Characterization of the IL-15 niche in primary and secondary lymphoid organs in vivo.

Cui G1, Hara T, Simmons S, Wagatsuma K, Abe A, Miyachi H, Kitano S, Ishii M, Tani-Ichi S, Ikuta K.Author information 1Laboratory of Biological Protection, Department of Biological Responses, Institute for Virus Research, Kyoto University, Kyoto 606-8507, Japan.AbstractIL-15 is a cytokine critical for development, maintenance, and response of T cells, natural killer (NK) cells, NK T cells, and dendritic cells. However, the identity and distribution of IL-15-expressing cells in lymphoid organs are not well understood. To address these questions, we established and analyzed IL-15-CFP knock-in mice. We found that IL-15 was highly expressed in thymic medulla, and medullary thymic epithelial cells with high MHC class II expression were the major source of IL-15. In bone marrow, IL-15 was detected primarily in VCAM-1(+)PDGFRβ(+)CD31(-)Sca-1(-) stromal cells, which corresponded to previously described CXCL12-abundant reticular cells. In lymph nodes, IL-15-expressing cells were mainly distributed in the T-cell zone and medulla. IL-15 was expressed in some fibroblastic reticular cells and gp38(-)CD31(-) double-negative stromal cells in the T-cell zone. Blood endothelial cells, including all high endothelial venules, also expressed high IL-15 levels in lymph nodes, whereas lymphatic endothelial cells (LECs) lacked IL-15 expression. In spleen, IL-15 was expressed in VCAM-1(+) stromal cells, where its expression increased as mice aged. Finally, IL-15 expression in blood and LECs of peripheral lymphoid organs significantly increased in LPS-induced inflammation. Overall, we have identified and characterized several IL-15-expressing cells in primary and secondary lymphoid organs, providing a unique perspective of IL-15 niche in immune microenvironment. This study also suggests that some stromal cells express IL-7 and IL-15 differentially and suggests a way to functionally classify different stromal cell subsets.

The pathogenesis of severe Fever with thrombocytopenia syndrome virus infection in alpha/beta interferon knockout mice: insights into the pathologic mechanisms of a new viral hemorrhagic Fever.

Liu Y1, Wu B, Paessler S, Walker DH, Tesh RB, Yu XJ.Author information 1Department of Pathology, University of Texas Medical Branch, Galveston, Texas, USA.AbstractSevere fever with thrombocytopenia syndrome virus (SFTSV) is a newly discovered Phlebovirus causing an emerging hemorrhagic fever in East Asia, with reported case fatality rates up to 30%. Despite the high case fatality rate and large number of persons at risk of infection, the pathobiology of the disease is unknown, and no effective animal model has been available for investigating its pathogenesis. We have studied mice and hamsters as potential small-animal models of SFTSV infection following subcutaneous, intraperitoneal, or intracerebral inoculation. Animal tissues were processed for viral load determination, histopathology, immunohistochemistry, and confocal microscopic studies. We found that immunocompetent adult mice and hamsters did not become ill after SFTSV infection. However, alpha/beta interferon receptor knockout (IFNAR(-/-)) mice were highly susceptible to SFTSV infection, and all mice died within 3 to 4 days after subcutaneous inoculation of 10(6) focus-forming units of SFTSV. Histologic examination of tissues of IFNAR(-/-) mice infected with SFTSV showed no detectable lesions. In contrast, by immunohistochemistry virus antigen was found in liver, intestine, kidney, spleen, lymphoid tissue, and brain, but not in the lungs. Mesenteric lymph nodes and spleen were the most heavily infected tissues. Quantitative reverse transcription-PCR (RT-PCR) confirmed the presence of virus in these tissues. Confocal microscopy showed that SFTSV colocalized with reticular cells but did not colocalize with dendritic cells, monocytes/macrophages, neutrophils, or endothelium. Our results indicate that SFTSV multiplied in all organs except for lungs and that mesenteric lymph nodes and spleen were the most heavily infected tissues. The major target cells of SFTSV appear to be reticular cells in lymphoid tissues of intestine and spleen.
