Disabling an enzyme may improve brain artery function in aged mice

In an experiment in 18-month-old mice with a partial enzyme deficiency, disabling a second enzyme in blood-vessel lining cells improved abnormal artery responses.In an experiment in 18-month-old mice with a partial enzyme deficiency, disabling a second enzyme in blood-vessel lining cells improved abnormal artery responses.

A brain artery with a wide opening and closely joined lining cells sits beside a constricted gray artery with gaps in its lining and a laboratory mouse.

An immune cell molecule promotes stroke recovery in mice

In mice with induced stroke, guanosine secreted by regulatory T cells promoted meningeal lymphatic growth and fluid drainage to improve recovery.In mice with induced stroke, guanosine secreted by regulatory T cells promoted meningeal lymphatic growth and fluid drainage to improve recovery.

Mouse brains show dense lymphatic vessels with less damage versus sparse vessels with more damage, beside a mouse and immune cells releasing droplets.

Sulfide supplements prevented heart enlargement in aging mice

In a mouse experiment, dietary supplementation begun at 9 months restored metabolic balance in the heart and prevented decline across the body.In a mouse experiment, dietary supplementation begun at 9 months restored metabolic balance in the heart and prevented decline across the body.
