In the present study, we used phage display to develop an engineered antibody domain, called SD1, recognizing an epitope at the C-terminus of mesothelin. This epitope does not overlap with any previously developed mesothelin therapeutic antibodies in preclinical or clinical development. SD1-hFc shows strong CDC and ADCC activity against mesothelin-expressing cancer cells in vitro and causes growth inhibition of human tumor xenografts in nude mice in vivo. Our results suggest that the SD1 single-domain antibody represents a new class of antimesothelin mAbs and is a promising therapeutic candidate for novel mesothelin-targeted therapy.. We isolated the SD1 domain by phage panning on a C-terminal 50-residue peptide of mesothelin and showed that the antibody binds native mesothelin proteins in cancer cells. This region has never been accessed by any known antimesothelin antibodies. Our data show that CDC triggered by SD1-hFc depends on the specific new epitope because the HN1 human IgG (specific for ...

We designed a vector for the bacterial expression of recombinant antibodies fused to a double tag composed of 6xHis and the EPEA amino acid sequence. EPEA sequence (C tag) is tightly bound by a commercial antibody when expressed at the C-term end of a polypeptide. The antigen is released in the presence of 2 M MgCl2. Consequently, constructs fused to the 6xHis-C tags can be purified by two successive and orthogonal affinity steps. Single-domain antibodies were produced either in the periplasmic or in the cytoplasmic space of E. coli. Surprisingly, the first affinity purification step performed using the EPEA-binding resin already yielded homogeneous proteins. The presence of the C tag did not interfere with the binding activity of the antibodies, as assessed by FACS and SPR analyses, and the C tag was extremely effective for immunoprecipitating HER2 receptor. Finally, the Alexa488-coupled anti-C tag allowed for simplification of FACS and IF analyses. These results show that a tag of minimal dimensions

The hepatocyte growth factor (HGF) and its receptor, c-Met, are implicated in many human cancers to promote tumor proliferation, migration, invasion and angiogenesis. Dysregulation of the HGF/c-Met pathway is known to correlate with poor prognosis. In recent years, multiple anti-cancer agents have been developed interfering at different levels in the HGF/c-Met pathway. Here, we investigated the in vitro and in vivo efficacy of a novel Nanobody effectively antagonizing c-Met. Nanobodies are therapeutic proteins based on the smallest functional fragments of heavy chain antibodies, naturally occurring in Camelidae. The Nanobody platform allows designing modular drugs, including multivalent, biparatopic and bifunctional molecules. The anti-c-Met Nanobody is a bispecific Nanobody that comprises two building blocks, one targeting c-Met and one binding human serum albumin for half-life extension purposes. In vitro characterization revealed that the Nanobody is able to specifically and completely ...

Preventing the spread of infectious diseases remains an urgent priority worldwide, and this is driving the development of advanced nanotechnology to diagnose infections at the point of care. Herein, we report the creation of a library of novel nanobody capture ligands to detect p24, one of the earliest markers of HIV infection. We demonstrate that these nanobodies, one tenth the size of conventional antibodies, exhibit high sensitivity and broad specificity to global HIV-1 subtypes. Biophysical characterization indicates strong 690 pM binding constants and fast kinetic on-rates, 1 to 2 orders of magnitude better than monoclonal antibody comparators. A crystal structure of the lead nanobody and p24 was obtained and used alongside molecular dynamics simulations to elucidate the molecular basis of these enhanced performance characteristics. They indicate that binding occurs at C-terminal helices 10 and 11 of p24, a negatively charged region of p24 complemented by the positive surface of the nanobody

Immunization by a large molecular assembly, such as the TP901-1 baseplate, proved to be an efficient technique to obtain nanobodies against the exposed surface of the various molecular components of the complex to evaluate the effect of binding on infectivity. Although the three components of the baseplate were targeted, BppU and BppL dominated the immunological response, with some epitopes being clearly favored. The head domain of BppL and its saccharide binding groove were targeted by two TP901-1-neutralizing-strongly binding-nanobodies. This groove was also found to be the epitope of a nanobody-neutralizing (VHH5) phage p2 (14, 15, 24, 26). This groove-directed mode of binding is a characteristic of nanobodies, because this mode has also been observed on several occasions for catalytic crevices of enzymes (22, 34, 35). Noteworthy, nanobodies are distinctly different from DARPINs, because this latter family of artificial binders binds preferentially to flat or convex surfaces. We observed this ...

Results: No drug-related adverse events occurred in this study. The mean effective dose was 8.84 × 10−3 ± 9.33 × 10−4 mSv/MBq (3.59 ± 0.74 mSv per patient). Tracer uptake was observed in the kidneys, spleen, liver, and bone marrow. SPECT primary tumor-to-blood-pool ratios (T:BP) varied from 1.24 to 2.3 (mean, 1.79) at 1 h and 1.24 to 3.53 (mean, 2.22) at 2 h (P = 0.005). Two-hour primary T:BP ratios correlated with PD-L1 immunohistochemistry results (r = 0.68, P = 0.014). Two-hour T:BP was lower in tumors with ≤1% PD-L1 expression (1.89 vs. 2.49, P = 0.048). Nodal and bone metastases showed tracer uptake. Heterogeneity (,20%) between primary tumor and nodal T:BP was present in 4 of 13 patients ...

Nanobodies are miniature antibodies derived from naturally circulating heavy-chain only antibodies in llamas. Over the past years, nanobodies and their applications have expanded enormously, both in basic research but also in drug development.. Nanobodies have proven to be well suited as protein stabilizers, which is particularly important during crystallization of a protein where millions of molecules have to arrange in a well-defined lattice. In this way, nanobodies can act as crystallization chaperones.. In an X-ray diffraction experiment, a critical piece of information - called the phases - is lost, which makes it difficult to determine new crystal structures. To overcome this phase problem in crystallography, heavy atoms are needed in the crystal. However, it is challenging to insert heavy atoms into a crystal. The scientists at Aarhus University used a nanobody as the vehicle for introducing mercury atoms. They developed a method to site-specifically label the nanobody with a heavy atom, ...

During that holiday musing, Heo had figured out at which cysteine residues he could split the nanobody to generate two inactive parts that do not bind a targeted protein. He checked the nanobody structure, and experiments got underway. The split structure lets an experimenter use light to, for example, activate or inhibit a protein at the cell membrane, at an organelle or in the cell nucleus. When the nanobody halves are separate, its like having only one chopstick for a meal, he says. Work only gets done when the other half enters the scene.. ...

RFP Selector is based on a high-affinity single-domain antibody (sdAb) that is covalently immobilized on 4% cross-linked agarose beads. The innovative, oriented and selective attachment via a flexible linker guarantees a high accessibility of the sdAbs and largely eliminates batch-to-batch variations. RFP Selector features high affinity and superior capacity for RFP fusion proteins while showing negligible non-specific background.

Synthetic PhotoBioChemistry. To attain ,30nm super-resolution fluorescence imaging on the dynamic nanoarchitecture of a biological system it will be necessary to develop small probes with high-specificity, minimal disruption of the target molecule behaviour and photophysics compatible with SR microscopy. The resolution attainable with SR imaging is influenced by a number of factors including the size of the labelling moieties used to target fluorescent dye molecules to the protein of interest: The smaller the labelling structure used, the closer the fluorophores location correlates to that of the target molecule, and the greater the precision that can be attached to its localisation. In addition, small labelling molecules such as single-domain antibodies (nanobodies) can more easily access target domains within densely packed environments with minimal stearic hindrance when compared to large antibody complexes. Our FlAsH-PALM approach (Lelek et al. 2012) has demonstrated that small probes are ...

Anti-oxidants have recently become a buzzword in nutrition and cancer circles. There are a lot of news stories and nutritional supplement advertisements touting anti-oxidants as magic bulletsthat will prevent the occurrence and/or spread of oral and other kinds of cancer. In truth, of course, there is no magic bullet to prevent cancer - but there IS a growing body of research that shows that anti-oxidants actually provide a kind of defense against this disease. To understand how, it is important to first examine another set of compounds known as free radicals. The human body is made up of many different types of cells, which in turn are composed of different types of molecules. Molecules consist of atoms joined by chemical bonds, formed by the electrons in an atoms outer shell. Normally, these bonds maintain stability; if they do split, they do so in balanced reactions. When weak bonds split, however, they may do so unevenly, creating what scientists call free radicals, or loose, unbalanced ...

By Robert Whitaker. The timing of Robert Whitakers Anatomy of an Epidemic, a comprehensive and highly readable history of psychiatry in the United States, couldnt be better. Salon.com. Anatomy of an Epidemic offers some answers, charting controversial ground with mystery-novel pacing. TIME.com. Lucid, pointed and important, Anatomy of an Epidemic should be required reading for anyone considering extended use of psychiatric medicine. Whitaker is at the height of his powers. Greg Critser, author of Generation Rx. Why are so many more people disabled by mental illness than ever before? Why are those so diagnosed dying 10-25 years earlier than others? In Anatomy of an Epidemic investigative reporter Robert Whitaker cuts through flawed science, greed and outright lies to reveal that the drugs hailed as the cure for mental disorders instead worsen them over the long term. But Whitakers investigation also offers hope for the future: solid science backs natures way of healing our mental ills through ...

When guitar solos and leads are utilized they are done in a very melodic fashion and the music also brings in the heaviness of metal and noise rock while some tracks also bring in elements of punk and the music also has a lot of roots in the 90s while also sounding very modern at the same time and there is also a brief use of psychedelic sounds while spoken word parts are also added on some of the tracks and all of the songs stick to either a slow or mid paced musical direction and acoustic guitars are added onto the last track ...

This is because muscles need an immediate source of protein to supply their needs, especially during a heavy workout. With that, you need to opt for protein powders, as they give the quickest and most absorbable type of proteins to work and repair your body tissues. In order to find out which powdered proteins are best for you, just visit your personal trainer or sports nutritionist.. You can also visit a sports house in your area or GNC stores. Now, if you dont just have the right budget to buy these powdered proteins, which can be expensive by the way, you can opt for egg whites. The only thing that you should remember is this: you have to eat them raw and fresh. Yes, you can get the most amino acids in raw fresh eggs as compared to cooking them. The reason for this is because as soon as you cook the egg, the structure of its proteins changes significantly, making it less absorbable.. So manipulating an egg white, even if you shake, blend or stir them has effects that you may never know. In ...

Hello, I have a lot of problems with the preview in adobe premiere pro and quicktime when it comes to color grading. These problems I experienced on different computer running Mac os x and different monitors calibrated or not. The issue is that the footage (h.264 / AVCHD) no matter if it´s from a 5d or a sony a7s looks alway more saturated and more punchy in the preview of premiere then after exporting and opening in quicktime. I think it´s a gamma problem. the thing is when i use magic bullet and the magic bullet looks preview inside premiere, it looks the same then in quicktime. when i use vls to playback the footage it looks the same then the preview of premiere pro. i made an example foto with four pictures. it´s a slight difference but if u look careful you will see it. it really drives me crazy. does anybody have the same experience or a solution? thank you, ben ...

I solved that dilemma in savvy style a week ago when I bought a magic bullet type of mini-blender at Macys. Belle Cucina is the brand name, and whereas the Magic Bullet runs around $79 retail, this runs $49 retail. It was on special for $19! The great thing is that I put all the stuff into the container at night (powder, fish oil, yogurt, frozen fruit, etc.) and he just pulls that out in the morning and sticks it in the nice small blender and Voila! A healthy, DELICIOUS shake and VERY easy to clean. It has to taste good or my husband will not drink it. He could be dying and he would not drink it. Me, on the other hand, will stomach just about anything if its good/healthy for me. Thats what happens when you are the daughter of a German nurse ...

This Editorial discusses the potential of nanoconstructs has to overcome the growing problem of antibiotic resistance in bacteria.

O2max, a previous study used seven bouts of 30 s interspaced with 15 s of rest.13 In addition, another interesting example of the possible influence of the control of intensity of effort on the results might be found in Ramos et al.86 While the protocol was reported to involve four bouts of 4 min at 85%-95% of HRpeak with 3 min intervals, the participants took 2 min to reach the targeted intensity. Therefore, the protocol seems to have involved 2 min of the actual prescribed intensity of effort. In other words, the time at target intensity of effort was not reached as planned, resulting in a lower effort to rest ratio than intended. We would like to note that these individual observations do not invalidate or question the merit of previous studies. These are only some aspects that might explain the large inconsistency among the results of interval training and which we must consider when analysing and reproducing previous studies.. Our results found that the effect of interval training protocols ...

None of the current superresolution microscopy techniques can reliably image the changes in endogenous protein nanoclustering dynamics associated with specific conformations in live cells. Single-domain nanobodies have been invaluable tools to isolate defined conformational states of proteins, and we reasoned that expressing these nanobodies coupled to single-molecule imaging-amenable tags could allow superresolution analysis of endogenous proteins in discrete conformational states. Here, we used anti-GFP nanobodies tagged with photoconvertible mEos expressed as intrabodies, as a proof-of-concept to perform single-particle tracking on a range of GFP proteins expressed in live cells, neurons, and small organisms. We next expressed highly specialized nanobodies that target conformation-specific endogenous β2-adrenoreceptor (β2-AR) in neurosecretory cells, unveiling real-time mobility behaviors of activated and inactivated endogenous conformers during agonist treatment in living cells. We showed ...

Protein Production UK (PPUK) is a new initiative in the Research Complex at Harwell that addresses sample preparation for challenging proteins and multi-component complexes. PPUK will be part of the Rosalind Franklin Institute and closely linked to the Central facilities on the Harwell campus. PPUK aims to develop new and innovative methods and to work in partnership with academic groups and industry to enable uptake of the technology. PPUK has an established pipeline for protein production based on the technology developed by the Oxford Protein Production Facility (OPPF), involving construction of multi-purpose vectors (e.g. for producing complexes, and membrane proteins), high-throughput expression screening in different cell hosts (microbial, insect and mammalian cells) combined with scale-up to multi-litre culture volumes and downstream processing. New technology platforms that are under development include production of single-domain antibodies for the stabilisation of membrane proteins for ...

Checkpoint inhibitors have revolutionized cancer therapy but only work in a subset of patients and can lead to a multitude of toxicities, suggesting the need for more targeted delivery systems. Because of their preferential colonization of tumors, microbes are a natural platform for the local delivery of cancer therapeutics. Here, we engineer a probiotic bacteria system for the controlled production and intratumoral release of nanobodies targeting programmed cell death-ligand 1 (PD-L1) and cytotoxic T lymphocyte-associated protein-4 (CTLA-4) using a stabilized lysing release mechanism. We used computational modeling coupled with experimental validation of lysis circuit dynamics to determine the optimal genetic circuit parameters for maximal therapeutic efficacy. A single injection of this engineered system demonstrated an enhanced therapeutic response compared to analogous clinically relevant antibodies, resulting in tumor regression in syngeneic mouse models. Supporting the potentiation of a ...

After 40 years of practice, give or take, this was a first. A new patient in his 20s arrived in the office with an elevated eosinophil count. Just to remind you these white blood cells are drawn to sites like the lungs in allergic asthma and the gastric tract. Normally they are a potent weapon against parasites. When there are no parasites, they protect against the wrong things, resulting in short-term distress and long-term damage.. This patients most grievous complaint was a symptom I dont normally associate with elevated eos, but after getting batted from one specialist to another, one of these doctors, noting the high numbers, recommended that he see an expert.. So how did you find me? I asked him. I dont think of myself as an expert.. I Googled and it said that eosinophils were discovered by Paul Ehrlich.. I took out a book and turned to an entry on my namesake that said he died in 1915. Obviously he had never heard of the Magic Bullet, not even the movie.. Are you related at ...

I think most of us fail to appreciate the wealth of standing information and advice built into the sites of the major cancer organisations. Theres a lot to be found, for instance, by exploring this ACS site, e.g. by following some of the links in the blue side-bar, to the left of this message. As I write, under Cancer information is a short piece entitled Cancer Drugs: Long Odds and Magic Bullets which will interest some here.. It talks about targeted treatment and also links to another interesting earlier piece in April, in the same column entitled The Future is Now: Personalized Medicine. Among useful bits of info there are these snippets and I begin with a bit that commended itself to me as sage advice:. Healthy living makes a difference. Our increased understanding of the genetic basis of disease has helped us realize how important it is that we take good care of our bodies. Smoking, obesity, and alcohol kill by causing DNA damage or exploiting genetic weakness. Exercise and a ...

DNA operates through RNA, and when RNA interference was discovered in 1998, it seemed like a magic bullet that could fight disease by specifically shutting down problematic genes. That promise was difficult to achieve, and no FDA-approved RNAi medicine has yet reached the market, although two are in the final phase of clinical trials.. In general, the short strands of designer RNA used in RNAi either target the unwanted RNA for destruction, or clog it up so it cant produce a protein. The process by which RNAi splits messenger RNA, is a natural process, Lewis says. Almost all cells have this capability. Its another level of control over gene expression.. In gene expression, DNA makes RNA, and RNA makes protein.. During the early development of RNAi, the short strands of RNA that were injected into the body usually were excreted, producing no benefit. The result was very expensive pee, Lewis says.. But when Lewis and others at Mirus invented a system to connect the strand of RNA to a ...

Dear Dr. Cooper:. I am writing in response to an article that I read that was in the January 2001 NSDA newsletter, written by Dr. Robert Bastian, MD at Loyola University, in Chicago.. The first thing that struck me about the article was that Dr. Bastian was admitting that there are less than favorable results with Botox. In a sense this is a good thing, because someone with SD does need to know that Botox is far from the magic bullet treatment it can be made out to be by doctors and some patients. Far too many people in my opinion go for their initial injection without first looking into the side effects, whether they be physical or mental/emotional.. After reading the article over a couple of times I had to wonder Why is he writing an article on SDs negative experiences with Botox? I began thinking back to all the people with SD that I knew that have experienced an emotional roller coaster ride. One shot good result; next shot no result over and over it goes. Could it be that these poor ...
