IL-21 receptor plays an essential role in the Th2 immune response
June 16, 2006Cytokines in chronic diseases
During the immune response cells known as Th2 cells express a variety of cytokines (e.g. interleukin-4, -5, and -13), many of which stimulate B cells to proliferate and produce antibodies. This reaction is known as a Th2 immune response. In a study appearing online on June 15 in advance of print publication in the July issue of the Journal of Clinical Investigation, Thomas Wynn and colleagues from the National Institute of Allergy and Infectious Diseases in Maryland, investigated the role of a newly discovered cytokine receptor, the IL-21 receptor (IL-21R), in the Th2 response. To do this they infected mice that lacked IL-21R with 2 parasites known to induce the Th2 response: Schistosoma mansoni and Nippostrongylus brasiliensis. They found that inflammation and liver fibrosis were significantly reduced in infected IL-21R-deficient mice compared to normal infected mice. The authors determined that IL-21R has an essential role in the development of pathogen-induced Th2 immune responses and is an important amplifier of alternative macrophage activation. These findings may have relevance for the understanding and treatment of both inflammatory and chronic fibrotic diseases.

Although morphine has been the gold-standard treatment for postoperative and chronic cancer pain for two centuries, a growing body of evidence is showing that opiate-based painkillers can stimulate the growth and spread of cancer cells.
New culprit for viral infections among elderly -- an overactive immune response
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.
Thoughtful words help couples stay fighting fit
Couples who bring thoughtful words to a fight release lower amounts of stress-related proteins, suggesting that rational communication between partners can ease the impact of marital conflict on the immune system.
Researchers mobilizing global resources to test new treatments for severe H1N1 infection
An important, ground-breaking initiative is unfolding in the global critical care community in response to the H1N1 pandemic.
People with less education could be more susceptible to the flu
People who did not earn a high school diploma could be more likely to get H1N1 and the vaccine might be less effective in them compared to those who earned a diploma, new research shows.
Scientists successfully reprogram blood cells
Researchers have transplanted genetically modified hematopoietic stem cells into mice so that their developing red blood cells produce a critical lysosomal enzyme -preventing or reducing organ and central nervous system damage from the often-fatal genetic disorder Hurler's syndrome.
UCI embryonic stem cell therapy restores walking ability in rats with neck injuries
The first human embryonic stem cell treatment approved by the FDA for human testing has been shown to restore limb function in rats with neck spinal cord injuries - a finding that could expand the clinical trial to include people with cervical damage.
Hundreds of genes distinguish patients likely to survive advanced melanoma
Although the chances of surviving advanced melanoma aren't very good with current therapies, some patients can live for years with cancer that has spread beyond the skin to other organs.
New Notre Dame study provides insights into the molecular basis of tumor cell behavior
A new study by a team of researchers led by Crislyn D'Souza-Schorey, associate professor of biological sciences at the University of Notre Dame, sheds light on the molecular basis by which tumor cells modulate their surroundings to favor cancer progression.
New Synthetic Molecules Trigger Immune Response to HIV and Prostate Cancer
Researchers at Yale University have developed synthetic molecules capable of enhancing the body's immune response to HIV and HIV-infected cells, as well as to prostate cancer cells. Their findings, published online in the Journal of the American Chemical Society, could lead to novel therapeutic approaches for these diseases.

Mechanisms of Lymphocyte Activation and Immune Regulation XI: B Cell Biology (Advances in Experimental Medicine and Biology) (v. 11) by Sudhir Gupta (Editor), Frederick W. Alt (Editor), Max D. Cooper (Editor), Fritz Melchers (Editor), Klaus Rajewsky (Editor) In recent years, major developments have been made in understanding various genetic and epigenetic regulatory processes that are critical for the generation of B cell repertoires. These include the role of chromatin regulation and nuclear organization in understating the IgH gene regulation. A role and mechanism of DNA repair proteins in somatic hypermutation has been elucidated. Genetic mutation studies have been instrumental in providing insight into some of the mechanisms involved in targeting CSR to various switch DNA regions located upstream of C region genes, especially a role of AID motifs, transcription, and R-loops. Recent studies support a dominant role of receptor editing in central B cell tolerance and signaling pathways that regulate receptor editing in self-reactive and... |

Understanding Hereditary Angioedema: A Mysterious Out-of-Control Immune Response Part of the award winning public television series Healthy Body/Healthy Mind. Its called Hereditary Angioedema and its so rare popular television shows have used it as one of their mystery diagnoses. But for the people who suffer with this condition the drama associated with an episode of hereditary angioedema is anything but entertaining. It can be harrowing and horrifying because a person's face or knees or other parts of the body that once looked normal suddenly takes on grotesque proportions due to an unusual amount of swelling. This condition baffled scientists and researchers for many years but today there are new treatments for hereditary angioedema that are helping people with this condition live healthy normal lives. In this program we'll hear what the experts have discovered... |

Chlamydia pneumoniae immunology: Innate Immune Responses induced by Chlamydia pneumoniae infection by Vjera Magdalenic (Author) Chlamydiae are common pathogens that cause a number of serious but preventable diseases in both humans and animals. In the recent years, Chlamydia pneumoniae has emerged as a major cause of human respiratory disease and more importantly, it has been linked to the establishment and exacerbation of serious chronic diseases including atherosclerosis and ischaemic heart disease, multiple sclerosis and reactive arthritis. There has been a lot of research into host responses to chlamydial infections and the development of immunopathology; but considerable gaps in our knowledge remain. The work described here aimed to analyse the early innate immune responses in the lung following C. pneumoniae infections with a view to better understanding host-pathogen interactions and the... |
