(B) Association (open bars) and phagocytosis (closed bars) indices of J774 macrophages challenged with either C3bi- (top) or IgG- (bottom) RBCs. Indices were related to the values obtained from the negative controls (phagocytic indices of 110.5 5.7 and 131.5 2.1 for C3bi- and IgG-RBCs, r

Cell-based assays have and will allow the examination of system-level behavior of the JNK cascade and have been instrumental in revealing the all-or-none behavior of stress-activated JNK signaling (468). Clearly, a more thorough consideration of the time course of JNK activation will also be critical in this context (469). Lastly, greater efforts must be directed toward understanding the complexit
Considerations imply a need for `topology-sensitive' chaperones to protect disassembled SNAREs from off-pathway assembly reactions, to promote the geometrically complex assembly of trans-SNARE complexes, and to protect partly or fully assembled trans-SNARE complexes from the disassembly mediated by NSF until fusion has occurred, all while allowing cis-SNARE complexes (and those off-pathway interme
Bisexual men with AIDS instead of AIDS patients with hemophilad or intravenous drug users further support the existence of an infectious cofactor (Beral et al., 1990). According to the epidemiological data, several groups set out to identify a "KS agent" in the early 1990s. In 1994, Chang and Moore's group successfully identified the infectious cause of KS as a new herpesvirus called Kaposi's sarc
Blasts, refractory cytopenia with multilineage dysplasia, refractory cytopenia with multilineage dysplasia and ringed sideroblasts, RA with excess blasts (Type 1 and 2), 5q?syndrome, or unclassified. We specifically excluded from our analyses all patients with AA who also had a clinical diagnosis of PNH. The selection of patients for inclusion in the study was based on medical chart review and at
Method for the detection of protein rug interactions [70]. Although it is not based upon HDX, it is compatible with standard proteomic chromatography and it does provide for the identification of on- and offtarget drug interactions, and as such is expected to be of interest to the readers of this article. A thorough comparison of the SUPREX, PLIMSTEX and SPROX methods are given in a recent review
Y Data Acquisition--Samples were analyzed on an Ultimate 3000 nano HPLC (Dionex, Camberley, UK) system run in direct injection mode coupled to either a LTQ XL Orbitrap mass spectrometer, or a Q Exactive mass spectrometer (Thermo Electron, Hemel Hempstead, UK). Samples were resolved on a 15 cm by 75 m inner diameter picotip analytical column (New Objective, Woburn, MA), which was packed in-house wi
Tion, the AlphaScreen cAMP assay kit (PerkinElmer Life Sciences) was used according to the manufacturer's protocol. The accumulated cAMP was measured in 384well white OptiPlate microplates (PerkinElmer Life Sciences) with the Fusion AlphaScreen multilabel reader (PerkinElmer Life Sciences). To estimate cell surface expression of receptors carrying an N-terminal HA tag, we used an indirect cellular
Xis of the tissue. Limitations of This Study--Cartilage was harvested from 2?-week-old calves, and immature cartilage was more biologically active and was still forming matrix. Thus, although this model system may not completely capture the behavior of normal adult cartilage, it is useful to note that chondrocytes in adult osteoarthritic cartilage also have higher metabolic and biosynthetic activi
