TB bacteria mask their identity to intrude into deeper regions of lungs

TB-causing bacteria appear to mask their identity to avoid recognition by infection-killing cells in the well-patrolled upper airways. The bacteria call up more permissive white blood cells in the deeper regions of the lungs and hitch a ride inside them to get into parts of the host’s lungs that are under less surveillance.

Scientists discover how immune cells die during HIV infection; Identify potential drug to block AIDS

Research has identified the chain of molecular events that drives the death of the immune system’s CD4 T cells as an HIV infection leads to AIDS. Further, they have identified an existing anti-inflammatory drug that blocks the death of these cells — and now are planning a Phase 2 clinical trial to determine if it can prevent HIV-infected people from developing AIDS.
