Langerhans cells migrate to their final destination in multiple waves at different stages of embryonic development
As our primary interface with the outside world, the skin needs to be able to protect itself against infectious threats. Specialized cells known as Langerhans cells (LCs) (see image) are an essential component ...

Branching out: A mathematical law of dendritic connectivity
(Medical Xpress) -- That the brain is evolution at its finest is perhaps best demonstrated by the beauty, complexity and diversity of dendrites – tree-like structures that form neural circuits by connecting ...

Think global, act local: New roles for protein synthesis at synapses
(Medical Xpress) -- How do we build a memory in the brain? It is well known that for animals (and humans) new proteins are needed to establish long-term memories. During learning information is stored at the synapses, the ...

Research shows how PCBs promote dendrite growth, may increase autism risk
New research from UC Davis and Washington State University shows that PCBs, or polychlorinated biphenyls, launch a cellular chain of events that leads to an overabundance of dendrites — the filament-like projections ...

Immune cells with a killer instinct: Tried-and-tested anti-tumour drug displays new effect
Imiquimod, a drug used to treat skin cancer, has been shown to have a previously unknown effect on immune cells. The drug transforms cells known as dendritic cells into "tumour killers" that attack the tumour ...
