FDC precursor cells exist in the wall of blood vessels

Chronic inflammatory conditions are extremely common diseases in humans and in the entire animal kingdom. Both in autoimmune diseases and pathogen-caused diseases, the inflamed areas are rapidly colonized by antibody producing B lymphocytes - which organize themselves in highly structured areas called "lymphoid follicles".

MiR-125b downregulated in both aggressive and indolent forms of CLL

Loss of a particular microRNA in chronic lymphocytic leukemia shuts down normal cell metabolism and turns up alternative mechanisms that enable cancer cells to produce the energy and build the molecules they need to proliferate and invade neighboring tissue.

$Higher doses of Vitamin D may be most beneficial in reducing bone fractures in older adults$

Higher doses of Vitamin D may be most beneficial in reducing bone fractures in older adults

Based on the results of a pooled analysis of 11 unrelated randomized clinical trials investigating vitamin D supplementation and fracture risk in more than 31,000 older adults, Bess Dawson-Hughes, MD, director of the Bone Metabolism Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University, says higher doses of Vitamin D may be the most beneficial in reducing bone fractures in this age group.

TMC receives NIH grant to evaluate pepducin in heart disease patients

Tufts Medical Center researchers are developing a first-of-its-kind drug to prevent deadly blood clots in heart disease patients, without the risk of serious bleeding associated with current medications. The National Heart, Lung, and Blood Institute of the National Institutes of Health has just awarded the team led by Athan Kuliopulos, MD, PhD, a $10 million grant to start testing a drug based on this novel technology.

Research highlights three factors that could determine outbreak of pandemic flu

A major collaboration between US research centers has highlighted three factors that could ultimately determine whether an outbreak of influenza becomes a serious epidemic that threatens national health. The research suggests that the numbers in current response plans could be out by a factor of two or more depending on the characteristics of the particular pandemic influenza.

Abnormal bone marrow stem cells drive development of myelodysplastic syndromes

Researchers at Albert Einstein College of Medicine of Yeshiva University have found that abnormal bone marrow stem cells drive the development of myelodysplastic syndromes (MDS), serious blood diseases that are common among the elderly and that can progress to acute leukemia. The findings could lead to targeted therapies against MDS and prevent MDS-related cancers. The study is published today in the online edition of the journal Blood.

Safer alternative to experimental gene therapy against HIV infection

Scientists at The Scripps Research Institute have discovered a surprisingly simple and safe method to disrupt specific genes within cells. The scientists highlighted the medical potential of the new technique by demonstrating its use as a safer alternative to an experimental gene therapy against HIV infection.

Blocking AXL protein may prevent resistance to lung cancer drug

People with lung cancer who are treated with the drug Tarceva face a daunting uncertainty: although their tumors may initially shrink, it's not a question of whether their cancer will return—it's a question of when. And for far too many, it happens far too soon.

3D printed templates of filament networks can improve function of engineered living tissues

Researchers are hopeful that new advances in tissue engineering and regenerative medicine could one day make a replacement liver from a patient's own cells, or animal muscle tissue that could be cut into steaks without ever being inside a cow.

Researchers map significant portion of functional sequences of mouse genome

Popularly dubbed "the book of life," the human genome is extraordinarily difficult to read. But without full knowledge of its grammar and syntax, the genome's 2.9 billion base-pairs of adenine and thymine, cytosine and guanine provide limited insights into humanity's underlying genetics.

New toxicology testing method requires lesser number of fish

A new way of testing the safety of natural and synthetic chemicals has been developed by scientists with funding from the Biotechnology and Biological Sciences Research Council (BBSRC). Their research, published today in the journal Ecotoxicology, could reduce the number of fish needed to test the toxicity of a range of chemicals including pharmaceuticals and environmental pollutants.
