Is Israel preparing to attack Iran? By David Ignatius, February 2. Defense Secretary Leon Panetta has a lot on his mind these days, from cutting the defense budget to managing the drawdown of U.S. forces in Afghanistan. But his biggest worry is the growing possibility that Israel will attack Iran over the next few months.
Caption: Dendritic and T-cells. Coloured Scanning Electron Micrograph (SEM) of two types of protective cell of the human immune system. A large dendritic or Langerhans cell is seen (at lower right) with a T cell attached (at upper left). Dendritic cells are found in the skin. They recognise foreign proteins (antigens) and ingest them into cytoplasmic Birbeck granules. Antigens are then "processed" and secreted out of the cell, to be dealt with by other immune cells.

Birbeck granules in Langerhans Cell Histiocytosis: Although seldom necessary for diagnosis (but as a historical note), electron microscopy of Langerhans cells demonstrates pentalaminar rod or disc-shaped, racket-like structures (Birbeck’s granules).
