Senolytics Plus TB Drugs Boost Survival in Infected Mice
Based on: Elimination of senescent cells with senolytic drugs as adjunctive host-directed therapy reduces tuberculosis progression in mice.
Tuberculosis triggers some lung cells to become senescent (zombie-like cells that won't die but cause damage). Researchers gave infected mice a senolytic cocktail of dasatinib, quercetin, and fisetin alongside standard TB treatment. The combo improved survival and reduced lung damage, especially in older mice.
Key Insight
This study suggests senolytic drugs may warrant testing as add-on therapy for tuberculosis in humans.

Clearing Out Aging Cells Made Stem Cell Repair Work Far Better in Mice
Old, worn-out cells (called senescent cells) seem to block the body's natural repair work. In mice with liver damage and forced aging, combining a treatment that clears these cells with stem cell therapy worked far better than either alone. The combo reversed signs of aging and restored repair signals. This is early animal research, not tested in people.
How a Cellular Calcium Glitch Speeds Up Aging in Mice
When cells lose control of their calcium balance, it sets off a chain reaction that triggers DNA damage and inflammation tied to aging. In mice, an old antidepressant called mianserin calmed this calcium chaos. It improved several signs of aging and lengthened their lives. This points to calcium control as a possible target for slowing aging.
