HIV infects specific cells of the immune system, called CD4 cells or T-cells. Over time, HIV can destroy so many of these cells that the body cannot fight off infections and disease. When this happens, HIV infection leads to Acquired Immunodeficiency Syndrome (AIDS) which is the final stage of HIV infection. There is no cure […]
Did you know there are health IT tools that can help you and your providers track your vaccinations? They are known as Immunization information systems. These systems are confidential, population-based, computerized systems that record all vaccination doses administered by participating providers to people within a given area. Show More Summary
If approved by the Food and Drug Administration, the drug would be the first in a promising new class designed to help the body's own immune system fend off cancer by blocking a protein known as Programmed Death receptor (PD-1), or a related target known as PD-L1, used by tumors to evade disease-fighting cells.

University of Adelaide researchers have discovered that the immune system is defective in people suffering from irritable bowel syndrome, which is a major reason why sufferers have ongoing issues with pain. The research – the first of its kind in the world – could also help to explain why some painkillers may not offer satisfactory relief to sufferers. read more
Necessary for blood clotting, vitamin K does not transfer through the placenta during birth. This leaves babies with very little of the nutrient in their systems when they are born, putting them at risk for haemorrhagic disease of the newborn (HDN) at birth. Show More Summary
A single factor can reset the immune system of mice to a state likely similar to what it was 500 million years ago, when the first vertebrates emerged. The model, researchers report, could provide an explanation of how the immune system had developed in the course of evolution.
A new study aims to help scientists understand how different antibiotics affect bacteria that play a positive role in promoting a healthy immune system. “This is the first step to understanding which bacteria are absolutely necessary to develop a healthy immune system later in life,” says the lead researcher.

The drug, which suppresses immune system activity, showed significant results for several participants but did not work for everyone in the small test group.
A mutant form of a bacterium that lives in soil and thrives in low-oxygen environments appears to be a precise and aggressive killer of malignant tumors as well as an energetic activator of the body's immune system, according to new research.
Albert Trummer cares about your immune system. Mad-genius bartender Albert Trummer, whose proprietary and flaming cocktails at Apothéke burned perhaps a little too brightly for New York City's nightlife scene back in aughts, has resurfaced...Show More Summary
A control signal for the immune system has been discovered that could help treat autoimmune diseases and cancer. "We discovered a mechanism responsible for stabilizing the cells that maintain immune system balance," says the senior author. Show More Summary
Bacteria's ability to destroy viruses has long puzzled scientists, but researchers at the Johns Hopkins Bloomberg School of Public Health say they now have a clear picture of the bacterial immune system and say its unique shape is likely why bacteria can so quickly recognize and destroy their assailants.
LA JOLLA—When faced with pathogens, the immune system summons a swarm of cells made up of soldiers and peacekeepers. The peacekeeping cells tell the soldier cells to halt fighting when invaders are cleared. Without this cease-fire signal,...Show More Summary
Although HIV can now be effectively suppressed using anti-retroviral drugs, it still comes surging back the moment the flow of drugs is stopped. Latent reservoirs of HIV-infected cells, invisible to the body's immune system and unreachable by pharmaceuticals, ensure that the infection will rebound after therapy is terminated. read more
Like other herpesviruses, cytomegalovirus (CMV) cannot be effectively naturally cleared from the body as it has evolved the means to hide from the immune system. It is harmless for most people in the short term, but over the long term it causes ever more of the limited supply of immune cells to become uselessly devoted to fighting it. Show More Summary
The fungal infection invasive aspergillosis (IA) can be life threatening, especially in patients whose immune systems are weakened by chemotherapy or immunosuppressive drugs. Despite the critical need for early detection, IA remains difficult to diagnose. Show More Summary
Children with high everyday levels of a protein released into the blood in response to infection are at greater risk of developing depression and psychosis in adulthood, according to new research which suggests a role for the immuneShow More Summary
Boston, MA – Following a tissue graft transplant—such as that of the face, hand, arm or leg—it is standard for doctors to immediately give transplant recipients immunosuppressant drugs to prevent their body's immune system from rejecting and attacking the new body part. Show More Summary
