Common inflammation pathway turns anthrax toxin into killer

Bacillus anthracis lethal toxin (LT) is a determinant of lethal anthrax. Its function in myeloid cells is required for bacterial dissemination, and LT itself can directly trigger dysfunction of the cardiovascular system.

Study identifies two stem cell types driving jellyfish tentacle growth

At about the size of a pinkie nail, the jellyfish species Cladonema can regenerate an amputated tentacle in two to three days -; but how? Regenerating functional tissue across species, including salamanders and insects, relies on the ability to form a blastema, a clump of undifferentiated cells that can repair damage and grow into the missing appendage.

Study reveals how tiny tweaks to actin shape our cells

Tiny things matter – for instance, one amino acid can completely alter the architecture of the cell. Researchers at the Universities of Göttingen and Warwick investigated the structure and mechanics of the main component of the cytoskeleton of the cell: a protein known as actin.

Basal spot junctions: A new player in epithelial adhesion and hippo signaling

Australian researchers have discovered a new way that epithelial cells, which form layers in organs like the skin and stomach, attach to one another, and how they perceive growth signals at these attachments, helping them form tissues of the right size and shape.

Scientists develop a method for tracking cellular events over time in living organisms

While physicists continue to argue about whether time is indeed an illusion, as Albert Einstein claimed, biologists have no doubt about its significance for understanding life as a dynamic system.

Scientists reprogram canine stem cells from urine

Dog owners may need to learn to appreciate their best friend's urine. Scientists at Osaka Metropolitan University have devised an efficient, non-invasive, and pain-free method to reprogram canine stem cells from urine samples, bringing furry companions one step closer to veterinary regenerative treatment.
