Complement is important for elimination of invasive microbes from the host, an action achieved largely through interaction of complement-decorated pathogens with various complement receptors (CR) on phagocytes. Pneumococcal surface protein A (PspA) has been shown to interfere with complement deposition onto pneumococci, but to date the impact of PspA on CR-mediated host defense is unknown. To g...
In vitro evaluation of specific anti-Candida albicans sera antibodies based on synthetically prepared complement receptor 3-related protein (CR3-RP) mimicking the structure of native complement receptor 3 in a cohort of 72 patients with atopy and recurrent Candida vulvovaginitis (RVC) revealed effective humoral response against Candida CR3-RP. The most significant have been IgM and IgA isotype ...
The toxicity of engineered nanoparticles remains a concern. The knowledge of biohazards associated with particular nanoparticles is crucial to make this cutting-edge technology more beneficial and safe. Here, we evaluated the toxicity of Ga2O3 nanoparticles (NPs), which are frequently used to enhance the performance of metal catalysts in a variety of catalytic reactions. The potential inflammat...
The expression of C5a receptors (C5aR) on human leukocytes was evaluated by flow cytometry using fluorescein-labeled human C5a (C5a-F). Granulocytes and CD14+ mononuclear cells (MNL) but not CD3+, CD20+, CD16+, CD56+, or CD11b+ lymphocytes in peripheral blood and spleen bound C5a-F. C5a-F binding was saturable and inhibitable by anti-C5a monoclonal antibody (MoAb) C17/5 or unlabeled C5a. During...
Yeast inorganic pyrophosphatase was found to bind two Mn2+ per subunit in the absence of phosphate and three Mn2+ per subunit in the presence of phosphate. Kinetic studies of the pyrophosphatase-catalyzed hydrolysis of Cr(NH3)4PP and Cr(H2O)4PP were carried out with Mn2+ and with Mg2+ as activators. The results from these studies suggest that three divalent cations per pyrophosphatase active si...
The potassium, ammonium and thallium alums form continuous series of solid solutions. By means of xray diffraction Klug and Alexander [1] have shown that these solid solutions are ideal from the stand point of Vegard’s law [2], particularly solid solutions of ammonium and thallium alum [1]. Jain [3] has studied the electron spin resonance (ESR) of Cr3+ in single crystals of mixed alums of ammon...
We have designed and validated a novel generic platform for production of tetravalent IgG1-like chimeric bispecific Abs. The VH-CH1-hinge domains of mAb2 are fused through a peptidic linker to the N terminus of mAb1 H chain, and paired mutations at the CH1-CL interface mAb1 are introduced that force the correct pairing of the two different free L chains. Two different sets of these CH1-CL inter...
Chromium (Cr3+) doped iron pyrite (FeS2) thin films were deposited on ITO substrate by a facile electrochemical deposition process. The effect of chromium content structural, optical, electrical, morphological, and electrocatalytic behavior the examined. X - ray diffraction studies confirmed formation cubic crystal structure films. Atomic force microscopy results indicate that Cr3+ doping has s...
The leukocyte integrin complement receptor type 3 (CR3, Mac-1, CD11b/CD18) is the predominant beta(2) integrin receptor of polymorphonuclear leukocytes (PMNs). This cell surface receptor plays a central role in innate immunity against pathogens as well as being a major cellular effector of inflammation and tissue injury. Two small molecules, compounds 1 and 2, have been identified, that interac...
Complement Receptor 3 (CR3) and Toll-like Receptor 2 (TLR2) are pattern recognition receptors expressed on the surface of human macrophages. Although these receptors are essential components for recognition by the innate immune system, pathogen coordinated crosstalk between them can suppress the production of protective cytokines and promote infection. Recognition of the virulent Schu S4 strain...
