Malaria impairs T cell clustering and immune priming despite normal signal 1 from dendritic cells [PDF]

open access: yes, 2007
Interactions between antigen-presenting dendritic cells (DCs) and T cells are essential for the induction of an immune response. However, during malaria infection, DC function is compromised and immune responses against parasite and heterologous antigens

Transcriptome analysis provides insights into the mechanism of carapace stripe formation in two closely related Marsupenaeus species

open access: yesFrontiers in Marine Science, 2023
Marsupenaeus japonicus has two types of phenotypic differences that are mainly reflected in the stripe pattern of the carapace. However, the underlying mechanism regulating the stripe patterns is not clear.

Functional neurons and melanocytes induced from immortal lines of postnatal neural crest-like stem cells [PDF]

open access: yes, 2009
Stem cells, that is, cells that can both reproduce themselves and differentiate into functional cell types, attract much interest as potential aids to healing and disease therapy. Embryonic neural crest is pluripotent and generates the peripheral nervous

Correspondences Between Parameters in a Reaction-Diffusion Model and Connexin Functions During Zebrafish Stripe Formation

open access: yesFrontiers in Physics, 2022
Different diffusivities among interacting substances actualize the potential instability of a system. When these elicited instabilities manifest as forms of spatial periodicity, they are called Turing patterns.

MFGE8 does not influence chorio-retinal homeostasis or choroidal neovascularization in vivo [PDF]

open access: yes, 2012
Purpose: Milk fat globule-epidermal growth factor-factor VIII (MFGE8) is necessary for diurnal outer segment phagocytosis and promotes VEGF-dependent neovascularization.

Influence of the polyunsaturated fatty acids linoleic acid, arachidonic acid, [alpha]-linolenic acid and [gamma]-linolenic acid on melanogenesis of B16 mouse melanoma cells and normal human melanocytes [PDF]

open access: yes, 2002
The influence of the polyunsaturated fatty acids (PUFA) linoleic acid, arachidonic acid, α-linolenic acid and γ-linolenic acid on pigmentation was examined using different in vitro models: monolayer cultures of B16 mouse melanoma cells, monolayer ...

Electrogenic sodium-bicarbonate cotransport in human ciliary muscle cells [PDF]

open access: yes, 1992
We investigated membrane voltage and intracellular pH (pHi) in cultured human ciliary muscle cells using a cell line (H7CM) and primary-cultured human ciliary muscle cells.

Early stages of retinal development depend on Sec13 function [PDF]

open access: yes, 2013
ER-to-Golgi transport of proteins destined for the extracellular space or intracellular compartments depends on the COPII vesicle coat and is constitutive in all translationally active cells.

Effect of Photosynthetic Pigment Composition of Tropical Marine Microalgae from Ambon Bay Navicula sp. TAD on Dye-Sensitized Solar Cell Efficiency

open access: yesScience and Technology Indonesia, 2022
Solar cells using dyes as sensitizers continue to expand. The synthetic dye used as a sensitizing material for solar cells has high production costs, difficult to find, and can cause environmental pollution.

The differentiation of cholesterol and pigment gallstones [PDF]

open access: yes, 1989
Gallbladder biles and stones were obtained at 116 cholecystectomies for symptomatic gallstone disease. All 33 patients younger than 50 years had cholesterol stones, whereas 40% of the older patients had pigment stones.
