We describe the properties of BG505 SOSIP.664 HIV-1 envelope glycoprotein trimers produced under current Good Manufacturing Practice (cGMP) conditions. These proteins are the first of a new generation of native-like trimers that are the basis for many structure-guided immunogen development programs aimed at devising how to induce broadly neutralizing antibodies (bNAbs) to HIV-1 by vaccination. The successful translation of this prototype demonstrates the feasibility of producing similar immunogens on an appropriate scale and of an acceptable quality for Phase I experimental medicine clinical trials...

Bombyx mori is one of the key lepidopteran model species, and is economically important for silk production and proteinaceous drug expression. Baculovirus and insect host are important natural biological models for studying host-pathogen interactions. The impact of Bombyx mori nucleopolyhedrovirus (BmNPV) infection on the proteome and acetylome of Bombyx mori ovarian (BmN) cells were explored to facilitate a better understanding of infection-driven interactions between BmNPV and host in vitro. The proteome and acetylome were profiled through 6-plex Tandem mass tag (TMT) labelling-based quantitative proteomics...

OBJECTIVE: Patients with genetic generalized epilepsy (GGE) have subtle morphologic abnormalities of the brain revealed with magnetic resonance imaging (MRI), particularly in the thalamus. However, it is unclear whether morphologic abnormalities of the brain in GGE are a consequence of repeated seizures over the duration of the disease, or are a consequence of treatment with antiepileptic drugs (AEDs), or are independent of these factors. Therefore, we measured brain morphometry in a cohort of AED-naive patients with GGE at disease onset...

Genetic manipulation of bacterial spores of the genus Bacillus has shown potential for vaccination and for delivery of drugs or enzymes. Remarkably, proteins displayed on the spore surface retain activity and generally are not degraded. The heat stability of spores coupled with their desiccation resistance makes them suitable for delivery to humans or to animals by the oral route. Despite these attributes one regulatory obstacle has remained regarding the fate of recombinant spores shed into the environment as viable spores...

Swinholides are 42-carbon ring polyketides with a twofold axis of symmetry. They are potent cytotoxins that disrupt the actin cytoskeleton. Swinholides were discovered from the marine sponge Theonella sp. and were long-suspected to be produced by symbiotic bacteria. Misakinolide, a structural variant of swinholide, was recently demonstrated to be the product of the symbiotic heterotrophic proteobacterium. Here we report the production of swinholide A by an axenic strain of the terrestrial cyanobacterium Nostoc sp...

Malaria is one of the major global health challenge with 300 million new cases annually. The best regimen for treating Plasmodium falciparum induced malaria is based on artemisinin and its derivatives which were prescribed as artemisinin combination therapy (ACT). These are highly effective drugs resulting in rapid clearance of parasites even in severe P. falciparum induced malaria patients. However, from the past few years parasites resistant to ACT's have begun to emerge in various parts of the world such as Cambodia and Greater Mekong Subregion...

Tumor cell chemoresistance is a major challenge in cancer therapeutics. Major select metal-based drugs are potent anticancer agents yet they exhibit undesirable side-effects and are effective against only a few types of cancers. A need, therefore, arises for new metallodrugs with an improved spectrum of efficacy and lower toxicity. Development of anticancer drugs based on antitumor metals is currently a very active field, with considerable efforts having been made toward elucidating the mechanisms of immune action of complex metalloforms and optimizing their immunoregulatory bioactivity through appropriate structural modification...

Background Gene therapy represents the therapeutic delivery of nucleic acid polymers into a patient's cells with the aim of treating an underlying disease. Over the past 2 decades this new therapy has made substantial progress owing to better understanding of the pathobiologic basis of various diseases coupled with growth of gene transfer biotechnologies. The eye, in particular, represents a suitable target for such therapy due to the immune privilege provided by the blood-ocular barrier, the ability to directly visualize, access and locally treat the cells and the minimal amount of vector needed given the size of this organ...

There has been increasing interest in the development of small molecules that can selectively bind to G-quadruplex DNA structures. The latter have been associated to a number of key biological processes and therefore are proposed to be potential targets for drug development. In this paper we report the first example of a reduction-activated G-quadruplex DNA binder. We show that a new octahedral platinum(IV)-salphen complex does not interact with DNA in aqueous media at pH 7.4; however, upon addition of bio-reductants such as ascorbic acid or glutathione, the compound readily reduces to the corresponding square planar platinum(II) complex...

BACKGROUND: Cutaneous leishmaniasis, caused by a parasitic infection, is considered one of the most serious skin diseases in many low- and middle-income countries. Old World cutaneous leishmaniasis (OWCL) is caused by species found in Africa, Asia, the Middle East, the Mediterranean, and India. The most commonly prescribed treatments are antimonials, but other drugs have been used with varying success. As OWCL tends to heal spontaneously, it is necessary to justify the use of systemic and topical treatments...

The translationally controlled tumor protein (TCTP) is a highly conserved protein that is regulated due to a high number of extracellular stimuli. TCTP has an important role for cell cycle and normal development. On the other side, tumor reversion and malignant transformation have been associated with TCTP. TCTP has been found among the 12 genes that are differentially expressed during mouse oocyte maturation, and an overexpression of this gene was reported in a wide variety of different cancer types. Its antiapoptotic effect is indicated by the interaction with several proapoptotic proteins of the Bcl-2 family and the p53 tumor suppressor protein...
