Poxviruses encode many if not all of the proteins required for viral genome replication in the cytoplasm of the host cell. In this context, we investigated the function of the vaccinia virus G5 protein because it belongs to the FEN1-like family of nucleases and is conserved in all poxviruses. A vaccinia virus G5 deletion mutant was severely impaired, as the yield of infectious virus was reduced...
The release of GDP from GTPases signals the initiation of a GTPase cycle, where the association of GTP triggers conformational changes promoting binding of downstream effector molecules. Studies have implicated the nucleotide-binding G5 loop to be involved in the GDP release mechanism. For example, biophysical studies on both the eukaryotic Gα proteins and the GTPase domain (NFeoB) of prokaryot...
Liver X receptor (LXR) agonists increase both total fecal sterol excretion and macrophage-specific reverse cholesterol transport (RCT) in vivo. In this study, we assessed the effects of ABCG5/G8 deficiency as well as those of LXR agonist-induction of RCT from macrophages to feces in vivo. A [(3)H]cholesterol-labeled macrophage cell line was injected intraperitoneally into ABCG5/G8-deficient (G5...
This study aimed to evaluate the quimiopreventive ability of phenylalanine. We used pregnant and non-pregnant female mice divided into the following groups: G1-PBS, (0.1 mL/kg b.w); G2, cyclophosphamide (35 mg/kg p.c.-i.p.); G3 and G4, phenylalanine (150 and 300 mg/kg b.w respectively-v.o.) and G5 and G6, association between the two doses of phenylalanine and cyclophosphamide, respectively. The...
Cationic polymers such as poly(amidoamine), PAMAM, dendrimers have been used to electrostatically complex siRNA molecules forming dendriplexes for enhancing the cytoplasmic delivery of the encapsulated cargo. However, excess PAMAM dendrimers is typically used to protect the loaded siRNA against enzymatic attack, which results in systemic toxicity that hinders the in vivo use of these particles....
SUMMARY Biofilms are complex microbial communities found at surfaces that are often associated with extracellular polysaccharides. Biofilm formation is a complex process that is being understood at the molecular level only recently. We have identified a novel domain that we call the G5 domain (named after its conserved glycine residues), which is found in a variety of enzymes such as Streptococ...
We have investigated poly(amidoamine) (PAMAM) dendrimer interactions with supported 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) lipid bilayers and KB and Rat2 cell membranes using atomic force microscopy (AFM), enzyme assays, flow cell cytometry, and fluorescence microscopy. Amine-terminated generation 7 (G7) PAMAM dendrimers (10-100 nM) were observed to form holes of 15-40 nm in diamete...
Successful pregnancy in humans has been associated with production of IL-4 by T cells at the feto-maternal interface. Soluble HLA-G5 produced by trophoblasts potentially controls the decidual T cell cytokine profile. We studied the effect of HLA-G5 on the cytokine profile of purified human macrophages and Ag-specific T cells in vitro. We demonstrated that HLA-G5 increased production of IL-12 by...
Curigliano and Criscitiello, et al. [7] have addressed the molecular pathways of HLA-G. There are seven isoforms, four membrane bound (HLA-G1 to HLA-G-4); and three secreted isoforms (s HLA-G; HLA-G5 to HLA-G7). HLA-G5 is the soluble counterpart of HLA-G1; and most information known concerns the HLA-G1 molecule and its soluble counterpart HLA-G5. HLA-G induces tolerance and tumor Immunosuppress...
Der Ausbau des neuen Mobilfunkstandards 5G steht in den Startlochern und hat mancherorts bereits begonnen. Zu fragen ist, ob der weitgehend ungeregelte dieser Technologie vor dem Hintergrund zahlreicher Untersuchungen, die auf ein gesundheitliches Gefahrdungspotenzial Technik hinweisen, uberhaupt zulassig ist.
