Cover picture: Neuromuscular junction of a mouse lacking both α- andβ2-syntrophin. The nerve was labled for neurofilament protein (red), and the acetylcholine receptors were labled with fluorescent α-bungarotoxin (green). In these mice, the acetylcholine receptors are not localized immediately adjacent to the nerve but rather appear as fingers radiating away from the nerve. For details, see the article by Adams et al. in the November 17, 2004 issue (pages 10302–10309).
