Study uncovers mechanism responsible for pollen-induced allergies

When people are exposed to airborne allergens such as pollens, their immune system responds by sending neutrophils to the airways. Neutrophils are a type of white blood cells that move quickly to a site of injury or invading infection and cause inflammation. Show More Summary

Uncovering the secrets of immune system invaders

Some bacteria and viruses take advantage of the way our immune system works to infect us. Researchers now describe some of the trickery used by mycobacteria.

Gene expression, immune system linked with cancer survival rates

Physicians have long sought a way to accurately predict cancer patients' survival outcomes by looking at biological details of the specific cancers they have. But despite concerted efforts, no such clinical crystal ball exists for the majority of cancers. Show More Summary

T-cell receptor therapy achieves encouraging clinical responses in multiple myeloma

Results from a clinical trial investigating a new T cell receptor therapy that uses a person's own immune system to recognize and destroy cancer cells demonstrated a clinical response in 80 percent of multiple myeloma patients with advanced disease after undergoing autologous stem cell transplants.

The Science of Stress and How Our Emotions Affect Our Susceptibility to Burnout and Disease

last monthHumor / odd : Brain Pickings

How your memories impact your immune system, why moving is one of the most stressful life-events, and what your parents have to do with your predisposition to PTSD.

Do these 3 things to save the AHRQ from extinction

Congress is infected with the budget-cutting bug, and building an effective immune system requires political savvy. Sometimes, it’s simple (“We bomb terrorists” or “We process Social Security checks”), but sometimes an agency struggles. Case in point: AHRQ. A House subcommittee recently voted to eliminate the Agency for Healthcare Research and Quality (AHRQ) as of Oct. […]

Study in mice may identify new ways to treat immune thrombocytopenia

A study in mice may identify new ways to treat immune thrombocytopenia. Immune thrombocytopenia, or ITP, is an autoimmune disease whereby the immune system sends antibodies to attack and destroy the body's platelets--blood cells responsible for controlling bleeding.

Cell division speeds up as part of antibody selection

In response to an infection, the immune system refines its defensive proteins, called antibodies, to better target an invader. New research has revealed two mechanisms that favor the selection of B cells capable of producing antibodies with the highest affinity for that invader.

Unearthing cornerstones in root microbiomes

Scientists looked at roles of three phytohormones, regulatory chemicals produced by a plant's immune system, in controlling the composition of the root microbiome in the model plant Arabidopsis thaliana.

Scripps Florida Scientists Receive $2.8 Million to Develop Innovative Approach to Latent HIV Infection

Scientists at The Scripps Research Institute Florida campus have been awarded a pair of grants totaling nearly $2.8 million to develop a new therapeutic agent to reduce latent levels of HIV that hide from the immune system in infected individuals.

Devon Still Gives Jimmy V Acceptance Speech on Behalf Of His Daughter, Leah (Video)

Leah Still was this year’s recipient of the Jimmy V Perseverance Award.  Unfortunately, she couldn’t make it to the ESPYs to accept the award in person because doctors say her immune system is still too weak to make the trip. Accepting the award for Leah was her father, Cincinnati Bengals defensive tackle Devon Still.  While up […]

HIV uses immune system's own tools to suppress it

A research team has made a significant discovery on how HIV escapes the body's antiviral responses. The team uncovered how an HIV viral protein known as Vpu tricks the immune system by using its own regulatory process to evade the host's first line of defence. The findings pave the way for future HIV prevention or cure strategies.

Magnetic Nanoparticles Could Be Key to Effective Immunotherapy

In recent years, researchers have hotly pursued immunotherapy, a promising form of treatment that relies on harnessing and training the body's own immune system to better fight cancer and infection. Now, results of a study led by Johns...Show More Summary

Why Does PTSD Increase the Risk of Cardiovascular Disease?

A new review article finds that post-traumatic stress disorder (PTSD) leads to overactive nerve activity, dysfunctional immune response and activation of the hormone system that controls blood pressure. These changes can ultimately increase risk of cardiovascular disease.

Matcha Boosts the Immune System

last monthFood & Drink / Tea : T Ching

Sniffling nose, wheezing cough and a cloudy head– we all hate that feeling of being holed up in bed sick all the time! Ever since I started my matcha company four years ago- Zen Green Tea– I’ve noticed that I have not been sick with the flu. I put this … Continue reading ? The post Matcha Boosts the Immune System appeared first on T Ching.

New understanding of genetic susceptibility to infections by Candida, Mycobacterium

The discovery of bi-allelic mutations in RORC in patients with candidiasis and mycobacteriosis revealed the pivotal role of RORC in mucocutaneous immunity to Candida and in systemic immunity to Mycobacterium in humans.

Can We Teach Our Own Immune Cells to Kill Cancer?

One of the most promising areas of research in the fight against cancer is immunotherapy, or stimulating the body's own immune system to destroy cancer. Jason Chesney, M.D., Ph.D., a professor in the University of Louisville Department...Show More Summary

Investigating the Proximate Causes of Defective Antibody Production in the Aged Immune System

2 months agoHealth / Aging : Fight Aging

In the open access paper linked below, researchers outline the proximate cause for one aspect of the characteristic decline in immune function that accompanies aging, in this case the failure to produce sufficient numbers of antibodies in response to the presence of pathogens. Show More Summary

Fishing for New Ways to Stop Parkinson's, a Researcher Makes Big Catches in the Gene Pool

Geneticist Haydeh Payami, Ph.D., is exploring the protective power of coffee, nicotine and NSAIDs -- and the damage caused by the immune system and microbiome. She also finding predictive power in key genetic variations.

Lymphoma: How the tumor escapes the immune response

Natural killer cells of the immune system can fend off malignant lymphoma cells and thus are considered a promising therapeutic approach. However, in the direct vicinity of the tumor they lose their effect. Scientists have now elucidated which mechanisms block the natural killer cells and how this blockade could be lifted.
