Impaired anti-inflammatory response plays role in pathology of type 2 diabetes

Type 2 diabetes is classified as a metabolic disorder, but a growing number of researchers are beginning to think of it also as a disease of the innate immune system. Inflammation, a key component of the early immune response, is chronically elevated in people with type 2 diabetes.

25,000 genes that have clocks!

A chemical signal acts as time clock in the expression of genes controlled by a master gene called a coactivator, said Baylor College of Medicine researchers in a report that appears in the journal Cell today.

Researchers culture blood-forming stem cells from human fat tissue

Researchers at the University of Pittsburgh School of Medicine have successfully isolated and cultured human hematopoietic stem cells from fat, or adipose, tissue, suggesting that they have found another important source of cells for reconstituting the bone marrow of patients undergoing intensive radiation therapy for blood cancers.
