Alzheimer’s Disease and Age-Related Macular Degeneration: Shared and Distinct Immune Mechanisms

Academic Background Alzheimer’s disease (AD) and age-related macular degeneration (AMD) are the leading causes of cognitive impairment and vision loss in the elderly population worldwide. Although they affect different organs (the brain and the retina, respectively), recent studies have revealed shared pathological features, such as β-amyloid (Aβ) ...

Microglia Transcriptional States and Their Functional Significance: Context Drives Diversity

Academic Background Microglia are the only resident macrophages in the central nervous system (CNS) and play critical roles in development, homeostasis, and disease. Traditionally, microglia were viewed as homogeneous “resting” or “activated” states, but the advent of single-cell sequencing technologies has revealed their remarkable transcriptional...
