Abstract

Apis mellifera is an organism characterized by having a nervous system structured, with about 950.000 neurons, but have a wealth behavioral and impressive cognitive ability. Currently, the bees have been used as models of learning and memory, highlighting its usefulness for neuroscience, in particular to a better understand the foundations of cognition. For applications in proteomics and peptidomics analysis, bees are good targets because they have their genome sequenced. However, much remains to decipher at molecular level in terms of learning and memory formation in honeybees. In the present study the behavior of "Proboscis Extension Reflex" (PER) is used as input reference for neuroproteomic studies of the bee brain. For this approach to following experimental strategies will be used: I) shotgun proteomics LC-MS/IT-ToF system for analysis of soluble proteins; II) the use of LC-IT-ETD system for analysis of membrane proteins/receptors isolated by BN-PAGE both for proteins identifications, and PTMs assignment. The proteins identified will be quantified by mass spectrometry using the label-free strategy, in order to understand the complex neural network and the memory which the bees will be subjected; III) MALDI Imaging strategy will also be applied to proteins identified by mass spectrometry and some neuropeptides already described in the literature, to understand the distribution of these macromolecules in different brain structures, collaborating with understanding the biological question of this study. The use of different methodological strategies implemented is expected to contribute to the understanding of neuroscience at the level of proteins and peptides and their role in molecular interactions and in the formation of short-term memory in bees.
