Researchers at the University of Utah have discovered a naturally-occurring antibody that significantly reduces diabetic symptoms in mice. The study's findings suggest that masking the foreign nature of affected cells may prevent immunological processes that cause diabetes. Eighty percent of treated mice did not develop diabetic symptoms.
A new report from Dr. Anthony-Samuel LaMantia suggests a possible neuro-developmental theory of schizophrenia linked to altered brain development during the first three months of pregnancy. Abnormalities in retinoic acid signaling pathways may contribute to the development of schizophrenia.
A team of scientists, led by Deborah J. Good, has identified a gene called SIL that governs the formation of the left-right body axis during embryonic development. The gene is believed to be crucial in the correct placement of organs such as the heart within the developing organism.
Researchers at NICHD discovered a gene, Lhx5, that controls the development of the hippocampus, a brain structure critical for learning and memory. The gene's inactivation leads to a malformed brain structure, highlighting its importance in complex brain function.
