Centrosome mutations associated with microcephaly are normally thought to result in loss-of-function phenotypes. A new study shows, however, that mutations found in the human microcephaly STIL gene cause centrosome amplification, suggesting a direct link between the presence of extra centrosomes and the establishment of this disease.
Primary microcephaly is a neurodevelopmental disorder that is caused by a reduction in brain size as a result of defects in the proliferation of neural progenitor cells during development. Mutations in genes encoding proteins that localize to the mitotic spindle and centrosomes have been implicated in the pathogenicity of primary microcephaly. In contrast, the contractile ring and midbody requi...
The explosive spread of the Zika virus (ZIKV) through South and Central America has been linked to an increase in congenital birth defects, specifically microcephaly. Representative rodent models for investigating infections include direct central nervous system (CNS) injections late in pregnancy and transplacental transmission in immunodeficient mice. Microcephaly in humans may be the result o...
Microcephaly is a fairly common feature observed in children with delayed development, defined as head circumference less than 2 standard deviations below the mean for age and gender. It may be the result of an acquired insult to the brain, such prenatal or perinatal brain injury (congenital infection or hypoxic ischemic encephalopathy), or be a part of a genetic syndrome. There are over 1000 c...

Emerging infectious diseases have challenged existing public health infrastructure and validated its necessity on the front lines of defense. The 2014-15 epidemic of Ebola virus in west Africa occurred in countries with limited capacity of healthcare facilities and providers and almost no population based health surveillance systems. The Zika virus outbreaks have also previously occurred mainly...
