Researchers discover that capillary obstruction in diabetes, triggered by elevated interleukin-10 signaling, may contribute to cognitive deficits independent of blood sugar levels. Study: A pathogenic ...

The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood ...
