Cell mechanics and cell-cell recognition controls by Toll-like receptors in tissue morphogenesis and homeostasis

open access: yesFly, 2022
Signal transduction by the Toll-like receptors (TLRs) is conserved and essential for innate immunity in metazoans. The founding member of the TLR family, Drosophila Toll-1, was initially identified for its role in dorsoventral axis formation in early ...

Dorso-ventral heterogeneity in tracheal basal stem cells

open access: yesBiology Open, 2021
The tracheal basal cells (BCs) function as stem cells to maintain the epithelium in steady state and repair it after injury. The airway is surrounded by cartilage ventrolaterally and smooth muscle dorsally.

Calcium mediates dorsoventral patterning of mesoderm in Xenopus [PDF]

open access: yesCurrent Biology, 2001
Calcium signals participate in the differentiation of electrically excitable and nonexcitable cells; one example of this differentiation is the acquisition of mature neuronal phenotypes. For example, transient elevations of the intracellular calcium concentration have been recorded in the ectoderm of early embryos, and this elevation has been proposed ...

Dorsoventral splitting of the infundibulum in a child with pituitary hypoplasia

open access: yesRadiology Case Reports, 2023
Pituitary development arises from ectodermal tissue creating Rathke's pouch and ultimately the adenohypophysis anteriorly whereas neuroectodermal tissue arising from the diencephalon creates the neurohypophysis posteriorly. Alterations in pituitary development can lead to hormonal dysregulation and dysfunction. Following clinical suspicion of pituitary

Evolution of Development: Diversified Dorsoventral Patterning [PDF]

open access: yesCurrent Biology, 2011
Patterning of the dorsoventral axis by graded BMP signaling is conserved in the evolution of animals. However, this system has also proven to be highly adaptable, as is now highlighted by its short-range function in the leech Helobdella.

Cannabinoid Modulation of Excitability and Short-Term Neuronal Dynamics in the Dorsal and Ventral Hippocampus

open access: yesBiology
Endocannabinoids, acting primarily through CB1 receptors, are critical modulators of neuronal activity, influencing cognitive functions and emotional processing.

Nodal signaling is required for mesodermal and ventral but not for dorsal fates in the indirect developing hemichordate, Ptychodera flava

open access: yesBiology Open, 2015
Nodal signaling plays crucial roles in vertebrate developmental processes such as endoderm and mesoderm formation, and axial patterning events along the anteroposterior, dorsoventral and left-right axes.

Ciglitazone—a human PPARγ agonist—disrupts dorsoventral patterning in zebrafish [PDF]

open access: yesPeerJ, 2019
Peroxisome proliferator-activated receptor γ (PPARγ) is a ligand-activated transcription factor that regulates lipid/glucose homeostasis and adipocyte differentiation.

Thoracic radiography of healthy captive male and female Squirrel monkey (Saimiri spp.). [PDF]

open access: yesPLoS ONE, 2018
The purpose of this prospective study was to describe the normal anatomy and provide reference ranges for measurements of thoracic radiography on Squirrel monkeys (n = 13).

Cell type boundaries organize plant development

open access: yeseLife, 2017
In plants the dorsoventral boundary of leaves defines an axis of symmetry through the centre of the organ separating the top (dorsal) and bottom (ventral) tissues.
