Description
We report a novel technique to reprogram human fibroblasts into endothelial and smooth muscle cells using partial iPSC reprogramming and chemically defined media. Using appropriate media conditions for differentiation of human pluripotent cells to CD34+ vascular progenitor cells, we show that temporary expression of pluripotent transcription factors and treatment with chemically-defined media, will induce differentiation of human fibroblasts to CD34+ vascular progenitor cells. Sorted CD34+ cells can then be directed to differentiate into vascular endothelial cells expressing a variety of smooth muscle markers.

Description
The intestinal immune system must elicit robust immunity against harmful pathogens but restrain immune responses directed against commensal microbes and dietary antigens. The mechanisms that maintain this dichotomy are poorly understood. Here we describe a population of CD11b+F4/80+CD11c macrophages in the lamina propria (LP) that express several anti-inflammatory molecules including interleukin 10 (IL-10), but little or no pro-inflammatory cytokines, even upon stimulation with Toll-like receptor (TLR) ligands. These macrophages induced, in a manner dependent on IL-10, retinoic acid and exogenous transforming growth factor-, differentiation of FoxP3+ regulatory T cells. In contrast, LP CD11b+ dendritic cells elicited IL-17 production. This IL-17 production was suppressed by LP macrophages, indicating that a dynamic interplay between these subsets may influence the balance between immune activation and tolerance.

Description
Infection with acute and chronic strains of LCMV (Armstrong (ARM) and Clone 13 (C13), respectively) leads to massive proliferation of monocytic cells contemporaneously with peak of the anti-viral CD8+ T cell response. These cells return to nave levels following ARM infection. However, during C13 infection these cells are sustained at high levels and gain a T cell suppressive function at day 14 post infection. The mechanisms by which these cells are induced to proliferate and impair T cell function during chronic LCMV infection are largely unknown. To address this, we analyzed gene expression profiles using microarray analysis of purified splenic monocytic cells (CD11b+ Ly6Chi Gr-1low) from nave mice, or day 14 LCMV ARM or LCMV C13 infected mice.

Description
Robust type I interferon (IFN-alpha/beta) production in plasmacytoid dendritic cells (pDCs) is critical for anti-viral immunity. Here we demonstrated a role for the mammalian target of rapamycin (mTOR) pathway in regulating interferon production by pDCs. Inhibition of mTOR or the downstream mediators of mTOR p70S6K1,2 kinases during pDC activation via Toll-like receptor 9 (TLR9) blocked the interaction of TLR9 with the adaptor MyD88 and the subsequent activation of interferon response factor 7 (IRF7), resulting in impaired IFN-alpha production. Microarray analysis confirmed that inhibition of mTOR by the immunosuppressive drug rapamycin suppressed anti-viral and anti-inflammatory gene expression. Consistent with this, targeting rapamycin-encapsulated microparticles to antigen-presenting cells in vivo resulted in a diminution of IFN-alpha production in response to CpG DNA or the yellow fever vaccine virus strain 17D. Thus, mTOR signaling plays a critical role in TLR-mediated IFN-alpha responses by pDCs.

Description
Dendritic cells play a vital role in initiating robust immunity against pathogens as well as maintaining immunological tolerance to self antigens, food antigens and intestinal commensals. However, the intracellular signaling networks that program DCs to become tolerogenic are largely unknown. To address this, we analyzed gene expression profiles using microarray analysis of purified intestinal lamina propria DCs (CD11c+ CD11b+ DCs and CD11c+ CD11b- DCs) and compared it to splenic DCs (CD11c+ DC), from mice.
