Alzheimer's disease and other Neurodegenerative Conditions

Materials and Methods Related to the Inflammatory Effects of Secreted Amyloid Precursor Protein

This discovery recognizes the pro-inflammatory activity of a soluble molecule sAPP, which elicits discrete and specific responses from cells of the central nervous system. The pro-inflammatory activity of sAPP has demonstrated the potential to kill neurons. Reduction of this activity would shift the balance of sAPP effects toward greater neuronal viability.

Data indicate that this reduction can be achieved by binding sAPP to apolipoprotein E; design of simpler chemical structures that mimic this binding might have direct therapeutic potential. This shift would be of obvious benefit in conditions that involve accelerated neuron deaths, such as Alzheimer's disease.

The potential uses are in both basic research into the role of sAPP in nervous system functions, and clinical applications to Alzheimer's disease and other neurodegenerative conditions. The goal of this research is to both directly stimulate neuroprotection and dampening pro-inflammatory activity.
