Got zinc? New zinc research suggests novel therapeutic targets
Everyone knows that vitamins "from A to zinc" are important for good health. Now, a new research study in the August 2009 print issue of the Journal of Leukocyte Biology suggests that zinc may be pointing the way to new therapeutic targets for fighting infections. view more (2009-07-31)
Protein helps immune cells to divide and conquer
Researchers at the University of California, San Diego School of Medicine have identified a key protein that is required for immune cells called B lymphocytes to divide and replicate themselves. The rapid generation of large numbers of these immune cells is critical to the body's antibody defense mechanism. view more (2009-03-09)
TB -- hiding in plain sight
Current research suggests that Mycobacterium tuberculosis can evade the immune response. view more (2009-05-22)
University of Pennsylvania Researchers Discover "Killer" B Cells; New Link in the Evolution of Immunity
Researchers from the University of Pennsylvania School of Veterinary Medicine have discovered a unique evolutionary link between the immune systems of fish and mammals in the form of a primitive version of B cells, white blood cells of the immune system. view more (2006-09-21)
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...

Vitamin D found to fight placental infection
In a paper available at the online site of the journal Biology of Reproduction, a team of UCLA researchers reports for the first time that vitamin D induces immune responses in placental tissues by stimulating production of the antimicrobial protein cathelicidin. view more (2008-12-02)
Don't be a stranger to yourself
One of the most important tasks of the immune system is to identify what is foreign and what is self. If this distinction fails, then the body's own structures will be attacked, the result of which could be an autoimmune disease such as diabetes mellitus type 1 or multiple sclerosis. view more (2009-03-16)
'Super' enzyme may lead way to better tumor vaccines
A "super" form of the enzyme Akt1 could provide the key to boosting the effect of tumor vaccines by extending the lives of dendritic cells, the immune-system master switches that promote the response of T-cells, which attack tumors, said researchers at Baylor College of Medicine in a report that appears in the "advance online... view more...

Immune exhaustion in HIV infection
As HIV disease progresses in a person infected with the HIV virus, a group of cells in the immune system, the CD8+ T lymphocytes, become "exhausted," losing many of their abilities to kill other cells infected by the virus. view more (2008-05-06)
Flick of a protein switches immune response
A single protein can turn on and off a key component of the immune system by changing partners in an elegant genomic dance, said researchers at the University of Southern California and Harvard Medical School. view more (2006-07-28)
oes peripheral T-lymphocyte subpopulations correlate with hepatitis B virus load?
Hepatitis B virus (HBV) infection is a dynamic process with variable biochemical, virological and histological profiles at different stages of the infection, depending on host and viral factors. Furthermore, this profile may change at a variable pace over time. view more (2009-07-29)
Research uncovers signaling pathways related to brain-immune system links
New research on signaling pathways in immune cells bolsters evidence of connections between the central nervous system and the immune system. view more (2006-05-16)
Previously unknown immune cell may help those with Crohn's and colitis
The tonsils and lymphoid tissues in the intestinal tract that help protect the body from external pathogens are the home base of a rare immune cell newly identified by researchers at Washington University School of Medicine in St. Louis. view more (2008-11-04)
Scientists identify new role for lung epithelial cells in sensing allergens in the air
Researchers at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and at Ghent University in Ghent, Belgium, have identified a new role for certain lung cells in the immune response to airborne allergens. view more (2009-03-31)
Commonly used antidepressants may also affect human immune system
Drugs that treat depression by manipulating the neurotransmitter serotonin in the brain may also affect the user's immune system in ways that are not yet understood, say scientists from Georgetown University Medical Center and a Canadian research institute. view more (2006-01-20)
Penn study finds pro-death proteins required to regulate healthy immune function
Researchers at the University of Pennsylvania School of Medicine have found that proteins known to promote cell death are also necessary for the maturation and proliferation of immune cells. view more (2007-08-13)
Finding protection from tumor growth in unexpected places
Researchers have discovered that an enzyme commonly involved in regulating blood pressure also provides protection from tumor growth when strongly expressed in immune cells. view more (2007-06-06)
Device Protects Transplanted Pancreatic Cells from the Immune System
Scientists at Burnham Institute for Medical Research (Burnham) and the University of California San Diego (UC San Diego) School of Medicine have demonstrated in mice that transplanted pancreatic precursor cells are protected from the immune system when encapsulated in polytetrafluorethylene (PTFE). view more (2009-04-10)
Researchers discover how leukaemia virus spreads through the body
Researchers from Imperial College London, University of Oxford, Kagoshima University (Japan) and University of the Ryukyus (Japan) have discovered the mechanism by which human T-lymphotropic virus type 1 (HTLV-1), the virus which causes adult T-cell leukaemia, spreads through the body. view more (2003-02-12)
Common diabetes drug may 'revolutionize' cancer therapies
Researchers at McGill University and the University of Pennsylvania have discovered that a widely used anti-diabetic drug can boost the immune system and increase the potency of vaccines and cancer treatments. view more (2009-06-04)
