International Review of Cytology presents current advances and comprehensive reviews in cell biology--both plant and animal. Articles in this volume address topics such as GABA and GABA receptors in CNS and other organs, neuroendocrine control of pheromone biosynthesis in moths, gene transfer to salivary glands, cell type-specificexpression of secretory TFF-peptides in the brain, molecular patterning along the sea urchin animal-vegetal axis, and cell and molecular cell biology of melanin-concentrating hormone. Authored by some of the foremost scientists in the field, each volume provides up-to-date information and directions for future research.
