New Findings Point to an Abundance of Cellular Riches

Article Abstract:

The annual meeting of the American Society for Cell Biology featured new findings on Salmonella typhimurium, muscle proteins, and sperm. The Salmonella discovery involves understanding how the bacterium tricks cells into helping it via a bacterial protein called SipA. In other findings, the muscle protein titin was found in cell nuclei, where it may play a role in compacting chromosomes before cell division.

The complexities of conception

Article Abstract:

The molecular basis of spermatozoa's cell-specific recognition process is discussed. Study of the cellular mechanisms that control the interactions between sperm and egg could lead to the development of contraceptive vaccines and to advances in the diagnosis and treatment of male infertility.
