The central complex is a prominent neuropil found in the middle of the insect brain. It is considered as a higher center for motor control and information processing. Multiple neuropeptides and neurotransmitters are produced in neurons of the central complex, however, distribution patterns and functional roles of signaling substances in this brain region are poorly known. Thus, this thesis focu...

This review discusses the accumulated evidence that pro-opiomelanocortin (POMC) gene products as well other pituitary neuropeptides derived from related genes (Proenkephalin, PENK; Prodynorphin, PDYN, and Pronociceptin, PNOC) can exert direct effects on B lymphocytes to modulate their functions. We also available data receptor systems might be involved in transmission of such hormonal signals c...

Informative parameters of normalized electrograms the brain cats under action regulatory neuropeptides with nootropic properties were established using example Semax drug. The results obtained confirmed by a comparative pharmaco-EEG analysis various pharmacological agents directed action. pronounced stable activating and effects this group in are distinguished unidirectional that coincides data...

Monoamines and neuropeptides interact to modulate most behaviors. To better understand these interactions, we have defined the roles of tyramine (TA), octopamine, and neuropeptides in the inhibition of aversive behavior in Caenorhabditis elegans. TA abolishes the serotonergic sensitization of aversive behavior mediated by the two nociceptive ASH sensory neurons and requires the expression of th...

Energy balance plays an important role in the control of reproduction. However, the cellular and molecular mechanisms connecting the two systems are not well understood especially in teleosts. The hypothalamus plays a crucial role in the regulation of both energy balance and reproduction, and contains a number of neuropeptides, including gonadotropin-releasing hormone (GnRH), orexin, neuropepti...

The critical phylogenetic position of ascidians suggests that evolutionary origins of neuropeptides and hormones of vertebrates are highly likely to be conserved in ascidians, and the cosmopolitan species, Ciona intestinalis, is expected to be an excellent deuterostome invertebrate model for studies on neuropeptides and hormones of vertebrates. Nevertheless, molecular and functional characteriz...
