Outline the potential role of microtubule associated proteins in human neurodegenerative diseases.

Expert Solution

Microtubules present in the cellular cytoskeleton,Microtubules associated proteins are associated with microtubules.It binds to tubulin subunits and makes stability by microtubules.These proteins have different functions like stabilizing and destabilizng microtubules,guiding microtubules to specific locations of the cell,microtubule cross linking and act as a mediator of microtubule interaction with other proteins.

Due to the reduced microtubular stability several neurodegenerative diseases has been observed.Alzheimer;s disease, Parkinsons disease,Amytrophic lateral sclerosis etc.In the case of Parkinson;s disease ,it is associated with mutations and variations in genees encoding microtubular proteins.It is a second common neurodegenerative disease it causes significant degenration dopaminergic neurons of brain.In the case of parkinsons diseaese microtubule interacting proteins like PINK1,LRRK2 and SNCA mutations may cause parkinsonism.Multiple chaperon proteins are depends on physiological tubulin folding,disfunction of protein folding may lead to the formation of toxic misfolded tubulin heterodimers.Microtubule targeting agents are used to treat these microtubule disfunctions.

One of major problems is neuron cell dead and you are interested in neurodegenerative diseases. You are discovered molecule involved in cell survival. Could you please desing your experiments to answer below questions? a)how do you test this molecule protect neuron cell dead? b)if this molecule protect neuron cell dead, how do you test which molecule involved in neuron cell survive? c)how do show this molecule involved neuroprotection in vivo?

essay outlining a few experiments to investigate the potential role of the cytoskeleton (and associated motor proteins) in coronovirus infection.Your proposed experiments will be aimed at determining which, if any, cytoskeletal elements and/7or motor proteins are involved in the infection, replication and dispersal of viral progeny. In this essay, clearly describe the experiments you propose, the cultured cells or tissues you will test, drugs you will use to target specific cytoskeletal elements, and the microscopic & biochemical techniques you intend...

Huntington disease is a rare neurodegenerative human disease determined by an autosomal dominant allele. (Because it is a rare disease, homozygous individuals are also rare.) The disorder is typically a late onset disease with symptoms appearing after the age of 30. A young man has learned that his father has developed the disease. What is the probability that the young man will also develop the disease? What is the probability that a child of the young man develops the disease?
