New method exposes structures inside “rainbow” of brain cells

Molecules from alpacas may enable scientists to identify cell types in the brain while also revealing their interior structures. The method may help researchers better visualize how the brain is wired in autism. Researchers often stain tissue with fluorescent antibodies to certain proteins so they can identify cell types. They can also use electron microscopy to view the tissue’s internal structure.

But the two techniques can’t be used on the same sample. The former requires chemicals that often break down cells. Electron microscopy involves thinly slicing the sample, and staining the numerous slices afterwards is prohibitively laborious. Scientists have engineered brain cells to produce fluorescent proteins or made tags that are visible in an electron microscope. But these methods can label only about three cell types per sample. The new technique lets researchers tag tissue with up to 10 markers.

The researchers stained sections of mouse brain using fluorescent ‘nanobodies’ antibody fragments typically derived from camelids, the mammalian family that includes camels, alpacas and llamas. Because of their small size, nanobodies can infiltrate tissue without it needing to be pretreated with harsh chemicals. The team created images of the stained tissue with a fluorescent microscope. They then sliced the samples into 50-nanometer-thick segments and scanned those with an electron microscope. Using computer software, they aligned both sets of images based on landmarks such as blood vessels.

The resulting images highlight four cell types, including star-shaped support cells called astrocytes and immune cells called microglia, each labeled with different colors. The fluorescent nanobodies penetrate more than 100 micrometers into the block of tissue. By contrast, antibody markers stain only the surface. The images show organelles such as mitochondria and microtubule bundles. The researchers could also make out the long filaments that extend from neurons, and the vesicles at the end of them that hold chemical messengers. The nanobody method could reveal differences in cell structure and the distribution of cell types in the autism brain.

The ultimate goal is to stain a sample with hundreds of colors by developing more nanobodies and combining fluorescent dyes.

Taking a closer look

Cryo-electron microscopy, an emerging technology that can show the structure of molecules down to the atomic level with more clarity than ever before. Years ago, we were able to see only the general areas where the proteins were as blobs on a screen but now it is possible to see the atoms within those blobs. This could help researchers design new drugs that better target diseases or create new compounds that speed up or slow down chemical reactions.

Electron microscopes use a beam of electrons instead of rays of light to create an image. Because electrons have a much shorter wavelength than visible light, such microscopes can provide better resolution of molecules at the atomic level. What we are looking at is a projection of how the electrons interact with the sample. Since everything is made of electrons, they repel each other. Thus, what is generating is a sort of two-dimensional projected image of your sample. Cryo-EM is a modification of the standard electron microscope that involves freezing a sample in solution so rapidly that the surrounding water forms a thin, glass-like layer instead of crystallizing. Scientists can then take multiple images of that frozen sample and piece them together to create a remarkably clear 3-D image.

Seeing the shape and arrangement of the molecule could help scientists better understand how these molecules work. Some proteins operate very much like tiny machines, using a chemical process to create mechanical energy. They have very mechanical properties, so when we see the whole thing, then we immediately start to see what the pieces are and how they move. With cryo-EM scientists can take various images of these proteins and put them together like a stop-action movie to see how those mechanical properties work.

As technology has improved it’s opened up new areas of research. Pharmaceutical companies, for example, are using cryo-EM to map out the sites where drugs can bind to the target cells, so they can better identify which drugs might affect those cells and learn what part of the protein they interact with.

Tiny straws improve molecule delivery

Researchers have found what they believe may be a better way to deliver molecules directly into human cells they require to manipulate. “Nanostraws” are small glass-like protrusions that poke equally little holes in cell walls before releasing their cargo that is completed more safely and with efficiency than existing strategies.

They say breakthrough might speed up medical and biological research and in the future will improve gene therapy for cancer and diseases of the eyes and immune systems. Scientist expertise with nanomaterials was the key to the new approach, that improves on the method referred to as electroporation, whereby an electrical current is employed to form holes in cell walls.

Existing electroporation strategies will be imprecise, usually killing several of the cells researchers try to work with. Nanostraws are more economical as a result of their long, narrow profile helps concentrate electrical currents into a really tiny space.

They’re additionally a far better possibility than approaches based mostly around using viruses or alternative chemicals to carry molecules across cell walls. The researchers initially tested their technique on animal cells sitting atop a bed of nanostraws. when they turned on the electrical current, the nanostraws opened little, regularly sized pores within the cell membrane: enough to permit molecules in, however not enough to try to serious injury. the current drew molecules straight into the cell, further increasing the speed and precision of the method.

The question at that time was whether or not the technique would be as effective on the kinds of human cells clinicians would wish to manipulate to treat diseases. They successfully delivered molecules into 3 human cell types as well as mouse brain cells, all of that had proven difficult to work within the past. The technique was fast and killed fewer than 100% of cells, an enormous improvement on normal electroporation, they say.

The next step is to test it with human immune cells, that are among the hardest to figure with.

The study reveals how a small molecule promotes the removal of excess cholesterol

Experts have discovered the structure of the activated form of an enzyme that helps to return excess cholesterol to the liver.

The analysis reveals how a drug-like chemical stimulates the action of the lecithin: cholesterol acyltransferase (LCAT) enzyme. It also recommends that future drugs using the same mechanism could be used to restore LCAT function in people with familial LCAT deficiency (FLD), a rare inherited disease that settles them at risk of eye problems, anemia, and kidney failure.

LCAT helps high-density lipoprotein (HDL) known as the good cholesterol to remove cholesterol from the blood by converting the lipid into a form that is accessible to package and transport. There are more than 90 known mutations in LCAT, which can cause either a partial loss of activity (known as 'fish-eye disease') or full loss (FLD). Boosting LCAT activity may be beneficial in treating people with coronary heart disease and LCAT deficiencies, but the mechanisms by which it can be activated are poorly understood.

In this study, structural biology is used to understand how a patented LCAT activator binds to LCAT and how it promotes cholesterol transport. It was also studied if the compound could help recover the activity of LCAT enzymes that have commonly observed mutations seen in FLD.

The researchers used X-ray crystallography to look at the LCAT enzyme stabilized in its active state with two different chemicals, the activator molecule, and a second compound that mimics a substrate bound to the enzyme. The two chemicals had more of an effect on the protein when presented together than when presented separately, which suggested that they bind to the enzyme in different places.

Further analysis has found that the activator molecule, unlike other known LCAT activators, binds to a region close to where HDL attaches. However, the activator did not help LCAT bind to the HDL more efficiently, which led the researchers to speculate that it instead helps to transfer cholesterol and lipids into the catalytic center of the enzyme, so that it can convert it into cargo for transport in HDL.

On establishing this mode of action, the researchers tested whether this molecule could help recover the cholesterol-transport function of a mutant LCAT enzyme. They made a version of the enzyme with a mutation commonly seen in FLD patients and then tested its ability to bind to HDL and convert cholesterol in the presence or absence of the activator molecule. They were delighted to find that the activator could partly reverse the loss of activity in the mutant enzymes, resulting in comparable cholesterol conversion to the normal enzyme.

The results will help scientists to design compounds that can better target LCAT so that they might be of therapeutic benefit for heart disease and FLD patients. Future efforts will be to examine whether patients with other LCAT genetic mutations could benefit from the compounds used in this study and to design molecules with improved pharmacological properties for further development.

Structural study of antibiotic opens the way for new TB treatments

A new analysis of the structure and function of the naturally-occurring antimicrobial agent tunicamycin has shown ways to produce new, safe antibiotics for Mycobacterium tuberculosis and other disease-causing bacteria.

Tunicamycin is an antimicrobial produced by different types of bacteria, but it is inappropriate for use in humans because it is also toxic to animal cells.

In a new investigation, researchers studied the mechanism behind Tunicamycin's toxicity and pronounced that it acted upon a gene called DPAGT1, which is capable of producing an enzyme required in glycoprotein biosynthesis. This is a gene that often mutates, leading to rare genetic diseases.

By analyzing the interaction of Tunicamycin with this protein the researchers were able to know how it acts upon cells. The researchers also altered its structure to create new analogs of the antibiotic, several of which were useful in treating Tuberculosis (TB) in mice, while also being less toxic than alternative medicine presently wont to treat the malady.

TB poses a growing threat as our arsenal of drugs to treat it is rapidly working out. An exciting outcome from this research work is the development of a promising new class of antimicrobial drug.

This research represents a really beautiful synergy of the striking structural biology of a key human enzyme and the redesign of one of the most famous natural products in science, now redesigned to form a brand new family of antibiotics for TB.

Tuberculosis is a disease caused by the bacteria Mycobacterium tuberculosis, which causes around 1.3 million deaths each year globally. The huge majority of deaths occur in emerging countries where poor sanitation and access to healthcare compound the problem. Antibiotic resistance is turning into a major drawback with TB as several strains of the disease have become resistant to a variety of the drugs available, and a few strains resistant to all of them.

In the future, being able to design new drugs in a way that ensures their lower toxicity compared with rivals represents a real game-changer in the search for new treatments.
