New Drug To Fight Against Pneumococcal Disease - Scientists Cripple Critical Pneumococcal Proteins
Spain - A new scientific approach of the pneumococcus bacterium could allow the development of a new drug.

The joint study conducted by researchers of Elche (Spain) and Eindhoven (Netherlands) shows that copying the structure of choline in the cell membrane of the bacterium, it is possible to trap the protein binding of choline to the cell and thus making the bacteria less infective.
Phosphocholine, included in an acid used in the composition of the pneumococcal cell membrane, act as a agent host a number of proteins involved in cell division, release of toxins by the bacteria and the adhesion to infected tissues. The choline-binding proteins (CBP), can no longer play their role if they added choline. The cells can then no longer multiply.

Researchers hope to develop a drug based on the copy of the structure of choline-cell disease, choline itself can not be used as medicine. However, the necessary dosage of inhibitor of CBP is within an acceptable range of a pharmaceutical point of view.

1.7 million people die each year from pneumococcal infections such as pneumonia, meningitis and infections of the middle ear. Children and elderly are most affected. The vaccines available that can treat certain types of pneumonia and treatment with antibiotics are available against a resistance of the bacteria.
