Obligatory intracellular bacterium exploits evolutionarily conserved host signaling pathway to survive

In order to survive, obligately intracellular pathogens exploit host cellular signaling pathways and other cellular processes via molecular interactions between pathogen – secreted “effectors” and host target proteins to reprogram host cell functions.  However, the molecular mechanisms

How do mistletoes use water in leafless hosts?

Mistletoes are parasitic plants that penetrate the bark of the hosts’ branches through a modified root, connecting to their host sap (xylem) from which they access all the water and nutrients they need to survive. The mechanism

Hosts and pathogens: war without end

Theodosius Dobzhansky once famously remarked that “nothing in biology makes sense except in the light of evolution”. Nowhere is this truer than in the never ending struggle between animals and the pathogens (viruses, bacteria and parasites) which
