Stem Cell Research Helps to Identify Origins of Schizophrenia

New University at Buffalo research demonstrates how defects in an important neurological pathway in early development may be responsible for the onset of schizophrenia later in life.

The UB findings, published in Schizophrenia Research (paper at http://bit.ly/Wq1i41), test the hypothesis in a new mouse model of schizophrenia that demonstrates how gestational brain changes cause behavioral problems later in life – just like the human disease.

Partial funding for the research came from New York Stem Cell Science (NYSTEM).

The genomic pathway, called the Integrative Nuclear FGFR 1 Signaling (INFS), is a central intersection point for multiple pathways of as many as 160

Scientists create mammalian cells with single chromosome set

Researchers have created mammalian cells containing a single set of chromosomes in research funded by the Wellcome Trust and EMBO. The technique should allow scientists to better establish the relationships between genes and their function.

Mammal cells usually contain two sets of chromosomes – one set inherited from the mother and one from the father. The genetic information contained in these chromosome sets helps determine how our bodies develop. Changes in this genetic code can lead to or increase the risk of developing disease.

To understand how our genes function, scientists manipulate the genes in animal models – such as the

Cambridge researchers create mammalian cells with single chromosome set

Berlin, Germany – Stem cell transplant cures HIV in patient

Stem cell transplantation in a 42-year-old HIV patient with leukemia has wiped out the virus from his body, the doctor of Berlin Charité Hospital confirms.
“The patient is fine,” said Dr. Gero Hutter, a haematologist at the Berlin Charité Hospital. “Today, two years after his transplantation, he is still without any signs of HIV disease and without antiretroviral medication.”

The doctor observed that using the stem cells from a donor who carries a unique gene mutation i.e. delta 32 ccr5 along with a tissue match, could now cure the patient from the HIV virus. Delta 32 ccr5 makes the cells resistant
