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...

Novel method could help advance the fight against persistent 'HIV latency' Scientists at the Gladstone Institutes have gotten us one step closer to understanding and overcoming one of the least-understood mechanisms of HIV infection–by devising a method to precisely track the life cycle of individual cells infected with HIV, the virus that causes AIDS. In a paper being published online today in Lab on a Chip, the laboratory of Gladstone Investigator Leor Weinberger, PhD, announced...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
