Splenocytes from CIA mice were stained with anti-CD3, anti-CD4, anti-CD8, anti-CD44 and anti-CD62L antibodies, and the surface markers for activation in CD4+ and CD8+ T cells were analyzed using an LSR II flow cytometer (BD).
Platelet activation also leads to release of cytokines, thereby providing both the chemical signal and appropriate surface for leukocyte activation and adhesion [ 35, 36].
The potential-energy surface for the activation of ethylsilane by "naked" Co+ ions is investigated by using density functional theory at the B3LYP level of theory and a valence double zeta basis.
Many growth factors and cytokines require proteolytic release from the cell surface for their activation [11].
The SID module developed by Wysocki and co-workers incorporates a pass-through design such that ions can be transmitted or selectively introduced to a collision surface for ion activation, while retaining the conventional operation of the instrumentation in which it is integrated, including CID.
However, Notch1 and Notch2 receptors engineered to resist S1 cleavage exhibit unexpected differences in surface delivery and signaling competence: S1-resistant Notch1 receptors exhibit decreased, but detectable, surface expression and ligand-mediated receptor activation, whereas S1-resistant Notch2 receptors are fully competent for cell surface delivery and for activation by ligands.
In contrast to Notch1 receptors, S1-resistant Notch2 receptors are fully competent for cell surface delivery and for activation by ligands.
However, γ-secretase dependent, ligand-mediated activation of N1-GAL4-LO receptors was still readily detectable, indicating that some of the receptors reaching the cell surface are competent for activation (Supplemental Figure S6).
CRT expressed on cancer cell surface is important for activation of immune responses.
Scanning electron microscopy and mechanical studies revealed that the use of plasma for surface activation allows for the non-destructive immobilization of bioactive compounds like hyaluronic acid.
