As proof-of-principle, model provides insight into HIV structure.

Scripps Research Institute scientists convert human skin cells into sensory neurons

Scientists have described a way to convert human skin cells directly into a specific type of brain cell affected by Huntington’s disease, an ultimately fatal neurodegenerative disorder. Unlike other techniques that turn one cell type into another, this new process does not pass through a stem cell phase, avoiding the production of multiple cell types, the study’s authors report.

Problem: The assessment of cell concentration and viability is an important step in the characterization of cell health. This information can be used for monitoring proliferation rates, optimizing growth conditions and normalizing cell data for further studies, such as assessing the impacts of cytotoxic compounds.

Current methods rely on multiple, sometimes complex, instrument platforms to provide these answers, reducing flexibility and increasing research costs. Other, simpler methods provide inconsistent results due to their dependence on single-uptake dyes, which do not effectively discriminate between the various states of cell demise. As a result, there is a crucial need for analytical methods that efficiently provide reproducible count and viability data.

By imaging the immune response, researchers have observed how two types of immune cells, T and B cells, interact with one another during a critical period following infection

The fast and safe technique developed at the Salk Institute circumvents problems that have hindered regenerative medicine.

Recently identified cell-cycle controls are targets for new drugs that fight infections by shutting down division.

Antibody therapy could fight second-most deadly strain of virus.

For years, researchers and patients have hoped that embryonic stem cells (ESCs)—capable of forming nearly any cell type in the body—could provide insight into numerous diseases perhaps even be used to treat them. Yet progress has been hampered by the inability to transfer research and tools from mouse ESC studies to their human counterparts, in part because human ESCs are “primed” and slightly less plastic than the mouse cells.

Janelia researchers speed process with new computational method.

Salk scientists identify gene that fights metastasis of a common lung cancer.
