Insect Neuropeptides - Kinin

Introduction

The first members of the kinin family were isolated from extracts of the cockroach Leucophaea maderae using a hindgut contraction assay where the peptides were found to be myostimulatory (Holman et al, 1986; Holman et al, 1987). These eight peptides were designated leucokinin I – VIII (LK-I – VIII). Subsequently kinins have been identified in most insect species (except Coleoptera). The first kinin-encoding gene was cloned from the mosquito Aedes aegypti in 1997 (Veenstra et al, 1997). From this precursor 3 kinin peptides can be cleaved. Ensuing studies have identified precursors with varying numbers of kinin peptides, depending on species. In the blood-sucking bug Rhodnius the precursor encodes 12 copies of kinin (Te Brugge et al, 2011). The active core of the kinins resides in the conserved carboxyterminus pentapeptide FXSWGa (Nachman and Pietrantonio, 2010), and the peptides can vary in length between 6 and 16 residues. The first kinin receptor (GPCR) was identified from D. melanogaster in 2002 (Radford et al, 2002). Each species analyzed to date appears to have a single kinin receptor.

Location

Kinin peptides were first mapped to neurons and neurosecretory cells in the brains and abdominal ganglia of L. maderae, a few blowfly species and in D. melanogaster and later in other insects (Cantera and Nässel, 1992; Chen et al, 1994; Nässel et al, 1992). In most studied insects kinins are produced in bilateral pairs of neurosecretory cells in segmental abdominal ganglia, and the peptides are likely to serve hormonal functions. Kinins are also produced in CNS interneurons of varying numbers, depending on species (Cantera and Nässel, 1992; Chen et al, 1994; Nässel et al, 1992).

Function

The first identified functions of kinins were myostimulatory activity on visceral and reproductive muscle, as well as stimulation of secretion in renal tubules (Coast et al, 1990; Holman et al, 1987; Schoofs et al, 1993). The mode of action on renal tubules has been extensively studied in several insect species (Dow, 2009; Radford et al, 2002). In D. melanogaster additional functions have been inferred from genetic studies: regulation of sleep, meal size during feeding and a role in desiccation resistance in adult flies (Al-Anzi et al, 2010; Cannell et al, 2016; Liu et al, 2015), and in larvae kinins modulate locomotor behavior and are important in the hormonal cascade triggering ecdysis behavior (Kim et al, 2015; Okusawa et al, 2014; Murakami et al, 2016). Kinins have only been identified in invertebrates, including numerous arthropods, nematodes, annelids and mollusks. Interestingly, a kinin-like receptor has also been identified in Ambulacraria (deuterostomian invertebrates).
