Neuroendocrinology of Teleosts [PDF]
American Zoologist, 1973 The nucleus preopticus has been shown to receive afferent input from certain cranial nerves and the spinal cord. In addition, the nucleus preopticus and its tracts can synthesize and transport hormones about as rapidly as a mammal can. The nucleus preopticus is functionally involved in the spawning reflex behavior.

Vertebrate Adaptive Immunity—Comparative Insights from a Teleost Model
Frontiers in Immunology, 2017 The channel catfish (Ictalurus punctatus) and the ciliated protozoan parasite Ichthyophthirius multifiliis are used to study pathogen-specific protective immunity.

Fhod3 in zebrafish supports myofibril stability during growth of embryonic skeletal muscle
Developmental Dynamics, EarlyView.Abstract Background Actin filament organization in cardiomyocytes critically depends on the formin Fhod3, but a role for Fhod3 in skeletal muscle development has not yet been described. Results We demonstrate here that in zebrafish mutated for one of two fhod3 paralog genes, fhod3a, skeletal muscle of the trunk appears normal through 2 days post ...

The teleost head kidney: Integrating thyroid and immune signalling
Developmental and Comparative Immunology, 2017 The head kidney, analogous to the mammalian adrenal gland, is an organ unique for teleost fish. It comprises cytokine‐producing lymphoid cells from the immune system and endocrine cells secreting cortisol, catecholamines, and thyroid hormones.

, 2022 Jawed vertebrate species (Gnathostomata) are all characterized by an adaptive immune system based on B and T cells along with the huge diversity and specificity of their antigen receptors, the immunoglobulins (IG) or antibodies and the T-cell receptors (TCRs), respectively.

Role of SoxE transcription factors in development and disease
Developmental Dynamics, EarlyView.Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Epigenetics in teleost fish: From molecular mechanisms to physiological phenotypes.
Comparative Biochemistry and Physiology Part B Comparative Biochemistry, 2018 While the field of epigenetics is increasingly recognized to contribute to the emergence of phenotypes in mammalian research models across different developmental and generational timescales, the comparative biology of epigenetics in the large and ...

Consumer diversity drives stronger predation in tropical marine communities
Ecography, EarlyView.Biotic interactions are predicted to be stronger in the tropics compared to higher latitudes, contributing to observed patterns of global biodiversity. While increased consumer diversity and more complex food webs are expected in tropical communities, the trophic dynamics underlying strong regional effects of predation are not well understood.

Mucosal immunoglobulins protect the olfactory organ of teleost fish against parasitic infection
bioRxiv, 2018 The olfactory organ of vertebrates receives chemical cues present in the air or water and, at the same time, they are exposed to invading pathogens. Nasal-associated lymphoid tissue (NALT), which serves as a mucosal inductive site for humoral immune ...

Animal, 2016 Studies that address fish welfare before slaughter have concluded that many of the traditional systems used to stun fish including CO2 narcosis are unacceptable as they cause avoidable stress before death.
