The Role of Sex and Sex Hormones in Neurodegenerative Diseases

Abstract

Neurodegenerative diseases (NDs) are a wide class of disorders of the central nervous system (CNS) with unknown etiology. Several factors were hypothesized to be involved in the pathogenesis of these diseases, including genetic and environmental factors. Many of these diseases show a sex prevalence and sex steroids were shown to have a role in the progression of specific forms of neurodegeneration. Estrogens were reported to be neuroprotective through their action on cognate nuclear and membrane receptors, while adverse effects of male hormones have been described on neuronal cells, although some data also suggest neuroprotective activities. The response of the CNS to sex steroids is a complex and integrated process that depends on (i) the type and amount of the cognate steroid receptor and (ii) the target cell type-either neurons, glia, or microglia. Moreover, the levels of sex steroids in the CNS fluctuate due to gonadal activities and to local metabolism and synthesis. Importantly, biochemical processes involved in the pathogenesis of NDs are increasingly being recognized as different between the two sexes and as influenced by sex steroids. The aim of this review is to present current state-of-the-art understanding on the po...Continue Reading

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.

ALS

Amyotrophic Lateral Sclerosis (ALS), also known as motor neuron disease, is associated with the death of neurons that control voluntary muscles. Discover the latest research on ALS here.

Astrocytes & Huntington’s Disease

Astrocytes are abundant within the central nervous system and their dysfunction has been thought to be an important contributor to some neurodegenerative diseases, in particular Huntington’s disease. Damage to these cells may make neurons more susceptible to degeneration. Here is the latest research on astrocytes and Huntington’s disease.
