Baby Gap

Life is full of give and take – cells and tissues exchange chemicals with each other, often pushing them through tiny channels in cell membranes. There is another way though, making use of the gaps where cells meet in the epithelium – the skin-like barrier that coats many of our tissues – but what controls this paracellular transport is a little mysterious. Here a mesh of epithelial cells (purple) nestles a developing egg cell in a fruit fly ovary. Pictured under a confocal fluorescence microscope, the cells form triangular junctions that expand or contract to create temporary intercellular spaces (green), long enough for yolk-forming proteins to squeeze through to the egg. With a similar mechanism helping chemicals move from the blood into mammalian testes, future work may unravel the role of paracellular transport in human fertility and development too.

Some animations from the past 2 days for the short film I’m directing :-) keys were done by me and inbetweens done by one of my lovely teammates

Also this one that is just keys atm

[planefood]

been working on a shit ton of class work this week (this is like half of it) Working with my little blood cell and helper T cell guys arent they cute

idk what my thought process was around the T cells design but uhh puppy :-)

In your animation post, is the character with the teardrop shaped head a red blood cell? They're very cute.

both characters in the animation post are blood cells yes :-)

Arc mediates intercellular tau transmission via extracellular vesicles - Research

Tau pathology spreads cell to cell in Alzheimer’s disease, but the molecular mechanisms are unclear. This study found that the capsid-forming protein Arc binds and packages tau into extracellular vesicles that are released from neurons, which eliminates toxic intracellular tau and promotes intercellular tau transmission.

Biologists Find Glutamate-Based Long-Distance Signaling Is Rapid In Plants

With the Arabidopsis as an example, a team of researchers showed that systemic signals in plants begin with the release of glutamate, which is perceived by glutamate receptor-like ion channels. The ion channels then set off a cascade of changes in calcium ion concentration that propagate through the phloem vasculature and through intercellular channels called plasmodesmata. This glutamate-based long-distance signaling is rapid.
