The findings suggest a new approach to clearing infections from AIDS to hepatitis Scientists at The Scripps Research Institute (TSRI) have made a counterintuitive finding that may lead to new ways to clear persistent infection that is the hallmark of such diseases as AIDS, hepatitis B and hepatitis C. The study, reported in the April 12, 2013 issue of the journal Science, focused on the activity of the body's type 1 interferon (IFN-I) proteins. Since its discovery over 50 years ago,...

Autoimmune Diseases Driven By Excessive Intake Of Dietary Salt
2013-03-07 11:01:00

Alan McStravick for redOrbit.com - Your Universe Online Over the previous several years, medical professionals have noted and documented marked increases in the prevalence of autoimmune diseases. An international team of scientists and researchers have come together in an attempt to identify the cause behind the increase in diseases like multiple sclerosis, rheumatoid arthritis, psoriasis and other diseases. What they have learned is that there is a connection between dietary salt intake...

A new report suggests that the concentration of one human cytokine, interleukin 7 (IL-7), in the semen of HIV-1-infected men may be a key determinant of the efficiency of HIV-1 transmission to an uninfected female partner. In their study published February 7 in the Open Access journal PLOS Pathogens, a research group from the Eunice Kennedy-Shriver National Institute of Child Health and Human Development (NICHD) led by Leonid Margolis report that the increased IL-7 concentration in semen...

Helper cells of the immune system can switch to become killer cells in the gut The fate of mature T lymphocytes might be a lot more flexible than previously thought. New research from the RIKEN Center for Allergy and Immunology (RCAI) in Japan and La Jolla Institute for Allergy and Immunology (LIAI) in the USA shows for the first time that mature CD4+ helper T lymphocytes can be re-programed to become killer-like CD8+ T lymphocytes and gain killing functions. The findings are reported...

Earlier therapy enhances restoration of CD4+ T-cell counts Patients who are started on antiretroviral therapy for HIV-1 infection within four months of estimated infection date – and who have higher counts of CD4+ T-cells at the initiation of therapy – demonstrate a stronger recovery of CD4+ T-cell counts than patients in whom therapy is started later, a new study shows. The report, to be published Thursday in The New England Journal of Medicine, is co-authored by physicians...

Scientists from the AIDS Research Institute IrsiCaixa have identified how HIV, the virus that causes AIDS, enters the cells of the immune system enabling it to be dispersed throughout an organism. The new study is published December 18 in the open access journal PLOS Biology. One of the reasons why we do not yet have a cure for HIV infection is that the virus infects cells of the immune system that would normally fight such an infection. The main targets of HIV are white blood cells named...

Cancers arise in the body all the time. Most are nipped in the bud by the immune response, not least by its T cells, which detect telltale molecular markers–or antigens–on cancer cells and destroy them before they grow into tumors. Cancer cells, for their part, evolve constantly to evade such assassination. Those that succeed become full-blown malignancies. Yet, given the right sort of help, the immune system can destroy even these entrenched tumors. In the October 22nd issue...

A new clinical study published in BioMedCentral's open access journal Arthritis Research and Therapy provides preliminary evidence that vitamin D supplementation could be considered an immunomodulatory agent for systemic lupus erythematosus (SLE), a debilitating autoimmune disease characterized not only by skin, joint, neurological and renal symptoms, but also by inflammation of tissue linings in the body. SLE is a T- and B-cell-dependent disease that causes an appearance of...

  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
