Thale cress goes on the defensive
Thale cress has a complicated defence technique against insects and microorganisms that use the plant as a source of food. The plant hormone jasmonic acid plays a major role during the immune response against insects and pathogens. Dutch researcher Vivian van Oosten has demonstrated that this does not necessarily lead to the control of the same genes during the various interactions. (2007-05-14)

New Concepts Proposed To Investigate Drug Reactions

How the body stops the type 2 innate immune response from triggering allergic disease
Researchers from the RIKEN Center for Integrative Medical Sciences (IMS) in Japan have shown how the body suppresses the activation of the long-lived cells involved in the anti-parasitic type 2 innate immune response after infection, preventing the response for continuing when it is no longer needed and can trigger allergic responses. (2015-11-23)

IL-21 receptor plays an essential role in the Th2 immune response
During the immune response immune cells express a variety of cytokines that stimulate B cells to proliferate and produce antibodies. In a study in the June 15 version of the Journal of Clinical Investigation, researchers from the National Institute of Allergy and Infectious Diseases investigated the role of a newly discovered cytokine receptor, the IL-21 receptor, in the immune response. These findings may impact the understanding and treatment of inflammatory and chronic fibrotic diseases. (2006-06-15)

Zika-related nerve damage caused by immune response to the virus
The immune system's response to the Zika virus, rather than the virus itself, may be responsible for nerve-related complications of infection, according to a Yale study. This insight could lead to new ways of treating patients with Zika-related complications, such as Guillain-Barré syndrome, the researchers said. (2017-11-20)

Elderly immune system needs a boost
Elderly cancer patients need a combination of treatments tailor-made to their specific needs to successfully combat the disease. Dr. Joseph Lustgarten, from the Mayo Clinic College of Medicine in the US, reviews the effects of aging on the immune system and strategies used to activate a stronger antitumor immune response in the elderly, including genetic modifications in animal models. His findings have just been published in the latest issue of Springer's journal Cancer Immunology, Immunotherapy. (2009-10-08)

Individuals vary their immune response according to age, sex and the costs
Individual zebra finches vary their immune response to balance the costs, depending on sex, age and the environment. When changing from nest-bound juveniles to adults, female immune responses matured slowly while males who were molting into colorful plumage showed dramatic variation. Adult males showed little variation. When females laid eggs with high-quality resources, immune responses similar to nonbreeding females and for males. However, when laying eggs on reduced resources, females reduced their immune response. (2008-09-10)

Circadian clock governs highs and lows of immune response
It's been said that timing is everything, and that may be particularly true when it comes to the ability to fight off disease. New research published by Cell Press in the February issue of the journal Immunity shows that the success of host immune defense depends in part on an organism's (2012-02-16)

Protein proves influential to healthy immune system
Researchers have discovered that the protein Myb plays a vital role in keeping our immune system healthy, and preventing the development of immune and inflammatory diseases. Preclinical findings revealed that Myb gives immune cells called regulatory T (Treg) cells the 'authority' to control the strength of the immune response depending on the level of 'threat,' from minor infections to aggressive diseases. (2017-03-13)

Chronic stress may influence effectiveness of vaccines
A new Carnegie Mellon University study shows that chronic stress can have an impact on the overall effectiveness of immunizations designed to protect against infectious diseases such as flu, hepatitis and pneumonia according to a critical review of published studies.

How cellular structure orchestrates immunologic memory
With every infection or vaccination, memory cells form that the body uses to remember the pathogen. This has been known for decades -- but the structure of this cellular immunologic memory has previously proven impossible to pin down. Researchers from the University of Basel and University Hospital Basel have now identified a microanatomical region in memory cells that enables them to work rapidly in the first few hours of an immune response, as they report in the journal Immunity. (2018-03-08)

Fecal transplants from young to aged mice can stimulate the gut microbiome and revive the gut immune system, a study by immunologists at the Babraham Institute, Cambridge, UK, has shown. The study, published in Nature Communications, suggest that the gut microbiome could be a target for the treatment of a range of age-associated symptoms to facilitate healthy ageing. (2019-06-04)

A braking system for immune responses
For the first time, researchers have identified a receptor on human cells that specifically recognizes crystals. It is found on immune cells and binds uric acid crystals, which trigger gout but also control immune responses. The team, led by researchers from Technische Universitaet Muenchen's Klinikum rechts der Isar hospital have published their findings in the Immunity journal. (2014-03-20)

PNAS: From HIV to cancer, IL-37 regulates immune system
A University of Colorado Cancer Center study published in this month's Proceedings of the National Academy of Sciences describes the activity of a recently discovered communication molecule of the body's immune system, Interleukin 37 or IL-37. It has been known to limit inflammation and the current study reports its activity in the adaptive immune system: IL-37 inhibits the ability of the immune system to recognize and target new antigens. (2014-11-03)

Bats save energy by reducing energetically costly immune functions during annual migration
A team of scientists led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) investigated whether and how the immune response changes between pre-migration and migration seasons in the Nathusius pipistrelle bat. They confirmed that migratory bats favour the energetically ''cheaper'' non-cellular (humoral) immunity during an immune challenge and selectively suppress cellular immune responses. Thereby, bats save energy much needed for their annual migration. (2020-10-15)

Huntington's disease: catching it early
Scientists in England report that signs of Huntington's disease appear in the blood almost 15 years before the patients develop symptoms of brain damage. This study will be published online July 14 in the Journal of Experimental Medicine. (2008-07-14)

Survival gene may be key to controlling HIV and hepatitis
A newly discovered gene that is essential for embryo survival could also hold the key to treating and potentially controlling chronic infections such as HIV, hepatitis and tuberculosis. The gene, called Arih2, is fundamental to the function of the immune system -- making critical decisions about whether to switch on the immune response to an infection. (2012-11-25)

Researchers uncover how Ebola virus disables immune response
The Ebola outbreak in West Africa has brought a lot of attention to the deadly virus. According to the World Health Organization, up to 90 percent of those infected with Ebola die from the virus. Now, researchers publishing Aug. 13 in the journal Cell Host & Microbe reveal how Ebola blocks and disables the body's natural immune response. Understanding how Ebola disarms immune defenses will be crucial in the development of new treatments for the disease. (2014-08-13)
