When eyes are dry, the cornea is more susceptible to injury. By tracking the movements of stem cells (in fluorescent green) in a mouse eye, researchers were able to trace the cells as they differentiated into corneal cells and migrated to the center of the cornea, providing clues about how the cells work to help corneal injuries heal.

Ziyad Al-Aly, MD, a clinical epidemiologist at Washington University School of Medicine in St. Louis and the Veterans Affairs St. Louis Health Care system, examines data from a new study. Researchers led by Al-Aly found that repeat SARS-CoV-2 infections contribute significant additional risk of adverse health conditions in multiple organ systems.

An extended form of the protein aquaporin 4 (red) lines the edges of tiny blood vessels in the brain. Cell nuclei are visible in blue. Researchers at Washington University School of Medicine in St. Louis have found a new druggable pathway that enhances the amount of long aquaporin 4 near blood vessels and increases the clearance of waste from the brain. The findings potentially could lead to new therapies to prevent Alzheimer’s dementia.

Mice engage in grooming behavior, experiencing a phenomenon researchers call pleasant touch. Researchers from the Washington University Center for the Study of Itch and Sensory Disorders have identified a specific neuropeptide and a neural circuit that transmit pleasant touch from the skin to the brain. The findings eventually may help scientists better understand and treat disorders characterized by touch avoidance and impaired social development.
