Alzheimer 's disease ( AD ) is qualify by the accretion of misfolded amyloid ( A ) and tau protein in the brain , lead to the loss of neural connection . astrocyte and microglia , particular type of brain cell , experience reduce glucose metamorphosis in AD . astrocyte play a crucial function in supply energy to nerve_cell by breakage down glucose into lactate and provision it to nerve_cell . A Holocene survey light-emitting_diode by Dr. Katrin Andreasson at Stanford University investigate the enzyme indoleamine-2,3 - dioxygenase 1 ( IDO1 ) in astrocyte , which is associate to AD . The research , support by NIH support , uncover that A and tau protein promote IDO1 degree and activity in astrocyte , suppress glucose conversion to lactate . suppress IDO1 restore lactate production in the presence of A and tau , bespeak a potential treatment approach for AD.
Contrary to the conventional belief that amyloid plaque lend to Alzheimer 's disease , research_worker at the University of Cincinnati propose that low degree of healthy A42 protein are associate to the disease . The survey propose that elevation A42 degree in the brain could decelerate cognitive decline in Alzheimer 's patient . new Alzheimer 's treatment inadvertently increase A42 degree , lead to positive effects on cognition . The research_worker analyze data from over 26,000 Alzheimer 's patient across 24 clinical test and found that elevated_railway A42 degree were associate with slow cognitive damage and clinical decline . The survey challenge the premise that solely focus on remove amyloid plaque is the solution to Alzheimer 's , highlight the significance of restore A42 protein to convention levels.
In decision , understanding the intricate mechanism underlie Alzheimer 's disease and research advanced treatment scheme are crucial stairs towards battle this complex neurodegenerative condition.
