Abstract

After a busy morning out in the garden, I thought I'd sit down and catch up on Gardening Australia. I had thought the purple-flowering plant, which is one of the best bee-attracting plants in my garden, to be justicia, and the pink-fowering plant to be jacobinia, or Brazilian plume flower. Fallen leaves are a source of spores for reinfection, so remove all leaf matter below the plant, too. [Extracted from the article]

5. Lead Discovery for Human Kynurenine 3-Monooxygenase by High-Throughput RapidFire Mass Spectrometry

Lowe, Denise M., Gee, Michelle, Haslam, Carl, Leavens, Bill, Christodoulou, Erica, Hissey, Paul, Hardwicke, Philip, Argyrou, Argyrides, Webster, Scott P., Mole, Damian J., Wilson, Kris, Binnie, Margaret, Yard, Beverley A., Dean, Tony, Liddle, John, Uings, Iain, and Hutchinson, Jonathan P.

Abstract

Kynurenine 3-monooxygenase (KMO) is a therapeutically important target on the eukaryotic tryptophan catabolic pathway, where it converts L-kynurenine (Kyn) to 3-hydroxykynurenine (3-HK). We have cloned and expressed the human form of this membrane protein as a full-length GST-fusion in a recombinant baculovirus expression system. An enriched membrane preparation was used for a directed screen of approximately 78,000 compounds using a RapidFire mass spectrometry (RF-MS) assay. The RapidFire platform provides an automated solid-phase extraction system that gives a throughput of approximately 7 s per well to the mass spectrometer, where direct measurement of both the substrate and product allowed substrate conversion to be determined. The RF-MS methodology is insensitive to assay interference, other than where compounds have the same nominal mass as Kyn or 3-HK and produce the same mass transition on fragmentation. These instances could be identified by comparison with the product-only data. The screen ran with excellent performance (average Z′ value 0.8) and provided several tractable hit series for further investigation.

Abstract

Peripheral blood mononuclear cells (PBMC) from a patient suffering from the hyper IgE syndrome were used to generate phytohaemagglutinin (PHA)-expanded T-cell clones (all CD4+, CD8-, CD23-). A selection of the clones was tested for their ability to help IgE secretion by culturing with normal B cells in the presence of solid-phase antibody to CD3. Supernatants were harvested on Day 7 and assayed by ELISA for IgE, IgG and IgM. Lymphokine secretion by the clones was assessed by culturing clones for 24 hr with solid-phase antibody to CD3 followed by assay of the supernatants for IL-2, IL-4 and interferon-gamma (IFN-γ) production. In addition, clones were analysed by flow cytometry for CDw29 and CD45R expression. Initial experiments with seven clones indicated that those clones that could help IgE secretion also stimulated optimal IgG and IgM responses. All clones appeared to secrete IL-2, IL-4 and IFN-γ, although the mounts of each varied. These results confirm recent findings that human T-cell clones do not fall into Tinf (Th1) and Th (Th2) type subsets as described in the muse. There was no clear correlation between the lymphokines secreted by the clones and their capacity to help IgE production. However, the helper function of the clones for all isotypes, including IgE, appeared to be related to the level of expression of the surface antigen CDw29. [ABSTRACT FROM AUTHOR]

7. Tissue Repair with a Therapeutic Transcription Factor

Author

Bryant, Mark, Drew, Geoffrey M., Houston, Parul, Hissey, Paul, Campbell, Callum J., and Braddock, Martin

Abstract

The healing of tissue involves a wide range of molecular, cellular, and physiological events that are coordinated in a temporally specific manner. The cellular transcription factor early growth response factor 1 (Egr1) is expressed minutes after acute injury and serves to stimulate the production of a class of growth factors whose role is to promote tissue repair. We have studied the effects of Egr-1 expression at the site of dermal wounding in rodents. We find that Egr-1 promotes angiogenesis in vitro and in vivo, increases collagen production, and accelerates wound closure. These results show that Egr-1 gene therapy accelerates the normal healing process and raises the potential use of this therapeutic transcription factor for any aspect of tissue repair.

8. Purification and characterization of recombinant human interleukin 4. Biological activities, receptor binding and the generation of monoclonal antibodies

Author

Solari, R, Quint, D, Obray, H, McNamee, A, Bolton, E, Hissey, P, Champion, B, Zanders, E, Chaplin, A, Coomber, B, Watson, M, Roberts, B, and Weir, M

Abstract

A synthetic gene coding for human interleukin 4 (IL-4) was cloned and expressed in Saccharomyces cerevisiae (baker's yeast) as a C-terminal fusion protein with the yeast prepro alpha-mating factor sequence, resulting in secretion of mature IL-4 into the culture medium (0.6-0.8 micrograms/ml). A protocol was developed for purification of this protein. Crude cell-free conditioned medium was passed over a concanavalin A-Sepharose affinity column; bound proteins were eluted and further purified by S-Sepharose Fast Flow cation exchange and C18 reverse-phase h.p.l.c. Highly purified IL-4 was obtained by this method (0.3-0.4 mg per litre of culture) with a recovery of 51%. Thermospray liquid chromatography-mass spectrometry showed the C-terminal N-glycosylation site to be largely unmodified, and also showed that the N-terminus of the purified recombinant IL-4 (rIL-4) was authentic. Thiol titration revealed no free cysteine residues, implying that there are three disulphide groups, the positions of which remain to be determined. We have characterized the biological activities of the purified rIL-4. This material is active in B-cell co-stimulator assays, T-cell proliferation assays and in the induction of cell-surface expression of CD23 (the low-affinity receptor for IgE) on tonsillar B-cells. Half-maximal biological activity of the rIL-4 was achieved at a concentration of 120 pM. We have radioiodinated rIL-4 without loss of biological activity and performed equilibrium binding studies on Raji cells, a human B-cell line. The 125I-rIL-4 bound specifically to a single class of binding studies on Raji cells, a human B-cell line. The 125I-rIL-4 bound specifically to a single class of binding site with high affinity (Kd = 100 pM) and revealed 1100 receptors per cell. Receptor-ligand cross-linking studies demonstrated a single cell-surface receptor with an apparent molecular mass of 124 kDa. Two monoclonal antibodies have been raised to the human rIL-4, one of which blocks both the biological activity of rIL-4 and binding to its receptor.

Abstract

The article discusses the requirements and maintenance of prints. The first basic requirement of film prints is a good negative, in first class physical condition and free from oil, dirt and abrasions. Processed prints must be kept in a damp-free conditions at proper temperature to protect it against shrinkage of the base and decrease in flexibility owing to loss of moisture content.

Abstract

Background: The ability to derive immunological reagents for basic and applied research in a timely fashion is a basic requirement of many research projects and is becoming increasingly important as the number of novel gene products of potential interest continues to evolve rapidly. DNA immunization provides a means of facilitating the production of antibody reagents by circumventing the need to derive either purified protein or define peptides before initiating an in vivo immunization protocol., Objectives: The DNA construct pPV, for plasmid vaccination, has been designed to facilitate the generation and characterization of antibody reagents against either random or defined molecular targets., Study Design: pPV incorporates mammalian regulatory and structural features that promote expression of a bifunctional messenger RNA (mRNA) from a single promoter within mammalian cells both in vitro and in vivo. The bifunctional mRNA encodes a control epitope (human IL5), and the 'test' epitope expressed as a tagged recombinant polypeptide in either a random 'shot-gun' mode or a predetermined fashion. In addition, to aid subsequent characterization of antibody responses elicited in vivo, a T7 promoter is included to enable in vitro expression of tagged recombinant polypeptides., Results: The utility and functionality of pPV for the in vitro expression of recombinant protein and the in vivo elicitation of antibody responses is illustrated using a defined 'test' epitope, human proIL1 beta., Conclusion: It is anticipated pPV will find particular utility in the future rapid generation and characterization of antibody reagents against the plethora of novel genes emerging from ongoing genomics activity in a directed or genome wide fashion.

Abstract

Antigenic sites on Pneumocystis carinii, the basis for organism enumeration by an enzyme-linked immunosorbent assay (ELISA) were adversely affected by incubation in detergents. However, stronger detergent concentrations were needed to eliminate high levels of non-specific background. Good P. carinii quantification was obtained with low non-specific background when the detergent was used only in the washing steps and not in cell suspension solutions. Formalin fixation of the cells resulted in good ELISA quantification of organism numbers with low non-specific background. No adverse effects were observed using a detergent on fixed cells. Although the system's range of accuracy needs to be expanded, a reduction in the number of organisms in response to the effects of pentamidine in vitro could be demonstrated by ELISA.

Abstract

Two mouse monoclonal antibodies (Mabs) against recombinant human interleukin-5(rhIL-5) have been produced, characterised and purified. Both are IgG1 antibodies and neutralised the activity of rhIL-5 in the B13 assay. Neither Mab cross-reacted with mouse IL-5. A two-site sandwich enzyme-linked immunosorbent assay (ELISA) was developed with different combinations of the mouse Mabs and also a rat anti-mouse IL-5 Mab, TRFK5, which also has activity against rhIL-5. The most sensitive assay, with a lower detection limit of 0.5 ng/ml IL-5, used TRFK5 as the capture antibody and the mouse anti-human IL-5 Mab as second antibody. The sensitivity of this assay was increased by an enhanced chemiluminescent reagent and resulted in a lower limit of detection around 40 pg/ml IL-5.

Abstract

The use of a monoclonal antibody (MAb) affinity column to purify epidermal growth factor/urogastrone from human urine in a single-step process is described. The MAb was raised against purified recombinant human urogastrone derived from the expression of a cloned synthetic urogastrone gene. The MAb was characterised and shown to cross-react fully with recombinant and native human urogastrones. The material eluted from the column was shown to have retained biological activity. When the eluted material was run on SDS/PAGE under reducing conditions an apparently homogeneous species of 5400 Da apparent molecular weight was seen. When examined on acid PAGE, 2 molecular species corresponding to beta and gamma urogastrone were observed.

Abstract

We have generated a panel of T-lymphocyte clones from a patient suffering from the hyper IgE syndrome, and have attempted to correlate the ability of each to help IgE responses in vitro with the profile of lymphokines secreted after mitogenic stimulation. Clones which showed positive IgE helper activity released larger amounts of interleukin-4 (IL-4) than the non-helpers, which tended to release more interleukin-2 (IL-2). Surprisingly, all clones released moderate amounts of gamma interferon (IFN), which has been shown to inhibit the action of IL-4 on B cells. The clones were analysed by indirect immunofluorescence using monoclonal antibodies to CDw29 and CD45R (4B4 and 2H4 respectively). Those T cells which could provide strong helper activity for all isotypes, expressed high levels of CDw29 and low CD45R. These data suggest that these CD4-positive T cells expressing surface antigen of the 'memory' subset i.e. CDw29, are involved in IgE isotype regulation by virtue of their ability to secrete IL-4 upon antigenic stimulation.
