Brain parasite makes rodents unafraid of cats, other predators

Cats have the power to control the minds of rodents, through a brain parasite called Toxoplasma gondii. The pathogen exerts a strange mind control on rodents that make them lose their fear of cats and become easier to catch.

Immune system contribution to tumor heterogeneity may influence liver cancer growth

Researchers at Mount Sinai School of Medicine say the immune system might contribute to the tumor heterogeneity seen in liver cancer that can affect the rate of cancer growth.

Overactivation of neuroimmune gene leads to schizophrenia-like changes in mice

Excessive activity of an immune system gene previously linked to schizophrenia reproduces neural and behavioral aspects of the disease in mice, according to a new study publishing on January 14 in the open-access journal PLOS Biology by Ashley Comer and Alberto Cruz-Martín of Boston University and colleagues.

KU Leuven researchers develop new antibacterial strategy that weakens bacteria

Bioscience engineers from KU Leuven in Belgium have developed a new antibacterial strategy that weakens bacteria by preventing them from cooperating. Unlike with antibiotics, there is no resistance to this strategy, because the non-resistant bacteria outnumber resistant ones.

Study reveals how clotting protein and blood platelets promote immune evasion, tumor progression

A new study led by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute reveals how a clotting protein and blood platelets can promote cancer progression and suppress immune responses to cancer.

Biomaterial-based vaccine has potential to completely eliminate AML cells

Acute myeloid leukemia (AML) is a deadly blood cancer that originates in the bone marrow and kills most of its victims within five years. Chemotherapy has been the standard AML treatment for over 40 years, and while it often causes the cancer to go into remission, it rarely completely eliminates the cancerous cells, which then lead to disease recurrence in nearly half of treated patients.

Study shows how cancer-causing genes promote metastasis

Cancer-promoting genes MYC and TWIST1 co-opt immune system cells to enable cancer cells to spread, but blocking a key step in this process can help prevent the disease from developing.

Study provides insights into how viral infection can continue to affect immunity

The strength of the immune system in response to respiratory infections is constantly changing, depending on the history of previous, unrelated infections, according to new research from the Crick.

A New Discovery about MAIT Cells Sheds Light on Early-Phase HIV Infection

Researchers at the Karolinska Institutet, Sweden, have made an important discovery about a poorly understood group of immune cells (mucosa-associated invariant T [MAIT]cells) that could improve understanding of what happens during the initial stages of HIV infection.

Study delineates the dynamic MAIT cell response during acute HIV infection

In a new study published in Nature Communications, researchers at Karolinska Institutet show that MAIT cells (mucosa-associated invariant T cells), part of the human immune system, respond with dynamic activity and reprogramming of gene expression during the initial phase of HIV infection.

Important things you need to know about seasonal flu

Seasonal flu is a serious illness causing approximately 200,000 hospitalizations and 36,000 deaths each year. Federal health officials are reporting that the 2019-2020 flu season could be the worst in decades.

Lymphopenia may hint a higher risk of future illness, death

Lymphopenia, which indicates lower levels of lymphocytes in the blood, has been tied to a higher risk of future illness and death, a new study found.

Researchers provide first robust cell culture model for hepatitis E virus

Even though hepatitis E causes over three million infections and about 70,000 deaths each year, the virus has been little studied as yet.

Mice study offers new insight on irritable bowel syndrome

Sometimes the end of an intestinal infection is just the beginning of more misery. Of those who contract traveler's diarrhea, for example, an unlucky few go on to develop irritable bowel syndrome (IBS), a chronic inflammation of the intestinal tract.

Researchers discover how a new immune system works to protect bacteria from phages

Researchers at University of California San Diego School of Medicine have discovered how a new immune system works to protect bacteria from bacteriophages (phages), viruses that specifically infect bacteria.

Siah2 Gene Control could Help Treat Melanomas More Effectively

To develop improved cancer immunotherapies, it is essential to understand how cancers shut down the natural immune response to foreign antigens. This current study demonstrates how mice lacking the Siah2 gene, fail to develop BRAF-mutation carrying melanoma from the corresponding cells, completely rejecting them. This could help in boosting the anticancer effect of existing specific immune checkpoint inhibitors, such as anti-PD-1 drugs.

Rejuvenating the BCG Vaccine

A new primate study published in the journal Nature in January 2020, reports that the almost century-old BCG vaccine against tuberculosis, may be used differently to achieve better protection against lung tuberculosis. While more work remains to be carried out before the findings can be accepted as the basis for clinical practice, they are extremely promising in the fight against this killer.

Sodium chloride nanoparticles offer potential for cancer therapies with fewer side effects

A new study at the University of Georgia has found a way to attack cancer cells that is potentially less harmful to the patient. Sodium chloride nanoparticles – more commonly known as salt – are toxic to cancer cells and offer the potential for therapies that have fewer negative side effects than current treatments.

Nano-sized copper compounds together with immunotherapy can kill cancer cells

An interdisciplinary team of scientists from KU Leuven, the University of Bremen, the Leibniz Institute of Materials Engineering, and the University of Ioannina has succeeded in killing tumour cells in mice using nano-sized copper compounds together with immunotherapy. After the therapy, the cancer did not return.

Researchers identify new prevention strategy for type 1 diabetes

A protein newly identified as important in type 1 diabetes can delay onset of the disease in diabetic mice, providing a new target for prevention and treatment in people, according to research led by scientists at the U.S. Department of Energy's Pacific Northwest National Laboratory and Indiana University School of Medicine.
