Biologists show how the prefrontal cortex, a brain region associated with learning more flexible behaviors, can sometimes block the ability of a mouse to adopt a better way to solve a problem.
The tissue microenvironments surrounding HIV-infected immune cells look a lot like those surrounding cancerous tumors, reports a new Northwestern University study.
The findings help explain why HIV has been so difficult to cure. Scientists found that viral reservoirs exist within tissue microenvironments that resemble immune-suppressive tumor microenvironments, suggesting that future HIV cure strategies may benefit from approaches traditionally used in cancer therapy.
