Ramón Villeda Morales

Ramón Villeda Morales is a neuroscientist whose research examines how aging changes the brain and how blood-borne factors affect brain function.

Saul Villeda: Saul Villeda is a neuroscientist who studies aging and the effects of circulating factors on the brain. His work on blood-borne influences in brain aging overlaps closely with Villeda Morales’s research.
Heterochronic parabiosis: An experiment joins the circulatory systems of young and old animals to test effects of systemic aging factors. This method has been used to test whether young or old blood changes brain aging.
Alzheimer's disease: Alzheimer's disease is a progressive brain disorder that causes worsening memory and other cognitive abilities. Research on aging-related blood signals intersects with questions about vulnerability to neurodegeneration.
GDF11: GDF11 is a circulating growth differentiation factor studied for possible effects on aging tissues. Disputed findings about its abundance and effects illustrate uncertainty in identifying rejuvenating blood factors.
Tony Wyss-Coray: Tony Wyss-Coray is a neuroscientist known for research on aging, blood factors, and neurodegenerative disease. His laboratory’s parabiosis studies helped establish a research context for Villeda Morales’s work.
Blood-brain barrier: The blood-brain barrier is a selective interface that regulates movement of substances between blood and brain tissue. It shapes which circulating signals can influence the brain.
Vascular cognitive impairment: Vascular cognitive impairment is cognitive decline caused by conditions that damage blood vessels or reduce brain blood flow. It links systemic and vascular changes with age-related effects on cognition.
Causal inference: Causal inference is the use of evidence and assumptions to determine whether one factor produces changes in another. Separating a blood factor’s causal action from correlated age changes is a central experimental challenge.
Irina Conboy: Irina Conboy is a bioengineer whose research examines aging and tissue repair through blood and stem-cell biology. Her work on blood-mediated rejuvenation provides a neighboring line of research on systemic aging.
Neurogenesis: Neurogenesis is the production of new neurons from neural stem or progenitor cells. Changes in adult hippocampal neurogenesis are one measured outcome in studies of brain aging.
