• The Tau of LRRK2 December 3, 2019   Dense spherical clusters of a protein – called Lewy bodies – are one of the classical hallmarks of the Parkinsonian brain. They are a common pathological feature, but curiously they are not present in all cases of Parkinson’s. For example, some individuals with certain forms of Parkinson’s associated with specific genetic mutations do not exhibit any Lewy bodies. Variations…
• That time APOE met Alpha Syn February 10, 2020    Recently two independent research groups published scientific papers providing evidence that a genetic variation associated with Alzheimer’s may also be affecting the severity of pathology in Parkinson’s. The genetic variation associated with Alzheimer’s occurs in a gene (a functional region of DNA) called ApoE, and the Parkinson’s pathology involves the clustering of a protein called alpha synuclein. Specifically, both…

• Differentiating PD from MSA February 20, 2020   There is a lot of clinical and biological similarities between the neurodegenerative conditions of Parkinson’s and multiple systems atrophy (or MSA). Recently, however, researchers have published a report suggesting that these two conditions may be differentiated from each other using a technique analysing protein in the cerebrospinal fluid – the liquid surrounding the brain, that can be accessed via…

• The inflammasome field is heating up December 6, 2019   When a cell is sick or damaged it will send out signals alerting the immune system that something is wrong. If enough of these molecules are released, they will initate an “immune response” and this process is called inflammation. There is evidence in neurodegenerative conditions (like Parkinson’s and Alzheimer’s) that the inflammation process is involved, and inhibitors of particular…
• T-cells: First responders November 4, 2020 # # # # The cause of the cell loss and pathology associated with Parkinson’s is still unknown. While the later stages of the condition have been well investigated based on various pathological marker (ie Braak staging), the early manifestations of the condition are still a mystery. Cells of the immune system are early responders to any signs of trouble…
