Brief Resume

Jeitner, a native of Australia, earned a doctorate in experimental pathology from the University of Sydney. He has held positions at numerous institutions in the US.

Description of Research Interests/Activities

Tom Jeitner has a long-standing interest in the mechanisms by which neurons die. Neurons in the brain are protected from injury by the skull and blood-brain barrier, as well as, the actions of astrocytes and microglial. Similar protections exist for spinal cord neurons. Despite these barriers the central nervous system is vulnerable to variety of insults that can give rise to illnesses as devastating as Amyotrophic Lateral Sclerosis, Parkinson Disease and Alzheimer Disease. The laboratory is investigating the hypothesis that the diseased and aging brain generates neurotoxins through the reaction of hypohalous acids with neurotransmitters. Thus far, our studies have focused on the reaction of dopamine and hypochlorous acid as shown in the model below.
