A pathway involved in the adaptive immune system, a relative newcomer in the world of pathogen defense, may have a more ancient role in protecting cells from invading viruses.

Bioengineered bacteria sneak past solid tumor defenses to guide CAR T cells’ attacks.

A newly identified group of viruses may help suppress eukaryotes’ immune response and promote tolerance of endosymbiotic bacteria.

By Michele Pagano have always gravitated toward order. I may even take it a bit too far according to friends who liken my office to a museum. However, I like to think it not a compulsion, but a Feng Shui approach to life. With this need for order, I may have been better suited to

The Scientist spoke with Jonathan Kagan about his idea that immune cells respond to “errors” made by unsuccessful pathogens, not the pathogens themselves.

Four studies identify alternative origins for cells of the developing lymphatic system, challenging the long-standing view that they all come from veins.
