Breast cancer cells outsmart the immune system and thrive

Scientists discovered a new way breast cancer cells dodge the immune system and promote tumor growth, providing a fresh treatment target in the fight against the disease. While comparable mechanisms to avoid the immune system have been identified in...

Fighting the fight for healthy teeth

It is known that teeth can protect themselves, to some extent, from attack by bacteria but that inflammation within a tooth can be damaging and, in extreme cases, lead to abscess or death of the tooth. New research published in BioMed Central's open...

Scientists find the ‘master switch’ for key immune cells in inflammatory...

A new drug target in atherosclerosis: The anaphylatoxin C5a

For decades, doctors have looked at fitness levels, weight, and overall health risk factors for heart disease and stroke. Now, they may soon add a new risk factor to the list: activation of the complement system. The complement system is usually imp...

Tumor cells in blood may signal worse prognosis in head and...

COLUMBUS, Ohio -- A new study suggests that the presence of tumor cells in the circulating blood of patients with squamous cell cancer of the head and neck may predict disease recurrence and reduced survival. An increased number of circulating tumo...

Researchers discover human immune system has emergency backup plan

New research by scientists at the University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences reveals that the immune system has an effective backup plan to protect the body from infection when th...

There’s a new ‘officer’ in the infection control army

Johns Hopkins scientists have identified a previously unrecognized step in the activation of infection-fighting white blood cells, the main immunity troops in the body's war on bacteria, viruses and foreign proteins. "It's as if we knew many of ...

UT Southwestern researchers uncover culprits in life-threatening clotting disorder

DALLAS -- Dec. 3, 2010 -- Thanks to findings by UT Southwestern Medical Center researchers, individuals with a potentially life-threatening condition predisposing them to blood clots, or thrombosis, might someday receive therapy to prevent the...

Blame the environment: Why vaccines may be ineffective for some people

A new discovery may explain why a tuberculosis vaccine is not as effective for some people as anticipated, and potentially explains why other vaccines do not work as well for some as they do for others. In a research report presented in the December...
