Bacterium manipulates the human defence system: The Borrelia bacterium is a master of disguise
Borrelia bacteria are capable of masking themselves in the human body and deceiving the immune defence system. In this way they can hide in the human organism even for periods of years. In their recent studies Professor Seppo Meri and his team have managed to trace the evasive movements of the Borrelia bacterium in the body. Their work is part of... view more... (2005-05-20)
Jefferson scientists find protein helps pancreatic cancer cells evade immune system and spread
A protein that helps prevent a woman's body from rejecting a fetus may also play an important role in enabling pancreatic cancer cells to evade detection by the immune system, allowing them to spread in the body. view more (2008-01-11)
Scientists stop autoimmune disease without shutting off immune system
Skin is our first line of defense against infection. But people with a rare, life-threatening autoimmune disease called pemphigus vulgaris lack that protection because their immune system attacks the proteins that hold skin cells together. view more (2006-08-23)
'First Aid' for Brain Cells Comes From Blood
In acute ischemic stroke, the blood supply to the brain is restricted. Initially, brain cells die from lack of oxygen. view more (2009-04-17)
TB -- hiding in plain sight
Current research suggests that Mycobacterium tuberculosis can evade the immune response. view more (2009-05-22)
Vaccine to cope with viral diversity in HIV
The ability of HIV-1 to develop high levels of genetic diversity and acquire mutations to escape immune pressures contributes to our difficulties in producing a vaccine. view more (2007-04-27)
Plant protein 'doorkeepers' block invading microbes, study finds
A group of plant proteins that "shut the door" on bacteria that would otherwise infect the plant's leaves has been identified for the first time by a team of researchers in Denmark, at the University of California, Davis, and at UC Berkeley. view more (2009-06-29)
Different type of colon cancer vaccine reduces disease spread, Jefferson scientists show
Taking advantage of the fact that the intestines have a separate immune system from the rest of the body, scientists at the Kimmel Cancer Center at Jefferson in Philadelphia have found a way to immunize mice against the development of metastatic disease. view more (2008-06-25)
Scientists find a key to immune system's ability to remember
Its ability to accurately catalog and recall long past encounters with viruses, bacteria and other pathogens is why we only get the measles or chicken pox once, and is why exposure to deactivated virus particles in vaccines confers protection from disease. view more (2006-10-24)
Bypassing the insulin highway
An immune cell known as a neutrophil releases a protein that can suppress glucose production in the liver -without targeting insulin, researchers have found. view more (2008-04-28)
Immune cells contribute to the development of Parkinson's disease
Parkinson disease is a neurodegenerative disorder that impairs movement, balance, speech, and other functions. It is characterized by the loss of nerves in the brain that produce a substance known as dopamine. view more (2008-12-23)
St. Jude finds molecule that could improve cancer vaccines and therapy for other diseases
Investigators at St. Jude Children's Research Hospital have discovered a new signaling molecule that prevents immune responses from running amok and damaging the body. view more (2007-11-26)
HIV handicaps itself to escape immune system pressure
People with the ability to stave off AIDS for years after initial infection by HIV have been called "long-term non-progressors" or "elite controllers." view more (2009-04-16)
A functional immune system can be derived from embryonic stem cells, preliminary study finds
A new study demonstrates for the first time that embryonic stem cells can be used to create functional immune system blood cells, a finding which is an important step in the utilization of embryonic stem cells as an alternative source of cells for bone marrow transplantation. view more (2008-02-13)
Immunologists identify biochemical signals that help immune cells remember how to fight infection
Immunology researchers at UT Southwestern Medical Center have discovered how two biochemical signals play unique roles in promoting the development of a group of immune cells employed as tactical assassins. view more (2009-05-29)
Study identifies key player in the body's immune response to chronic stress
Osteopontin (OPN), a protein molecule involved in many different cellular processes, plays a significant role in immune deficiency and organ atrophy following chronic physiological stress, resulting in increased susceptibility to illness. view more (2007-09-04)
Discovery in the evolution of the immune system absorbing cells
Led by Dr J Oriol Sunyer, of the Faculty of Veterinary Medicine at the University of Pennsylvania, and formed by researchers from Philadelphia, St Louis and Idaho (USA) and by Dr Lluís Tort of the Universitat Autònoma de Barcelona, the group has been able to show that B cells in fish as well as in amphibians are capable of strong phagocytosis... view more...

A key antibody, IgG, links cells' capture and disposal of germs
Scientists have found a new task managed by the antibody that's the workhorse of the human immune system: Inside cells, Immunoglobulin G (IgG) helps bring together the phagosomes that corral invading pathogens and the potent lysosomes that eventually kill off the germs. view more (2006-11-14)
Phase II study of therapeutic vaccine shows efficacy in patients with metastatic colorectal cancer
A therapeutic cancer vaccine has shown effectiveness when given alongside chemotherapy to patients with metastatic colorectal cancer in a phase II trial, according to researchers at Oxford BioMedica (UK) Ltd. view more (2007-08-02)
