Proteins necessary for maintenance and function of eukaryotic flagella are synthesized in the cell body. Transport of the inner dynein arm subunit p28(IDA4) in Chlamydomonas flagella requires the activity of the kinesin KHP1(FLA10), a protein inactive at restrictive temperature in fla10, a temperature-dependent mutant of flagellar assembly. To identify other molecules involved in active transpo...

IL-27 is a recently defined family member of the long-chain four-helix bundle cytokines, which consists of EBI3, an IL-12p40-related protein, and p28, an IL-12p35-related polypeptide. The role of IL-27 in the regulation of inflammatory autoimmune diseases has never been studied. The current study uses the DNA vaccination technology, and highly specific Abs to the p28 subunit of IL-27 that were ...

Nogo-A and Nogo receptor (NgR) expression in the visual cortex following a critical developmental period (postnatal days 20-60) has been previously shown. However, little is known regarding Nogo-A and NgR expression between postnatal day 0 and initiation of the critical period. The present study analyzed Nogo-A and NgR expression at four different time points: postnatal day 0 (P0), before criti...

Mycoplasma pneumoniae is a major cause of bronchitis and atypical pneumonia in humans. This cell wall-less bacterium has a complex terminal organelle that functions in cytadherence and gliding motility. The gliding mechanism is unknown but is coordinated with terminal-organelle development during cell division. Disruption of M. pneumoniae open reading frame MPN311 results in loss of protein P41...

BACKGROUND In neonatal rats, early post-hypoxia-ischemia (HI) administration of the omega-3 fatty acid docosahexaenoic acid (DHA) improves sensorimotor function, but does not attenuate brain damage. OBJECTIVE To determine if DHA administration in addition to hypothermia, now standard care for neonatal asphyxial brain injury, attenuates post-HI damage and sensorimotor deficits. METHODS Seven...

We studied the coherent electron transport through metal–protein–metal junctions based on a blue copper azurin, in which ion was replaced by three different metal ions (Co, Ni and Zn). Our results show that neither protein structure nor transmission at Fermi level change significantly upon replacement. The discrepancy with previous experimental observations suggests mechanism taking place these...

Selection of escape mutants with mutations within the target sequence could abolish the antiviral RNA interference activity. Here, we investigated the impact of a pre-existing shRNA-resistant HBV variant on the efficacy of shRNA therapy. We previously identified a highly potent shRNA, S1, which, when delivered by an adeno-associated viral vector, effectively inhibits HBV replication in HBV tran...
