A novel pathway regulates thyroid hormone availability in rat and human hypothalamic neurosecretory neurons. [PDF]

open access: yesPLoS ONE, 2012
Hypothalamic neurosecretory systems are fundamental regulatory circuits influenced by thyroid hormone. Monocarboxylate-transporter-8 (MCT8)-mediated uptake of thyroid hormone followed by type 3 deiodinase (D3)-catalyzed inactivation represent limiting ...

Neural mechanisms of parasite-induced summiting behavior in ‘zombie’ Drosophila

open access: yeseLife, 2023
For at least two centuries, scientists have been enthralled by the “zombie” behaviors induced by mind-controlling parasites. Despite this interest, the mechanistic bases of these uncanny processes have remained mostly a mystery.

Ring neurons in the Drosophila central complex act as a rheostat for sensory modulation of aging.

open access: yesPLoS Biology, 2023
Sensory perception modulates aging, yet we know little about how. An understanding of the neuronal mechanisms through which animals orchestrate biological responses to relevant sensory inputs would provide insight into the control systems that may be ...

Digestive system of the hepatotrematode Parafasciolopsis fasciolaemorpha Ejsmont, 1932 (Plathelminthes, Trematoda): morphofunctional organization, histological and histochemical features to adaptive specialization

open access: yesРоссийский паразитологический журнал, 2022
The purpose of the research is to study the morphofunctional organization, histological and histochemical features of the digestive system of the marita Parafasciolopsis fasciolaemorpha, which provide adaptation to parasitism in the endostasis – the ...

An FXPRLamide neuropeptide induces seasonal reproductive polyphenism underlying a life-history tradeoff in the tussock moth. [PDF]

open access: yesPLoS ONE, 2011
The white spotted tussock moth, Orgyia thyellina, is a typical insect that exhibits seasonal polyphenisms in morphological, physiological, and behavioral traits, including a life-history tradeoff known as oogenesis-flight syndrome.

Fifty Years of Advances in Neuroendocrinology

open access: yesBrain and Neuroscience Advances, 2018
Importance of the neuroendocrine brain for health and happiness has become clear since the 1960s. Foundations laid 100 years ago culminated in Geoffrey W Harris’s model of control by the brain of secretion of anterior and posterior pituitary gland ...
