Cytoplasmic Dynein Functions in Planar Polarization of Basal Bodies within Ciliated Cells

iScience, 2020
Summary: Despite common consensus about the importance of planar cell polarity (PCP) proteins in tissue orientation, little is known about the mechanisms used by PCP proteins to promote planar polarization of cytoskeletons within individual cells.

Cloned mouse cells with natural killer function and cloned suppressor T cells express ultrastructural and biochemical features not shared by cloned inducer T cells. [PDF]

, 1983
We have examined the morphology, cytochemistry, and biochemistry of mouse leukocyte subsets by analyzing cloned leukocyte populations specialized to perform different immunologic functions.

An efficient high-order algorithm for acoustic scattering from penetrable thin structures in three dimensions [PDF]

, 2007
This paper presents a high-order accelerated algorithm for the solution of the integral-equation formulation of volumetric scattering problems. The scheme is particularly well suited to the analysis of “thin” structures as they arise in certain ...

Signal transduction pathways controlling Ins2 gene activity and beta cell state transitions

iScience
Summary: Pancreatic β cells exist in low and high insulin gene activity states that are dynamic on a scale of hours to days. Here, we used live 3D imaging, mass spectrometry proteomics, and targeted perturbations of β cell signaling to comprehensively ...

Optimal measurement of visual motion across spatial and temporal scales [PDF]

, 2014
Sensory systems use limited resources to mediate the perception of a great variety of objects and events. Here a normative framework is presented for exploring how the problem of efficient allocation of resources can be solved in visual perception ...

Reduced nephrin tyrosine phosphorylation impairs podocyte force transmission and accelerates detachment in disease

iScience
Summary: Podocytes are specialized kidney cells that form the slit diaphragm (SD), an intercellular filtration barrier against plasma protein loss. The SD is subject to significant mechanical strain which can be amplified in disease, leading to podocyte ...

Pvr expression regulators in equilibrium signal control and maintenance of Drosophila blood progenitors. [PDF]

, 2014
Blood progenitors within the lymph gland, a larval organ that supports hematopoiesis in Drosophila melanogaster, are maintained by integrating signals emanating from niche-like cells and those from differentiating blood cells.
