TL;DR: It is demonstrated that low concentrations of Toll-like receptor (TLR) ligands in the bloodstream drive CCR2-dependent emigration of monocytes from bone marrow and that bone marrow MSCs and CAR cells respond to circulating microbial molecules and regulate bloodstream monocyte frequencies by secreting MCP1 in proximity to bone marrow vascular sinuses.

TL;DR: An underlying mechanism of action of ASCs is proposed while drawing important distinctions between the properties of isolated ASCs, SVF, and MFAT and an underlying mechanism of action of ASCs is proposed while drawing important distinctions between the properties of isolated ASCs, SVF, and MFAT.

TL;DR: It is demonstrated that systems-level analysis can reveal critical molecular targets to optimize desirable properties in MSCs, and that overexpression of CD14 in these cells can shift their state to be more responsive to future bacterial challenge.

TL;DR: It is demonstrated that mesenchymal stem cells (MSCs), identified using nestin expression, constitute an essential HSC niche component and are indicative of a unique niche in the bone marrow made of heterotypic stem-cell pairs.

TL;DR: It is shown that increased lipopolysaccharide is bioactive in vivo and correlates with measures of innate and adaptive immune activation, which establish a mechanism for chronic immune activation in the context of a compromised gastrointestinal mucosal surface and provide new directions for therapeutic interventions that modify the consequences of acute HIV infection.
Recognition of microorganisms and activation of the immune response.
TL;DR: The mammalian immune system has innate and adaptive components, which cooperate to protect the host against microbial infections, and recent progress brings us closer to an integrated view of the immune system and its function in host defence.
