Hormones in Invertebrates [PDF]

Nature, 1940
OF recent years increasing attention has been paid to invertebrates to determine whether they provide evidence of chemical correlation similar to those hormonal reactions that are now recognized as being of tremendous physiological and philosophical importance in the life of man and other vertebrates. Even in 1933 the view was held by some workers that

Cell signalling in the immune response of mussel hemocytes [PDF]

Invertebrate Survival Journal, 2006
In this work data on immune cell signallling in the circulating hemocytes of the edible bivalve, themussel Mytilus spp, are summarized. Studies with different bacterial species and strains, heterologouscytokines and natural hormones, as well as with ...

The evolution and variety of RFamide-type neuropeptides: insights from deuterostomian invertebrates [PDF]

, 2014
Five families of neuropeptides that have a C-terminal RFamide motif have been identified in vertebrates: (1) gonadotropin-inhibitory hormone (GnIH), (2) neuropeptide FF (NPFF), (3) pyroglutamylated RFamide peptide (QRFP), (4) prolactin-releasing peptide (

Functional Divergence of Glycoprotein Hormone Receptors [PDF]

, 2010
Two lamprey glycroprotein hormone receptors (lGpH-R I and II) highly similar with gnathostome GpH-Rs were cloned from sea lamprey testes and thyroid, respectively.

Characterization of the neurohypophysial hormone gene loci in elephant shark and the Japanese lamprey: origin of the vertebrate neurohypophysial hormone genes

BMC Evolutionary Biology, 2009
Background Vasopressin and oxytocin are mammalian neurohypophysial hormones with distinct functions. Vasopressin is involved mainly in osmoregulation and oxytocin is involved primarily in parturition and lactation.

Signalling through pigment dispersing hormone-like peptides in invertebrates [PDF]

Progress in Neurobiology, 2011
During recent decades, several research teams engaged in unraveling the molecular structure and the physiological significance of pigment dispersing hormone-like peptides, particularly with respect to colour change and biological rhythms. In this review, we first summarise the entire history of pigment dispersing hormone-like peptide research, thus ...

Steroid Hormones in the Aquatic Environment – Review of the State of Knowledge and Comparison of Surface Water Pollution between Europe and Asia

Studia Ecologiae et Bioethicae
Steroid hormones are fundamental regulators of physiological processes in both animals and humans. The aim of this mini review is to present key findings in recent years regarding the presence and impact of steroid hormones on the natural environment ...

Sulfakinin Signaling Sense Circulating Fructose and Suppresses Food Consumption via Insulin‐Like Peptide in Bactrocera Dorsalis

Advanced Science, EarlyView.
This study discovered a new pathway that tells fruit flies when to stop eating. It found that rising blood sugar (fructose) is detected by a sensor called GR43a. This triggers a chain reaction involving the satiety signal sulfakinin and its receptor, ultimately activating a final satiety signal, ILP5.
