New nanoparticle adjuvant could lead to more powerful vaccines

A common strategy to make vaccines more powerful is to deliver them along with an adjuvant -; a compound that stimulates the immune system to produce a stronger response.

Biologists discover how a pathogenic fungus can bypass the immune system of plants

A team of biologists has identified that the pathogenic fungus Verticillium dahliae, responsible for wilt disease in many crops, secretes an 'effector' molecule to target the microbiome of plants to promote infection.

Anti-idiotype antibodies may explain the long-term effects of COVID-19

With around 256 million cases and more than 5 million deaths worldwide, the COVID-19 pandemic has challenged scientists and those in the medical field. Researchers are working to find effective vaccines and therapies, as well as understand the long-term effects of the infection.

Antibodies play a major role in managing gut mycobiota, says study

According to recent research, antibody protection against harmful forms of fungi in the gut might be disrupted in some patients with Crohn’s disease.

Study analyzes connections between COVID-19 severity and gene expression

Recent research reveals how genetic variations associated with severe cases of COVID-19 impact the immune cells.

Study shows why disruption of the body clock leads to inflammatory diseases

New research from RCSI has demonstrated the significant role that an irregular body clock plays in driving inflammation in the body's immune cells, with implications for the most serious and prevalent diseases in humans.

Researchers expand understanding of how T cells recognize infections or disease

T cells communicate with other cells in the body in search of infections or diseases. This crosstalk relies on specialized receptors known as T cell receptors that recognize foreign molecular fragments from an infection or cancer that are presented for detection by particular molecules called major histocompatibility complex (MHC) or MHC-like.

MIT researchers identify a way to indirectly activate T cells to fight tumors

Under the right circumstances, the body's T cells can detect and destroy cancer cells. However, in most cancer patients, T cells become disarmed once they enter the environment surrounding a tumor.

Cancer cells disarm immune cells by hijacking mitochondria, says research

Researchers utilized the power of nanotechnology to identify a novel means that cancer cells use to disarm their would-be cellular attackers.

New group of molecules that have an antibacterial effect identified

Researchers at Karolinska Institutet, Umeå University, and the University of Bonn have identified a new group of molecules that have an antibacterial effect against many antibiotic-resistant bacteria.

Research demonstrates how diet affects immunity through the gut microbiome

The cliché "you are what you eat" has been used for hundreds of years to illustrate the link between diet and health. Now, an international team of researchers has found the molecular proof of this concept, demonstrating how diet ultimately affects immunity through the gut microbiome.

Covid-19 vaccine-elicited immune cells persist six months after vaccination, study shows

A recent study by Johns Hopkins Medicine researchers provides evidence that CD4+ T lymphocytes — immune system cells also known as helper T cells — produced by people who received either of the two available messenger RNA (mRNA) vaccines for COVID-19 persist six months after vaccination at only slightly reduced levels from two weeks after vaccination and are at significantly higher levels than for those who are unvaccinated.

Study identifies new gene that promotes progression to type 1 diabetes

When the pro-inflammatory pair, a receptor called CCR2 and its ligand CCL-2, get together, it increases the risk of developing type 1 diabetes, scientists report.

Novel therapy induces phagocytosis to treat bacterial pneumonia

Scientists from the National Institutes of Health recently found a therapy that targets host cells instead of bacterial cells in treating bacterial pneumonia.

Researchers test a neoantigen-specific transgenic immune cell therapy for malignant gliomas

Doctors and scientists from the German Cancer Research Center (DKFZ) and from Heidelberg University's Medical Faculty Mannheim have successfully tested a neoantigen-specific transgenic immune cell therapy for malignant brain tumors for the first time using an experimental model in mice.

Cellular enlargement drives a decline in function of stem cells, study suggests

MIT biologists have answered an important biological question: Why do cells control their size? Cells of the same type are strikingly uniform in size, while cell size differs between different cell types. This raises the question of whether cell size is important for cellular physiology.
