Background: Understanding the proteomes of specific cell types within the brain is crucial for elucidating the mechanisms underlying Alzheimer's disease (AD). However, the isolation and analysis of these diverse and low-abundance cell populations remain significant challenges. This study aims to assess GeoMxTM Digital Spatial Profiler (DSP) by NanoString Technologies (NanoString, Seattle, USA) capable of spatially resolving protein expression profile of AD brains extracted from formalin-fixed paraffin-embedded (FFPE) specimens.

Background: Post-mortem neuropathological examinations following the first active immunotherapy strategy (AN-1792, Elan Pharmaceuticals, 2000) for Alzheimer's disease (AD) have evidenced amyloid-β (Aβ) plaque clearance and increased microglial phagocytic activity in immunised individuals. This study characterises the epigenetic profiles of individuals who underwent Aβ immunotherapy with the aim of discovering novel therapeutic targets and biomarkers.
Method: DNA and RNA was isolated from post-mortem prefrontal cortex tissue of immunised cases (n = 14) who received varying doses (ug) and number of doses during the trial period.
Alzheimers Dement

Massachusetts General Hospital, Boston, MA, USA.
Background: In cognitively unimpaired (CU) older adults, the presence of a subjective cognitive decline (SCD) combined with evidence of abnormal b-amyloid (Ab) is proposed as stage 2 of Alzheimer's disease (AD) by the NIA-AA framework (Jack et al., 2018). However, the associations found between SCD and preclinical AD are inconsistent across studies, highlighting the importance of better understanding which specific SCD features are associated with either Ab or tau burden.

Background: Molariform second premolar is a rare dental anomaly where the second premolar resembles a molar in size and shape. This condition is often linked to macrodontia, a rare enlargement of teeth that disrupts dental proportions and can manifest in isolated, relative, or generalized forms. Although mandibular second premolars are more prone to morphological variability, the occurrence of bilateral molariform premolars, induced by a unique form of gemination, is exceptionally uncommon and infrequently documented, thus making this case clinically significant.
