The Immune System May Offer Method For Stopping Infection-Caused Inflammation By Targeting Blood Vessels
Treating virulent influenza, sepsis, and other potentially deadly infections long has focused on looking for ways to kill viruses and bacteria. But new research from the University of Utah and Utah State University shows that modulating the body’s own overeager inflammatory response to infection may help save more lives…
Immune Protein Fends Off Exotic Virus
A study published online on February 1 in the Journal of Experimental Medicine shows that antiviral proteins called type I interferons (IFNs) are needed to fend off infection with an exotic mosquito-borne virus called Chikungunya virus…
An Overactive Immune Response Linked To Viral Infections Among Elderly
Researchers at Yale School of Medicine have found that exaggerated responses of the immune system explain why the elderly succumb to viral infections more readily than younger people. Published in the November 19 Cell Host & Microbe, the study bucks the general belief that declining immune responses are to blame for susceptibility to viral infections.
Flu Vaccine Guidance For Patients With Immune Deficiency
While vaccinations for both the seasonal flu and H1N1 are among the best prevention tools available to prevent complications from the flu, should patients with immune deficiency be given the vaccines? In general, there are two different types of vaccines. These are usually referred to as live or killed vaccines. Live vaccines contain live bacteria or a virus that has been modified.
Immune Responses To Flu Vaccine Are Diminished In Lupus Patients
Because morbidity and mortality related to influenza are increased in immunocompromised patients, such as patients with the autoimmune disease systemic lupus erythematosus, it is recommended that patients with SLE get annual flu shots, which are safe and do not increase disease activity. Both antibody and cell-mediated responses are involved in the immune response to influenza; in SLE, antibody responses to the vaccine are diminished, but it is not known if the same effect is seen in cell-mediated responses.
Need For Studies On People With Weakened Immune Systems: Vulnerability To Flu And Response To Vaccination
An article published in the August edition of The Lancet Infectious Diseases reports that additional research is required on the vulnerability to the new H1N1 flu strain of different immunosuppressed populations. The possible effectiveness and side-effects of future vaccines also need to be evaluated.
The Immune Response To Influenza Virus Isn’t ‘All Good’
Complications following infection with the virus that causes flu (influenza virus) are one of the top ten causes of death in the United States. Although infection with influenza virus can directly cause death, many deaths following infection with influenza virus occur because the individual develops pneumonia due to secondary infection with bacteria such as Streptococcus pneumoniae.
New Genetic Immune Disorder In Children Discovered
Your immune system plays an important function in your health — it protects you against viruses, bacteria, and other toxins that can cause disease. In autoinflammatory diseases, however, the immune system goes awry, causing unprovoked and dangerous inflammation. Now, researchers have discovered a new autoinflammatory syndrome, a rare genetic condition that affects children around the time of birth.
USC Researchers Uncover Mechanism That Allows Influenza Virus To Evade The Body¹s Immune Response
California (USC) have identified a critical molecular mechanism that allows the influenza virus to evade the body¹s immune response system. The study will be published in the May 21 issue of the journal Cell Host & Microbe. ³We have found a mechanism that the influenza virus uses to inhibit the body¹s immune response that emphasizes the vital role of a specific protein in defending against viruses,” says Jae Jung, Ph.D.
Computer Simulation Captures Immune Response To Flu
Researchers have successfully tested for the first time a computer simulation of major portions of the body’s immune reaction to influenza type A, with implications for treatment design and preparation ahead of future pandemics, according to work accepted for publication, and posted online, by the Journal of Virology.
