AAT protein restores blood glucose in type 1 diabetes model
A protein made by the liver in response to inflammation and used to treat patients suffering from a genetic form of emphysema has been shown to restore blood glucose levels in a mouse model of Type 1 diabetes mellitus, according to a new study led by researchers at Beth Israel Deaconess Medical Center (BIDMC).
Doctors warn patients of HPV link to oral cancer
Ten years ago, most of Dr. Brian Nussenbaum's oral cancer patients were men over 60 who used tobacco and drank heavily. Today, his patients with oral cancer look different. And so does the risky behavior that seems to be leading to their cancer.
A breakthrough, then a surge, in stem cell research
Less than a year after a Wisconsin team helped discover a major alternative to human embryonic stem cells, the Madison scientists say more than 800 labs have begun using the approach, suggesting that many stem-cell researchers are starting to move beyond controversial embryonic sources for their work.
Lack of vitamin D linked to Parkinson's disease
A majority of Parkinson's disease patients had insufficient levels of vitamin D in a new study from Emory University School of Medicine.
Mouse study shows fetal heart can grow cells to repair disease damage
(PhysOrg.com) -- A recent study in mice shows the ability of the fetal heart to grow healthy cells to compensate for cardiac tissue lost to disease. The mice are normal at birth and their hearts function well during their youth. However, these gains can be short-lived. About 40 percent had signs of heart disease in early adulthood, and 10 percent died of heart failure.
Embryonic heart exhibits impressive regenerative capacity
A new study demonstrates that the embryonic mouse heart has an astounding capacity to regenerate, a phenomenon previously observed only in non-mammalian species. The research, published by Cell Press in the October 14th issue of the journal
Developmental Cell, describes the previously unrecognized potential of the embryonic heart to replace diseased tissue through compensatory proliferation of healthy cells.
Response to immune protein determines pathology of multiple sclerosis
New research may help reveal why different parts of the brain can come under attack in patients with multiple sclerosis (MS). According to a new study in mice with an MS-like disease, the brain's response to a protein produced by invading T cells dictates whether it's the spinal cord or cerebellum that comes under fire. The study—from researchers at the University of Maryland School of Medicine in Baltimore and Washington University in St. Louis—will be published online on October 13th in the
Journal of Experimental Medicine.
Biologists spy on the secret inner life of a cell
The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. Those antibodies, donated by transfer across the placenta before birth or via breast milk after birth, help shape a baby's response to foreign pathogens and may influence the later occurrence of autoimmune diseases. Images from biologists at the California Institute of Technology (Caltech) have revealed for the first time the complicated process by which these antibodies are shuttled from mother's milk, through her baby's gut, and into the bloodstream, and offer new insight into the mammalian immune system.
