Immune cells: Phone home

Immune cells communicate with each other with tiny tubes.

"The research not only proves cells other than neurons are capable of long-distance communication, but it reveals a hereto-unknown mechanism cells use for exchanging information."

"Blood-derived dendritic cells and macrophages, both antigen-presenting cells, make use of these so-called tunneling nanotubules to relay molecular messages."

This may explain how the immune system is able to respond so quickly to invasions. Fascinating.
