Primary cells enter replicative senescence after a limited number of cell divisions. This process needs to be considered in cell culture experiments, and it is particularly important for regenerative medicine. Replicative senescence is associated with reproducible changes in DNA methylation
T cell activation is initiated by signaling molecules downstream of the T cell receptor (TCR) that are organized by adaptor proteins. CIN85 (Cbl-interacting protein of 85 kDa) is one such adaptor protein. Here, we showed that CIN85 limited T cell
Cell migration is a stepwise process that coordinates multiple molecular machineries. Using in vitro angiogenesis screens with short interfering RNA and chemical inhibitors, we define here a MAP4K4-moesin-talin-β1-integrin molecular pathway that promotes efficient plasma membrane retraction during endothelial cell migration.

The imidazolium cation was chosen as protein selective affinity group and a kind of ionic liquid magnetic microspheres was developed by immobilizing imidazolium cations onto the surface of silica-coated magnetic microspheres to form imidazolium ionic liquid modified magnetic microspheres (Fe3O4@SiO2@IL).

Pneumocystis organisms are opportunistic fungal pathogens that cause significant pneumonia in immune-compromised hosts. Recent evidence has suggested that Pneumocystis carinii exists as separate mating types, and expresses and regulates proteins that govern meiosis and progression of the life cycle. This
Protein purification techniques, reagents, and protocols for purifying recombinant proteins using methods including, ion-exchange, size-exclusion, and protein affinity chromatography.
