What's next for gene therapy? Plastic

..., Va., Sept. 13, 2006 -- Gene therapy depends upon foreign DNA, even viruses, to deliver genes, therapeutic proteins, or medicine to cells within the body. Many scientists are looking for better chaperones across the cell membrane. Virginia Tech researchers think polymer molecules can be created to do the j...

Protein splicing upsets the DNA colinearity paradigm

...asomes,' components of the cell machinery that cut foreign proteins into peptides that are then displayed on the cell surface for recognition and destruction by CD8+ T lymphocytes. However, the Belgium/USA team has found that proteasomes can also splice the peptide fragments together in a reverse order to th...

Study illuminates how the plague bacteria causes disease

...cells of the immune system to track down and "eat" foreign invaders, the researchers explained. The discovery marks the second way in which this protein, called YpkA, compromises the immune system. Earlier studies suggested that another portion of YpkA--which may have been derived from a mammalian enzyme a...

Fishing trade helps Africa

...rkets, especially in Europe, are a major source of foreign exchange revenue. The fish export trade also helps to underpin the operation of domestic fisheries, which provide a basis for the livelihoods and employment of thousands of local people, mainly in coastal regions. The export trade from West Africa ...

UCLA study uncovers new risk factor for schizophrenia

...inguish the body's own proteins from those made by foreign invaders, such as viruses and bacteria. The developing fetus inherits one copy of the HLA-B gene from each parent. "Our findings clearly suggest that schizophrenia risk rises, especially in daughters, when the child's HLA-B gene too closely match...

A 'recent' embosymbiont -- a rare evolutionary example -- offers clues to how plants came to be

...d endosymbiont and led to the establishment of the foreign cell as a permanent photosynthetic organelle. Prior data indicated a recent plastid endosymbiosis in Paulinella, but lacked information about the properties of the plastid genome. In the new work, Dr. Bhattacharya and colleagues generated DNA libra...

Impact of forest certification in developing countries examined

LIAI scientists identify immune system trigger for fighting Lyme disease

...onenberg said. Most white blood cells respond to foreign proteins to protect the body, but NK T cells are unique in that they respond to glycolipids, which are natural biochemicals made of linked fat and sugar.

Contagious cancer in dogs confirmed; origins traced to wolves centuries ago

...like there is an aggressive phase of growth as the foreign tumor initially isn't recognized by the immune system," Murgia said. "In the long run, the immune system gets the better of it." "As a sexually transmitted cell, CTVT would not have been able to colonize dogs worldwide if it killed them too quickly...
