Trinity Scientists Discover New Mechanisms Involved in Establishing Cellular Identity

A team of scientists led by those in Trinity College Dublin has discovered new mechanisms involved in establishing cellular identity, a process that ensures the billions of different cells in our bodies do the correct job.

Viruses Interact with a Far More Diverse Set of Hosts than was Previously Thought

Viruses are the most abundant and diverse biological entities on Earth, living in every type of habitat. In the ocean alone viruses are ten times more abundant than microbes.

Evolutionary Encounter of Two Protein Components Could Occur Entirely by Chance

Proteins are the key players for virtually all molecular processes within the cell. To fulfil their diverse functions, they have to interact with other proteins.

The “Hangry” Stage of Bacteria Cells

The word “hangry” describes individuals who become angry due to hunger. According to a recent study by Adam Rosenthal, PhD, an assistant professor in the department of microbiology and immunology, some bacteria cells experience hangry and release toxic substances into the body when they are denied certain nutrients.

Dengue Viruses Subvert Mosquito Biology to Tamp Down Human Immune Responses

The saliva of mosquitoes infected with dengue viruses contains a substance that thwarts the human immune system and makes it easier for people to become infected with these potentially deadly viruses, new research reveals.

First Steps Driving Antibiotic Resistance Discovered

Antibiotic resistance is a global health threat. In 2019 alone, an estimated 1.3 million deaths were attributed to antibiotic resistant bacterial infections worldwide.

Maternal vaginal microbiome does not substantially influence the infant stool microbiome

It has been a longstanding assumption that birth mode and associated exposure of newborns to their mothers' vaginal microbiome during delivery greatly affects the development of babies' gut microbiome.

Study reports a new target to fight against antibiotic-resistant pneumonia

Increases in multidrug-resistance in the bacteria Streptococcus pneumoniae have made it the fourth-leading cause of death associated with antibiotic resistance.

Myeloid cells contribute to a long-lived HIV reservoir, study shows

A subset of white blood cells, known as myeloid cells, can harbor HIV in people who have been virally suppressed for years on antiretroviral therapy, according to findings from a small study supported by the National Institutes of Health.

Monocytes harbor stable HIV DNA capable of infecting neighboring cells

To develop treatments that may one day entirely rid the body of HIV infection, scientists have long sought to identify all of the places that the virus can hide its genetic code.

Immune system’s aptitude in reducing reliance on antibiotics for treating infections

The removal of obsolete and damaged cell components by the body is crucial for fighting diseases like tuberculosis (TB), which establish themselves inside human cells, according to researchers from the Francis Crick Institute.

Understanding the cellular effects of antibiotics targeting cell wall biosynthesis

It is still unclear how antibiotics work to destroy bacteria. This knowledge, however, is required for the development of new antibiotics. That is exactly what is required because bacteria are becoming increasingly resistant to existing antibiotics.

Novel tool analyzes how immune cells respond to SARS-CoV-2 vaccination

A study discovered that the magnitude and quality of a key immune cell’s response to two doses of the Pfizer-BioNTech COVID-19 vaccine were significantly lower in individuals with earlier SARS-CoV-2 infection compared to individuals without previous infection.

Keeping lymph nodes in the body can boost the efficacy of cancer immunotherapy

Cancer treatment routinely involves taking out lymph nodes near the tumor in case they contain metastatic cancer cells.

Decreased viral infection severity in females linked to extra copy of epigenetic regulator

It has long been known that viral infections can be more severe in males than females, but the question as to why has remained a mystery – until possibly now.

First molecular images of olfaction sets the stage to create novel smells

Breaking a longstanding impasse in our understanding of olfaction, scientists at UC San Francisco (UCSF) have created the first molecular-level, 3D picture of how an odor molecule activates a human odorant receptor, a crucial step in deciphering the sense of smell.

Bile salt hydrolase cocktails may offer a new approach to inhibit C. diff colonization

Not all probiotics are created equal. In a new study, researchers found that certain enzymes within a class known as bile salt hydrolases (BSHs) can restrict Clostridioides difficile (C. diff.) colonization by both altering existing bile acids and by creating a new class of bile acids within the gut's microbial environment.

Novel technology easily detects active Mycobacterium tuberculosis infection antibodies

A team of faculty from Wayne State University has discovered new technology that will quickly and easily detect active Mycobacterium tuberculosis (TB) infection antibodies.

Analyzing the antimicrobial resistance profile of the main agent of urinary tract infections

The human intestine is an environment inhabited by many bacteria and other microorganisms collectively known as the gut microbiome, gut microbiota or intestinal flora. In most people, it contributes to wellness. A healthy gut indicates a stronger immune system, improved metabolism, and a healthy brain and heart, among other functions.

Developing new therapies that leverage the host immune system

Yersinia bacteria cause a variety of human and animal diseases, the most notorious being the plague, caused by Yersinia pestis. A relative, Yersinia pseudotuberculosis, causes gastrointestinal illness and is less deadly but naturally infects both mice and humans, making it a useful model for studying its interactions with the immune system.
