We report a new application of optical coherence tomography（OCT） to investigate the cranial meninges in an animal model of brain injury in vivo. The injury is induced in a mouse due to skull thinning, in which the repeated and excessive drilling exerts mechanical stress on the mouse brain through the skull, resulting in acute and mild brain injury. Transcranial OCT imaging reveals an interesting virtual space between the cranial meningeal layers post skull thinning, which is gradually closed within hours. The finding suggests a promise of OCT as an effective tool to monitor the mechanical trauma in the small animal model of brain injury.

Therapeutic vaccines to boost endogenous T-cell immunity rely on the stimulatory capacity of dendritic cells （DCs）. The functionality of DCs in chronic hepatitis B virus （HBV） infection has been a long-standing debate. Therefore, we have attempted to summarize multiple studies investigating DC function in chronic HBV patients to determine whether common observations can be drawn. We found that the frequency and function of ex vivo-tested myeloid and plasmacytoid DCs were largely intact in patients with HBV infection and similar to those of healthy donor DCs. The main exception was reduced IFN-a production by plasmacytoid DC from chronic HBV patients. This reduced IFN-a production correlated with liver inflammation in multiple studies but not with viral load, suggesting that viral antigens have little effect on DC function. The majority of the confusion about DC function arises from studies reporting the reduced function of healthy donor DCs exposed to various sources of H BV in vitro. These direct effects of viral antigens are in contrast to data from HBV-infected patients. The variations in the assays used and areas that reauire further investigation are also covered
