The side-effects of conventional cancer therapy can be devastating. Collateral damage is inevitable with treatments that attack all rapidly dividing cells, which is one reason why targeted biological therapies, such as antibody-based immunotherapies, are gaining traction. But there may be another option... Marie Stark, graduate student at University of California, Davis, USA, and her colleagues in the Department of Molecular and Cell Biology believe that Hepatitis E particles could eliminate...

The lab of Dr. R Holland Cheng focuses on the structural biology of viruses via cryoelectron microscopy (cryoEM), and its scope of interest includes HIV. Recently, we published a paper in PNAS outlining the structure...
The flu virus carries its genes in eight segments of RNA and proteins. Before escaping from a host cell, the virus has to assemble the right pieces and package them into a complete virus. Scientists think that shuffling these segments allows flu viruses to vary from year to year, producing new infectious strains.
R. Holland Cheng, professor of molecular and cellular biology in the University of California (Davis campus), has been developing novel oral vaccinations against enterovirus infections. The novel vaccinations offer an alternative delivery which would replace injections. Cheng has done research in Sweden and in the US and last December he was appointed in the Finland Distinguished Professor Programme.
An international study headed by a UC Davis scientist describes how a component of a potential HIV vaccine opens like a flower, undergoing one of the most dramatic protein rearrangements yet observed in nature. The finding could reveal new targets for vaccines to prevent HIV infection and AIDS.
Hepatitis E virus (HEV) is a feco-orally transmitted, hepatotropic, non-enveloped virus. Insect cell expressed virus-like particles (VLPs) mimic the virus in terms of their stability and integrity in gut environment1 and at extremes of temperature. Additionally, the tertiary structure of the capsid protein is organized such that extensive modification of the surface-protrusion forming domain (P) does not affect the ability of the dimeric building blocks to assemble into VLPs.
