Does the minimal kinome of Giardia lamblia illuminate early kinase evolution and unique parasite biology?
The reduced kinome of Giardia sheds new light on early kinase evolution, and its highly divergent sequences add to the definition of individual kinase families as well as offering specific drug targets. Giardia's massive Nek expansion may reflect its distinctive lifestyle, biphasic life cycle and complex cytoskeleton.
Obliterative bronchiolitis was preceded by a decrease in microvascular supply to the small airways (group B). The subsequent onset of airway scarring (groups C and D) was associated with an increased number of significantly smaller vessels, suggestive of neovascularization.
