Abstract
As one of the greatest achievements of medicine in the twentieth century, there has been a dramatic increase in life expectancy and this tendency continues even more rapidly in the twenty-first century. However, this positive achievement also has some negative consequences. The number of patients with clinical memory deficits, including those associated with Alzheimer’s and Parkinson’s diseases, is also on the rise and there is an urgent need for novel drugs and treatment methods. Neuropeptides are widely distributed in regions of the mammalian brain involved in learning and memory and represent targets of memory research. PACAP is one of the peptides that has been found to be vital in memory formation both in vertebrates and invertebrates and provides a promising avenue for research. The use of genetically and physiologically tractable invertebrate model systems will likely lead to the elucidation of fundamental cellular and molecular processes induced by PACAP, due to the numerical simplicity of the brain structures involved. The fruit fly (Drosophila melanogaster) and the pond snail (Lymnaea stagnalis) are two prominent invertebrate model systems that so far have provided valuable insights into the role of PACAP in ageing and memory-related processes, therefore this chapter concentrates on these species.
