Drug Decreases Gut Leakiness Associated With Ulcerative Colitis

Biomedical scientists have found that a drug approved by the FDA to treat rheumatoid arthritis and ulcerative colitis can repair permeability defects in the gut's ... read more

Transition to Exhaustion: Clues for Cancer Immunotherapy

Research on immune cells 'exhausted' by chronic viral infection provides clues on how to refine cancer immunotherapy. The Immunity paper defines a transitional stage in between stem-like ... read more

Dynamics of Crucial Immune System Proteins

Of the many marvels of the human immune system, the processing of antigens by the class I proteins of the major histocompatability complex (MHC-I) is among the most mind-boggling. Exactly how these ... read more

How a Cellular Shuttle Helps HIV-1 Spread in Immune Organs

New insight on how a type of cell facilitates the spread of HIV-1 has just been ... read more

How the Strep Bacterium Hides from the Immune System

A bacterial pathogen that causes strep throat and other illnesses cloaks itself in fragments of red blood cells to evade detection by the host immune system, according to a new study. The researchers ... read more

Consistent Gene Changes in Alzheimer's Disease Across Studies

A comparison of mouse Alzheimer's disease models shows changes in the number of cells and the genes they express remain consistent throughout all stages of the ... read more

Using Artificial Intelligence to Determine Whether Immunotherapy Is Working

Currently, only about 20% of all cancer patients will actually benefit from costly immunotherapy. New research can now determine which ones are in that category, simply by analyzing previously unseen ... read more

Dissecting Connections Between Chronic Stress, Inflammation and Depression

Chronic stress can inflame our brain, destroy the connections between our neurons and result in depression, scientists ... read more

Magnesium Deprivation Stops Pathogen Growth

When pathogens invade the cells, our body combats them using various methods. Researchers have now been able to show how a cellular pump keeps such invading pathogens in check. As the researchers ... read more

Probing the Role of an Inflammation Resolution Sensor in Obesity and Heart Failure

After heart attack injury, ALX/FPR2 is activated by resolvin D1 in immune cells in the spleen and in immune cells at the heart attack site. This speeds expedited resolution of the heart attack ... read more

Creating Viral Targets Can Weaken HIV Vaccination

Vaccination against HIV/SIV can backfire if the vaccine induces the wrong kind of immune response. Scientists have evidence that creating too many soft targets can weaken vaccination that would ... read more

Inflammatory Processes Drive Progression of Alzheimer's and Other Brain Diseases

Inflammation drives the progression of neurodegenerative brain diseases and plays a major role in the accumulation of tau proteins within neurons. The results indicate that inflammatory processes ... read more

A New Pathway to 'Reprogram' Killer Cells

Killer cells of the immune system detect and kill infected cells or cancer cells. Researchers have now discovered that the mechanism by which certain immune cells kill their target cells can also be ... read more

Malaria Discovery Could Lead to Better HIV and Lupus Treatments

A discovery about how the immune system responds to malaria infection could lead to better treatments for hepatitis C, HIV and lupus, say researchers. The research team showed, in laboratory models, ... read more

Mapping the Pathway to Gut Health in HIV and SIV Infections

A new study found that Lactobacillus plantarum bacteria rapidly repaired damaged gut lining (known as leaky gut) in monkeys infected with chronic simian immunodeficiency virus (SIV), an HIV-like ... read more

Technique Identifies T Cells Primed for Certain Allergies or Infections

Researchers can now identify T cells reactive to a particular target from a patient's cells, and to perform high-throughput single-cell RNA sequencing of those ... read more

Evidence in Mice That Childhood Asthma Is Influenced by the Neurotransmitter Dopamine

Neurons that produce the neurotransmitter dopamine communicate with T cells to enhance allergic inflammation in the lungs of young mice but not older mice, researchers report. The findings ... read more

Complex Organ Models Grown in the Lab

Scientists have successfully produced human tissues from stem cells. They have a complexity similar to that of normal tissue and are far superior to previous ... read more

Bacterial Protein Impairs Important Cellular Processes

Researchers have discovered a new function of antibiotic resistant ... read more

Faster, Stronger Rabies Vaccine

Every year, more than 59,000 people around the world die of rabies and there remains no cheap and easy vaccine regimen to prevent the disease in humans. Now, researchers report that adding a specific ... read more
