Abstract:
... We propose to integrate the existing and new experimental data with computational tools to model interaction networks for the most prominent kinetoplastid pathogens. These interaction networks will vastly expand the functional annotation of the kinetoplastid genomes, which in turn are critical for identifying new routes of disease intervention. ...

Abstract:
... This paper examines the vital role played by electron microscopy toward the modern definition of viruses, as formulated in the late 1950s. Before the 1930s viruses could neither be visualized by available technologies nor grown in artificial media. As such they were usually identified by their ability to cause diseases in their hosts and defined in such negative terms as “ultramicroscopic” or invi ...

Abstract:
... Innate immune signaling of plants is initiated by pattern recognition receptors (PRRs) at the plasma membrane. Upon pathogen attack, PRRs recognize pathogen-associated molecular patterns (PAMPs) via ectodomain and lead to signaling cascade via cytoplasmic kinase domain. PAMP-triggered immunity (PTI) activates basal defense responses sufficient to confer broad-spectrum disease resistance by inhibit ...
