white blood cells
How much can a cell uptake?
Immunological research at the University of Haifa, Israel, has made a new breakthrough, revealing a critical component in the “decision-making” process of white blood cells that play a role in the healing process from bacterial inflammation. “Th…
For first time, scientists show an HIV vaccine impacts the genetic makeup of the virus
An AIDS vaccine tested in people, but found to be ineffective, influenced the genetic makeup of the virus that slipped past. The findings suggest new ideas for developing HIV vaccines.
The results were published Feb. 27 in Nature Medicine.

How long do stem cells live?
LA JOLLA, Calif., March 1, 2011 — When patients receive a bone marrow transplant, they are getting a new population of hematopoietic stem cells. Fresh stem cells are needed when a patient is low on red blood cells, as in anemia, or white blood cel…
Study finds close linkage between a rare, deadly lung condition and blood cell abnormalities
WASHINGTON, February 28, 2011) — Results from a study published in Blood, the Journal of the American Society of Hematology reveal a close relationship between pulmonary arterial hypertension (PAH) — exceedingly high blood pressure in the arterie…
Wayne State University researchers publish results settling multiple sclerosis debate
In an effort to develop therapeutic remedies for multiple sclerosis, scientists debate two possible interventional approaches – but they’re on opposite sides of the spectrum. Researchers at Wayne State University’s School of Medicine, however, have …
Scientists bioengineer a protein to fight leukemia
LOS ANGELES (February 18, 2011) — Scientists at the Children’s Center for Cancer and Blood Diseases and The Saban Research Institute of Children’s Hospital Los Angeles today announced a breakthrough discovery in understanding how the body figh…
Nanoparticles may enhance circulating tumor cell detection
Tiny gold particles can help doctors detect tumor cells circulating in the blood of patients with head and neck cancer, researchers at Emory and Georgia Tech have found.
The detection of circulating tumor cells (CTCs) is an emerging technique tha…
Researchers find reduced levels of an important neurotransmitter in MS
Researchers at the University of Illinois at Chicago have shown for the first time that damage to a particular area of the brain and a consequent reduction in noradrenaline are associated with multiple sclerosis.
The study is available online in t…
Gene protects lung from damage due to pneumonia, sepsis, trauma, transplants
Lung injury is a common cause of death among patients with pneumonia, sepsis or trauma and in those who have had lung transplants. The damage often occurs suddenly and can cause life-threatening breathing problems and rapid lung failure.
The…
Host or foreign — the body’s frontline defense mechanism understood
This week, the highly-respected US Academy of Sciences journal (PNAS) published an article describing how the first line of defence of the human immune system distinguishes between microbes and the body’s own structures. The basis of this recognitio…
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…
