Blood Immune Cells Cross Protective Barriers to Transform Aging Brains

The brain's immune system has long been thought to exist independently from the rest of the body, complete with its own specialized immune cells and a blood-brain barrier that limits what can travel into the brain.

Newly Identified Protein Prevents T Cells From Destroying Cancer Cells

Researchers at Mayo Clinic have identified a protein that cancer cells use to suppress the body's immune response, a finding that could support the development of new treatments to improve the effectiveness of cancer immunotherapies.

Macrophages Release Brain Protein Beacon Drawing Nerves Into Breast Tumors

New research from the University of Oklahoma demonstrates how an aggressive form of breast cancer co-opts the body's own immune system to attract nerves that fuel tumor growth.

Malaria Infection Causes Permanent Damage to Resident Splenic CD163 Macrophages

Macrophages formed in the bone marrow can only assume the function of embryonal phagocytes, or "scavenger cells," to a certain degree according to a study by the University of Bonn and the Peter Doherty Institute for Infection and Immunity at the University of Melbourne.

Mapping Spatial Genome Architecture Unlocks Hidden Biological Mechanisms Behind Genetic Risk

Much of how genetic risk leads to disease has remained hidden. In many cases, genetic variants linked to disease do not act on nearby genes along the chromosome. Instead, they influence genes located far away along the DNA sequence.

Scientists Identify Lethal Columnaris Fish Disease in Brazil for the First Time

For the first time in Brazil, scientists have identified the presence of bacteria that cause columnaris disease, a serious disease in farmed fish intended for human consumption.

T Cells Identify Dangerous Pathogenic Threats to Keep Bodies Healthy

Your body depends on T cells to stay healthy. These white blood cells act like a neighborhood watch in the body, helping the immune system spot threats such as viruses, bacteria, and cancer cells.

Arginine Supplementation Enhances Immune Defense Against Tumors and Viruses

The amino acid arginine helps to keep the human body humming, most notably by synthesizing proteins that carry out a range of cellular processes.

Dengue Virus Replicates Inside Memory B Cells to Evade Immunity

Researchers at the University of Vermont Robert Larner, M.D. College of Medicine and Upstate Medical University in Syracuse, NY, have discovered that dengue virus can infect and replicate inside memory B cells, immune cells traditionally understood to help protect the body from infection.

Novel Dendritic Cell Vaccine Redirects Viral Memory to Fight Tumors

In a discovery that could redefine the future of cancer immunotherapy, scientists from Celloram Inc., University Hospitals and Case Western Reserve University have developed a novel cancer vaccine platform that transforms the impact of the largest immunological event in modern history

3D Mapping of Tonsil Genetic Structures Unlocks Antibody Optimization

About 2 meters worth of genetic material must fit into the nucleus of each and every one of most of our trillions of cells, coiling and winding to form what looks like a tangled mess.

Molecular Insights Into Fungal Effectors Disabling Host Immune Transcription Factors

Plants defend themselves through a layered innate immune system: pathogen-associated molecular pattern-triggered immunity (PTI) and effector-triggered immunity (ETI), mediated by pattern recognition receptors (PRRs) and nucleotide-binding leucine-rich repeat (NLR) receptors, respectively.

Engineered Probiotic Bacteria Deliver Immune Therapy Directly Into Pancreatic Tumors

Cancer immunotherapies have transformed treatment for many cancers, but pancreatic cancer remains especially difficult to treat. One major reason is that pancreatic tumors often create a "cold" tumor microenvironment, where the tumor prevents immune cells from mounting a strong attack.

Researchers Find New Bacterial Mechanism for Evading Antibiotic Exposure

Antibiotics are a medical marvel, but many microbes are gaining the ability to resist and tolerate these therapeutics.

Tapeworm Makes Ants Live Longer

A tapeworm fundamentally changes the lives of ants: Workers of the species Temnothorax nylanderi that are infected with the tapeworm Anomotaenia brevis live several times longer than their uninfected nestmates.

Basement Membrane Remodeling Drives Melanocyte Dedifferentiation in Vitiligo Skin Lesions

Vitiligo is an autoimmune disease in which the body's immune system attacks and destroys melanocytes, the cells that produce the skin pigment melanin. Once the melanocytes are gone, the skin turns white, leading to the characteristic skin patches of the disease.

Changes in RNA Regulation Enable Bacteria to Enter Antibiotic Tolerance

Antibiotics are a medical marvel, but many microbes are gaining the ability to resist and tolerate these therapeutics. St. Jude Children's Research Hospital scientists have uncovered how S. pneumoniae adapts to antibiotic exposure and immune pressures.

Artificially Recreating C3 Effects Overcomes Resistance in Hard-to-Treat Tumors

An ancient molecule that existed long before the blood circulation system evolved, has been found to support cancer immunotherapy. Researchers at Nagoya University in Japan found that complement C3 protein acts inside tumors to prevent the accumulation of immunosuppressive cells, but only when produced inside the tumor.
