culminated in destruction of the eye (ocular phthisis). IFNγ and FasL did not target tumor cells directly as the majority of SPLNX IFNγR1(-/-) mice and Fas-defective lpr mice failed to eliminate intraocular E.G7-OVA tumors that expressed Fas and IFNγR1. Bone marrow chimeras revealed that IFNγR1 and Fas expression on immune cells was most critical for rejection, and SPLNX increased the frequency of activated macrophages (Mϕ) within intraocular tumors in an IFNγ- and Fas/FasL-dependent manner, suggesting an immune cell target of IFNγ and Fas. As depletion of Mϕs limited CD8 T cell-mediated rejection of intraocular tumors in SPLNX mice, our data support a model in which IFNγ- and Fas/FasL-dependent activation of intratumoral Mϕs by CD8(+) T cells promotes severe intraocular inflammation that indirectly eliminates intraocular tumors by inducing phthisis, and suggests that immunosuppressive mechanisms that maintain ocular IP interfere with the interaction between CD8(+) T cells and Mϕs to limit the immunosurveillance of intraocular tumors.

Murine abdominal aortic aneurysm model by orthotopic allograft transplantation of elastase-treated abdominal aorta. J Vasc Surg 2014; 62:1607-14.e2. [PMID: 24974783 DOI: 10.1016/j.jvs.2014.05.019] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2014] [Accepted: 05/06/2014] [Indexed: 12/15/2022]
Abstract
OBJECTIVE Murine models have proved instrumental in studying various aspects of abdominal aortic aneurysm (AAA), from identification of underlying pathophysiologic changes to the development of novel therapeutic strategies. In the current study, we describe a new model in which an elastase-treated donor aorta is transplanted to a recipient mouse and allowed to progress to aneurysm. We hypothesized that by transplanting an elastase-treated abdominal aorta of one genotype to a recipient mouse of a different genotype, one can differentiate pathophysiologic factors that are intrinsic to the aortic wall from those stemming from circulation and other organs. METHODS Elastase-treated aorta was transplanted to the infrarenal abdominal aorta of recipient mice by end-to-side microsurgical anastomosis. Heat-inactivated elastase-treated aorta was used as a control. Syngeneic transplants were performed with use of 12-week-old C57BL/6 littermates. Transplant grafts were harvested from recipient mice on day 7 or day 14 after surgery. The aneurysm outcome was measured by aortic expansion, elastin degradation, proinflammatory cytokine expression, and inflammatory cell infiltration and compared with that produced with the established, conventional elastase infusion model. RESULTS The surgical technique success rate was 75.6%, and the 14-day survival rate was 51.1%. By day 14 after surgery, all of the elastase-treated transplanted abdominal aortas had dilated and progressed to AAAs, defined as 100% or more increase in the maximal external diameter compared with that measured before elastase perfusion, whereas none of the transplanted aortas pretreated with inactive elastase became aneurysmal (percentage increase in maximum aortic diameter: 159.36% ± 23.27%, transplanted elastase, vs 41.46% ± 9.34%, transplanted inactive elastase). Aneurysm parameters, including elastin degradation and infiltration of macrophages and T lymphocytes, were found to be identical to those observed in the conventional elastase model. Quantitative polymerase chain reaction analysis revealed similarly increased levels of proinflammatory cytokines (relative changes of mRNA in the conventional elastase model vs transplant model: tumor necrosis factor α, 1.71 ± 0.27 vs 2.93 ± 0.86; monocyte chemoattractant protein 1, 2.36 ± 0.58 vs 2.87 ± 0.51; chemokine (C-C motif) ligand 5, 3.37 ± 0.92 vs 3.46 ± 0.83; and interferon γ, 3.09 ± 0.83 vs 5.30 ± 1.69). Using green fluorescent protein transgenic mice as donors or recipients, we demonstrated that a small quantity of mononuclear leukocytes in the transplant grafts bared the genotype of the donors. CONCLUSIONS Transplanted elastase-treated abdominal aorta could develop to aneurysm in recipient mice. This AAA transplant model can be used to examine how the microenvironment of a transplanted aneurysmal aorta may be altered by the contributions of the "global" environment of the recipient.
