HIV-infected people who carry a gene for a specific protein face a 20-fold greater risk of contracting cryptococcal disease, according to a study published in mBio®, the online open-access journal of the American Society for Microbiology. Cryptococcus neoformans is the most common cause of fungal meningitis among HIV-infected individuals. While the disease is a risk for everyone with HIV who has a very low level of CD4+ T cells, researchers have discovered that those with the gene for the...

Implications for development of immune system and allergies, say researchers The range of helpful bacteria in the guts of infants delivered by caesarean section, during their first two years of life, is narrower than that of infants delivered vaginally, indicates a small study published online in the journal Gut. This has implications for the development of the immune system, say the researchers, particularly as the C-section infants had lower levels of the major group of gut bacteria...

Biologists at the California Institute of Technology (Caltech) have worked out the details of a mechanism that leads undifferentiated blood stem cells to become macrophages—immune cells that attack bacteria and other foreign pathogens. The process involves an unexpected cycle in which cell division slows, leading to an increased accumulation of a particular regulatory protein that in turn slows cell division further. The finding provides new insight into how stem cells are...

1. Scientists at A*STAR’s Singapore Immunology Network (SIgN) have discovered a new class of white blood cells in human lung and gut tissues that play a critical role as the first line of defense against harmful fungal and bacterial infections. This research will have significant impact on the design of vaccines and targeted immunotherapies for diseases caused by infectious microbes such as the hospital-acquired pneumonia. 2. The scientists also showed for the first time...

Scientists at Emory Vaccine Center have shown that an immune regulatory molecule called IL-21 is needed for long-lasting antibody responses in mice against viral infections. The results are published in the Journal of Virology. "Our findings highlight how IL-21 could be important in the development of antiviral vaccines," says research associate Ata Ur Rasheed Mohammed, PhD, the first author of the paper. The senior author is Rafi Ahmed, PhD, director of the Emory Vaccine Center and a...

Asthma Patients May Breathe More Easily Thanks To Game Changing Drug
2013-05-22 15:08:56

Lee Rannals for redOrbit.com — Your Universe Online Researchers said on Tuesday that a new type of asthma drug could be a potential game changer for patients with moderate to severe respiratory disease. The injectable drug, known as dupilumad, slashed asthmatic episodes by 87 percent in a mid-stage trial of 104 patients. The team wrote about the latest trial's results in the New England Journal of Medicine (NEJM). "Asthma that is difficult to treat is increasingly recognized as...

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...
