Identifying the underlying causes of rare genetic immune disorders

The activated PI3K Delta syndrome 2 (APDS2) is a rare genetic disease that is caused by cellular anomalies, according to experts from the Garvan Institute of Medical Research.

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.

New study pinpoints key source of T cell "exhaustion"

Custom-made to attack cancer cells, CAR T-cell therapies have opened a new era in the treatment of human cancers, particularly, in hematologic malignancies.

T cell-driven changes in the gut may affect brain function associated with depression

In experiments with mice and humans, a team led by Johns Hopkins Medicine researchers says it has identified a particular intestinal immune cell that impacts the gut microbiome, which in turn may affect brain functions linked to stress-induced disorders such as depression.

Blunted inflammatory response could make obese patients more susceptible to severe COVID-19

Individuals who are obese may be more susceptible to severe COVID-19 because of a poorer inflammatory immune response, say Cambridge scientists.

Macrophages likely to be a potential target for ER+ breast cancer

Most immunotherapies that aim to increase T cell activity are ineffective in treating estrogen receptor-positive (ER+) breast cancer. A new study of invasive ER+ breast cancers led by researchers at the University of Pittsburgh School of Medicine implies that targeting a different type of immune cell called macrophages may be a more effective approach.

Study discovers the ability of certain blood immune cells to proliferate

The ability of a cell to divide, to proliferate, is essential for life and gives rise to the formation of complex organisms from a single cell.

New antibody "cocktail" may help counter the Lassa virus

The finding, made with the use of the Advanced Photon Source, shows a new way to exploit monoclonal antibodies to subvert the "shield" of the virus, potentially paving the way for new therapies.

Immune landscape in invasive ER+ breast cancers reveals a macrophage-driven microenvironment

Most immunotherapies, which aim to boost T cell activity, work poorly in treating estrogen receptor-positive (ER+) breast cancer.

Common commensal gut bacterium uses phase separation of Rho factor to thrive in the mammalian gut

The common commensal gut bacterium Bacteroides thetaiotaomicron uses phase separation of the transcription termination factor Rho to colonize and thrive in the mammalian gut, according to a new study in mice.

Highlighting a potential sex‐specific precision immunotherapy strategy

Immunotherapy is an effective form of treatment for various types of cancer. However, its effect on pancreatic cancer is restricted and varies between men and women. Karolinska Institutet scientists have observed a possible explanation for this gender difference.

High doses of sucralose limit T cell proliferation and differentiation

Scientists at the Francis Crick Institute have found that high consumption of a common artificial sweetener, sucralose, lowers activation of T-cells, an important component of the immune system, in mice.

New therapeutic approaches to treat autoimmune diseases using a metabolite

Researchers have revealed the modulatory effect of the anti-inflammatory metabolite itaconate on T helper and T regulatory cells, which may lead to new therapeutic approaches to treating some autoimmune diseases.

High correlation between the product of a gene in the majority of cancers

The product of a gene expressed in most cancers, including the most prevalent type of head and neck cancer, has been linked to elevated levels of white blood cells that produce antibodies inside tumors, according to researchers at the University of California San Diego School of Medicine and UC San Diego Moores Cancer Center.

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.

New framework to identify possible viral hazards to human health

The majority of what scientists know about viruses in animals comes from the list of nucleotides that constitute their genomic sequence, which, although useful, provides relatively few signals about a virus’ propensity to infect people.

New perspective on how immune cells perceive viruses and other threats

A textbook chapter on the immune system may need to be revised as a result of a new study from Aarhus University.

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.

Understanding the relationship between gut microbiome and CAR T-cell therapy response

Microorganisms live in or on almost every part of the human body and play an important role in the regulation of normal human processes. As a result, changes in the number or type of microorganisms, also known as the microbiome, can contribute to disease and altered responses to therapy, including cancer treatment.
