Megjegyzések:	The major reservoir of human multipotent mesenchymal stem/stromal cells (MSC) is the bone marrow (BM) with the capability to control hematopoietic stem cell (HSC) development. The regenerative potential of MSC is associated with enhanced endogenous repair and healing mechanisms that modulate inflammatory responses. Our previous results revealed that MSC-like (MSCl) cells derived from pluripotent human embryonic stem cells resemble BM-derived MSC in morphology, phenotype and differentiating potential. Here we investigated the effects of MSCl cells on the phenotype and functions of dendritic cells (DC). To assess how anti-viral immune responses could be regulated by intracellular pattern recognition receptors (PRR) of DC in the presence of MSCl cells we activated DC with the specific ligands of retinoic acid-inducible gene I (RIG-I) helicases and found that activated DC co-cultured with MSCl cells exhibited reduced expression of CD1a and CD83 cell surface molecules serving as phenotypic indicators of DC differentiation and activation, respectively. However, RIG-I-mediated stimulation of DC via specific ligands in the presence of MSCl cells resulted in significantly higher expression of the co-stimulatory molecules CD80 and CD86 than in the presence of BM-MSC. In line with these results the concentration of IL-6, IL-10 and CXCL8 was increased in the supernatant of the DC-MSCl co-cultures, while the secretion of TNF-?, CXCL10, IL-12 and IFN? was reduced. Furthermore, the concerted action of mechanisms involved in the regulation of DC migration resulted in the blockade of cell migration indicating altered DC functionality mediated by MSCl cell-derived signals and mechanisms resulting in a suppressive microenvironment.

Megjegyzések:	Every cell biological textbook teaches us that the main role of the plasma membrane is to separate cells from their neighborhood to allow for a controlled composition of the intracellular space. The mostly hydrophobic nature of the cell membrane presents an impenetrable barrier for most hydrophilic molecules larger than 1 kDa. On the other hand, cell-penetrating peptides (CPPs) are capable of traversing this barrier without compromising membrane integrity, and they can do so on their own or coupled to cargos. Coupling biologically and medically relevant cargos to CPPs holds great promise of delivering membrane-impermeable drugs into cells. If the cargo is able to interact with certain cell types, uptake of the CPP?drug complex can be tailored to be cell-typespecific.Besides outlining the major membrane penetration pathways of CPPs, this review is aimed at deciphering how properties of the membrane influence the uptake mechanisms of CPPs. By summarizing an extensive body of experimental evidence, we argue that a more ordered, less flexible membrane structure, often present in the very diseases planned to be treated with CPPs, decreases their cellular uptake. These correlations are not only relevant for understanding the cellular biology of CPPs, but also for rationally improving their value in translational or clinical applications.
