Scientists from the University of California, San Diego School of Medicine have identified dendritic antigen-presenting cells in zebrafish, opening the possibility that the tiny fish could become a new model for studying the complexities of the human immune system. The study, reported in the online edition of the Proceedings of the National Academy of Sciences, was headed by David Traver, an associate professor in UCSD's Department of Cellular and Molecular Medicine, with colleagues in UCSD's...

New research published in the Journal of Leukocyte Biology suggests that our innate immune systems are a major contributor to chronic lung diseases like silicosis For the nearly 2 million U.S. workers exposed to silica dust each year, a new discovery may help prevent or treat the development of chronic lung diseases related to this exposure. In the September 2010 issue of the Journal of Leukocyte Biology (http://www.jleukbio.org) scientists from Montana and Texas use mice to show for the...

Researchers at Mount Sinai School of Medicine for the first time have determined that bone marrow cells play a critical role in fighting respiratory viruses, making the bone marrow a potential therapeutic target, especially in people with compromised immune systems. They have found that during infections of the respiratory tract, cells produced by the bone marrow are instructed by proteins to migrate to the lungs to help fight infection. The data are published in the current issue of Cell...

An international team led by scientists at the Sainsbury Laboratory in Norwich, UK, have transferred broad spectrum resistance against some important plant diseases across different plant families. This breakthrough provides a new way to produce crops with sustainable resistance to economically important diseases. Food insecurity is driving the search for ways to increase the amount of food we grow, whilst at the same time reducing unsustainable agricultural inputs. One way to do this is to...

Findings show that ancient 'enemies within' can mimic sepsis Inflammation is at the root of most serious complications occurring after both infection and injury. But while the molecular course of events that leads from microbial infections to the inflammatory condition called sepsis is fairly well understood, it is far less clear how and why physical injury can result in a similarly dangerous inflammatory response. Now a study led by investigators at Beth Israel Deaconess Medical Center...

Scientists have long pondered the seeming contradiction that taking broad-spectrum antibiotics over a long period of time can lead to severe secondary bacterial infections. Now researchers from the University of Pennsylvania School of Medicine may have figured out why. The investigators show that "good" bacteria in the gut keep the immune system primed to more effectively fight infection from invading pathogenic bacteria. Altering the intricate dynamic between resident and foreign bacteria...

When it comes to plants' innate immunity, like many of the dances of life, it takes two to tango. A receptor molecule in the plant pairs up with a specific molecule on the invading bacteria and, presto, the immune system swings into action to defend against the invasion of the disease-causing microbe. Unwrapping some of the mystery from how plants and bacteria communicate in this dance of immunity, scientists at the University of California, Davis, have identified the bacterial signaling...

Unraveling a microbe's multilayer defense mechanisms could lead to effective new treatments for potentially lethal fungal infections in cancer patients and others whose natural immunity is weakened. Although not as well known as bacterial infections, such as MRSA and E.coli, fungal infections such as that caused by the yeast Candida albicans can be more serious and lead to a higher death rate. Using mutant forms of the C. albicans yeast which lacked different parts of the yeast cell wall,...

Infectious disease specialists at UT Southwestern Medical Center have mapped the gene profiles of children with severe Staphylococcus aureus infections, providing crucial insight into how the human immune system is programmed to respond to this pathogen and opening new doors for improved therapeutic interventions.In recent years, much research has focused on understanding precisely what the bacterium S aureus does within the host to disrupt the immune system. Despite considerable advances,...

Group B Streptococcus (GBS), a bacterial pathogen that causes sepsis and meningitis in newborn infants, is able to shut down immune cell function in order to promote its own survival, according to researchers at the University of California, San Diego School of Medicine and the Skaggs School of Pharmacy and Pharmaceutical Sciences. Their study, published online July 13 in the Journal of Experimental Medicine, offers insight into GBS infection "“ information that may lead to new medical...
