Neuropeptides in the antennal lobe of the yellow fever mosquito, Aedes aegypti.

Siju KP, Reifenrath A, Scheiblich H, Neupert S, Predel R, Hansson BS, Schachtner J, Ignell R - J. Comp. Neurol. (2014)

Bottom Line: The most diverse and versatile neurochemicals in the insect nervous system are found in the neuropeptides.Allatostatin A, allatotropin, SIFamide, FMRFamide-related peptides, short neuropeptide F, myoinhibitory peptide, and tachykinin-related peptides were found to be expressed in local interneurons and extrinsic neurons of the antennal lobe.Building on these results, we discuss the possible role of neuropeptide signaling in the antennal lobe of Ae. aegypti.

Immunolabeling with anti-SIFamide in the AL of Ae. aegypti. Maximum projection of 25 optical sections showing SIFamide immunoreactivity (green) and synapsin (magenta) in the ALs of females (A–C) and males (D–F). Scale bars = 25 μm.

fig04: Immunolabeling with anti-SIFamide in the AL of Ae. aegypti. Maximum projection of 25 optical sections showing SIFamide immunoreactivity (green) and synapsin (magenta) in the ALs of females (A–C) and males (D–F). Scale bars = 25 μm.

Mentions: The SIFamide antiserum labeled a dense meshwork of varicose fibers in the AL that innervated all or most glomeruli without apparent glomerular preference (Fig. 4). Four SIF-immunoreactive cell bodies were found in the pars intercerebralis, with processes in the medial bundle that innervated most brain neuropils (data not shown).
