What is the Origin of Neuroprotection via Hormones?

This field originates from neuroendocrinology, where the protective roles of hormones like progesterone, estrogens, and thyroid hormones on neuronal health have been elucidated. "Neuroprotection" denotes safeguarding nerve tissue structure and function. The "via Hormones" specifies the molecular mediators of this effect.

What is the Mechanism of Neuroprotection via Hormones?

The protective mechanism is multi-faceted, often involving the rapid, non-genomic signaling pathways that modulate ion channel function, thereby preventing calcium influx that leads to excitotoxicity. Furthermore, many neuroprotective hormones act as potent antioxidants, scavenging reactive oxygen species that damage neuronal lipids and proteins. Thyroid hormones, for example, are essential for maintaining mitochondrial respiratory chain integrity in neurons, ensuring a stable energy supply for signaling. This action helps maintain synaptic function under duress.

Neuroprotection via Hormones

Meaning

Neuroprotection via Hormones refers to the specific actions of certain endocrine signaling molecules in shielding central nervous system tissues from damage caused by excitotoxicity, oxidative stress, or ischemia. These hormones act as endogenous buffers, stabilizing neuronal membranes and supporting mitochondrial function within the brain. Understanding this protective effect is crucial for maintaining cognitive integrity, especially during periods of systemic stress or aging. We seek to leverage these natural defense mechanisms.
