Sturdier Immune System May Explain Why Women Live Longer
2013-05-16 09:14:05

redOrbit Staff & Wire Reports - Your Universe Online Women's immune systems age more slowly than men's, which may contribute to their longer average lifespans, according to new research published Wednesday in the journal Immunity & Ageing. The study by Japanese researchers found that levels of key white blood cells responsible for fighting off infections decline faster in ageing men than they do in women. The average life expectancy in the US is 76.0 years for men and 80.9...

Better understanding of cells' development has implications in study of inflammatory diseases Labs around the world, and a core group at Penn, have been studying recently described populations of immune cells called innate lymphoid cells (ILCs). Some researchers liken them to foot soldiers that protect boundary tissues such as the skin, the lining of the lung, and the lining of the gut from microbial onslaught. They also have shown they play a role in inflammatory disease, when the body's...

Portable Counter For White Blood Cells Being Developed

California Institute of Technology White blood cells, or leukocytes, are the immune system's warriors. So when an infection or disease attacks the body, the system typically responds by sending more white blood cells into the fray. This means that checking the number of these cells is a relatively easy way to detect and monitor such conditions. Currently, most white blood cell counts are performed with large-scale equipment in central clinical laboratories. If a physician collects blood...

Researchers Tackle Leukemia With Engineered T-Cell Therapy

Brett Smith for redOrbit.com - Your Universe Online Job training can allow workers to take on new responsibilities and a team of oncologists from Memorial Sloan-Kettering Cancer Center (MSKCC) in New York found that the same thing applies to the body´s immune system. By essentially taking T cells, a type of white blood cell, back to school — the oncologists were able to successfully eradicate a certain type of acute leukemia. Similar previous research has shown promise in...

MEMPHIS, Tenn., March 19, 2013 /PRNewswire-USNewswire/ -- The United States Patent and Trademark Office today awarded St. Jude Children's Research Hospital U.S. patent number 8,399,645 for St. Jude's invention of compositions for genetically modifying human immune cells so they can destroy some of the most common forms of cancer in children and adults. "This groundbreaking invention enables human immune cells to recognize and attack certain cells that cause leukemia and lymphoma, cancers...

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...

Researchers from the RIKEN Research Centre for Allergy and Immunology in Japan report today that they have succeeded for the first time in creating cancer-specific, immune system cells called killer T lymphocytes, from induced pluripotent stem cells (iPS cells). To create these killer cells, the team first had to reprogram T lymphocytes specialized in killing a certain type of cancer, into iPS cells. The iPS cells then generated fully active, cancer-specific T lymphocytes. These lymphocytes...

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...

SEATTLE, Dec. 6, 2012 /PRNewswire/ -- Adaptive Biotechnologies, a leading provider of next-generation sequencing assays for the adaptive immune system, today introduced clonoSEQ, a clinical assay to measure minimal residual disease (MRD) in a range of blood-based cancers that is significantly more sensitive than today's most common tests. clonoSEQ will be available for widespread clinical use by mid-2013. "This new approach of using high throughput sequencing to detect and track...

Certain immune cell receptors are more common than mere chance would dictate. New research shows why Our immune system must be tremendously complex to respond to the unending assault of viruses, bacteria and cancerous cells. One of the mechanisms used by the immune system to cope with the huge variety of possible threats is to randomly combine DNA segments for the production of receptors on lymphocytes — a type of white blood cell. The number of possible receptors that can be...
