  • The main target of this project is to develop computational models and perform a series of experimental validations to identify the role of nanoparticle's mechanical stiffness in the cell uptake. (uga.edu)
  • MBP-pulsed B cells induced a low frequency of IL-10-producing CD4+ T cells in 3 out of 6 donors, indicating an immunoregulatory role of B cells presenting MBP-derived peptides. (regionh.dk)
  • An ethyl acetate extract of orange juice did not affect the initial uptake rate of [ 3 H]vinblastine but significantly increased the steady-state uptake, as did cyclosporin A (20 μM), an inhibitor of P-gp. (aspetjournals.org)
  • We also develop and use live-cell assays to show that {PCs} take up soluble macromolecules in a Dynamin-dependent manner and colloids by a Dynamin-independent pathway. (amrita.edu)
  • Amnionless helps transfer the cubilin-vitamin B12 complex into the intestinal cell. (medlineplus.gov)
  • When the extract was separated on a Cosmosil column, the eluate with 70% methanol showed the most potent ability to increase [ 3 H]vinblastine uptake. (aspetjournals.org)
  • B cells may play both pathogenic and protective roles in T-cell mediated autoimmune diseases such as multiple sclerosis (MS). These functions relate to the ability of B cells to bind and present antigens. (regionh.dk)
  • In plants, iron uptake from the soil is tightly regulated to ensure optimal growth and development. (nih.gov)
