Volume 9 Issue 11, November 2003

Directing immune responses to kill tumor cells - by induction of apoptosis, for example - is a major goal of cancer immunotherapy. In this issue, Padua et al. (page 1413) present a vaccine strategy for treating promyelocytic leukemia, and Rubio et al. (page 1377) demonstrate a new method for detecting vaccine-induced tumorcytolytic T cells. The cover image shows a healthy human myeloid cell (upper cell) and a myeloid cell undergoing apoptosis (lower cell). Magnification, x11,000. Courtesy of Gopal Murti/Photo Researchers Inc.

  • Molecules that regulate contraction in skeletal muscle have now found a place in the axon. In response to injury, the ryanodine receptor mediates the release of internal calcium stores, which contributes to axonal damage.

  • Artemin reverses pain and neurochemical changes after nerve injury in an animal model. The molecule could potentially treat neuropathic pain, in which even the slightest touch can hurt (pages 1383–1389).

  • Effective cancer vaccines targeted against specific antigens have eluded researchers for decades. When combined with a drug, one such vaccine now shrinks tumors in a mouse model of promyelocytic leukemia (pages 1413–1417).

  • M. tuberculosis persists in the body, sequestered inside macrophages and subverting the phagocytic machinery to create a membrane-bound home. Microarray profiling studies reveal how the bacterium settles into its new environment.
