Jena researchers unravel secrets of chemical language between algae and bacteria

It is a gruesome spectacle that meets the eyes of Prasad Aiyar as he looks down the microscope. The doctoral candidate from India, who came to Jena to do his Master's degree in Molecular Life Sciences, examines the species Chlamydomonas reinhardtii on a microscope slide.

Research reveals fundamental process used by immune system to recognize invading pathogens

The body's homeland security unit is more thorough than any airport checkpoint. For the first time, scientists have witnessed a mouse immune system protein frisking a snippet of an invading bacterium. The inspection is far more extensive than researchers imagined: the immune system protein, similar to those in humans, scans the bacterial protein in six different ways, ensuring correct identification.

An alternative approach to augmenting the effect of antibiotics in chronic CF lung infections

There are about 77,000 people known to have cystic fibrosis. That's from the various cystic fibrosis registries available globally. The World Health Organization suggests that this number may be low, because there's no reporting on cystic fibrosis from the developing world. The accepted number, at the moment, is about 80,000. That's the one that is used for most of the work that's being done on cystic fibrosis.

Skin-applied microneedle patch boosts immunization to seasonal flu vaccine recipients, study finds

A boosting skin vaccination with a biodegradable microneedle patch and protein constructed from sequences of influenza virus subtypes could improve the effectiveness of conventional influenza vaccines, according to a study led by Georgia State University.

Findings could influence ways to control bacterial growth on medical and other surfaces

A flexible tail allows swimming bacteria to thin the surrounding liquid and to free themselves when trapped along walls or obstacles.

Yemen facing serious cholera outbreak

Yemen has been torn apart with violence that has led to widespread famine and now it has another demon to face. International health authorities last Saturday announced that the world now faces one of its worst cholera outbreaks.

Cold Spring Harbor Laboratory Press publishes new book on key aspects of ciliary biology

Nearly every cell in the human body has one or more protrusive structures called cilia or flagella.

New UGA research finds pathogen's motility activates immune response

Until now, a pathogen's ability to move through the body has been overlooked as a possible trigger of immune response, but new research from the University of Georgia College of Veterinary Medicine found that motility will indeed alarm the host and activate an immune response.

Disrupting bacteria's motility can stop infections

When looking at bacteria, you typically see also flagella: long hairs that protrudes from the bacteria's body.

Researchers discover how specific gene inhibits bacterial invasion of colonic epithelia

A group of researchers at Osaka University elucidated how a gene named Ly6/Plaur domain containing 8 (Lypd8) inhibits bacterial invasion of colonic epithelia, regulating intestinal inflammation. This achievement may lead to the development of drugs for ulcerative colitis.

Researchers show how bacterial colony protects itself against toxic substances

Bacterial populations move over surfaces in coordinated way known as swarming, which allows them to spread further over organs and tissues and increases the virulence of the infection. This movement is driven by the action of the flagella and the chemoreceptors, the systems responsible for identifying chemical compounds in the environment and which are anchored at the poles of their cells, forming highly organised structures, of which the protein CheW forms part.

Researchers find how microtubules, motor proteins assemble into macroscopic networks

What bones are to bodies, the cytoskeleton is to cells. The cytoskeleton maintains cellular structure, builds appendages like flagella and, together with motor proteins, powers cellular movement, transport, and division. Microtubules are a critical component of the cytoskeleton, vital for cell division and, because of that, an excellent target for chemotherapy drugs.

Carbapenem-resistant Enterobacteriaceae: an interview with Dr. Michael Dudley

Enterobacteriaceae refer to the family of bacteria such as E. coli and Klebsiella that are bacterial pathogens most frequently associated with hospital-acquired infections

Injectable microwheels can effectively treat arterial blockages

Biomedical microwheel research conducted by members of the Colorado School of Mines Department of Chemical and Biological Engineering has been published in Nature Communications.

E. coli can move faster and farther in syrup-like fluids than in water, say Penn researchers

Swimming in a pool of syrup would be difficult for most people, but for bacteria like E. coli, it's easier than swimming in water. Scientists have known for decades that these cells move faster and farther in viscoelastic fluids, such as the saliva, mucus, and other bodily fluids they are likely to call home, but didn't understand why.

CWRU researcher receives $3.9 million grant for HIV research

A researcher at Case Western Reserve University School of Medicine has been awarded $3.9 million to determine if the combination of the human immunodeficiency virus (HIV) and drug abuse is a double kick in the gut, leading to organ damage throughout the body.

New study shows mechanism behind tubulin transport in cilia

Defective cilia can lead to a host of diseases and conditions in the human body--from rare, inherited bone malformations to blindness, male infertility, kidney disease and obesity. Scientists knew that somehow these tiny cell organelles become deformed and cause these diseases because of a problem related to their assembly, which requires the translocation of vast quantities of the vital cell protein tubulin.

Scientists develop 3D filming technique that reveals spread of malaria

Scientists have developed a 3D filming technique that could help inform research to stem the spread of malaria.

WUSTL engineers apply new imaging technique to understand brain’s biomechanics

The human body has a lot of jobs to do, and its mechanical features, such as strength and flexibility, are important to how well it does them. Washington University in St. Louis engineers are now applying a new imaging technique to a model of brain tissue to see how stiff or soft it might be.

Bacteria form biofilm to protect against immune system

Bacteria are life forms, which, like all other life forms, struggle for the best living conditions for themselves. Therefore they will try to avoid getting attacked by the human immune system, and therefore they have developed various ways to protect themselves from the human immune system.
