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.

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.

Neoadjuvant dual immunotherapy and chemotherapy improve outcomes in patients with resectable NSCLC

In a Phase II trial led by researchers from The University of Texas MD Anderson Cancer Center, adding ipilimumab to a neoadjuvant, or pre-surgical, combination of nivolumab plus platinum-based chemotherapy, resulted in a major pathologic response (MPR) in half of all treated patients with early-stage, resectable non-small cell lung cancer (NSCLC).

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.

Potential approach to improve solid tumor T cell therapy

Researchers at the Perelman School of Medicine at the University of Pennsylvania have been working on a preclinical study that focuses on a new strategy that uses a “one-two punch” to assist T cells in attacking solid tumors.

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.

Study reveals: Coronaviruses that cause common colds boost immune response to COVID-19

During the pandemic, it became clear that children who contracted COVID-19 became less ill than adults. One hypothesis has been that common colds would give children immunity protecting against a severe form of the disease. Researchers at Karolinska Institutet are now able to show that OC43, one of the coronaviruses that cause common colds, boosts the immune response to COVID-19. The study, which is published in PNAS, could give rise to more tailored vaccine programmes for children and adults.

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.

Rice biologists embark on a three-year project to create genetically encoded antibiotics

Synthetic biologists at Rice University are embarking on a three-year project to create "genetically encoded antibiotics," strands of RNA that bacteria will readily copy and share that will selectively kill only disease-causing, pathogenic bacteria.

Gut microbiome may modulate the efficacy of CAR-T cell cancer immunotherapy

Scientists from German Cancer Research Center (DKFZ), together with colleagues from Germany, Israel, and the USA, have found that the gut microbiome may modulate the efficacy of CAR-T cellular immunotherapy CAR-T cells in patients with B cell lymphomas.

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.

Effective backup mechanism ensures efficient antimicrobial responses in humans

In the human body, virus particles are identified by pattern recognition receptors (PRRs) either within or on the cell surface. When a receptor is activated, a signaling cascade is initiated, which results in the production and release of signaling molecules like interferons and cytokines.

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.
