Discovery reveals how protective immune cells protect themselves

Researchers at St. Jude Children's Research Hospital have discovered the mechanism by which immune cells called regulatory T cells keep themselves intact and functional during their demanding task of holding the immune system in check. Show More Summary

Quickies: “Boosted” Immune Systems, Probiotics, and Rebel Virgins

Why binge eating health foods won’t boost your immune system

2 weeks agoNews : The Raw Story

Walk through the aisles of any health food shop and you’ll see pots of echinacea or zinc that promise to “support your immune system” or “maintain its healthy function”. Read new age health blogging sites and you’ll find posts on how drinking hot lemon water or knocking back a shot of wheatgrass...

Medical News Today: New test could detect elusive pathogens in patients at high infection risk

PathoChip - a test that can simultaneously detect a variety of pathogens - was able to identify the cause of a fungal infection in a leukemia patient with a weakened immune system.

The Neurons in Our Gut Help the Immune System Keep Inflammation in Check

The immune system must protect against potential infections, but over-vigilant reactions can cause problems. New research from Rockefeller University shows that neurons in the intestine send signals to immune cells to curb inflammat...

Personalized cancer vaccines

2 weeks agoHumor / odd : Kottke.org

Neoantigen vaccines use the DNA from a cancer patient's own tumor to, hopefully, eradicate the cancer. For some 50 years, cancer biologists have tried to incite the immune system to attack cancer by targeting molecules that commonly stud the surfaces of malignant cells. Show More Summary

The neurons in our gut help the immune system keep inflammation in check

The immune system exercises constant vigilance to protect the body from external threats--including what we eat and drink. A careful balancing act plays out as digested food travels through the intestine. Immune cells must remain alert...Show More Summary

Computational Analysis of Breast Cancer Finds That Many Cell Types Correlate with Patient Survival and Genomic Features

A study by researchers at Norris Cotton Cancer Center has shown that a very sensitive computational method can be used to reveal the human immune system's effect on cancer. The Dartmouth study was the first to perform an in-depth computational examination of how immune activity translates to prognosis in breast cancer.

MHC class II molecules on graft endothelium promote acute rejection

A limitation of organ transplant is acute rejection of the graft by the host immune system. Graft rejection is mediated by the development of CD8 + cytotoxic T cells that target donor MHC class I molecules, and in animal models, these cells have been shown to develop in secondary lymphoid organs.

Immune system maintains a memory of past infections by priming genes for future encounters

Our ability to fight off recurrent infections, such as colds or flu, may lie in the 'immunological memory' found in a newly discovered class of gene regulatory elements, according to research from the University of Birmingham, supported...Show More Summary

Researchers Reveal Structure of Protein Complex That Plays Key Role in Modulating Immune System

Search for new inflammatory disease drugs may be aided by detailed structure of distinct ubiquitin ligase complex

Structure of protein complex that plays key role in modulating immune system revealed

La Jolla, Calif., January 20, 2016 -- Scientists at Sanford Burnham Prebys Medical Discovery Institute (SBP) have solved the atomic structure of a unique ubiquitin ligase complex. Ubiquitin is best known for its role in protein degradation,...Show More Summary

Can you die from Alzheimer's disease?

A person does not die directly from Alzheimer's disease. Over time, and as Alzheimer's progresses, the body's immune system weakens, increasing susceptibility to infection and other causes of death related to the elderly.Typical complications...Show More Summary

Disrupting cell's supply chain freezes cancer virus

The cancer-causing Epstein-Barr virus tricks B-Cells of the human immune system into rapid cell division. To satisfy demand for more building parts, host cells will chew up their insides to free up more amino acids, fats and nucleotides. Show More Summary

Disrupting cell's supply chain freezes cancer virus

DURHAM, N.C. -- When the cancer-causing Epstein-Barr virus moves into a B-cell of the human immune system, it tricks the cell into rapidly making more copies of itself, each of which will carry the virus. To satisfy a sudden increase...Show More Summary

Immune 1-2-3 punch against parasites reveals potentially ancient cell death pathway

The immune system's killer cells deliver a tightly controlled, 3-phase knockout punch that kills intracellular parasites through a novel pathway that an international team led by researchers from the Program in Cellular and Molecular...Show More Summary

Easier diagnosis for fungal infection of the lungs

A new clinical imaging method may enable doctors to tackle one of the main killers of patients with weakened immune systems sooner and more effectively.

Finding the needle in a microbial haystack

PHILADELPHIA - Patients who are undergoing treatment for diseases such as cancer often face the added challenge of a compromised immune system, which can be a toll both of their condition and the drugs used to treat it, leaving them vulnerable to various opportunistic infections. Show More Summary

Important Regulator of Immune System Decoded

Plasma cells play a key role in our immune system. Now scientists at the Research Institute of Molecular Pathology (IMP) in Vienna, Austria, and at the Walter and Eliza Hall Institute (WEHI) in Melbourne, Australia, succeeded in characterizing a central regulator of plasma cell function.
