Importantly, midbrain dopaminergic progenitor cell bead grafts showed increased survival and only mild immunoreactivity in vivo compared with suspended midbrain dopaminergic progenitor cell grafts. (bvsalud.org)

These hormones function by binding to specific receptor sites on target cells, thereby initiating a cascade of cellular events leading to various physiological effects. (outlookindia.com)
Myelinating OLs originate from parenchymal precursors expressing the neuron-glia antigen 2 (NG2) chondroitin sulphate proteoglycan and the platelet derived growth factor receptor alpha (PDGFRα), commonly referred to as oligodendrocyte progenitor cells (OPCs) 4 . (nature.com)

It is found that alloreactive donor-derived T cells activated through their T cell receptor (TCR) are primarily the major contributors to the immunopathobiology of GvHD. (umass.edu)

An FRα binding peptide C7 (Met-His-Thr-Ala-Pro-Gly-Trp-Gly-Tyr-Arg-Leu-Ser, MHTAPGWGYRLS) was found to bind to FRα expressing cells. (lifetein.com)

This study explores the mechanism of GALA anchored to gel-phase lipid vesicles in both clustered (pH and non-pH responsive) and uniform presentations with the goal of optimizing GALA presentation for improving therapeutic efficacy of tumor vasculature targeted liposome compositions. (aiche.org)

However, it has been shown that these conjugates were predominantly taken up by an endosomal mechanism preventing a proper interaction with targets located in the cytosol. (mpg.de)

Current use is limited by a lack of cell specificity in CPP-mediated cargo delivery and insufficient understanding of the modes of their uptake. (wikipedia.org)

The present invention is relative to chimerical peptides, whose primary structure holds at least one segment which inhibits the activation of the NS3 protease of a virus from the Flaviviridae family, they also contain a cell penetrating segment and they are capable of inhibiting or attenuate the viral infection.
