Alzheimers Dement

Background: Although novel treatments for Alzheimer's disease (AD) have begun to show modest therapeutic effects, agents that target hallmark AD pathology and offer neuroprotection are desired. Erythropoietin (EPO) is a glycoprotein hormone with neuroprotective effects but is faced with challenges including limited brain uptake and increased hematopoietic side effects with long-term dosing. Therefore, EPO has been modified and bound to a chimeric transferrin receptor monoclonal antibody (cTfRMAb); the latter shuttles EPO past the blood-brain barrier (BBB) into brain parenchyma and reduces its plasma exposure and potential for side effects.

Background: The Apolipoprotein E4 isoform (ApoE4), encoded by the APOE gene, stands out as the most influential genetic factor in late-onset Alzheimer's disease (LOAD). The ApoE4 isoform contributes to metabolic and neuropathological abnormalities during brain aging, with a strong correlation observed in APOE4-positive Alzheimer's disease cases between phosphorylated tau burden and amyloid deposition. Despite compelling evidence of APOE-mediated neuroinflammation influencing the progression of tau-mediated neurodegeneration, the molecular mechanisms underlying these phenomena remain largely unknown.

Before committing to an erythroid cell lineage, hematopoietic stem cells differentiate along a myeloid cell pathway to generate megakaryocyte-erythroid biopotential progenitor cells in bone marrow. Recent studies suggest that erythroid progenitors (EryPs) could be generated at the level of common myeloid progenitors (CMPs). However, due to a lack of suitable markers, little is known about the early differentiation of these committed EryP cells during CMP development.

Alzheimer's Disease (AD) is the most common form of dementia and one of the leading causes of death. AD is known to be correlated to tortuosity in the microvasculature as well as decreases in blood flow throughout the brain. However, the mechanisms behind these changes and their causal relation to AD are poorly understood.
