Scientists use genomics to track the outbreak of Yellow fever virus in São Paulo

Yellow fever virus is normally confined to the Amazon region, but the virus circulated in the Southeast of Brazil between 2016 and 2018, causing the worst epidemic and epizootic outbreaks there for decades. The Ministry of Health confirmed 2,251 cases of yellow fever in humans and 1,567 cases in monkeys in Brazil between December 2016 and June 2019.

Composition of virus communities is shaped by host genetic factors

Plants can be infected by multiple viruses at once. However, the composition of the pathogen community varies, even if individuals belong to the same species and the same population.

Researchers discover how tomato plants identify Cuscuta as a parasite

Working together with researchers from the University of Tübingen, the University of Tromsø, the UC Davis and the Sainsbury Laboratory in Norwich, biologists from Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) have discovered how tomato plants identify Cuscuta as a parasite.

Study shows memory T cells are formed earlier than previously thought

A person will acquire immunity to a specific disease when T cells develop into memory cells after making contact with pathogens.

Similarities between animal and plant immune systems go beyond sensing

Max Planck Institute for Plant Breeding Research (MPIPZ) and University of Cologne researcher Takaki Maekawa and colleagues have discovered that plants have independently evolved a family of immune proteins that are strikingly similar to animals.

“Nanobiologic” immunotherapy can train the immune system to eliminate tumor cells

Until recently, it was believed that the innate immune system, the body's first line of defense, lacked the ability to remember pathogens like the adaptive immune system.

SARS-Cov-2 spike proteins can directly impact the function of blood-brain barrier

Like a key, SARS-CoV-2 - the virus that causes coronavirus disease 2019 (COVID-19) - attaches to specific molecules on the host cell surface, opening gateways into the cell interior.

Human immune system may play a key role in shaping the microbiome composition

The gut is an unusually noisy place, where hundreds of species of bacteria live alongside whatever microbes happen to have hitched a ride in on your lunch.

Researchers receive $2.6 million grant to examine tau-glycan interactions involved in Alzheimer's disease

Tangles of misfolded tau proteins in the brain are closely associated with memory loss in patients with Alzheimer's disease.

Researchers develop new sensors to detect gene activity

A team of researchers have developed genetic sensors that are capable of detecting the activity of genes, instead of only the genes themselves.

Research on broadly neutralizing antibodies may lead to universal flu vaccine

New research from an immunology team at the University of Chicago may shed light on the challenges of developing a universal flu vaccine that would provide long-lasting and broad protection against influenza viruses.

Molecular communication may help increase the resistance of crop plants against parasitic plants

Cuscuta spp., also known as dodder, is a parasitic vine which grafts to the host plant using special suckers to obtain water, minerals and carbohydrates.

Study explores the impact of microbial immune diversity on dynamics of host-virus interactions

CRISPR-Cas serves as a key driving force of strain diversity in host-virus systems during an evolutionary fight between the host and virus.

Peptide therapy prevents overreaction of the immune system against infections

Individuals require enough action to remove offensive viruses or bacteria, but not so much that their body suffer a considerable damage.

A new protein discovered that repairs DNA

Researchers have identified a new protein that makes it possible to repair DNA. The protein in question is called cryptochrome.

Biofilms of major pathogenic bacteria can deform soft surfaces

The vast majority of bacteria in the world live on surfaces by forming structures called "biofilms". These communities host thousands to millions of bacteria of different types, and are so biologically complex and active that scientists describe them as "cities".

Study offers new insights how the plant tips stay free of virus

Plants are able to keep growing indefinitely because they have tissues made of meristems--plant stem cells--which have the unique ability to transform themselves into the various specialized cells that make up the plant, dividing whenever appropriate and producing new cells of whatever type as needed.

Researchers investigate the role of auxin in regulating pathogen gene expression

Scientists have long known that the plant hormone auxin controls many aspects of plant growth, development, and responses to the environment. Only more recently have they begun to understand that there is also a link between auxin and leaf spotting diseases.

Gut microbial development could be restored in C-section infants by fecal microbiota transplant

The human gut contains a diverse ecosystem of microbes: mainly bacteria, as well as viruses and fungi, termed the gut microbiota.

Researchers identify small molecules that target a structure within SARS-CoV-2 genome

SARS-CoV-2 is a virus that is responsible for causing COVID-19. This pathogen has now crippled economies, health care systems, and everyday lives across the world.
